Papers PHYTOECOLOGICAL STUDY OF SYLVOTUNDRA AT SMALL TREE LAKE, N.W.T.l
ABSTRACT. Characteristics of terrain and the associated microenvironmental conditions deter-mine various vegetation types in the study area. Lakeshores and hill-bottoms support closed canopy Picea mariana forest, but the exposed slopes are treeless. A Picea glauca parkland forms a transition between...
