Northwest Forest Plan Aquatic And Riparian Effectiveness Monitoring Program

The goals of the Aquatic and Riparian Effectiveness Monitoring Program (AREMP) are to determine present watershed condition, track trends in watershed condition over time, and report on the Northwest Forest Plan's effectiveness across the region. To account for biophysical differences across the region, the AREMP team divided the Plan area into seven biophysical provinces and held a series of expert workshops to develop a model for each. Models are being developed using the Ecosystem Management Decision Support (EMDS) system and are run on data summarized to 6th field hydrologic units (~10,000 � 40,000 ac).

A relatively simple evaluation model (roads & vegetation) was used for a complex concept.

Although the Northwest Forest Plan has been highly contentious, this analysis was not, most likely because it was not directly tied to any allocation of resources.

Neither scientists nor stakeholders complained about simplicity, and both supported the attempt at making the evaluation explicit and quantitative.

Results were presented to the Regional Interagency Executive Committee, but there are no clear mechanisms for how results are expected to influence decision making.
