Long-Term Ecological Research (LTER)/CDR021: Invasion of Old Fields by Trees at Cedar Creek Natural History Area
Listed in NASA Earthdata CMR
LTER - Long-Term Ecological Research Program/Cedar Creek Natural History Area (CDR) LTER/CDR021 [Summary adapted from the LTER Core Data Set Catalog]: Replicated deer exclosures (n = 3) were built at the margins of two old fields.
Description
All trees in controls and exclosures were tagged, mapped, examined for browsing damage, and measured annually (maximum height) from 1983 through 1989. Pocket gopher mounds were mapped on these plots every year from 1986 to 1989.
Future sampling will be done at variable intervals, probably every 3-5 years. Successive 20-m strips of a field cultivated in rye have been abandoned each year since 1977. In 1988, trees were tagged, mapped, and measured (maximum height) in all strips.

Trees were remeasured and additional trees were tagged in 1989. These plots will be sampled at variable intervals, probably every 2-3 years. The Cedar Creek Natural History Area (CCNHA) is a 2200 hectare experimental ecological reserve operated by the University of Minnesota in cooperation with the Minnesota Academy of Sciences.
CCNHA is located in Anoka and Isanti Counties north of Minneapolis/St. Paul. The site was established in 1940, was designated a National Natural Landmark by the National Park Service in 1975.
In 1977 it was included as an Experimental Ecology Reserve in a proposed network, and in 1982 it was one of 11 sites in the U.S. selected by the National Science Foundation for funding of LTER. Information about LTER is also available at 'lternet.edu/'
