forestr. | plot method | участковый метод (Лесоустройство • The "plot method" in forest inventory involves establishing sample plots of fixed or variable sizes in a forest to gather data on trees, allowing for extrapolation of these findings to estimate forest-wide characteristics like volume, biomass, and growth. Key aspects of plot method design include selecting the shape, size, number, and distribution of plots, often using systematic, stratified, or random sampling techniques. Common plot designs feature a central plot with smaller subplots or microplots, as exemplified by the Forest Inventory and Analysis (FIA) program's cluster plot design.
