Multi-Resource Land Allocation Model

MRLAM is a model for the identification of potential alternative land ownership patterns and their likely effects on species habitat and timber value.

Supports Analysis Of Interdisciplinary Interactions


Indicators Used

The Multi-Resource Land Allocation Model was developed to provide stakeholders in the Umpqua Land Exchange Project with an integrated analytical tool that allows for the identification of potential alternative land ownership patterns, and that evaluates the consequences of these alternative ownership patterns at a landscape scale on habitat for species at risk and timber value. More specific goals include the following:1. Design a model that can project habitat conditions at the landscape scale; 2. Address aquatic and terrestrial environments; 3. Project timber growth and harvest for federal, state, forest industry, and non-industrial owners; 4. Search for alternative ownership patterns that increase habitat for species at risk while maintaining timber values and capacity for timber production; 5. Communicate results in understandable ways; 6. Assist in the evaluation of alternatives in an EIS process; 7. Help citizen groups develop and evaluate proposed ownership patterns; 8. Provide analysis and display in “real time”; 9. Be interactive and user friendly.
