Climate Change Imperils Efforts to Save Lynx from Extinction, Study Finds

Almost 100 million euros (U.S.$ 130 million) has been spent so far on conservation efforts for the last 250 remaining Iberian lynxes in the wild, but the world’s most endangered cat species is likely to go extinct within 50 years because the management plans do not provide for the effects of climate change, researchers warn.

“Our models show that the anticipated climate change will lead to a rapid and dramatic decline of the Iberian lynx and probably eradicate the species within 50 years, in spite of the present-day conservation efforts. The only two populations currently present, will not be able to spread out or adapt to the changes in time”, says Miguel Araújo from the Center for Macroecology, Evolution and Climate at the Natural History Museum of Denmark at the University of Copenhagen.

Araújo and colleagues explain that the Iberian lynx is threatened by poaching, road kills, habitat loss and lack of prey following a series of disease outbreaks in the rabbit populations. “Therefore, significant investments are currently made to relocate rabbits, prevent diseases, reduce threats and improve the lynx’s natural habitat. Unfortunately it is not enough, show new models that investigate how climate change will influence the availability of prey and quality of natural areas in the future.”

“Fortunately, it is not too late to improve the outlook for the endangered lynx, if the management plans begin to take account of climate change,” Araújo adds in a news statement about the study.

The scientists modeled two other scenarios for the Iberian lynx, both based on a future prospect for releasing individuals from breeding programs into wild areas. “They paint a more optimistic picture for the lynx’s survival, but the models clearly show that release programs also need to account for future climate change in order to achieve the best possible result,” they explain in the news release.

“While Spanish policymakers are considering releasing lynxes evenly across the country’s autonomous regions, the scientists’ models predict the most suitable areas to be in the northern half of the Iberian Peninsula. These areas could ultimately deliver both prey abundance and habitat connectivity in spite of climate change.

“According to the models it may increase the population up to nearly 900 individuals by 2090. In comparison, the geopolitical strategy will at best maintain the population around the current 250 individuals.”

The study, published in Nature Climate Change, is the first of its kind to clearly demonstrate the importance of modeling climate change, prey availability and their interactions in the development of management plans, the news release concluded.
