The school board then began a process with the FWS to mitigate disturbance of the potential owl habitat on the site.

In a unit on owl habitat, for example, sixth graders examined rodent bones and fur to find out how much food owls consume.

Two important factors that influence the timber harvest are restrictions for spotted owl habitat and the emerging market for smaller-diameter saw-logs and veneer material.

Since April 1994, the forest is governed by the Northwest Forest Plan, which restricts, but does not eliminate, logging in potential spotted owl habitat.

One lumber company has promised to stop logging in spotted owl habitat, but many keep cutting.
