For RFE forest ecosystems A.S. Sheingauz recently applied another assessment methodology based on rates of regeneration of disturbed forest measured over forest life cycles, that is, through silvicultural and biological forest parameters. Application of this alternate approach to 2003 state forest assessment data showed percent disturbance as 60 percent in Evreiskaya Autonomous Region, 46 percent in Amurskaya Oblast, 43 percent in Primorsky Krai, and 40 percent in Khabarovsky Krai. Methodology and result differs from other metrics that use artificial or subjective indicators (such as human-calculated logging and fire statistics) .
