Recent above-ground biomass changes in central Chukotka (Russian Far East) using field sampling and Landsat satellite data
Upscaling plant biomass distribution and dynamics is essential for estimating carbon stocks and carbon balance. In this respect, the Russian Far East is among the least investigated sub-Arctic regions despite its known vegetation sensitivity to ongoing warming. We representatively harvested above-gr...

Upscaling plant biomass distribution and dynamics is essential for estimating carbon stocks and carbon balance.
