Book Description
Excerpt from Insect-Caused Mortality in Relation to Methods of Cutting in Ponderosa Pine on the Blacks Mountain Experimental Forest For this reason, entomologists began collecting records of mortality on the plots from the start of the tests. These records were taken yearly, once the plots were cut, from 1939 through 195a. Recently, the mortality records were analyzed by the Station's Division of Forest Insect Research. The purpose was to determine (1) if insect-caused losses were correlated with method of cutting; and (2) if differences in losses by method were great enough to warrant continuing annual measurements. This report contains an analysis of the mortality data obtained, and summarizes the results and conclusions derived therefrom.
