Monitoring for Tomorrow s Habitat -Approach Statewide Comprehensive Focus on key habitats Identify a common set of indicators Integrate existing information Fill monitoring gaps
KEY HABITATS Prairies, surrogate grasslands, savannas Key river reaches Lakeshores Wetlands Upland & lowland coniferous forest Amount Quality Associated species in greatest conservation need
Forest Wildlife Research Group Prairie-chicken Lek Survey (1960 s, 1974-2003, 2004-2006) Sharp-tailed Grouse Lek Survey (1940 s, 1976-2006) Ruffed Grouse Drumming Survey (1949-1981, 1982-2006)
Waterfowl Breeding Population Survey 1968-1971 (archives) & 1972-2006 (digital) May 1-25 (focus on breeding mallards in Prairie and Transition zones) 115 aerial transects (0.25-mi wide) Double sampling (14 air-ground segments) to estimate visibility corrections Estimated total ducks (by species) and May ponds in sampling frame Annual report (MNDNR public website) Steve Cordts (MNDNR, Bemidji)
Statewide Bald Eagle Surveys Statewide surveys every 5 years: 2000 & 2005 completed
Statewide Bald Eagle Survey Number of known active bald eagles in Minnesota 1973-2005
Northern Goshawk Project 2003-Present Surveys for goshawk in new areas in NE Minnesota Monitoring an average of 64 nests per year Habitat assessment and management plans for territories
Minnesota Loon Monitoring Program 1989 Loon Survey 12, 052 + 1398 adult loons in Minnesota Developed monitoring program in 1994 because: Historical declines have occurred Minnesota contains over 50% of breeding adults in the lower 48 states Current anthropogenic threats exist People care about loons.
Piping Plover and Common Tern Monitoring The Lake of the Woods area is the only remaining breeding site for piping plovers in Minnesota. Nesting common terns are also assessed annually
Minnesota County Biological Survey Breeding bird surveys
MCBS Statewide 1988-2006 breeding season bird surveys 69 counties completed +5 partially completed 5,431 survey locations 4,454 point counts 977 species lists 73,000+ bird records
Animap : MCBS common animal data
Minnesota Owl Survey Routes In 2005, 51 MFTCS routes used to conduct owl surveys. 31 new routes added to initial study area in 2006. In 2007, remainder of MFTCS routes added in state (~86).
Wisconsin Owl Survey Routes Used BBS routes to survey for owls. Approximately 91 routes exist in the state. Addition of new routes under consideration.

What is MAPS? The World Bird Population Institute (WBPI) investigates the reasons why bird populations change. The MAPS project is a part of the WBPI The Monitoring Avain Productivity Success (MAPS) studies birds while they nest in the spring. Birds are temporarily caught and then released. Scientists estimate the number of birds born and that survive into adulthood from this information Check out are Web site www.birdpop.com

Forest songbird conservation efforts should be directed at the largest tracts of forest such as the Smokies, Adirondaks, and the North Woods of Minnesota and Maine. John Terborgh, Why American Songbirds are Vanishing Scientific American - May 1992
Reasons/Objectives to Initiate Regional Monitoring Conduct off-road, habitat-specific monitoring Better our understanding of bird-habitat relationships Link population trends with habitat and landscape changes
Monitoring Design Proportional-stratified but restricted random design proportional with available habitat and restricted by logistics 10-minute point counts (subdivided by 3 and 5 min) with about 12 points per morning Experienced (tested for song ID and hearing ability) and trained (standardize field methods for 3-4 days) observers
Monitoring Design Continued All birds seen or heard are identified from point a concerted effort made to eliminate double-counting We use those individuals detected within 100 m in trend estimates - > 90 % of all observations > 1600 points censused annually
General Summary of Results 1991 to 2007 24,500 surveys 377,000 birds observed 175 species 73 species tested for trends in 2007
