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 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

Statewide Bald Eagle Surveys

• Statewide surveys every 5 years:

2000 & 2005 completed

Statewide Bald Eagle SurveyNumber 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

SurveyBreeding bird surveys

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

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

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

Where?

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

Breeding Bird Atlas

• 5 Years to complete, 2008 = Year 1

• Will survey all townships in MN and record

all breeding bird activity

• ANYONE can participate

“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
