These findings are of particular interest when considering reserve design. At the edges of a reserve, presuming that the reserve is also the species range if the species is highly threatened, climate change will be far more of a factor. Northern borders and those at higher elevations will become future battlegrounds for the conservation of the species in question, as they migrate northward and upward. The borders of today may not include the habitat of tomorrow, thus defeating the purpose of preservation by instead making the species range smaller and smaller if there are barriers to migration at the Northern and higher elevation boundaries of the reserve. Reserves could be designed to keep Northern migration a possibility, with boundaries farther to the North than might be considered practical looking at the today’s species ranges and abundances. Keeping open corridors between reserves connecting them to reserves to the North and the South is another possibility.
