Describes methods of designing natural resource monitoring programs to provide indications of ecosystem health, define limits of normal variation, identify abnormal conditions, and suggest potential agent of abnormal change. (MDH)

Disturbance-generated biomass results from endogenous and exogenous natural and cultural disturbances that affect the health and productivity of forest ecosystems. These disturbances can create large quantities of plant biomass on predictable cycles. A systems analysis model has been developed to quantify aspects of system capacities (harvest,…

Presents two statistical topics and examples of their use in natural resource monitoring. The first topic deals with use of correlated observations in calculations of variance estimates for a regional mean, required sample size determination, and confidence intervals. The second topic concerns the use of Bayesian techniques in hypothesis testing.…

The objective of this paper is to explore the state of recent recreational research by U. S. Geographers and social scientists. This report views the importance of recreationalists behavior patterns and describes the use of simulation models to predict demand data. Four research phases constitute the main organization of this paper: 1)…
