Habitat corridors could help save wildlife from climate change

Over the next century, as temperatures climb, precipitation patterns shift, and sea levels rise, there will be a dramatic altering of the American landscape.

 

Faced with these changes, some plants and animals will either have to adapt or flee to new, colder homes in order to survive. In fact, a number of species have already begun shifting their habitats, with most moving towards the poles or to the higher elevations of the mountains. Some animals might even need to move many hundreds of miles over the next half-century.

 

But, the untouched forests, deserts, mountains, and parks that these species call home are fragmented and divided by human development, such as cities, agriculture or roads. This, more often than not, leaves species no escape route if climate change continues to make their habitats inhospitable.

 

A new study , published today in the journal Proceedings of the National Academy of Sciences (PNAS), found that only 41% of today’s natural areas are sufficiently connected to allow plants and wildlife to remain in their optimal climate.

 

The situation is even more dire in the eastern US: only 2% of natural lands provide the kind of connectivity needed for species to flee, compared to 51% in the west. Not only is the east more densely urbanized, but it also has less of a climate gradient due to smaller, older mountains. The west, in contrast, has much taller mountains (providing a bigger climate gradient) and much bigger swaths of untouched wilderness.

 

Species need “little plant and animal highways, paths that make it easier to move and disperse over the landscape,” Jenny McGuire, study author and research scientist at the Georgia Institute of Technology’s School of Biology, told Business Insider.
