Title A comprehensive monitoring program for colonial waterbirds

Project Description Colonial waterbirds are biological indicators of the health and diversity of coastal and wetland

ecosystems. Throughout the world, the destruction of freshwater wetlands, destruction and

degradation of coastal ecosystems, depletion of the forage base in freshwater, coastal, and

marine ecosystems, contaminants, sea level rise, and human disturbance threaten colonial

waterbirds (Parnell et al. 1988). A coordinated monitoring program with standardized monitoring

protocol and broad geographic coverage will lead to the collection of critical information for

long-term conservation planning. One part of this monitoring effort, a centralized database

incorporated into the National Bird Population Data Center, will integrate information on the status,

trends, and biogeography of waterbirds across regions, provinces, and states, and will facilitate a

coordinated response to conserve these birds throughout their ranges. Furthermore, a centralized

database will support analyses of long-term trends of waterbirds and document population status

and shifts in distribution and habitat use; this information will help (1) document the present and

future problems facing colonial waterbirds and, (2) better define the management actions

necessary to support their long-term conservation.
