Integrated Waterbird Management
& Monitoring Program
USGS Patuxent, Laurel, Maryland
What is the IWMM Program?
The integration of management, data and decisions at the local, regional and flyway scale.
Problem:difficulty of managing wetlands for a wide range of species, in changing landscapes
Where did IWMM come from?
“What is the best way to manage this wetland?”
“What is this wetlands highest and greatest contribution to flyway conservation efforts?”
“How should this wetland be managed to optimize stopover quality?”
“How does the bird use and management of this wetland compare to other wetland units?”
“How do I allocate funds among wetland units in an informed and transparent way?”
“Which wetlands are important to waterfowl …. shorebirds ….. wading birds?”
“If I allocate more funds and staff which areas will significantly increase this region’s contribution to flyway conservation efforts?”
“Where, when and in what numbers are migratory birds using stopover habitats?”
“Where in a flyway should we focus acquisition and restoration activities?”
“Are there important sites within this flyway that are not protected?”
Flyway: when, where, how much habitat?
Regional: optimal allocation of funds
Local: optimal management strategies
Linking Management Decisions with Data
Identify Critical Waterbird Sites
Determine Optimal Wetland Management Scenario
State / Region
Determine Funding Distribution
Components include GIS data layers and biological parameters (from literature)
Path 1 = 1706 Birds
Path 2 = 530 Birds
Regional and local allocation: cost effectiveness
Bird Use (B)
AH = Available Habitat
B= Contribution of Bird-Days
Vegetation Surveys twice per season
e.g. site 3 is a diving duck site – flyway model might suggest it would contribute more as a dabbler site
Management increases habitat-value index for site from 40 to 60
Bird-use days/ha (dabblers) predicted to increase from 40/ha to 250/ha
∆ buds on a 10 ha site = 2,100
∆ buds on a 200 ha site = 42,000
