| 520 | |a"Procedures are described for designing a ground-survey for Phellinus weirii root rot in forest stands. Office procedures include selection of baseline location and number, location and width of transect lines. Field procedures include measurement of infection centers by intersection length, rectangular, radialor linear methods. Five survey method options include measurement of infection centers, estimation of infection center area, assignment of infection centers to size classes, measurement of intersection length, and assignment of intersection length. Methods for recording, analyzing and summarizing field data are described for intersection length and probability of occurrence methods. A computer program for analyzing and mapping the data is described. Three mapping options provide a range of detail in maps of infection centers."--Summary, page 2. |
