General Technical Report INT-GTR-340).  aThe Columbia River Basin SUccession Model (CRBSUM) simulates broad-scale landscape changes as a consequence of various land management policies. CRBSUM is a spatially explicit, deterministic model with stochastic properties that simulates changes in vegetation cover types and structural stages on landscapes over long periods. CRBSUM was used to simulate coarse-scale landscape changes in the Interior Columbia River Basin as a result of four management scenarios called management futures. CRBSUM results have an inherent 1 to 5 percent variability because of the stochastic structure of the model. Sensitivity analysis results suggest moderate changes in disturbance probabilities (25 percent increase) will only slightly affect simulated results.  avegetation  aBacia Hidrográfica  aEcossistema  aVegetação  aComputer model  aEcosystem  aGIS  aHidrographical basin  aInterior Columbia River Basin  aLoki simulation system  aStochastic model  aSuccession modeling  aSuccession pathways1 aLONG, D.
