Dbh to basal area
WebA single 10 cm DBH tree only has a basal area of 0.00785 m^2 while each 50 cm tree is 0.196 m^2 (= PI * Radius^2 ). We do not want to waste time measuring too many small trees, but do not want to miss the big values contributed by the large trees, so we use 2 circular plots of 5 m and 25 m radius and measure only small and large trees ...
