MAPS IN THE UPPER SNAKE HEADWATERS SUBBASIN Tim Reynolds, Ph.D. TREC, Inc. January 23, 2002

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

Headwaters w/ Special Habitats Grays Lake NWR – inviolate sanctuary Grays Lake NWR – inviolate sanctuary Market Lake WMA – Former Flood Plain Market Lake WMA – Former Flood Plain Tex Creek WMA – BOR & ACoE Mitigation lands Tex Creek WMA – BOR & ACoE Mitigation lands Deer Parks – BPA Mitigation lands Deer Parks – BPA Mitigation lands South Fork Lands – Conservation Easements & fee purchase South Fork Lands – Conservation Easements & fee purchase

South Fork of the Snake River

Whats Missing?? Consistent monitoring program across the subbasin to assess: Consistent monitoring program across the subbasin to assess: Biodiversity Biodiversity Population trends Population trends Management and other impacts Management and other impacts Environmental Health Environmental Health

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

Where ?? Grays Lake Deer Parks Market Lake Tex Creek Black Canyon Heise

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

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

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

M onitoring A vian P roductivity & S urvivorship What is MAPS?

MAPS is... Constant effort avian capture and release program Constant effort avian capture and release program Modeled after British Constant Effort Sites Scheme Modeled after British Constant Effort Sites Scheme

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

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

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