Range Expansion of Moose in Arctic Alaska Linked to Warming and Increased Shrub Habitat
Fig 3
Overlapping areas of northern moose distribution (brown outline) [14,15], earlier spring onset (shaded) [74], and documented shrub expansion (green dots) [3,4].
Shaded areas indicate trends in spring snow cover duration 1972–2008 (see legend). The green line denotes treeline. Increasing shrub habitat along the northern edge of moose distribution portends northward range extension of moose across the Arctic.
