An environmental analysis has been prepared which describes and evaluates the management alternatives for the timber harvest and burning within the Tenderfoot Creek Experimental Forest (TCEF) project area. The project area lies within the headwaters of the Tenderfoot drainage of the Lewis and Clark National Forest. The purpose of this biological assessment is to review the possible effects of the preferred alternative on endangered, threatened, proposed and candidate species and their habitats in order to determine whether or not a 'may adversely affect' situation exists. This assessment, which was first written in 1997 was updated in 1998 to reflect the status of lynx.
