Abstract
The landscapes of the Taz Peninsula may be divided into three main relief types: present‐day depositional relief, biogenic‐cryogenic relief, and cryogenic‐erosional relief. Each is described in detail in terms of the processes involved in its development and as to the vegetation communities (subarctic and forest tundra) with which it is associated. The dangers associated with huma n activity in each of the three relief types is stressed, the greatest potential danger undoubtedly being that of accelerated thermokarst in the cryogenic‐erosional relief type.
