Establishing cause-effect is critical in the field of natural resources where one may want to know the impact of management practices, wildfires, drought, etc. on water quality and quantity, wildlife, growth and survival of desirable trees for timber

Almost any type of sample has some utility when estimating population quantities. The focus in this paper is to indicate what type or combination of types of sampling can be used in various situations ranging from a sample designed to establish cause

We show that the Annual Forest Inventory System (AFIS) being developed by the USDA Forest Service and tested in the state of Minnesota is no more costly than the periodic Minnesota forest inventory (12 year measurement cycle). Since very useful resul

Poisson (3P) sampling is a commonly used method for generating estimates of timber volume. The usual estimator employed is the adjusted estimator, Y hata. The efficiency of this estimator can be greatly influenced by the presence of outliers. We form

Equations for predicting tree volume are often developed using data collected either by a model-based method such as purposive sampling or by stratified random sampling so that an "adequate" number of trees from each diameter class are sampled across

A conceptual framework is given for a broad-scale survey of forest health that accomplishes three objectives: generate descriptive statistics; detect changes in such statistics; and simplify analytical inferences that identify, and possibly establish

Point-model based sampling is described for timber inventory. Point-model based sampling is an improvement on point-3P sampling because the number of sample trees selected for detailed dendrometry is completely controlled. Field studies indicate that

Regression estimation in finite population sampling drawing one unit per stratum is considered in the paper. It is proved that under mild conditions,the generalized regression estimator proposed by Sarndal (1982) converges in probability to the popul
