Monitoring for Tomorrow’s Habitat-Approach
• Statewide
• Comprehensive
• Focus on key habitats
• Identify a common set of indicators• Integrate existing information
• Fill monitoring gaps
• Amount
• Quality
• Associated species in greatest conservation need
• Prairies, surrogate grasslands, savannas
• Key river reaches
• Lakeshores
• Wetlands
• Upland & lowland coniferous forest
KEY HABITATS
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 Survey1968-1971 (archives) & 1972-2006 (digital)
May 1-25 (focus on breeding mallards in Prairie and Transition zones)
115 aerial transects (0.25-mi wide)
Stratified sampling design based on density of wetlands and lakes >4 ha (1968 data)
Double sampling (14 air-ground segments) to estimate visibility corrections
Estimated total ducks (by species) and May ponds in sampling frame

Statewide Bald Eagle Surveys
• Statewide surveys every 5 years: 2000 & 2005 completed
• In 2005, added a random plot survey to known nest survey methodology
Northern Goshawk Project 2003-2005
– 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 (MLMP) 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 (LOTW) area is the only remaining breeding site for piping plovers in Minnesota.
– Nesting common terns are also assessed annually

MCBS Statewide 1988-2006breeding season bird surveys
• 69 counties completed
– +5 partially completed
• 5,431 survey locations
– 4,454 point counts
– 977 species lists
• 73,000+ bird records
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

Wildlife staff and volunteers conduct three kinds of bird surveys annually (28 years of data):
1) Bike Trail Surveys
2) Habitat Transects
3) Woodland Point Counts
Also some special purpose surveys suchas volunteer raptor search, periodic rail counts, osprey monitoring
Breeding Bird Surveyhttp://www.mbr-pwrc.usgs.gov/bbs
• 3,100+ routes across US and Canada (random – systematic)
• ~80 roadside routes in Minnesota
• Experienced volunteers
• 24.5 mile routes, 3 min stops every 0.5 mile
House Finch
• Western species• Introduced on Long Island in 1940• Rapid growth in numbers with expanding
geographic range in Eastern US• Expansion detrimental to native Purple
Finch
Minnesota’s Forest Bird Diversity Initiative
• Funded by Legislative Commission for Minnesota Resources through Minnesota Department of Natural Resources
• Program Leader –– Lee Pfannmuller– Head, Ecological
Services Division, MN DNR
“Forest songbird conservationefforts should be directed at…the largest tracts of forest suchas the Smokies, Adirondaks, and the North Woods of Minnesotaand Maine.”
John Terborgh, “Why AmericanSongbirds 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

Ovenbird Breeding Habitat
• Mature deciduous and coniferous forest
• Most abundant in forests with an open understory
• Long-distance migrant
White-throated Sparrow breeding habitat
• Recent 3-20 year old logged areas
• Black spruce/tamarack forested wetlands
• Requires thick coniferous understory
• Species over-winters in southern United States
