2
Objective

• Describe proposed avian monitoring effort for
  Upper Snake Headwaters Subbasin, Idaho

3
Headwaters w/ Special Habitats

• Grays Lake NWR inviolate sanctuary
• Market Lake WMA Former Flood Plain
• Tex Creek WMA BOR ACoE Mitigation lands
• Deer Parks BPA Mitigation lands
• South Fork Lands Conservation Easements fee
  purchase

4
South Fork of the Snake River
5
Whats Missing??

• Consistent monitoring program across the subbasin
  to assess
• Biodiversity
• Population trends
• Management and other impacts
• Environmental Health

6
Proposal

• Establish aggressive monitoring program for
  passerine birds in Snake River Headwaters Subbasin

7
Where ??
Deer Parks
Heise
Market Lake
Black Canyon
Tex Creek
Grays Lake
8
Why Avian Monitoring

• No consistent monitoring program throughout
  Headwaters
• Birds considered excellent barometer for
  terrestrial habitat environmental health
• Birds considered excellent indicator of
  terrestrial biodiversity
• Population metrics (e.g. species richness,
  abundance, etc) easily measured

9
Traditional Bird Survey

• Point Counts (e.g. Breeding Bird Surveys)
• Continuous Counts (e.g. Christmas Counts)

10
Traditional Data

• Snapshot sampling
• Presence/absence information
• Species richness
• Relative abundance
• Species diversity
• NO Vital Metrics
• Productivity
• Survivorship

MAPS is . . .

• Constant effort avian capture and release program
• Modeled after British Constant Effort Sites
  Scheme

13
MAPS is . . .

• Nationwide program coordinated by the Institute
  for Bird Populations

14
MAPS is . . .

• Used by . . .
• USFS as part of Partners in Flight Program
• National Park Service Vital Signs Program
• Department of Defense Legacy Resource Management
  Program
• Over 450 MAPS Stations in US

15
Continent Wide Program !!
16
MAPS Objectives

• Annual indices of adult population size
  post-fledging productivity
• Annual estimates of
• Adult survival rate
• Population size
• Proportion of residents in population
• Recruitment into the population

17
MAPS Protocol

• Breeding Season only!
• Constant effort
• Consistent seasonal start end times
• Consistent sampling time/sampling day
• Consistent interval between sampling
• Standard elements
• Standard size mist nets 12 m, 4 tier, 30-mm
  mesh
• Standard number (10) of mist nets/station
• Standard density (10/8 ha)

18
Expected Results

• Measure of biodiversity
• Assessment of productivity survivorship
• Sink vs source evaluation
• Monitoring of population stability/changes
• Measure of management or other impacts
• Early warning from downward trends
• Contributor to MAPS nation-wide program
