User's Guide for the Resource Ratings Modeling Tool (Version 3.xx)


Download and Install Tool

The RRM tool is part of the ERM System. It is an add-in for Excel and was developed to assist biologists in populating resource ratings tables (RRTs).

Usually, in order to populate a RRTs with ratings, many assignments are manually made even though relatively few decisions are made. The RRM method provides definitions, concepts, and structure to document the few decisions. The RRM tool is software that facilitates application of the RRM method by automating the process of making numerous assignments. The RRM method and tool are being investigated as an alternative process for populating ratings tables and do not replace or alter the current RISC[formerly RIC] standard (BC Wildlife Habitat Rating Standards 1999).

BEI, PEM and TEM, and VRI are used extensively to provide baseline ecosystem information. Resource ratings tables provide the resource values of each mapped 'ecosystem unit'. Subsequently the ratings are used to produce map themes that are used for resource planning. (The VRI sample model contains all data required to generate sample themes)

The ratings are normally applied manually by an ecosystem interpreter to each ecosystem unit for each resource. By automating this procedure using the RRM tool, the interpreter's reasoning is more transparent (but still based on expert opinion). The result is a streamlined process for integrating resource knowledge into resource planning initiatives that will better support management of resources throughout the province.

Applicability of RRM method and tool

The RRM method and tool are applicable to BEI, PEM, TEM, and VRI and they can be applied to any system in which attributes are measured or recorded, and the attributes are related to resource values. For example, these sample models are made using inputs from VRI, BEI, and PEM.
