Long-Term Ecological Research (LTER)/CDR023: Variations in Small Mammal Populations of Successional Old Fields at Cedar Creek

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

LTER/CDR023 [Summary adapted from the LTER Core Data Set Catalog]:

Small mammals are sampled each summer in late August and early
September by snap-trapping along four permanent transects in each of
19 old-fields. Six species occur regularly in these samples:
Peromyscus maniculatus, Microtus pennsylvanicus, Sorex cinereus,
Blarina brevicauda, Zapus hudsonius, and Mus musculus. Pocket gopher
disturbance has been estimated along these transects less frequently,
but is now a regular part of the annual survey. Grasshoppers,
vegetation, and soils are also sampled regularly along these
transects.

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.
