ISS Focal Site (PRISM) Background Information

The "Program for Regional and International Shorebird Monitoring” (PRISM) is a focused program designed to (1) estimate the size of breeding populations of 74 shorebird taxa in North America; (2) describe shorebirds’ distribution, abundance, and habitat relationships; (3) monitor trends in shorebird population size; (4) monitor shorebird numbers at stopover locations, and; (5) assist local managers in meeting their shorebird conservation goals (Bart et al. 2002). It has three main components: arctic and boreal breeding surveys, temperate breeding surveys, temperate non-breeding surveys, and neotropical surveys.  In the lower 48 U.S. states we are tasked with the temperate non-breeding surveys and temperate breeding surveys.


PRISM is being implemented by a Canada-U.S. Shorebird Monitoring and Assessment Committee formed in 2001 by the Canadian Shorebird Working Group and the U.S. Shorebird Council.  PRISM is based on the shorebird conservation plans completed in Canada and the U.S. and provides a single blueprint for implementing both of these plans. Surveys during the nonbreeding period monitor use at stopover locations. The ISS was identified as an ideal program to assist with these surveys. ISS Focal Sites, or PRISM sites, were identified by refuge managers, federal and state biologists and ISS surveyors. The results from surveys at these sites are meant to have an 80% power to detect a 50% decline occurring during 20 years.
