The North American Breeding Bird Survey (1966-present) consists of data on the diversity and abundance of summer bird assemblages at approximately 5000 sites across the continental U.S. and Canada. Sampling began in 1966 and many sites have time-series that are at least 20 years long.MORE
The FIADB contains community information for sites throughout forested lands of the US and its territories. There are three stages of sampling, which affects the type of data available for any given site: Phase 1 consists of remote sensing for stratification and identification of forested land. Phase 2 [Forest Inventory...MORE
Over 22 years, Alwyn H. Gentry collected data from 226 sites on six continents. Gentry and his collaborators collected all plants with stem diameters equal to or exceeding 2.5 cm diameter at breast height (dbh) along ten 2 x 50 m transects, totaling 0.1 hectare at each site. Ecological Level:...MORE
