Monitoring Bird Populations on National Forest Lands: Chippewa National Forest, 1992

Abstract

A habitat specific bird monitoring was established on the Chippewa National Forest in 1991 (see Hanowski and Niemi 1991a, 1992). 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 for 1992 monitoring were to: (1) make statistical comparisons between 1991 and 1992 bird abundance; (2) determine the power of statistical analyses in terms of detecting annual differences for a variety of bird community, guild, and species specific parameters; and (3) explore similarities and differences in habitat data collected and the U.S. Forest Service forest types.
