“Environmentalism” has been hijacked by nativism

Our family contributed to several mainstream environmental organizations for decades.  We were Sierra Club members because we wanted clean water and clean air.  We were Audubon Society members because we care about birds and other wildlife.

About ten years ago, we learned that these organizations were actively participating in projects demanded by native plant advocates to destroy our non-native urban forest and fence the public out of its public parks in order to turn our parks into native plant museums.  When we learned about the huge quantities of pesticides used by these projects that was the last straw.

We spent several years trying to convince these organizations that they were making a mistake by supporting projects that are doing far more damage to the environment than any theoretical benefit of native plants.  Much of our effort was directed to the Sierra Club because they claim to be a democratically run organization.  After several years of futile attempts to change the policies of these organizations, we quit because we did not want to contribute to the damage they are doing to the environment.

The Nature Conservancy was the only environmental organization to which we were still contributing.  Below is our “resignation” letter to The Nature Conservancy, which explains why we finally gave up on them as well.  This was not an easy letter to write because we care deeply about the environment and the animals who live in it.  We believe that environmentalism has an extremely important role to play in society and we would like to participate in an organization that is focusing on the environmental issues of our time, particularly climate change.

Mark Tercek, Executive Director
The Nature Conservancy

Dear Mr. Tercek,

We have been contributors to The Nature Conservancy for decades.  In the past few years we increased our donations because of the publications of TNC’s former Chief Scientist, Peter Kareiva.

While other mainstream environmental organizations were actively supporting destructive and restrictive ecological “restorations,” Mr. Kareiva was questioning that conservation strategy.  In his publication, “What is Conservation Science?” Mr. Kareiva said, “Our vision of conservation science differs from earlier framings of conservation biology in large part because we believe that nature can prosper so long as people see conservation as something that sustains and enriches their own lives.  In summary, we are advocating conservation for people rather than from people.”  Mr. Kareiva was also articulating that revised mission for conservation in presentations around the country (which we attended), in TNC’s publications, and in mainstream media.

As you know, Kareiva’s viewpoint was in conflict with the old guard of conservation biologists who subscribe to the tenets of invasion biology.  This conflict resulted in a confrontation of the old guard against TNC that was reported by the New Yorker in 2014.   TNC resolved that conflict by making a commitment to quit publishing Mr. Kareiva’s viewpoint in mainstream media and by restoring eradication of “invasive” plants to its budget.  That agreement foretold Kareiva’s departure from TNC.  Not publishing is tantamount to career suicide for scientists.  Mr. Kareiva has left TNC, as any self-respecting scientist would who has been deprived of his freedom to publish.

While this battle between competing visions of conservation played out, the country’s foremost invasion biologist, Daniel Simberloff, conducted a survey of TNC project managers to determine what, if any, impact Kareiva’s leadership was having on TNC’s conservation strategies.  Most survey respondents (95%) reported that they “manage” non-native species and nearly all reported that they would devote more effort to that task if more resources were made available.  Project managers devote a “substantial proportion” of their resources to “managing” non-native species and they expressed skepticism about “academic research and the invasion management controversy in particular.”  Simberloff did not ask project managers what methods they are using and so we have no insight into the use of pesticides by TNC.  This is probably information that Simberloff would rather we not have. Invasion biologists prefer to ignore the destructive methods that are used in the fruitless attempt to eradicate non-native plants.

Ecological “restorations” are damaging the environment by destroying useful habitat, poisoning open spaces with pesticides, and killing animals perceived to be competitors of native animals.  These projects are usually futile because the plants and animals that are being eradicated are adapted to current environmental conditions that are not reversed by their elimination.  The “native” ranges of plants and animals must change in response to changes in the environment, most notably climate change.  So-called “invasive” species are symptoms of change, not causes of change.

Here in the San Francisco Bay Area, our urban forest is being destroyed because it is predominantly non-native.  Native plant advocates have fabricated an elaborate cover story to mask nativism because widespread destruction of plants and animals does not appeal to the public.  Our public lands and open spaces are being poisoned with pesticides to kill vegetation and prevent trees from resprouting after they are destroyed.  We are unwilling to support that agenda by contributing to organizations that engage in these projects.

Therefore, we will not renew our TNC membership and we will not contribute further to TNC.  If and when TNC abandons its attempts to eradicate plants and animals that are performing valuable ecological functions, we would gladly renew our contributions.

Sincerely,

[Former Members of The Nature Conservancy]

Climate Change vs. Biodiversity: NOT!!

A new study reported changing public and scientific interest in biodiversity compared to climate change.  Using reports in the media and scientific journals in the United Kingdom and the US, as well as funding of scientific studies by the World Bank and the National Science Foundation, the study reports that the interest in climate change has increased and the interest in biodiversity has decreased in the past 25 years.

This analytical approach seems to suggest that these two environmental issues are mutually exclusive, that the interest in one is at the expense of the other.  We find this both unfortunate and unnecessary because we consider these two issues intimately related.  Climate change is increasingly the biggest threat to biodiversityIf plants and animals are unable to adapt to climate change, they are doomed to extinction. 

Therefore, we believe that science should study these topics together.  In fact, the study on which we are reporting acknowledges the relationship between these topics:  “Dual-focus projects are being funded more often, but… ‘this is relatively small and does not mitigate the plateauing expenditure on biodiversity research.’” (1)

Conservation in a changed climate

As long as conservation and “restoration” projects are devoted to replicating historic landscapes, they are likely to be unsuccessful.  The climate, atmosphere, and soil conditions are no longer suited to a landscape that existed hundreds of years ago, particularly in urban environments.  Therefore, if biodiversity is to be preserved by conservation and restoration, such projects must look forward, not backwards. 

We have been watching the Nature Conservancy closely for signs that it is adapting to climate change.  We look to the Nature Conservancy to lead the way because they employ hundreds of scientists.  In contrast, many mainstream environmental organizations employ more lawyers than scientists.

We have reported that the Conservancy’s Chief Scientist, Peter Kareiva, is at least paying lip service to an approach to conservation that takes into consideration the profound changes in the environment caused by the activities of man.  This acknowledgement of the irreparably altered environment is encapsulated by the proposal to name a new geologic era, the Anthropocene.

Unfortunately, the old guard of conservation biology has engaged in a vigorous campaign to silence the Conservancy’s new approach.  This conflict between the old guard and scientists who have proposed a more realistic approach to conservation was recently reported by the New Yorker. (2)  According to that article, Peter Kareiva has made a commitment to the old guard to quit publishing anything regarding the Anthropocene and its implications for conservation practices.

The Nature Conservancy has responded to the article in the New Yorker in its on-line blog.  It doesn’t explicitly address the question of whether or not a commitment has been made to quit advocating for a more realistic approach to conservation.  However, it implies that the Conservancy plans to continue on a course of scientific innovation and experimentation, which it describes as “practical.”  Here is a specific choice made by the Conservancy that typifies this approach:

“We know it was worth spending millions of dollars to rid Santa Cruz Island of non-native pigs.  But we are pretty sure it would not be worth spending what could be hundreds of millions of dollars to rid California of non-native Eucalyptus trees (which also happen to harbor wildlife and monarch butterflies.)” (3)

Although the Nature Conservancy’s Chief Scientist may have agreed to “shut up,” we see signs of the Conservancy’s new approach in its latest magazine.  In a brief article entitled “Forests of the Future,” the magazine reports that they are no longer planting the species of trees that existed in the past in one of their properties in Minnesota, because they don’t believe that species is adapted to current or predicted future conditions.  Instead they are actively engaged in reforestation of the land with new species:

Over the past two springs, the team planted 88,000 tree seedlings across 2,000 acres in the northeastern corner of the state.  The seedlings consisted of species that should survive better in a warmer and drier climate—trees, such as red oak, found in higher numbers just south of the area. For a team accustomed to restoring forests to match historical landscapes, helping the North Woods [of Minnesota] adapt to a predicted future climate is a new but necessary idea.  [The Conservancy’s science director in Minnesota] says, ‘All of our modeling is saying the same thing,’ she adds, ‘We needed someone to actually go out and start trying some of this stuff.’” (4)

Looking forward not back

We are very encouraged by the Conservancy’s new approach and we hope that other land managers will be inspired by it.  We are also reminded of a recent visit to a nature reserve near San Luis Obispo managed by the local chapter of the Audubon Society.  We reported about this reserve in a recent article because the land managers had planned to destroy all eucalyptus trees on that property but were forced to scale back their plans in response to a noisy negative reaction from the public.

On our recent visit, we learned that this was a wise choice because many of the oak trees that were planted on this reserve by those who wish to “restore” it are quite dead despite the fact that the reserve has an extensive irrigation system.  These land managers looked back and the result of that retrospective thinking is a landscape of dead native trees.

Climate change requires land managers to wake up to the realities of what will grow where.  Land managers in the San Francisco Bay Area appear to be blind to that reality.  They repeatedly plant species where they grew hundreds of years ago and we are forced to watch the plants die repeatedly.

Peter Kareiva redefines conservation biology

Who is Peter Kareiva and why do we care about his definition of conservation biology?  Kareiva has been the Chief Scientist at the Nature Conservancy since 2002.  That’s a BIG job, given that the Conservancy employs about 600 scientists.  The huge number of scientists at the Conservancy is one of the reasons why it is unique amongst environmental organizations.  Most environmental organizations employ more lawyers than scientists.

The Nature Conservancy is the “leading conservation organization working around the world to protect ecologically important lands and waters for nature and people,” according to its website.  These measures of its scale are an indication that they aren’t exaggerating:

  • There are over one million members of the Nature Conservancy (of which our household is one).
  • They have protected more than 119 million acres of land, thousands of miles of rivers and created over 100 marine reserves worldwide.
  • They have projects in all 50 states of the US and 35 countries around the world.

The Conservancy restores as well as conserves

Another reason why we are interested in the opinions of Peter Kareiva is that the Nature Conservancy engages in some of the most aggressive restorations of which we are aware.  One of their famous projects is the return of tall grass prairie around Chicago, Illinois, which required the destruction of untold thousands of trees, many of which were native.  These projects began decades ago and have generated a great deal of conflict amongst those who value the trees and object to the methods used to kill them, including herbicides and prescribed burns.

Another famous Conservancy restoration is on the Channel Islands, off the coast of California.  Thousands of non-native animals were removed or killed.  Native mice were rounded up in order to carpet-bomb the islands with rodenticides to kill rats.  Feral pigs had been the preferred food of the Golden Eagle, which then turned to the rare Channel Island fox as a substitute when the feral pigs were exterminated.  So, the Golden Eagles were captured and shipped elsewhere.  Thanks to a captive breeding program the Channel Island fox was spared extinction.  Feral honeybees are also being exterminated because they are not native.  This is but a brief description of the extreme measures taken on the Channel Island to rid them of all traces of human habitation.

Peter Kareiva defines conservation goals

We were introduced to Peter Kareiva shortly after he joined the Conservancy, after a long career in academia.  In 2002, he was quoted in an article in the New York Times entitled, “As Alien Invaders Proliferate, Conservationists Change their Focus.”  As the title implies, this article reported on the emerging scientific consensus regarding ecological restorations:  “…a growing chorus of biologists is proposing a new approach to the fast-blending biosphere.  They also say change should be accepted as largely inevitable and choices for managing nature should be based on what is desirable and undesirable, not what is native and foreign.”  Peter Kareiva was one of the scientists supporting this new viewpoint:  “’Conservation biologists are too romantic,’ Dr. Kareiva said, ‘They think what’s good is what’s natural.  Let’s be serious.  A better vision is something that functions and has habitat quality and aesthetic quality.’” 

We have been following Kareiva’s career since that interview and he has become increasingly vocal in his opposition to out-dated notions of creating “pristine” historical landscapes.  He is now one of the proponents of naming the current geological era the Anthropocene in recognition of the reality of man’s pervasive impact on the environment.

In 2012, Kareiva and a co-author published a manifesto redefining conservation biology, which was defined by Michael Soulé in 1985. (1) As defined by Soulé, it was solely a biological science focused on biodiversity, and human influence was perceived as detrimental to its goals.  It was considered a “crisis science” which advocated for action in the absence of data because of the urgency of reversing environmental damage.

The world has changed significantly since 1985.  Human population has increased from 4.8 billion to more than 7 billion in 2011.  Energy consumption has also increased significantly as developing countries approach the standard of living of developed countries.   There is a growing understanding that human activities have altered even remote corners of the earth.  The preponderance of novel ecosystems has rendered irrelevant earlier notions of the importance of co-evolution in static ecosystems.  There is also waning political will to impose standards for conservation that are antithetical to the interests of humans.

Kareiva therefore proposes a new approach to conservation, which he calls conservation science.  It must be a multidisciplinary science which incorporates social science because it must accommodate both biodiversity and the needs of humans.  These are the core principles of conservation science:

  • ”First, ‘pristine nature’ untouched by human influences, does not exist.”
  • “Secondly, the fate of nature and that of people are deeply intertwined.  Human health and well-being depend on clean air, clean water, and an adequate supply of natural resources for food and shelter.”
  • “Third, nature can be surprisingly resilient.”
  • “Fourth…sustainable conservation can be achieved by empowering local people to make decisions for themselves.”

These are the values of an ecological philosophy to guide conservation actions:

  • “First, conservation must occur within human-altered landscapes.”
  • “Second, conservation will be a durable success only if people support conservation goals.”
  • ”Third, conservationists must work with corporations” because they “drive much of what happens to our lands and waters.”
  • “Fourth, only by seeking to jointly maximize conservation and economic objectives is conservation likely to succeed.”
  • “Finally, conservation must not infringe on human rights and must embrace the principles of fairness and gender equality.”

Kareiva concludes:

“Our vision of conservation science differs from earlier framings of conservation biology in large part because we believe that nature can prosper so long as people see conservation as something that sustains and enriches their own lives.  In summary, we are advocating conservation for people rather than from people.”

Bringing this message home

We hope that Kareiva’s viewpoint is driving the Nature Conservancy’s projects, but we don’t have enough detailed knowledge of those projects to know if this is the case.  However, we do know that the many “restoration” projects on our public lands in the San Francisco Bay Area do not conform to Kareiva’s standards because:

  • Local projects do not reflect the wishes of the community.  In most cases, the community was not even aware of the projects until they were completed.  When the public has had an opportunity to object to the projects, their objections are largely ignored.
  • Local projects use pesticides and many conduct prescribed burns.  These methods used to eradicate non-native plant species are harmful to the environment and the people and animals that live in it.
  • Local projects often exclude people by building fences around projects, closing trails, and restricting all recreational access to the trails.  Our local projects treat the public like intruders.

If the world’s largest conservation organization can redefine its goals to accommodate the needs of humans, what possible excuse do managers of our public lands have to ignore the public’s wishes?  The Nature Conservancy is responsible for lands acquired with the voluntary charitable contributions of its donors.  In contrast, the public owns our public lands and pays for the management of those public lands with our tax dollars.  Shouldn’t the managers of our public lands be more accountable to the public (who pay taxes whether they want to or not) than the Nature Conservancy is to its donors (who can choose not to donate)?

Cultural Lag: Public policy lags behind science regarding “invasion biology”

This is a good-news-bad-news story.  The good news is that the most successful environmental organization devoted to the preservation and conservation of wildlands, The Nature Conservancy, has announced its intention to reorder its priorities in what we hope will be a less destructive direction.  The Conservancy is a science-based environmental organization that is unique in that regard.  It employs over 600 scientists to guide and inform its projects, in contrast to many other organizations that employ more lawyers than scientists.  The scientific orientation of the Conservancy undoubtedly puts it in a position to reflect and respond to the increasingly loud voices of other scientists who are expressing concern about the costs and environmental damage that are the unintended consequences of the “restorations” which have evolved out of invasion biology.

The bad news is that public policy regarding native plant “restorations” lags far behind the developing scientific consensus regarding invasion biology, namely that original theories require revision.  This is the consequence of the cultural lag that is inevitable when science moves forward, but communication of its findings to the general public lags behind. 

The Nature Conservancy redefines its goals

In the past few months, the Chief Scientist of the Nature Conservancy, Peter Kareiva, has written several articles in the Conservancy’s publications expressing his views about the future of conservation.  In “Beyond Man vs Nature,”(1) Kareiva is quoted as saying that species preservation should not be the top priority of the Conservancy.  He admits he is “not a biodiversity guy.”  Rather, he says, “The ultimate goal [should] be better management of nature for human beings.”  He does not agree with those who claim that the earth is fragile and man must be excluded from nature in order to protect it.  He considers nature resilient.  He calls the concept of “biodiversity hot spots” sham science and he rejects the notion that conservation and development are mutually exclusive.  We wants conservation efforts to focus on the things that people need from nature such as clean water and clean air.  If and when people experience the benefits of conservation, they will support and participate in those efforts.  The Conservancy can’t save the world alone.  The active participation of the human population is required to achieve the Conservancy’s conservation goals.

In “Conservation should be a walk in the park, not just in the woods,”(2) Kareiva says that the Conservancy should participate in more urban conservation projects because that’s where most people live and even more will live in the future.  He wants conservation to be more visible to people and he wants people to benefit directly from the projects.

In his most recent publication, “Invasive Species:  Guilty until proven innocent?” Kareiva acknowledges the debate about invasive species.  On the one hand, a few invasive species have done a great deal of harm, particularly on islands.  On the other hand, many invasive species aren’t doing any harm and some are benefitting native species, even endangered species in some cases (e.g., Southwestern Willow Flycatcher in Tamarisk).  He concludes, “Science-based conservation cannot be about knee-jerk platitudes and simple views of good and evil…the fact is we cannot control all invasive species, and in many cases, yesterday’s invaders have become plants and animals that are beloved by local people.” 

There is nothing scientifically new to us in what Kareiva has said recently.  What’s new is that he speaks as a representative of one of the most important environmental organizations in the world.  Therefore, he makes a connection between scientific theory and action.  That is new….very, very, new and very encouraging.

Public policy always lags behind science

Public policy is inherently conservative.  It usually reflects consensus and consensus occurs late in every scientific debate.  Once that consensus is finally reached, changing it is a slow process.  And so, we are not surprised by the most recent example of a local community continuing the crusade to eradicate non-native trees.  Two ordinances were recently passed in the Los Altos Hills on the San Francisco peninsula, to do just that. 

  • Citizens building or expanding buildings on their properties will be required by ordinance 10-2.802 to cut down all eucalypts within 150 feet of any roadway or structure.
  • “Town guidelines concerning restoration action” (5-8.08) “deems certain trees undesirable,” including Monterey pine and cypress, as well as eucalyptus.

We are heartened by the publication which announces these new policies.  The author objects to being dictated to regarding her tree preferences.   She also responds to the usual myths regarding the negative qualities of eucalyptus.  In response to the usual justification for its eradication, that it is not native, the author says, “Who cares?”  Indeed, who cares?  We certainly don’t care and we speculate that the vast majority of people in Los Altos Hills don’t care either.  When we speak up on behalf of our trees, we speed the process of changing public policy to reflect the considerable scientific evidence that non-native trees are not harming anything or anyone.   Indeed, their eradication is causing far more harm to the environment by releasing tons of sequestered carbon and requiring greater herbicide use.
