On the Ways of Forest Typology Researches in Siberia in the 1960s-2000s.

The article presents a brief overview of the works on forest typology and zoning of Siberia conducted at the Forest Typology Laboratory of the Institute of Forest and Timber of the USSR Academy of Sciences, later Sukachev Institute of Forest of the Siberian Branch of the Russian Academy of Sciences. The ecological and phytocoenotic line of research and the regional approach to the creation of diagnostic tables of forest types were adopted as a basis for complex field work carried out jointly with forest management throughout Siberia. The principal features of forest typological work in mountains required the improvement of the system of classification units and mapping of forest cover with determining their diagnostic indicators.

The Forest Observation System, building a global reference dataset for remote sensing of forest biomass.

Forest biomass is an essential indicator for monitoring the Earth's ecosystems and climate. It is a critical input to greenhouse gas accounting, estimation of carbon losses and forest degradation, assessment of renewable energy potential, and for developing climate change mitigation policies such as REDD+, among others. Wall-to-wall mapping of aboveground biomass (AGB) is now possible with satellite remote sensing (RS).
