Abstract:
We undertook a large-scale forest inventory in central Chukotka in summer 2018 on a joint Russian-German expedition by the AWI (Potsdam) and the NEFU (Yakutsk). We covered different densities of larch forest plots accross the tundra-taiga gradient.
Tree height estitmations were conducted after training with a clinometer (SUUNTO, Finland) for trees present on 22 sites inventoriziong all trees (N=2624) on 15 m radial plots.
