Changes in snow coverage threatens biodiversity of Arctic nature

Many of the plants inhabiting northern mountains depend on the snow cover lingering until late spring or summer. Snow provides shelter for plants from winter-time extreme events but at the same time it shortens the length of growing season, which prevents the establishment of more southern plants. This is why the reduced snow cover may be an even larger threat to the Arctic plants than rising temperatures. https://www.sciencedaily.com/releases/2018/10/181023110630.htm
