| 520 | |a"A transect line sampling system comprising sets (grids) of Iines was developed to estimate the incidence, distribution and area of root rot caused by Phellinus weirii (Murr.) Gilbertson in Douglas-fir stands. Estimates of total area of root rot were derived from intersection length and probability of occurrence; the latter was also used to estimate area and number of infection centers by size class. In simulated stands, two methods of measuring infection centers, radial and linear, gave accuracies of 96-109 and 94-114% of true area, respectively"--Summary, page 2. |
