Monitoring Bird Populations on National Forest Lands: Chippewa National Forest, 1993

Abstract

A habitat specific bird monitoring program was established on the Chippewa National Forest in 1991 (see Hanowski and Niemi 1991b, 1992b). The objectives of the program were to: (1) establish the physical layout of the monitoring program (2) monitor abundance of indicator bird species that have been specified by the Forest; (3) monitor abundance of common bird species in the Forest; and (4) begin refining avian/habitat relationships used to assess forest management activities on breeding bird abundance and distribution. Additional goals implemented during 1992 were to: (1) determine the power of statistical analyses in terms of detecting annual differences for a variety of bird community, guild, and species specific parameters; and (2) explore similarities and differences in habitat data collected and the U.S. Forest Service forest types. Objectives for 1993 focused on making statistical comparisons between 1991, 1992, and 1993 bird abundance.
