Return to Conservation Biology Research on Birds

Green, J.C. 1985. A strategy for monitoring colonial waterbird species in Minnesota. Final report submitted to the Minnesota Department of Natural Resources. 8+ pp.


There are seventeen species of colonial waterbirds and over 600 known nesting sites in the state. A strategy for assessing species numbers and sites is presented that builds on present DNR activity in the field and in the central office where research and inter- and intra- agency coordination occurs. The monitoring strategy that is presented mixes both the species and the colony-site approach to surveying population trends in the birds. Recommendations are divided into three parts 1) Species and their site specific populations, with the state-listed species, 2) coordination with other agencies, and 3) suggestions for improving the accuracy and completeness of the colonial waterbird databases.
