"Fixed Area Plot Sampling for Forest Inventory: Section 6, 2, 4, U.S. Army Corps of Engineers Wildlife Resources Management Manual"@en . "The fixed area plot technique can be used by biologists and natural resource managers for forest inventory. It is an appropriate method for determining major forest stand parameters such as species composition, density, and basal area. Equipment is inexpensive, and the technique is easy to apply. Topics include guidelines for technique selection and study design, preparations for sampling, and procedures for data collection and analysis. Detailed instructions are given for recording and analyzing data; these are accompanied by numerical examples that illustrate each step of the calculations. Reproducible data forms are provided for project use. (MM)."@en . . . . . . . . "Wildlife Resources Management Manual"@en . . . .
