Record #179790:

Modeling the location of the forest line in northeast European Russia with remotely sensed vegetation and GIS-based climate and terrain data / Tarmo Virtanen, and six others.

Title: Modeling the location of the forest line in northeast European Russia with remotely sensed vegetation and GIS-based climate and terrain data / Tarmo Virtanen, and six others.
Author(s): Virtanen, Tarmo.
Date: 2004.
In: Arctic and Alpine Research. (2004.), Vol. 36(3) (2004)
Abstract: Analyses structure of forest line at landscape level in lowlands of Usa river basin using GIS-based data sets. Constructs logistic regression models to predict forest location explained by July mean temperature, ground temperature (permafrost), annual minimum temperature and Topographic Wetness Index (soil moisture conditions). Suggests that anomalously high temperature isoline for forest line in North-East European Russia is due to inability of local ecotypes of spruce to grow on permafrost terrain. Models indicate that with climate warming of 3°C by end of 21st century, temperature would not limit forest advance in study area.
