Climate Change Forces ‘Move It Or Lose It’ Conservation Approach?

05.10.2010
What does it take to save a species in the 21st century? The specter of climate change, with predicted losses to biodiversity as high as 35 percent, has some scientists and managers considering taking their conservation strategies on the road.

Managed relocation (MR) is literally the physical relocation of endangered or threatened species of plants and animals, by humans, to new, and foreign geographical climes. It addresses the concern that climate shifts may make many species’ historical ranges environmentally inhospitable, and that the rapid speed of change and habitat fragmentation will prevent them from adapting to these new conditions or moving themselves.

And while conservationists argue that the practice may not preserve some species, such as the polar bear, relocation is a hotly debated option for others’ long-term survival.

Arizona State University environmental ethicist Ben Minteer and ecologist James P. Collins ask hard questions about the practice, also known as assisted colonization, assisted migration or assisted translocation, in their article “Move it or Lose it” published October 1 in the journal Ecological Applications.

Stress on native species is just one of the unknowns that come into play with translocation of species. There also remains the more critical question of how to evaluate such management decisions, according to Minteer, an associate professor in ASU’s School of Life Sciences and researcher in the Center for Biology and Society, and Collins, a Virginia G. Ullman Professor of Natural History and the Environment in ASU’s School of Life Sciences in the College of Liberal Arts and Sciences.

“New approaches to conservation, such as MR mean the need for a new ‘ecological ethics’ geared toward problem-solving in ecological research and policy,” says Minteer. “Beyond asking ‘should’ we do it, there’s the more pragmatic ethical question: what separates a ‘good’ from a ‘bad’ MR activity?” In a time of rapid global change, Collins says that “ecologists and biodiversity managers will have to think hard about not only what management actions are possible, but also which ones are acceptable ethically.”

Such discussion is as critical as the technical and scientific questions of relocation: the “can we do it and how we do it,” the authors state.

Minteer points out that while moving species around is nothing new, the climate change rationale for doing so is. “Looking past creating parks and shielding species from bullets, bulldozers and oil spills in favor of the anticipatory relocation for conservation purposes strikes many as different, in terms of motive and perhaps the extent of the consequences.”

Minteer and Collins’s call to reassess conservation goals in the face of climate change is timely. While the practice has no guarantees of success, managed relocation of species is already being put into practice. The Florida torreya tree is an example, along with the proposed relocation of the Quino Checkerspot butterfly and the Iberian lynx.

Collins says that the real scientific concern with species relocation – voiced by prominent skeptics – is that crossing evolutionary boundaries via managed relocation will produce a number of negative ecological and genetic consequences for species and systems on the receiving end.

How to leap the ethical gulf separating decisions about which species should be moved and “saved” is also critical to the debate. Though some argue that human activity has already played an active role in shifting species and that some populations are “naturally” undergoing range shifts without assistance due to climate change in response to human pressures as well as natural ones.

However, as Minteer points out, “There is also the more philosophical objection to the fact that ‘we’ are doing this, rather than the populations themselves, and that this is therefore another example of human arrogance toward wild species and the environment more generally.”

Does the shift to focus on relocation strategies mean that more traditional routes to preserve species, such as species migration corridors that connect forest patches, will become anachronistic?

“Traditional philosophy and policy of conserving species will likely change to reflect a more anticipatory and interventionist mode of thinking,” Minteer says. “What this spells for conventional norms of ecological preservation is that they may have to give way to a more dynamic and ‘novel systems’ model rather than historical ones.”

In other words, the “metabolism” of conservation will have to speed up to keep in step with climate change, Minteer believes.

Some believe that the distraction from the use of traditional protected areas and historical systems models, will also, once managed relocation is legitimized, open the floodgates and that people will start moving species willy nilly around the landscape. “I think that fear is exaggerated, though the precedent that would be set for ecological policy by formally adopting MR, even as a last resort, is indeed a significant issue,” says Minteer.

“How to formulate new approaches to ecological research and management landscapes in an era of rapid and global environmental change raises original and difficult ethical questions about how to save species and protect landscapes,” Collins states. “We can improve the decisions we make by using more collaborative and interdisciplinary approaches to such problem-solving and decision-making.”

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
