Tree-tundra competitive hierarchies, soil fertility gradients, and treeline elevation in Glacier National Park, Montana

Auteur :
MALANSON, G.P.

Description :
The position of treeline on an elevation gradient is examined in relation to soil fertility. Soils were sampled at 25 treeline sites and analyzed for organic fraction, total nitrogen fraction, available phosphorus, and exchangeable potassium. The tundra-line may be lower where more nutrients are available because tundra species may more readily alter their competitive ability than do the tree species in this area.
