Sugarcane, Indians, and Roundup, Professor Geoffrey Norris, SLR/IRL

Today I share the second paper of guest, Geoffrey Norris Ph.D. I recently shared Blue-green algal blooms in the lakes, rivers, and marine waters of south Florida surrounding Lake Okeechobee.

I must admit, I hesitated publishing this second paper, “Sugarcane and Indians,”  as I  am sure some may interpret it as “politically incorrect.” I apologize to anyone who may, but I decided to print Dr Norris’ paper because the main message is important.

The message is:

“Is Sugar’s use of ripening stalks with “Roundup” feeding toxic algae blooms and why are lands/waters south of Lake Okeechobee “protected” while ours of the northern estuaries are not? “

You will learn something about this in Dr Norris’ paper below, and I thank him for sharing his work.

In closing, I believe we have something important to learn from history and the Native People of North America; I admire them. They are great warriors and respect Nature, the gift of our Creator. And in the case of the Miccosukee, they “never surrendered” and if I have anything to do with it, neither will we.

unknown.jpgSugarcane and Indians

Executive summary

  • The area around Lake Okeechobee accounts for almost half the total production of sugarcane in the United States.
  • Sugarcane in south Florida is very needy of phosphorus and potassium fertilizers, but nitrogen fixed in the muck soils largely eliminates the need for extra nitrogen fertilizers.
  • Sugarcane also demands the use of the phosphorus-rich herbicide “Roundup” (glyphosate) several times each year. Firstly, in the fallow season (approximately May-September) to control weeds and allow the sugarcane underground rhizomes to regenerate.  Secondly, as the new shoots come through in the Fall to continue weed control.  Thirdly, during maturation and harvesting (October through March) glyphosate is applied to “chemically ripen” the sugarcane and improve sugar yields.
  • Land south of Lake Okeechobee could be used for storage and bio-cleansing of excess lake water. However, the 1997 water quality agreement between the Environmental Protection Agency and the Miccosukee Indians (aka Mikasuki, Miccosuki) states that phosphorus shall not be present in quantities greater than 10 parts per billion, and that no substance shall be present to stimulate algal growth and produce objectionable algal densities in the 300,000 acres of tribal lands in the Everglades south of Alligator Alley.
  • This legal agreement would suggest that Lake Okeechobee waters destined for southern storage must be cleaned to rigorous standards before discharge into southward flowing streams feeding the Everglades, at least near the Miccosukee tribal lands.
  • A case could be made for the sugar industry and related agriculture to “clean up its act” to mitigate the effects of heavy fertilizer and herbicide usage on the environment in general and on lake and stream waters in particular.

Sugarcane and Indians

First about nutrients and farm land and how much is planted in sugarcane.

Here are three maps that graphically answer the question about the extent of sugarcane plantations:unknown.jpg

1__#$!@%!#__unknown.gifunknown.png

A couple of years ago I had the opportunity the fly over the area south of Lake Okeechobee in a light plane at about 1000ft altitude.  The extent of the sugarcane is truly mind-boggling. Its plantations surround the entire southern perimeter of the Lake and reach to the horizon.  Smaller plantations occur elsewhere around the Lake.  It is a very big operation.

Now to the nutrients themselves.  I had a great deal of difficulty finding precise information on how much fertilizer is applied per unit area.  There were general articles that confirmed that sugarcane is very needy of nitrogen, phosphorus, and potassium fertilizers together with other elements. It is after all a giant grass, so just think how much stuff you have to put on your own lawn to make it grow green!  Apparently, in the south Florida area the need to apply nitrogen fertilizer to sugar cane is not so critical because the mucky soils generate their own nitrates through soil microbial activity.  However, phosphates must be applied as  fertilizer for sugarcane at various times of the year together with potassium etc.  But actual numbers were hard to come by, other than that sugarcane is voracious for fertilizers.  This is when I stumbled upon some marvellous work that the U.S. Geological Survey has been doing on the extent and the total quantitates of pesticides being applied to farmland across USA.  I used their maps of glyphosate (Roundup) as what I thought might be a reasonable proxy for phosphate fertilizer.  In other words, if you use Roundup as a weedkiller on crops, then very likely you will be using fertilizer as well.  It turns out I was right and I was wrong!  First take a look at this summary map for two separate years, 1992 being the earliest year available in this USGS study:

Details are difficult to see in these summary maps but the originals are much clearer.  The area around Lake Okeechobee was already in 1992 applying large amounts of glyphosate, and this intensified in succeeding years.  What I didn’t understand was why the sugarcane fields should be so needy of weedkiller – fertilizers OK, but why so much weedkiller?  It would seem that 25% of the cost of sugar production is due to heavy nutrient need (up to 75 lbs phosphate per acre, with 400,000 acres in sugarcane in south Florida).  But weedkiller.  Then I dug deeper following your email comments and found out why.  Indeed glyphosate is used at least three ways on sugarcane as follows:

Firstly, during the fallow season (approx. May-September 2016) following harvesting, glyphosate is applied to control weeds which would otherwise grow up and choke out the underground cane sugar rhizomes left in the ground to regenerate as the next crop.

Secondly, glyphosate application continues in different amounts as the new shoots come through in the Fall.  This is tricky because glyphosate kills just about anything that is green, but careful control can kill the young weeds while not harming – at least not very much – the young sugarcane shoots.  Other herbicides are also involved but glyphosate is the big one.

Thirdly, the sugarcane matures and is harvested in the winter months at various times from October through March.  During this time the stem of the sugarcane ripens and becomes rich in sugar (sucrose) prior to going to the mill.  Astonishingly (to me anyway) it has been found that about a month or two prior to harvesting, another application of glyphosate will help ripen and enrich the crop with significantly more sugar.  This process is called “chemical ripening”.  Other chemicals can be involved but glyphosate is a popular choice (it got cheaper once Monsanto’s patent expired in the year 2000).

So yes, I think cane sugar farming is being pursued intensively, but I’m not sure how it can be stopped.  Its effects on Lake O could be mitigated as discussed in my previous document but stopping an entire industry would be almost impossible to my mind.  Cleaning up the sugar industry might be a more realistic aim.
Change of land usage and water flow.

It would be nice to think that Lake Okeechobee water could be redirected southwards along its original historic course on its way to the Everglades.  Here’s a graphic of how things used to be:
1__#$!@%!#__unknown.jpg
For thousands of years, water drained from Lake O through a wide series of shallow tributaries and interconnected lakes to the Everglades.  It’s unlikely that this could be recreated but certainly use of land south of the Lake for water transport and storage and bio-cleansing of some sort or another would be an improvement.  However, it would seem that this is unlikely given the actions of the U.S. Environmental Protection Agency and its agreement in 1997 re the  Clean Water Act with the Miccosukee Indians, a tribe which occupies part of the Everglades.

https://www.epa.gov/sites/production/files/2014-12/documents/miccosukee.pdf

This agreement set out comprehensively water quality standards for the Tribes drinking water, wildlife habitat water, and recreational water (boating, swimming etc).  In particular, Section 3 reads:
MICCOSUKEE ENVIRONMENTAL PROTECTION CODE
SECTION 3. Tribal Water Quality Standards

The following minimum water quality criteria shall apply to all surface waters of the Miccosukee Tribe of Indians of Florida unless those water bodies are designated with higher or stricter water quality standards. Stricter standards for a given water body shall supersede these general Water Quality Standards. These standards shall provide a legal basis for including whole effluent toxicity requirements in all federally issued permits.

(there follows a list of 16 physical, biological, and toxicological conditions of which these two are particularly germane):

E. NUISANCE CONDITIONS: Plant nutrients or other substances stimulating algal growth, from other than natural causes, shall not be present in concentrations that produce objectionable algal densities or nuisance aquatic vegetation, or that result in a dominance of nuisance species instream, or that cause nuisance conditions in any other fashion. Phosphorus and nitrogen concentrations shall not be permitted to reach levels which result in man-induced eutrophication problems. Total phosphorus shall not exceed 10 parts per billion in Class III-A waters. In Class III-B waters, total phosphorous discharges shall not be made which result in undesirable aquatic life effects or which result in chronic or acute toxicity to aquatic life.

N. NUTRIENTS: In no case shall nutrient concentrations of Tribal Class I or Class III-A surface waters be altered so as to cause an imbalance in natural populations of aquatic flora or fauna. Total phosphorus concentrations shall not exceed 10 parts per billion in Class III-A waters. In Class III-B waters, nutrients shall not be discharged which result in undesirable aquatic life effects or which result in chronic or acute toxicity to aquatic life.

So what this and other sections of agreement mean is that nutrient-rich water from Lake Okeechobee must be cleaned to rigorous standards before discharge into southward flowing streams feeding the Everglades.  So bio-cleansing within the Everglades – or at least near the Miccosukee tribal lands (about 300,000 acres in the vicinity of the Tamiami Trail and Alligator Alley) is not a possibility within this legal framework.

2__#$!@%!#__unknown.gif

However what’s good for the goose is surely good for the gander.  I looked into the history  of the Miccosukee Indians, and it would seem they are only fairly recent arrivals in Florida, arriving about the same time as Stuart was being settled.  The Miccosukee appear to have originated in what is now Georgia and then migrated south to north Florida where they became entwined with the Seminoles.  After the Seminole wars of the 19th century they migrated to central Florida in the late 1800’s and then decided to disentwine themselves from the Seminoles as a culturally distinct society.  They appear to have seen an opportunity during the construction of the Tamiami Trail in the first quarter of the 20th century and migrated further south and became embedded in the adjacent Everglades. First  Florida (1957) then federally (1962) they became recognized as a tribe distinct from the Seminoles.

Meanwhile in th early 20th century, as the migrant Miccosuki Indians were settling down in their new home in the Everglades as “Trail Indians”, Stuart was incorporated as a town (1914) then a city (1925) after being settled by migrant northerners about half a century earlier.  Total population of Stuart is now about 16,000.

640 migrant Indians – how many are fishing  and frogging?  16,000 migrant non-Indian northerners – how many lives and livings are being disrupted by ruined beaches and waterfronts?
the Indians pushed for a great deal from EPA and got it.  So now a total of about 640 Miccosukee (Mikasuki) Indians (some now  living in Miami-Dade and not the Everglades) can pursue their supposedly traditional way of life (fishing, frogging, subsistence agriculture) plus gaming resorts and casinos and tobacco shops – while many of the 151,000 citizens of Martin County are prevented from pursuing their traditional way of life.  Surely our waters (habitat, recreational, drinking) should be subject to the same rigorous standards as laid down by the EPA/Clean Water Act for the people living in the Everglades.

We are all equal – as George Orwell said – but some are more equal than others.  Well, so it seems.  What do you think?

Is Agriculture’s Use of Glyphosate Feeding Lake O’s Explosive Algae Blooms? Professor Geoffrey Norris, SLR/IRL

Writing my blog allows me to meet many interesting people. Recently, fellow Sewall’s Point resident, and active Vietnam Veterans of America member, Mr. Frank Tidikus, introduced me to Canadian and part-time Martin County resident, Professor Geoffrey Norris who is a geologist and algae fossil specialist with a long career at the University of Toronto.

Professor Norris, his wife, and I met at the Prawnbroker and had a lovely exchange. Dr Norris describes himself as such…

Professor Norris shared two papers composed for his property association at Indian River Plantation on Hutchinson Island along the Indian River Lagoon during the 2016 toxic algae extravaganza. Today, I will share the first entitled: “Blue-green algal blooms in the lakes, rivers, and marine waters of south Florida surrounding Lake Okeechobee.” His second, specifically on Sugarcane, I will provide next week.

Professor Norris’ summary and full paper is below. It is excellent in that it is able to relay complex subjects to the everyday reader interested in water quality and improving the plight of our St Lucie River/Indian River Lagoon.

What is most amazing to me are his comments on glyphosate, most famous for being the active ingredient in Roundup, but now used under many names. Sometimes I hear people screaming so much about Roundup that I tune it out, but Professor Norris’ observations really got to me.

He notes that glyphosate, used excessively in agriculture production around south and central Florida may actually “feed”cyanobacteria (toxic blue-green algae blooms). Also mind-blowing are Professor Norris’ insights into the reproduction of the hungry and ancient cyanobacteria that reproduces through binary fission (copying itself) “producing endless clones” “with no dissipation of mutant genes as a checks and balance to adaptation…”

Yikes! Really?

Blue-green algal blooms in the lakes, rivers, and marine waters of south Florida surrounding Lake Okeechobee 

Executive Summary

  • This report provides basic information on blue-green “algae” and explains that they are actually bacteria (cyanobacteria). These blue-green bacteria form blooms in Lake Okeechobee that in turn are released by the Army Corps of Engineers into canals and estuaries of south Florida.
  • The blue-green bacteria grow by using sunlight as an energy source to synthesize elements from the water into more complex compounds used in their cells. When important nutrients such as phosphorus and nitrogen are present in excess, the bacteria multiply rapidly and accumulate as highly concentrated masses of cells, called blooms.
  • Blue-green bacteria can synthesize nitrates from atmospheric nitrogen, but also need phosphorus dissolved in water to survive and thrive. If phosphorus is scarce in the water, this limits the growth of the bacteria.  If it is abundant, blooms can be triggered.
  • Run-off and back pumping into Lake Okeechobee from surrounding Everglades agricultural lands and upstream from the Kissimmee River watershed is suspected of providing a potential abundant source of phosphorus for blue-green bacteria, in phosphate-rich fertilizers and herbicides such as Roundup (glyphosate).
  • Glyphosate (2-[(phosphonomethyl)amino]acetic acid) is of particular concern, since it has been used heavily in the agricultural areas around Lake Okeechobee and upstream in the Kissimmee River watershed for at least 25 years. Glyphosate provides a source of phosphorus for blue-green bacteria and recent research by others suggest that glyphosate enhances the growth of blue-green bacteria, which become tolerant and absorb glyphosate directly.
  • The blue-green bacterial blooms released into the St Lucie Estuary (principally Microcystis) are formed in freshwater but appear to be tolerant of dilute salinities, and recent research suggests can build up resistance to increased salinities such as are found in estuarine waters.

Introduction

I am a property owner in Stuart, Florida and have been alarmed – along with many others – at the spread of blue-green algae (aka cyanobacteria) into the St Lucie River and adjacent areas by water releases from Lake Okeechobee.  There has been much publicity and calls for action over the years but very little appears to have been done to solve this long-standing problem at any level of government, until very recently.  Now, a State of Emergency has been declared by the Governor of Florida.  Recent initiatives, following public meetings in Martin County thanks to the Board of County Commissioners, have been undertaken by Florida Representative Gayle Harrell and Senator Joe Negron and their colleagues in association with Senators Marco Rubio and Bill Nelson and Rep. Patrick Murphy to urge the Army Corps of Engineers to stop immediately the nutrient-laden discharges from Lake Okeechobee.

Although I am a property owner and tax payer in Martin County, I am also a Canadian snowbird and therefore do not have a vote, which is a little constraining when trying to influence political decisions.  Therefore, I decided to put my energies into assessing what is known about the current situation of the blue-green blooms.  I am a geologist by training and I do have a specialized knowledge in particular of fossil algae that have been extremely important in oil and gas exploration over the decades gone by.  I am not a biologist but I do have some knowledge of the literature on algae – their ecology, morphology and distribution in various environments.  I have published hundreds of scientific papers on fossil algae and related topics and hope that the following – largely based on biological and agricultural literature – will pass muster.

In the following presentation my aims are twofold:

Firstly, to try and answer commonly asked questions about blue green algae (which are actually bacteria) that might be helpful in clarifying some of the technicalities of a complex subject.

Secondly, to highlight what to my mind is the ultimate cause of the blue-green outbreak:  that is, the heavy application of phosphate-bearing fertilizers and herbicides around Lake Okeechobee together with back pumping of agricultural run-off into the Lake.  In particular I believe that the well-known weed killer glyphosate (e.g. Roundup) may be implicated as a major contributor to the problem.  South Florida and somewhat later Central Florida became major users of Roundup in the early 1990s, long before its popularity spread north into the corn and bean belt.

Feel free to pass this article on to others.  I would welcome comments by email at rosalex@interlog.com

What are blue-green algae?

Well, for starters they are not actually algae at all.  They were discovered in the 19th century by biologists using newly invented high-powered microscopes. They noticed a variety of microorganisms living in water, some of them with green pigments in the cells that allowed photosynthesis to occur, similar to the well-known photosynthesis occurring in the much larger land plants and driven by chlorophyll.  But they were much simpler in organization than the large land plants so were called “algae” (singular alga, from the Latin word for seaweed).  Some of these microorganisms contain a rather different bluish pigment and were therefore referred to as “blue-green”, and in these early days were judged nevertheless to be algae – hence blue-green algae.

It was only later that biologists realized that the blue-green microorganisms were crucially different from algae because they had no nucleus in the cell and their pigment was not organized into a “blob” within the cell like most other algae.  In the scientific literature they are now regarded as bacteria and the blue-greens are referred to as cyanobacteria – that is, photosynthetic bacteria that use a blue-green pigment to facilitate the use of the sun’s energy to produce organic compounds needed by these organisms.

It is important to understand this difference between the blue-green cyanobacteria on the one hand and the “true” algae on the other.  I will come back to the difference between bacteria and algae later, and how this impacts on bloom formation.

Meanwhile, the term “blue-green algae” has gained traction in the news media and is now widely understood to be implicated in the blooms of microorganisms that occur from time to time in lakes and rivers in Florida and elsewhere.  I will use either of the terms “blue-green algae” or  “cyanobacteria” depending on the context, or just the neutral term “blue-greens”.  But remember they are actually bacteria.

What are algal blooms?

An algal bloom is the result of rapid increase or accumulation of algae in a body of water.  They can occur in freshwater (lakes, rivers) or in marine water (estuaries, lagoons, coastal embayments).   Different types of algae (including the blue-green cyanobacteria) produce different blooms characterized by green, bluish, yellow, brown or red colors.  The density of pigmented cells in a bloom is enormous, and measured in the hundreds of thousands to billions of cells per liter (1 liter is almost a quart) depending on the species.

Blooms can be quite localized and appear as a streak on the water or can be very large and visible from space, such as the algal blooms that occur from time to time in Lake Erie and measure tens to hundreds of miles in extent.  The recent blue-green algal bloom in Lake Okeechobee was reported to be more than 30 square miles in extent.

What causes blooms?

Blooms occur naturally when the water contains an excess of nutrients such as phosphorus and other compounds.  This causes an increase in the growth of algae leading to very high concentrations of cells that become visible as colored streaks and patches in the water.  Other factors involved in triggering algal blooms include temperature changes, sunlight intensity, changes in water chemistry and changes in water currents.

What are the red tides that occur in Florida?
A red tide is just another name for a bloom of “true” algae in marine water, and in this case a particular algal group called dinoflagellates.  Red tides can be red but more often occur as greenish or yellowish colored water in the coastal areas of Florida.  The term “harmful algal bloom” is often preferred in referring to these dinoflagellate blooms that do indeed harm wildlife and human life in different ways e.g. toxic shellfish poisoning; respiratory illness; mass fish kills.

So what caused the blue-green algal blooms in Lake Okeechobee?

First, it is important to understand that blue green algae are uniquely different.  Not only are they photosynthetic bacteria but they are also capable of manufacturing their own supply of nitrates from nitrogen in the atmosphere, one of their crucial nutritional requirements.  So the blue-greens have plenty of nitrogen to live on but they also need other important elements and compounds to thrive.  One of these is phosphorus, which often occurs naturally in water in trace amounts as phosphates.  If phosphorus is scarce, then this limits the growth of the blue-greens even though they have potentially a lot of nitrates available.  The amount of phosphorus available becomes a limiting factor for growth of the blue-green algae.  If phosphorus becomes more abundant in the water, then the blue-green algae thrive and multiply until they become visible as a bloom.  It is believed that high phosphorus concentrations in Lake Okeechobee are capable of triggering blue-green algal blooms.

So where did the phosphorus come from in Lake Okeechobee?

Lake Okeechobee is surrounded by agricultural land that is being intensively farmed.  Run-off from the farmland appears to be entering Lake Okeechobee, and this includes various phosphate-rich fertilizers and herbicides such as Roundup (glyphosate).

But Lake Okeechobee water levels are higher than the surrounding plain.  How can run-off into the Lake happen?

Well, firstly, Lake Okeechobee and the surrounding farmland share a common water table.  Transfer of minerals and soluble organic compounds can occur through the groundwater.  But probably more importantly, until recently it was common farming practice to back pump excess run-off water from the agricultural land into Lake Okeechobee.  Almost certainly this had led to the accumulation of phosphorus and other nutrients in the Lake as well as unused agricultural chemicals.  Aerial transmission into the Lake from crop dusting is also possible.

So now that back pumping has been discontinued will this solve the problem?

Not really, because although farmers now are not allowed to back pump into the Lake, the South Florida Water Management District has responsibility to alleviate the threat of flooding.  They can – and do – back pump surface water from the surrounding land into Lake Okeechobee, if excessive rainfall conditions threaten to flood the communities around the Lake.  Rainwater running off the agricultural land will still contain phosphorus and other compounds derived from fertilizers.  Furthermore, from time to time the Army Corps of Engineers controls the level of Lake Okeechobee by releases of lake water into the canals, which in turn feed into the estuaries around Stuart and other coastal communities.

Are there any other agricultural products that are contributing to the appearance of blue-green algal blooms?

Yes, there is one in particular that is of great concern.  Glyphosate is the active ingredient in the well-known weed killer Roundup.  It is used intensively by farmers over much of North America.  South Florida is one of the areas where it is being used very heavily in agriculture, and has been since at least 1992 (the earliest available data).  A little further to the north, Central Florida’s usage of glyphosate surged in 1993 and continued until 2013 (the last available data) and may also be a source of glyphosate in Lake Okeechobee but originating further upstream in the Kissimmee River watershed and its interconnected lakes.

http://water.usgs.gov/nawqa/pnsp/usage/maps/show_map.php?year=2001&map=GLYPHOSATE&hilo=L

Why is glyphosate of such concern?

Glyphosate is an organic compound with phosphorus as an important component as well as nitrogen in its chemical make-up. It was invented by Monsanto chemists, brought to market in 1974, and its chemical name is N-(phosphonomethyl)glycine (aka 2-[(phosphonomethyl)amino]acetic acid)  –  glyphosate for short and much more easily remembered.  Monsanto’s patent on glyphosate expired in 2000 and since then it has been manufactured by dozens of companies with a significant drop in price and therefore increasing popularity with farmers.  In 2007 it became the most-used herbicide in agriculture in USA.  It works as a weed killer by inhibiting the production of certain plant amino acids and enzymes.  After it has done its deadly work, some of it can break down in the soil into simpler molecules of carbon, hydrogen, oxygen, nitrogen and phosphorus.  Excess glyphosate can run off into water, particularly at peak farming times.  Its use has been expanding in the agricultural sector by about 20% per year for the last several years.

So far, so good.  It kills most green plants, if that is what you want.  I personally use it to kill poison ivy on my property.  Unfortunately, it has become apparent through a number of recent laboratory-based studies that glyphosate does not act as a killer for some blue-green algae, aka cyanobacteria.  Firstly, the blue-greens love the phosphorus in glyphosate or its degradation products, which otherwise is a limiting factor in their survival.  They thrive on increased phosphorus.  Secondly and more insidiously, recent research has indicated that glyphosate actually enhances the growth of blue-greens.  The blue-greens apparently have the ability to absorb glyphosate directly from the water and some are tolerant to it or become adapted to it by rare genetic mutations.

OK, but rare genetic mutations are just that – rare!  So what?

Well, you remember that blue-greens are actually bacteria, not true algae.  As such their genetic material is distributed throughout the cell, and they reproduce by binary fission producing endless clones.  There is no “mix-and-matching” of chromosomes and genes such as occur in nucleated organisms using sexual reproduction that tends to dissipate the effects of mutant genes.  Once a cyanobacterium has undergone a mutation, that mutant gene is replicated again and again as the cell divides.  It produces clones of the mutant cell, and if that mutant has an advantage (such as resistance to or affinity for glyphosate), it will rapidly spread.

A more familiar example is the recent rise to prominence of so-called superbugs that are resistant to antibiotics.  Human infections are often related to bacteria that enter the body, and are treated by the intake of prescribed antibiotics as a course of treatment for a number of days.  If the antibiotics are not taken for an adequate period of time, the residual bacterial population includes mutants that resist the drug in question, and in turn that drug becomes less and less effective against new infections. This way a superbug is created e.g. MRSA (methicillin-resistant Staphylococcus aureus).  So think of the blue-greens as bacteria (which they are) and glyphosate as an antibiotic (which it is).  Those blue-green cyanobacteria that survive the glyphosate thrive as mutants and have the capacity to spread widely.

Do blue-green blooms last forever?

No.  Eventually the blue-green bloom uses up available resources and requires more nutrients than are available leading to a decline in the number of cells in the water column.  Also in temperate climates, the onset of winter temperatures can put an end to algal blooming for that season.

Then what happens?

The blue-green cells die off and sink to the bottom of the lake or estuary.  Other bacteria move in and use the debris from the dead blue-greens as a source of carbon, and use oxygen in the water to fuel their own growth.  This in turn leads to oxygen depletion that can be very severe.  Without oxygen in the water, normal aquatic life becomes impossible and a dead zone is created: fish move away, and other organisms die that can’t move into more oxygen-rich environments.

How many blue-green algae/cyanobacteria exist?

About 2500 living species have been described in the literature but probably double or treble that number exist and await discovery and description.  They have a very long geological history.  Fossilized blue-greens have been discovered in rocks 3.5 billion years old.

How many are harmful?

Only a dozen or so species are actually harmful when they form blue-green blooms and emit toxic substances.  In the recent outbreak, Microcystis aeruginosa has been identified as a bloom-forming cyanobacterium together with a couple of others.

So which blue-greens are responsible for the Lake Okeechobee and St Lucie River blooms?

The Florida Dept of Environmental Protection (DEP) took a number of samples from sites in Martin County and adjacent areas from Late May to Late June 2016 and the results are available at their website:

Clearly, Microcystis appears to be important in several blooms, but quantitative and qualitative data are not provided for the majority of samples, making further evaluation impossible at this time. Dolichospermum (aka Anabaena) is a well known blue-green that produces nerve toxins and liver-damaging toxins, as does Microcystis. Planktolyngbya limnetica is another well known toxic blue-green.

How adequate has the sampling and analysis program by DEP been?

It is difficult to say for sure, since DEP only provides results of their program, not the sampling and analytical strategies themselves.  However, from what can be gleaned from their website it would seem that during the month of June 2016 DEP collected 24 samples from 7 counties (Martin, Palm Beach, St Lucie, Lee, Charlotte, Hendry, Glades) over a 29 day period, covering a transect from the Atlantic coast to the Gulf of Mexico (Stuart/Palm Beach to Fort Myers).  Of those 24 samples, 83% were reported “mixed algae; no dominant species in the sample” without further details.  I would judge this to be a token response to what is clearly a major emergency.  The analytical results appear to be lackluster to judge from details available on the website.  No doubt DEP activities are constrained by their budget, but the lack of urgency in attempting to characterize these blooms is disappointing at best and may eventually be judged negligent to some degree.

What is known about Microcystis aeruginosa?

Quite a lot.  It is the most common harmful algal bloom-forming species in freshwater.  The cells are tiny but colonies can be macroscopic in size and contain gas vesicles that allow the colonies to be buoyant and float to the surface of the lake.  It produces both neurotoxins and hepatotoxins that contaminate the water and have been known to kill  dogs, other large animals and livestock in general that drink the polluted water.  The toxins may be carcinogenic.   Microcystis has a drastic effect on dissolved oxygen in the water that can lead to mass fish kills.

Can blue-green algae live in salt water?

This depends on the species.  Many truly marine blue-greens are known in seas and oceans where they play an important role in nitrogen fixation and are important components of the marine ecosystem.  In the case of Stuart and the St Lucie inlet and estuary, these natural estuarine waters have been diluted and/or replaced by fresher water discharges from Lake Okeechobee as shown in recent Florida Oceanographic Society water quality reports:

http://www.floridaocean.org/uploads/docs/blocks/867/160630.pdf

In turn this has allowed freshwater blue-greens such as Microcystis to establish colonies and blooms in areas that otherwise would support more saline organisms.  So, for example, on June 30th 2016, the north and south forks of the St Lucie River, the St lucie River adjacent to Sewells Point, and the Manatee Pocket were reporting salinity values in the range of zero to 13 parts per thousand, areas which otherwise would be in the range of 15 to 30 parts per thousand.  Hence some of these diluted saline waters can now support freshwater blue-greens.

Alarmingly, recent laboratory-based research has shown that some blue-greens – such as Microcystis – can build up resistance to increased salinity and, therefore, if this happens in the natural habitat can expand their range from freshwater to higher salinities.

What can be done to improve the situation?

If you have a vote at any level of government, contact your elected politicians to highlight the urgent nature of the blue-green blooms and to bring pressure to bear to use available resources to solve the matter.

  • Stop the back pumping of run-off water by anyone into Lake Okeechobee.
  • Curtail the heavy application of phosphorus-rich agricultural chemicals in farmland surrounding Lake Okeechobee.
  • In particular, request a thorough scientific investigation into the effects of glyphosate (Roundup) on blue-green algae (cyanobacteria) and their blooms.
  • In the long run, demand that the dike surrounding Lake Okeechobee be rebuilt with a view to diverting southwards the impounded waters back into the Everglades.

Regarding Senate Bill 10, and the recent changes made to the bill~

I thought I would just go on-line and compare the first bill to the second with its amendments…kind of like juxtaposing town ordinances between first and second reading. Well, I learned over the past week, that this is not as easy as I had anticipated. In fact, to interpret well, I think I need a lawyer, or to become one.

Nonetheless, today I have gathered information to help us understand what is/has happened with Senate Bill 10. The essence of its changes is encapsulated in these recent words by Senate President Joe Negron about the bill:

“Harmful discharges from Lake Okeechobee have flooded communities on the St. Lucie and Caloosahatchee Rivers with massive amounts of toxic algae that destroyed estuaries and harmed the local and state economies. Unfortunately, incidences like these are not unique in our state and are a symptom of the lack of attention to water resource development. The lost summer must be a wakeup call for all Floridians.

Powerful words from a Senate President. And between the lines we see that he is trying to build bridges to garner more support…as the powers that be have been repeatedly clubbing the bill over the head, in form with their outdated ideology.

So the bill has changed, it may be slightly wounded but it is still alive, and the dramatic destruction of our St Lucie/Indian River Lagoon has become the seed of change for our entire state. Wow. This is fitting as Martin County has a history of inspiring change and being  a leader when it comes to the environment.

Ernest Lyons, the great “Stuart News” newspaper man, and others are in their graves smiling I am sure. He may even be smoking a cigar.

Nonetheless, we must remain the epicenter of this state-wide change…we must keep foucs.

The toxic destruction from Lake Okeechobee is a not by accident, but a rather a state and federally sponsored decision embedded in a power culture that has ruled for over one-hundred years. It is time to crack this wide open, thus even though the bill is morphing Senate Bill 10 must keep the EAA land purchase and reservoir component.

And although it has grown to include others, it still has this critical component.

Concerns?

The Florida Wildlife Federation states:

“Unfortunately SB10 has been substantially amended to include funding for water supply developments (pipes and pumps)…The bill changes the direction of the state’s major land acquisition programs from conservation purposes, to acquisition and improvements to land and water areas to protect, restore, and DEVELOP, water resources…These amendments are concerning…” I trust FWF’s concerns are warranted and should be looked at.

Now for the fun part! Below you can compare the two bills, it has gone from 14 to 27 pages!

The press releases following help interpret the bill’s intent. Below the Florida Senate links are two reporter’s insights that I feel are quite helpful, Isadora Rangel of TCPalm and Nancy Smith from Sunshine State News.

In closing, we must never give up because we are destined to change the long-standing culture of drainage and destruction for the St Lucie River/ Indian River Lagoon and now for the great state of Florida.

SUMMARY OF CHANGES TO SENATE BILL 10

TCPALM, Isadora Rangel

MORE PROJECTS ADDED
Bradley also added projects to garner support from lawmakers across the state. Those include:
• Creating a loan program to help government and private entities pay for water storage projects that prevent it “from being discharged to tide or otherwise lost to protect the waters of the state.” The loan would pay up to 75 percent of the project and give priority to alternative water supply in areas with limited water sources or that are threatened by salt water intrusion.
• $20 million for grants to help local governments convert septic tanks to sewer systems or remove muck in the Indian River Lagoon and the St. Lucie and Caloosahtachee rivers, as Gov. Rick Scott has proposed;
• $35 million per year for the restoration of the St. Johns River and its tributaries or the Keystone Heights Lake Region;
• $2 million annually for septic-to-sewer conversions, stormwater projects, muck removal and other water quality projects in the Florida Keys.

Sunshine State News, Nancy Smith
The Coast-to-Coast Comprehensive Water Resource Program includes the following:

— Acceleration of the timing and funding for the state share of the Everglades Agricultural Area Storage Reservoir Project. The bill authorizes the purchase of land for the project from willing sellers in the EAA and does not authorize the use of eminent domain.

— Funding of the state share of all existing Comprehensive Everglades Restoration Plan (CERP) projects in the integrated delivery schedule (IDS), including the Lake Okeechobee Watershed Project, the C-43 West Basin Storage Reservoir Project, the C-44 Reservoir Project, the Western Everglades Restoration Project, the C-111 South-Dade Project, and the Picayune Strand Restoration Project.

— Direction to the Army Corps of Engineers to begin the reevaluation of the Lake Okeechobee Regulation Schedule to take into account repairs to the dike and new southern storage features to increase storage in the lake as early as possible.

— A new bonding program, building on the Florida Forever model that recognizes the need to bond for water resource protection and development across Florida. The bill transfers the remaining $3.3 billion of existing bonding authority from Florida Forever to the Florida Coast-to Coast Water Resources Initiative. The bill does not create additional bonding capacity.

— A new revolving loan financing program and statutory tools to allow the state, water management districts and local governments, to develop and operate water storage and supply facilities to service regional populations addressing the growing need for water supply in the state.

— Dedicated LATF funding to expand Legacy Florida to include projects addressing water quality and restoration with the St. John’s River and the Florida Keys.

— Funding to aggressively address the retrofitting or conversion to central sewer systems of outdated septic systems consistent with Gov. Rick Scott’s leadership on this issue.

— Provisions that encourage reuse by establishing a water reuse grant program, specifically to assist wastewater treatment facilities to expand capacity to make reclaimed water available for reuse.

The Martin County Difference, A Coastal Flight Comparison to “South Florida,” SLR/IRL

 

IMG_3180
St Lucie River/Indian River Lagoon, Martin County, FL (JTL)

Port of Miami, Biscayne Bay, Miami, FL (JTL)

Today my husband, Ed, is going to take you on a flight south along the Atlantic Coast from the St Lucie River/Indian River Lagoon in Martin County, to the Port of Miami. As we know, the coastline becomes more and more developed as one flies further south. Bright blue skylines of houses and condos morph into shadowy silver skyscrapers, and cargo ships. Expansive greenery slowly disappears…

I, probably like you, know people who grew up in Miami, Ft. Lauderdale, or Palm Beach County who have moved to Martin County to get away from the over-development and traffic nightmare of “down south.” Many tell stories about things changing “overnight,” and no longer recognizing the place they called home.

The “Martin County Difference,” its slow development, is not by accident. Many throughout the years have fought to keep our area less traversed than the rest of South Florida. One thing is for sure, if you want to keep it, you have to fight for it, or otherwise it will be going, going, GONE…

Ed’s tour-view, from the air, really makes the comparison hit home.

(Please see map of cities passed in flight, and 28 photos or slide show below.)

The Dramatic Shifting Sands of Ft Lauderdale, SLR/IRL

FullSizeRender 4
Comparison of 1883 historic map and Google Earth image 2017, Ft Lauderdale’s New River Inlet

Today I am sharing two creations of my brother, Todd Thurlow. Entitled “Ft Lauderdale House of Refuge/Life Saving Station,” and “Short Version,”they were originally for my mother, Sandra Henderson Thurlow and Timothy Dring’s “Image of America, U.S. Life Savings Service” book presentation at the Elliott Museum.

For me, Todd’s videos are mind-boggling as they bear witness to how much and how fast we humans can change the  environment. Like an army of ants, we organize; we build; we destroy; we create…

By comparing and contrasting Google Earth maps of today with historic maps from 1883, 1887, and 1935, Todd’s “time capsule flight,” takes us through time and space to see the shifting sands of the multiple New River Inlets; Lake Mabel that morphed into Port Everglades; remnants of the forgotten Middle River that spread and contracted into new canals and developments; and of course, for mom, House of Refuge #4, that once rested north of a New River Inlet that today we can see is completely filled in, while beach-goers relax in reclining chairs like nothing ever happened!

Maybe one day we humans can use all this energy and ability to really fix our waters that have been destroyed during all this construction? Wouldn’t that be a dramatic video?

In closing, in the early 1900s, the New River… that was believed by the Seminoles to once be an underground river that collapsed and the Great Spirit revealed during an earthquake… was selected by modern-day humans as the “natural channel” to connect two of the largest drainage canals from Lake Okeechobee to the Atlantic Coast, the North New River/South New River, and the Miami.

Please watch and enjoy Todd’s videos below!

Don’t Kill the Albatross, Florida Legislature 2017, SLR/IRL

pUQi61488893495

mariner_shot.jpg
The Albatross from the Rhyme of the Ancient Mariner, Samuel Taylor Coleridge 1772-1834.

Today the Florida Legislature convenes for year 2017.  As we look down from the Heavens upon our great state what do we see? Mostly water… And yet water is such a problem for us. As the third largest state in the nation, and for the children of the future, it is imperative that we get this water problem straightened out….starting with the St Lucie River and the destructive discharges from Lake Okeechobee.

Because of Senate President Joe Negron,  I am very hopeful. Let’s just hope the state legislature doesn’t kill the albatross. The albatross? Let us remember the story of the albatross.

Remember 8th grade? Remember reading Samuel Taylor Coleridge’s poem the “Rhyme of the Ancient Mariner?” You may at least recall these lines:

Water, water, every where,
And all the boards did shrink;
Water, water, every where,
Nor any drop to drink.

The very deep did rot: O Christ!
That ever this should be!
Yea, slimy things did crawl with legs
Upon the slimy sea.

About, about, in reel and rout
The death-fires danced at night;
The water, like a witch’s oils,
Burnt green, and blue and white…

IMG_0725.JPG
St Lucie River 2016 toxic algae bloom, JTL

In case you have forgotten, in this famous poem, the Mariner is punished by the crew for killing the albatross with no good reason, a sign of good luck and of hope, and thus bringing devastation upon all.

We the citizens have been in a sea of frustration and thirst with “no wind” for years; we have watched our water as before the tortured Mariner turn blue and green and white. But hark, the  wind is blowing; the albatross is flying over… we have hope – a sign.

How shall the state legislature react? My hope is that they recall the lesson of the “Rhyme of the Ancient Mariner,” and remember, to whom they answer, and from whom they derive their power.

Water, water, everywhere…

Negron, ACOE, Inflicted Harm is not Safety, SLR/IRL

img_1521-version-3
Senator Negron 2014, JTL

President Negron’s recent press release about his visit to Washington DC to discuss Lake Okeechobee discharges is below as addressed to the Florida Senate. It pleases me to see that his words are in keeping with his first op-ed on the issue published in TCPalm on October 17, 2012. Some people don’t realize how long Senator Negron has been working on this.

In 2012 Senator Negron wrote:

“While the Corps claims that public safely is its top priority, it ignores calamitous results actually inflicted on the St Lucie Estuary. Its erroneous logic goes something like this: in order to avoid possible harm, we will inflict certain harm. The Army Corps is killing our oyster beds and sea grasses, while turning the St Lucie River into a grotesque brown cesspool unfit for swimming or fishing…”

MEMORANDUM: UPDATE REGARDING LAKE OKEECHOBEE DISCHARGES
TO: All Senators

FROM: Joe Negron, President

Florida Senate: http://www.flsenate.gov/Media/PressReleases/Show/2658

On Monday and Tuesday of this week, I had the opportunity to meet in Washington with Senator Rubio, Senator Nelson, Members of Congress, senior budget staff, and high-level representatives of the Army Corps of Engineers to discuss the best way to reduce and ultimately eliminate the devastating discharges from Lake Okeechobee. After completing these meetings and reviewing related documents, here are five things I know:

1. If Florida advances funds to complete the rehabilitation of the Herbert Hoover Dike around Lake Okeechobee, the federal government will not repay the money to Florida. We will have simply spent hundreds of millions of dollars of General Revenue funds on what is unquestionably a federal responsibility.

2. As I have consistently advocated from day one, Florida’s best scientists should determine the Lake Okeechobee Release Schedule (LORS) and not the Army Corps of Engineers. Achieving this goal would take an act of Congress, a highly unlikely outcome.

3. Once the Herbert Hoover Dike rehabilitation is complete in 2024, the Army Corps of Engineers is not committed to storing one more gallon of water in Lake Okeechobee. The LORS must go through a multi-year review process, with the Corps predicting only negligible modifications to the release schedule. The Corps wants to avoid expected negative impacts it believes would result if the Lake is managed at higher levels than the present.

4. Under both the Comprehensive Everglades Restoration Plan (CERP) and the Central Everglades Planning Project (CEPP), redirecting damaging Lake Okeechobee discharges southward to improve the flow, timing, and distribution of water through the Everglades has already been authorized. The issue is not if we will have additional southern storage, it is when and where.

5. If the Florida Legislature approves and funds additional water storage south of Lake Okeechobee, the Army Corps of Engineers will reevaluate the order of priority in the 2016 Integrated Delivery Schedule (IDS). Florida is a partner in Everglades restoration and its decisions influence and impact federal participation in the 50-50 matching program. An example of this reality is the Corps’ recent initiation of the Lake Okeechobee Watershed one year earlier than planned after adverse discharge events.

I look forward to discussing this important issue further when we reconvene in Tallahassee next week.
