Title: Long-Term Ecological Research (LTER)/CDR024: Plant Community and Soil Development During Secondary Succession at Cedar Creek
LTER - Long-Term Ecological Research Program/Cedar Creek Natural
History Area (CDR)
LTER/CDR024 [Summary adapted from the LTER Core Data Set Catalog]:
Major herbivores were excluded from fifteen 12 m x 12 m plots in a
newly abandoned old-field. Main treatments include gopher removals,
all large vertebrate removals, and controls. Smaller (3 m x 12 m)
grasshopper removals are nested within main treatments. Gopher
distur-bance will be quantified throughout the summer season. Soils
(including N mineralization) and vegetation will be sampled regularly
on 100-point grids within each plot.
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.
