Predictive Ecosystem Mapping (PEM) Detailed Polygons with Short Attribute Table - 1:20,000 Spatial View


PEM_20K contains 1:20,000 PEM polygons with key and amalgamated (concatenated) attributes derived from the Resource Inventory Standards Committee (RISC) standard attributes. PEM divides the landscape into units according to a variety of ecological features including climate, physiography, surficial material, bedrock geology, soils and vegetation. PEM uses a modeling approach to ecosystem mapping, whereby existing knowledge of ecosystem attributes and relationships are used to predict ecosystem representation in the landscape. This layer is derived from the STE_TEI_ATTRIBUTE_POLYS_SP layer by filtering on the PROJECT_TYPE and PROJECT_MAP_SCALE attributes

PEM is the stratification of a landscape into map units, according to a combination of ecological features, primarily climate, physiography surficial material, bedrock geology, soil, and vegetation. PEM provides: a biological and ecological framework for land management; a means of integrating abiotic and biotic ecosystem components on one map; basic information on the distribution of ecosystems from which management interpretations (e.g., broad-scale landscape planning, site-specific interpretations) can be developed; a basis for rating values of resources or indicating sensitivities in the landscape; a historic record of ecological site conditions that can be used as a framework for monitoring ecosystem response to management; and a demonstration tool for portraying ecosystem and landscape diversity. This dataset should be used and interpreted in consultation with a qualified ecosystem and/or terrain mapper.
