Abstract : A report on the line intercept vegetative sampling technique is provided as Section 6.2.5 of the U.S. Army Corps of Engineers Wildlife Resources Management Manual. This technique can be used by the Corps District or project biologist to estimate percentage ground cover of shrub communities on project lands. Topics covered include guidelines for technique selection and study design, preparation for sampling, and procedures for data collection, recording, and analysis. Forest inventory techniques are not generally appropriate for sampling shrub ecotypes, but line intercept can be readily applied in habitat evaluation or range inventory of typical shrublands. Sampling can be conducted by either 2 or 3 field personnel. Cover estimates are made by measuring the lengths of tape line intercepted by shrub canopies and calculating the percent ground cover represented by these lengths. Detailed instructions are given for recording and analyzing data; these are accompanied by numerical examples that illustrate each step of recording and data analysis. A reproducible form is also provided for recording and calculating line intercept data.
