资源简介：
Northern Prairie has a long history of studying nest success of upland nesting
ducks. Over the years, we have developed standardized procedures for collecting
and analyzing these types of data. Data forms and instruction manuals developed
by the Center are used widely by biologists throughout the northern Great
Plains and elsewhere. Extensive use of standardized procedures led to a
cooperative effort among Federal, State, Private, and other Non-Government
Organizations that has allowed us to compile the Nest File, a data base of more
than 75,000 duck nests spanning 30+ years in the northern Great Plains.
