In the Cordova Ranger District, permanent monitoring stations have been established on four point count transects and 2 BBS routes. Surveys have been conducted in these areas between 1992-1994. The Glacier District operates spring and fall banding and a MAPS (Monitoring Avian Productivity and Survival) station in Portage Valley. Seward Ranger District ran USFWS BBS route. Data is entered into a DBASE format and submitted to the Neotropical Monitoring Data Center in Redwood Science Laboratory, Arcata , California as part of and agreement with Region Ten USFS. These surveys will be conducted indefinitely as part of USFS contribution to the National Database.
