There is an increasing risk of local and global species extinctions where species are not able to move to higher elevations or other cooler locations , with risks from extreme events such as wildfire potentially exacerbating those risks . The topographic variation in mountains, such as elevation or aspect, may mean that some species will be able to survive in cooler microclimates. Mountain regions may act as refugia for some species from lower elevations if they can move into them. This may enable some species to persist in a region, though it may pose a threat to cold-adapted species, including endemics, which may be outcompeted ; invasive non-native species may become an increasing problem in some places.
