Recent changes in mountain birch forest structure and understory vegetation depend on the seasonal timing of reindeer grazing

Sari Stark, Henni Ylänne & Jouko Kumpula
1. Subarctic forest-tundra ecotones dominated by mountain birch (Betula pubescens ssp. czerepanovii) is an important habitat for semi-domestic reindeer (Rangifer tarandus). The seasonal timing of reindeer grazing may direct vegetation trajectories in these systems, because in the summer ranges, mountain birches are subjected to browsing, while in the winter ranges, reindeer feed on understorey vegetation and arboreal lichens but leave the mountain birches intact. 2. Based on earlier research, we predicted that (1) summer browsing...
