Quantitative Model Information in the ModelTracker Database: MTDB entries sometimes contain out-of-date VDDT model parameters.

Background:

ModelTracker Database (MTDB) reports often contain quantitative information about succession pathways and disturbance probabilities. This information in the MTDB model reports may be out-of-date due to the repeated iterations of review and revision. Every effort was made to correct the information through the review process, but it is possible that some MTDB entries were not updated. For example, an MTDB description might indicate that class A age limits are 0-1 years with a replacement fire at a 5-year return interval. However, the VDDT model, after review, indicates that class A age limits are from 0-2 years with a replacement fire return interval of 4 years. Errors of this type are most likely to occur in the “Vegetation Classes” section of the model description.

Advice:

Users should always open the model in VDDT to ensure that they have the correct information. Information in the VDDT model is considered to be correct when there is a discrepancy.
