RESEARCH METHODICAL FEATURES OF ALDER FORESTS MORTMASS OF UKRAINIAN POLISSYA

Methodical evaluation features of woody debris in forest ecosystems and components classification features of coarse woody debris, fine woody debris and forest ecosystem mortmass have been processed. The state of complex forest mortmass evaluation for solving the problem of forest ecosystems biological productivity, biodiversity and the carbon cycle of forests have been analyzed. The state research of dead trees mortmass, coarse woody debris, fallen coarse branches and litter have been analyzed. It has been found out that the data on mortmass dynamics in forest plantations are rather limited for basic forest species in Ukraine. There have been presented methodical features of forest ecosystem mortmass devision for their main components and destruction classes depending on its dimensional location, size and quality state. Morphological features of black alder forest mortmass components in Ukrainian Polissya have been analyzed. It has been found out that for the complex research of the dynamics of alder forests biological productivity, the process of accumulation and mortmass destruction including deadwood, coarse woody debris, fallen coarse branches and litter must be estimated. It was noted that at the current stage of alder mortmass research, there are no data on forming patterns of deadwood and coarse woody debris and its destruction.
