Monitoring the Health of the Sierra Nevada

Case Overview

The 1982 National Forest Management Act regulations require the Forest Service to identify and monitor the populations of various management indicator species (“MIS”) in the national forests. These particular species serve as a bellwether for other species with the same special habitat needs or population characteristics, so monitoring MIS is a way of monitoring the health of forest wildlife and habitat more generally. 


On December 14, 2007, the Forest Service amended the forest plans for all ten national forests in the Sierra Nevada. The amendment reduces significantly the number of MIS that will be monitored, increasing the risk that logging and other destructive activities will be carried out that will harm wildlife and habitat in the Sierra.


This suit challenges this amendment to the Sierra Nevada forest plans.
