Restoring Grasslands

Restoration ecology seeks to repair the diversity and dynamics of ecosystems degraded by human activities. Restoration studies in tallgrass prairie have become a core part of the Konza Prairie LTER (KNZ) program over the last decade, and are particularly timely because human activities have resulted in widespread loss and degradation of tallgrass prairie and other temperate grasslands.

Dr. Sara Baer
Grassland Restoration Studies: The Restoration Heterogeneity Experiment at Konza Prairie focuses on how soil resource availability and heterogeneity affects plant community structure and ecosystem processes in restored grasslands. The experiment includes plots with up to four levels of soil heterogeneity, which has resulted in the development of plant communities that vary in the number and abundance of species. 7/2000.
