Highlights
The management of the endangered Kirtland’s warbler and the jack pine system on which it depends has been hailed a conservation success story
The core of the Kirtland’s Warbler breeding range is concentrated in five counties in northern Lower Michigan (Ogemaw, Crawford, Oscoda, Alcona, and Iosco), where more than 86% of the singing males have been recorded since 2000, with nearly 33% counted in Ogemaw County alone and approximately 15% in just one township (MDNR, unpubl. data; Figure 2)
74,100 acres were on state forest lands in 16 management areas in nine counties and about 53,500 acres were on federal forest lands in seven management areas in four counties (USFS and Michigan Department of Natural Resources (MDNR) 1981)
Summary
The Kirtland’s Warbler (Setophaga kirtlandii) is a federally endangered migratory songbird that nests exclusively in young jack pine forests in northern Michigan, Wisconsin, and Ontario. The subject matter scope of the plan was limited to ensure that the focus remained on conservation of Kirtland’s Warbler It is the agencies’ intention to cooperate with partners to expand the scope of the plan in the future to address migratory and wintering habitat, and revisions may be more holistic in nature, widening the scope to include more of the jack pine ecosystem. To ensure the survival of the Kirtland’s Warbler, agencies will need to continue habitat and cowbird management into the foreseeable future This plan is complementary to existing agency plans and each agency will continue to contribute and cooperate to manage the Kirtland’s Warbler population and after the species is delisted (removed from federal Endangered Species Act protection).
