WebFormula used: A = πR² ÷ 43560 (there are 43560 ft² in one acre) where A = area R = radius π = 3.14159 example: diameter of plot = 66 feet (ft)--R = diameter ÷ 2 66 ÷ 2 = 33 ft for the radius 3.14159 * ( 33*33) ÷ 10000 = A 3.14159 * 1089 = 3421.19151 ÷ 43560 = 0.07853975 acres (ac) or 1 ÷ 0.07853975 = 1 : 12.7 of an acre (ac) Fixed Area Plots, Acres WebA fixed plot will be used to sample those trees less than 5.5” DBH (regeneration trees). The size of the fixed plot will depend on the anticipated density of the regeneration within the stand. If it appears the density is sparse, then a 50th … WebMar 6, 2024 · Benefits of Fixed-Radius Plots For example, forest managers can calculate trees per acre (TPA), a common measure of stand density, by multiplying the number of trees measured within a plot by the plot size. (Example: 10 trees measured in a 1/10-acre plot would represent 100 trees per acre). How many trees are there in a forest? fate zero
