Long-Term Ecological Research (LTER)/CDR022: Variations in Grasshopper Populations of an Old-Field Chronosequence at Cedar Creek

LTER - Long-Term Ecological Research Program/Cedar Creek Natural
History Area (CDR)

LTER/CDR022 [Summary adapted from the LTER Core Data Set Catalog]:

Grasshoppers are sampled monthly throughout the summer season by
sweep-sampling along four permanent transects in each of 19
successional old-fields, which were abandoned from agriculture between
1927 and 1983. These are the same transects along which small mammal
populations are sampled yearly and along which species composition of
vegetation is quantified periodically, but less often.

Proprietary limits: Access limited, but available with permission from
investigators, until subsets are published.

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.
