BACKGROUND MONITORING WITH LICHENS UNDER FLAMMABILITY RISK CONDITIONS BY THE EXAMPLE OF THE NORSKY RESERVE
Background monitoring with lichens under flammability rick conditions has its own peculiarities. By the example of the Norsky nature reserve (Amur region), the necessity is shown to select carefully the sample plots and wood species for lichenometric measurements. Abies nephrolepis is recommended. In the regions with flammability risk one often has to prefer constant sample plots to variable ones. Every sample plot must be with randomly selected model trees. This reduces intrinsic changes in lichen communities driven by endogenous succession.
