Saving Wildlife In A Warmer Climate

NRDC and their Louisa Willcox are so right on this.  Even the US Fish and Wildlife Service, way tepid under W. Bush,  is looking for solutions to a climate that will change and a series of habitats that are already changing. This cannot be written better by anyone!!!!Please read.

Whether it’s a polar bear clinging to a melting iceberg in the Arctic or a tiny, rabbitlike pika panting atop a warming mountain in western North America, scientists say that these species and others could be historical footnotes unless people help them survive.

Pushing animals to the brink – and then trying to bring them back – is nothing new for humans. Remedies have long included setting aside land for a special habitat (spotted owls) or making it illegal to kill them (whooping cranes).

But sweeping changes that would accompany projected climate change mean that an animal’s traditional range may no longer be habitable to it in a few years – or that a key food source or resource it needs is disappearing. And that calls for different solutions from those in the past.

“The business-as-usual approach to managing wildlife populations and resources is no longer likely to work very well,” says John Wiens, chief conservation science officer for the Point Reyes Bird Observatory in Petaluma, Calif. “We can’t say anymore, ‘Hey, we’ll do some management to control this threat, and everything will be hunky-dory,’ or ‘Preserve some habitat and some organisms, and everything will be fine.’ ”

There are signs of positive action, however. After years of what many saw as foot-dragging, the US Fish and Wildlife Service (FWS) is leading states and other organizations in taking the first steps toward what could become a radical departure from today’s species-recovery model.

The FWS’s plan is a comprehensive and predictive “adaptation management” plan to help troubled wildlife. Its centerpiece is the creation of eight new regional landscape conservation cooperatives (LCCs), the first of up to 20 nationwide that will enlist multiple partners to deal with global warming’s expected effects.

Along with the US Geological Survey (USGS), states, and others, the FWS is now holding regional conferences on how to shape the cooperatives.

“We’re just at the very beginning stages of LCC development,” says Dan Ashe, deputy director of the FWS, in a phone interview. “We have to be able to be more predictive, to be able to look into the future to how climate change is affecting species like the grizzly bear, polar bear, or coho salmon.”

Gazing into the future is the key. Last month, Congress provided $25 million in fresh funding for the cooperatives, each of which will have a core staff of scientists to create models of probable regional climate impacts and provide scientific analysis for future wildlife management plans.

“The LCCs are integral to climate adaptation efforts,” according to an internal agency draft “function and form” document. Even so, they will not be “climate-centric,” but will “provide scientific support for conservation actions addressing a variety of broad-scale challenges, including water scarcity, species invasion, wildlife disease, as well as changing climate.

Using advanced computer models, LCC scientists will report how global warming could change regional ecosystems decades from now, allowing researchers to calculate whether a recovery plan in a species’ home range makes sense.

That, in turn, might make it possible to determine if a wildlife corridor, a way for animals to migrate past highways and cities to cooler northern climes, is possible. Or whether more drastic measures – such as translocating a species (capturing and moving it) – are necessary.

Scott Loarie’s pioneering work points to a decline of up to 59 percent in pika populations across the western US if greenhouse-gas emissions reach the higher end of the scale predicted by the International Panel on Climate Change. Even under the most optimistic IPCC scenarios, 15 percent of pikas would disappear. Higher levels of decline could bring calls for more radical adaptive techniques.

Options for the pika, which requires temperatures below 80 degrees F., could include spending more time underground to avoid the heat. But that may mean pikas couldn’t graze sufficiently to get fat enough to survive the winter. says Dr. Loarie, a researcher with the Carnegie Institution for Science at Stanford University in California.

However, “if policymakers create larger areas that lessen sheep grazing and logging at higher altitudes, that management might help their chances a lot,” Loarie says.

More radical measures, such as translocating pikas, are hotly debated. “Translocation of the pika brings up all kinds of ethical questions, mainly the issue of native versus invasive species,” he says.

“If you take a climate refugee and bring it to another range, does it become an exotic species? It opens a huge can of worms,” he says. “Do we know enough to engineer things to get the outcome we want or [do we] risk making things worse?”

What’s become clear is that saving wildlife species threatened by climate change requires global cooperation, which presents challenges to scientists and negotiators.

Last month, for example, the FWS identified more than 200,000 square miles as critical habitat for the endangered polar bear. “We’ve listed the polar bear under the Endangered Species Act here in the US, but we can’t begin to conserve them just within our own borders,” Mr. Ashe says. “We are having to reach out to nine countries that manage them to put together an adaptation strategy.”

Climate impacts can appear suddenly, even for species that had been recovering well. The grizzly bears of Yellowstone National Park are an example. Their numbers had been rebounding, but now climate change-linked beetle infestations and disease have killed 60 percent of the white bark pine in Yellowstone – and much of what’s left is expected to be dead in five to seven years.

White bark pine nuts are a critical food that helps grizzlies get fat enough to overwinter. With the white bark pine gone, some 300 to 400 grizzlies need to spread out to other areas to find food. Bears are already turning to elk as a food source and getting shot by frightened elk hunters as a result.

    Hello Matt,

    I am a 4th year Visual Communication Design student at Arizona State University. For our senior thesis, we are required to pick a social issue and do a presentation on our research and findings, including an exhibition at the end of the year. I have selected the topic of poaching and its effects on endangered species. After coming across your weblog, I found various postings to be intriguing and helpful in my research.

    I would be honored to learn more about your background and use you as a possible source or advocate for my research and presentation. If this interests you, please let me know.

    I look forward to your response,

    Hello Paula:
    Good topic. You can get most of this off of my profile on this blog. I actually know more about your chosen topic then I dp about global warming. I was a certified wildlife biologist and was a past Executive Director of the Great Bear Foudundation, the Sandoway House Nature Center and the Coosa Basin Initiative,

    I taught Endangred Wildlife for the Wildlands Researh Program for San Fransico State University. I taught Bears and Ecosystems Field Studies for Montana State Univrrsity.

    Since 2006 I have been disabled with a disease.
    My full name is Matthew M. Reid.
