Long-Term Ecological Research (LTER)/CDR020: Legume Competition at Cedar Creek Natural History Area

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

LTER/CDR020 [Summary adapted from the LTER Core Data Set Catalog]:

This experiment was established on top of subplots 24, 25, and 26 of
CDR018. Sheet metal was installed to divide the subplots into four
equal parts. The resulting 12 sub- subplots (4 per subplot = 12 per
plot) were planted according to the following treatments where LC =
Lespedeza capitata, AC = Amorpha canescens, PP = Petalostemum
purpureum, and SS = Schizachyrium scoparium:

1. LC seed on top of established SS
2. AC seed on top of established SS
3. no seed added to established SS
4. PP seed on top of established SS
5. AC seed vs SS seed
6. LC seed vs SS seed
7. PP seed vs SS seed
8. LC seed vs AC seed vs PP seed vs SS seed
9. AC seed
10. LC seed
11. bare ground (no seeds added)
12. PP seed

Proprietary limits: Investigators have priority over data for
five years, but are interested in collaboration for novel comparisons before
then.

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.
