Pollen productivity estimates and regional vegetation estimates in west Siberian Arctic tundra, a work in progress
Pollen-based reconstructions of land-cover by using the landscape reconstruction algorithm (LRA) have been produced for several years in the most populated areas of the world. This is not the case in the Arctic tundra, partly because of the lack of pollen productivity estimates (PPE) of the tundra v...

Pollen-based reconstructions of land-cover by using the landscape reconstruction algorithm (LRA) have been produced for several years in the most populated areas of the world. This is not the case in the Arctic tundra, partly because of the lack of pollen productivity estimates (PPE) of the tundra vegetation, partly because the area is virtually uninhabited and hence not in a significant role when the focus is on land-use change and its role in the anthropogenic climate forcing. Reindeer (Rangifer tarandus) is the dominant large herbivore affecting the vegetation of the northern Eurasian tundra. It has been observed throughout the Arctic, and especially in Fennoscandia and northern Russia, that human-animal impact, e.g. concentrated grazing and trampling by semi-domesticated reindeer herds have changed the vegetation at large by creating graminoid dominated green patches, which have persisted over the centuries in some places.
