Book Description
Excerpt from Evaluation of Multiple Regression Models for Prediction of Western Spruce Budworm Defoliation on Douglas-Fir No changes were made in the methods previously described by Bullard and Young (1980) for collection of egg mass and defoliation estimation data. Form 1 was designed and distributed to the field for collection of physical data describing those clusters already contained in the data base and any new clusters being added. Variables included were slope, aspect, elevation, physiographic location, stand structure, species composition, and basal area.

Book Description
Excerpt from Sampling Populations of Western Spruce Budworm and Predicting Defoliation on Douglas-Fir in Eastern Oregon A cluster design appeared to be the best solution for sampling these stages. For low, medium, and high populations, number and size of clusters per stand and number of stands were determined for means with an acceptable sampling error of 20 percent, at p z 0. 05, and also other precision and confidence levels. Sampling requirements were particularly great for low egg populations and medium populations of larvae in buds.
