Opinion: Collaborate over good policy

By Steve Urie

In a recent op-ed released to regional news services (Lake Tahoe News, Nov. 20), Tahoe Regional Planning Agency Executive Director Joanne Marchetta wrote: “TRPA is taking partnership to the next level and is making ‘epic collaboration’ its central strategic goal.” She went on to say that the Compact between California and Nevada that created TRPA was to “harmonize the needs of the region as a whole so as to ensure equilibrium between the region’s natural endowment and its man-made environment.”

That may have been the intent, but it hasn’t been — nor will be — the reality. When TRPA was formed in 1969, on the Nevada side of the border a race was under way to see who could build the largest and gaudiest casino, and on the California side developers had already converted Tahoe’s most important wetlands into a 1,500-homesite marina community. Whether by shrewd planning or blind luck, in constructing TRPA the states agreed to a 15-member board of governors with seven voting members from each state and the 15th to be a non-voting federal appointee. Gridlock was assured, all development ceased, and the basin’s environment was spared further mass destruction.

The constant policy tug-of-war between developers, environmentalists, and agencies from two states and six local governments guarantees that only the very wealthy and very patient can afford to navigate Tahoe’s development process. And as a result, mercifully the basin’s land-use is locked in the 1970s. Contrary to Marchetta’s lofty goal, since its inception TRPA has been spectacularly unsuccessful in creating collaboration, much less harmony, between developers, environmentalists, and the Basin’s residents and three million annual visitors.

Even the two state legislatures that created TRPA are in constant conflict over Tahoe’s land-use and development policies. Less than two years ago, TRPA was precariously close to being shut down because there was no collaboration between Nevada and California. Seven times since 1975, Nevada has threatened to withdraw from TRPA when they believed the agency was unaccommodating to their needs. Only because California Gov. Jerry Brown understands that the bureaucratic standoff overseen by the TRPA Board of Governors assures that a 1960’s-style development free-for-all doesn’t return to the basin does TRPA still exist. At Lake Tahoe, it’s not collaboration that maintains environmental equilibrium, but contentious ongoing policy gridlock.

But that’s not to say that there is no collaboration at Lake Tahoe. Since 1997 when President Bill Clinton promised federal money “to protect Lake Tahoe’s environment, and with it the area’s economy and quality of life,” there has been epic collaboration between the more than 50 agencies, universities, and organizations that have cozied up with TRPA to share in the more than $100 million that has annually flowed to environmental programs managed by the federal agency.

That kind of serious money attracts those whose paychecks are underwritten by the public like pigs to slop and has bought major collaboration from the basin’s public service employees. But that money is drying up, and with Congress as contentiously gridlocked as the TRPA Board of Governors, the prospects of California Sen. Dianne Feinstein’s $415 million Lake Tahoe Restoration Act passing and replenishing TRPA’s environmental coffers continues to dim.

Of the $1.7 billion spent on environmental projects, more than $100 million has gone toward environmental research, monitoring, and technical assistance. One of the research and environmental program centerpieces implemented on Marchetta’s watch is the Asian clam control program. In her op-ed, she says of it: “At iconic Emerald Bay, divers are removing five acres of rubber mats that were laid down to control an infestation of harmful invasive Asian clams. The collaborative project not only reduces the population of non-native clams, but also studies the mats’ effectiveness as a way to control other invasive species populations in the lake.”

That summary of the multi-million-dollar program by the head of the agency responsible for scientific and fiscal oversight of the program is stunningly uninformed, self-serving, and naïvely wrong. By all measurements, the Asian clam control program was a disaster, and TRPA staff says that it’s probable that the 35 tons of rubber mats that covered Emerald Bay are currently being put into storage and will never be taken out.

Two years ago amid much media hype when the mats were rolled out, Tahoe Environmental Research Center Director Geoffrey Schladow said that the project was “already a scientific success.” Since then Schladow and three other researchers concluded in an obscure $264,000 Forest Service study that “it is difficult to understand the efficacy of a large scale [clam] treatment program. [And] a hypothetical 100-acre area for [clam] treatment indicates that total costs of treatment can range [up] to $26 million.” That’s a lot of money to kill tiny mollusks that cause no harm.

Yet at this summer’s Tahoe Summit, Schladow glossed over the project’s failures and boasted to the politicians and environmental stewards that 90 percent of the clams under the mats had been killed. He neglected to tell the 400 dignitaries and contributors that at least a dozen native species had been decimated along with the non-native clams, and that the clams would repopulate Emerald Bay in about the same time as it took to suffocate most of them.

Even though by all observations and measurements the $900,000 Emerald Bay project to “control” the benign clams was a complete disaster, in a thinly veiled appeal for more funding, Schladow recently said that whether Asian clams should be suffocated under rubber mats in the future is now “a community decision of do we want to try to control these [clams] at a cost, or throw up our hands and say, ‘that’s it.’”

It’s not only gratuitous but irresponsible for one of the basin’s leading environmental researchers to toss his failures back to the community and imply that because he didn’t receive enough money to continue his program, it’s not his fault if a project fails, but the community’s — an accusation sure to foster harmonious collaboration between the public and the scientific community. (Two years ago, Schladow started referring all attempts at technical collaboration from this correspondent to TRPA.)

The plan to eradicate Asian clams may be the most ecologically destructive invasive species control plan ever employed — and it not only didn’t work, but destroyed many times the number of Tahoe’s native aquatic animals as it did non-native clams. Yet, Marchetta points to it as a model project that underscores the value of TRPA’s Environmental Improvement Program.

TRPA is charged with oversight of the basin’s invasive species programs, and the report to the Forest Service says that all data was given to the Lake Tahoe Asian Clam Working Group. When asked who the working group members were and what was reported in their minutes. TRPA’s public information officer wrote: “No minutes are kept as this is an informal working group. We generally keep minutes for meetings where policy decisions are made. The meetings are open to all stakeholders. Each interested organization is represented by appropriate staff members, and there is no selection process for which organizations attend.”

If millions are spent to carpet the bottom of one of the world’s scenic wonders with rubber matting is not a policy decision, the public is not considered a Tahoe stakeholder, and environmental programs are determined by an informal group of various agencies’ staff at unpublished meetings, it’s concerning what other informal decisions TRPA is making.

And if TRPA and their scientific partners are going to blame environmental failures on a lack of funding and invoke the community’s best interests when launching new programs, it only seems equitable that the community be allowed to participate in the environmental decisions of how their money is spent.

TRPA wasn’t formed to create collaborations. Its charter is straightforwardly simple: the agency is to protect and restore the Tahoe basin’s environment for all. And hopefully, Marchetta’s plans for epic collaboration include the public in those decisions that most affect them and their environment.

In a September op-ed Marchetta said, “Tahoe is standing on a fiscal cliff and the ground is sloughing off beneath our feet. Staring straight into an impending breakdown in funding, we are seeking another breakthrough. To that end, we are bringing our best creative thinking, our greatest drives toward innovation, our entrepreneurial spirit, and our strongest collaborative skills to imagining new funding sources, new collaborations and partnerships.”

Harmonious collaboration would certainly make TRPA Executive Director Marchetta’s job much easier, and it doesn’t take much imaginative thinking or creative entrepreneurial skill to understand that the best way to get public support is to allow their participation, listen to their wants, spend their money wisely, and collaboration will then follow.

    The example in this article leaves a lot of information out that might make it more worth paying attention to, especially for those of us who are not marine biologists. So in the end I have no idea if it has any valid points.

    For example, I’ve heard for years about the peril of Asian clams to Tahoe. The author essentially says they’re harmless. To be more convincing, I’d like to know:

    -Why did the project originators claim that these clams were so harmful? What was the reason given that it was so important to eradicate them?

    -Why does the author make the claim that they’re harmless? Proof?

    -What other species were killed by the mats? How many? How important are they to the lake? How does this balance against eradicating the clams?

    -Why does he say that the clams will certainly come back? Where – just in Emerald Bay, or all over the lake? What is the evidence for this?

    -He says the project was a complete disaster, but why? How does he define this, and where is the proof that it was a disaster?

    -To what extent should the non-scientific public be involved in this type of decision making, and why should this involvement be as intensive as in things like land use decisions that may impact them more directly and for which they may bring more than just a layman’s knowledge to the discussion?

    This article brought up some points of which I wasn’t aware, but the example given and logic used were less than convincing. While I think the point was to rail against imperial behavior by TRPA and call for more public involvement in general, the example used seemed ineffective to me. I have no particular involvement in this asian clam example, but am a bit puzzled by this opinion piece.

    I would ask that you read Steve Urie’s opinion piece, very informative. Yes, Not born on the Bayou, there is some information lacking, but it is worth a read.

    Not Born on the Bayou, excellent questions and it would be terrific if the TRPA had one critical thinker who thought as deeply about the science behind their Asian clam program as your observations show you have. You are absolutely correct that Asian clams have been maligned for years – and a few years ago, I asked why and did some research.

    It started in 2008, when a plausible reason was needed to explain how Tahoe’s dissolved calcium could rise from its average nearshore level of 9.2 parts per million to 12 ppm — the minimum calcium concentration needed for quagga and zebra mussels to propagate. Sierra lakes are in the lowest 2% of all U.S. lakes for dissolved calcium, and are unable to support quagga mussels. That year UNR professor Sudeep Chandra wrote that Asian clam shells create high-calcium microzones where quagga can survive.

    They don’t – Asian clams actually decrease dissolved calcium by absorbing it from the water to build their shells – but Chandra has received hundreds of thousands of dollars over the last six years to try to demonstrate that quagga can survive 90 days in calcium-rich microzones, such as the Tahoe Keys. In his last annual report to the Forest Service, he wrote that 19 of 20 of the adult quagga he was testing died between day 8 and day 20. He reported that he would try again.

    Chandra and TRPA also say that Asian clam fecal matter causes algae blooms. Like all clams and mussels, Asian clams live on algae and detritus they filter from the water — they actually improve water quality. This was acknowledged two years ago in a $312,000 study that was given to the mysterious LT Asian Clam Working Group.

    Finally, the dozen species that were killed along with the Asian clams are all native to Lake Tahoe, and I would judge that killing one non-native species that causes no harm balances highly unfavorably against killing a dozen native species. The $264,000 study given to the LTAC Working Group says that Asian clams repopulate to pre-treatment levels in 22 months. The links to these and other reports can be found on “The Science” page at SaveTessie.org.

    And yes, until TRPA demonstrates one negative thing Asian clams do or provides a single scientific justification for killing Asian clams, I’ll stand by my claim that the eradication program was a complete disaster. The point of my piece was not to rail against TRPA’s imperial behavior, but to illustrate how they have wandered from their mission, which is to preserve and protect the Basin’s environment.

    You are correct that wasting money on the Aquatic Invasive Species program is relatively minor compared to things like land use decisions and forest and watershed management. But TRPA has demonstrated less than a layman’s knowledge on the AIS discussion. And the Asian clam program is but one current example of how they “imperially” (nice choice of words) ignore proven science to sometimes buy support of other agencies and organizations by doling out slices of their annual $100 million public allowance for environmental improvement.

    As you point out, the aquatic invasive species program is difficult to understand and evaluate. And because of that, TRPA can say and do just about anything they want if they claim a species will harm the lake, and no one questions them. My purpose in writing Tessie, Quagga Mussels, and other Lake Tahoe myths was to present the science behind TRPA’s AIS program, and to have TRPA perform a risk assessment by independent experts, who don’t receive an annual slice of the TRPA Environmental Improvement Plan pie.

    Where to start….

    Direct me to the part of the paper that supports this statement:
    “They don’t – Asian clams actually decrease dissolved calcium by absorbing it from the water to build their shells”

    Did you leave anything out?

  5. Steve Urie says - Posted: November 29, 2014

    cosa pescado, I didn’t say that either of the studies I reference in my reply say that Asian clams decrease dissolved calcium, but intuitively you can probably deduce that they do. In any closed system, such as a lake, dissolved minerals are only increased by further leaching of a mineral from sediment deposits. The primary source of natural dissolved calcium is from limestone (calcium carbonate), and the Sierra Nevada has remarkably low limestone deposits.

    Lake Tahoe was formed about 25 million years ago. You can safely assume the amount of calcium from natural deposits won’t measurably increase in your lifetime. But calcium that leaches from concrete can in fact measurably increase nearshore dissolved calcium. However it would take 11,800, 40-foot cargo containers of limestone to raise the calcium in Tahoe’s water to 12 ppm — the minimum amount needed to support quagga. That’s more limestone than is in the stretch of I80 from San Francisco to Chicago.

    Asian clam shells are about 40% calcium carbonate. That calcium comes from the water that they filter to feed. And although it’s a minuscule amount, Asian clams do indeed decrease dissolved calcium instead of increasing it as TRPA claims.

    “Asian clam shells are about 40% calcium carbonate. That calcium comes from the water that they filter to feed. And although it’s a minuscule amount, ***Asian clams do indeed decrease dissolved calcium instead of increasing it*** …”

    You are leaving out something very important.
    Intentionally, or not, something very big is missing.
    What is it.

    You did read the research papers, correct?

    ‘I would ask that you read Steve Urie’s opinion piece, very informative.’
    Stay tuned OLS.

  7. cosa pescado says - Posted: November 29, 2014

    I invite anyone to jump in and answer the question about what is being left out in the statement in question.

    The answer is very simple, you don’t need to read any research papers.

  8. cosa pescado says - Posted: December 3, 2014

    The answer is:. The shells of non living clams. It’s a simple mass balance. Corbicula take Ca out of the water column to grow their shells. And they need a lower concentration to get started. And because Ca is the limiting nutrient, they benefit from an increased concentration of Ca. Quagga/Zebra mussels do the same thing, but thrive under higher [Ca].
    You want us to look at it as just the living clams removing Ca from the water column and ignore the fact that dead clams don’t remove and Ca and as their shells decompose Ca returns to the water column. There isn’t a net loss of Ca from the water column because of the clams.
    Dead Corbicula concentrate Ca. In areas where dead shell concentration is higher, [Ca] is higher. And puts that area within the range needed for Q/Z mussels to establish.

    You completely failed to mention this even though it is clearly mentioned in the research and has been from the very beginning. It is really basic stuff. You left this information out for one of two reasons. You either don’t understand the basics of the science, or you intentionally left it out because that part of the science doesn’t support your agenda.
    Considering that you went through the effort to write a book, I think it is the latter.

    From you earlier
    “That year UNR professor Sudeep Chandra wrote that ***Asian clam shells*** create high-calcium microzones where quagga can survive.

    They don’t – Asian clams actually decrease dissolved calcium by absorbing it from the water to build their shells –”

    Look at what I highlighted with ***.
    Living Corbicula absorb calcium, yes. And the dead ones leave shells that release calcium.

    Baseline Ca is low for Tahoe, and many other lakes in the region.
    What is also telling about your understanding of science is that you mentioned limestone as a source of background Ca. It certainly is. If you had a basic understanding of geology you would know that the remnants of living organisms are responsible for the Ca in limestone.

    You are ignorant of, or intentionally leaving out, some very basic scientific concepts.
    And at the same time promoting your book, and you as the author, as being as a reliable source for evaluating science.

    I am not going to buy your book. And I don’t think anyone in search of scientific knowledge on this complicated topic should buy your book and expect to become better informed.

    Come on man. You talk about algal blooms and fecal matter. Fecal matter concentrates nitrates. And then say “Like all clams and mussels, Asian clams live on algae and detritus they filter from the water — they actually improve water quality. “.

    There is a much larger, and still basic, concept of how matter moves in biological systems and the chemical availability of limiting nutrients. I doubt you cover any of that in your book. Basic mass balance equations are discussed? Unlikely.

    And your web page starts off with “There is a greater chance of finding Tahoe Tessie than of quagga mussels or New Zealand mud snails infesting Lake Tahoe’s crystalline waters. ”

    And concludes with
    ” If you are undecided about the issues, read “The Science” or buy the book ”

    You put ‘the science’ in quotation marks for a reason, to cheapen it, employ sarcasm, etc.

    It would be appropriate to use “The Science” when talking about creationism because it is completely unscientific. The earth is 20,000 years old, according to “The Science” of the Creation Museum. That sentence is a valid use of “” to call out something as illegitimate.

    In conclusion, you fail to demonstrate that you understand enough basic scientific ideas that are needed to begin to discuses invertebrate biology, nutrient transport in biological systems, or anything related to the researchers you attempt to call out. Furthermore, why hide your analysis behind a paywall? If your goal is really to enhance information that leads to better decisions you could have published your work for free on the internet.

    You reek of disinformation and your ‘sciency’ rhetoric didn’t fool me for a second.

    Cosa Pescado, Thank you for the tutorial on Quagga/Zebra mussels. I read thru it twice!
    Now I’ve got clams on the brain and small mussels in my arms and legs. I’m a walking, talking Corbicula!
    Oh great angry sky man, don’t let me live out my senior years as a bivalve! Old Long Shell (OLS)

    You are welcome. And hilarious.
    Old humans need their Ca too, especially if they want to keep skiing.

    As expected, no response from the author.
    A lot of effort went into this disinformation piece. Does anyone know what they are really up to?
