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 Konza Long-term Ecological Research site (LTER) is located on a 3,847 ha tall-grass prairie reserve in Kansas. Konza LTER is divided into experimental watersheds, where each watershed is subjected to a combination of different fire and grazing intensities. Long-term monitoring of small mammal communities has been conducted on a...MORE
