A collection of samples used to make inferences about a population. Non-overlapping collections of elements which are intended to be representative of a population. A sampling procedure where a sample of size n is drawn from a population of size N in such a way that every possible sample of size n has the same chance of being selected. An ecosystem classification for land areas capable of supporting a specific climax plant association and reflecting a specified range of soil moisture and nutrient regimes within a subzone or variant. This includes traditional wildlife range determination and habitat association inventories.
Species statusing enables prioritization of animal inventories and population monitoring.
All of these activities are included under the term inventory. The ability to draw conclusions about a population parameter from an analysis of the sample data. The separation of a sample population into non-overlapping groups based on a habitat or population characteristic that can be divided into multiple levels. Groups are homogeneous within, but distinct from, other strata. A discrete area within a project boundary in which sampling actually takes place.
