Book excerpt: 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.
