Kessler Farm Field Laboratory is a 350 acre tract of mixed grass prairie donated to the University of Oklahoma for research and teaching in environmental studies. This diverse landscape has mixed and tall grass prairie, riparian woodlands, Finn Creek and several ponds. In addition, it is the home to a number of long-term meteorological and biological experiments.
KFFL welcomes you, your students, your organization or your laboratory to visit and to use our facilities! On this web site you will find more detailed descriptions of the opportunities available on KFFL, as well as our rules for use. KFFL represents a truly great opportunity for environmental studies in the south central Great Plains!

Global Warming Studies at KFFL
Two experiments related to global warming have been conducted on KFFL. The first, long-term experiment consists of 6 sets of paired plots, half of which have been warmed 2 oC above ambient since November, 1999. Nested in this design are clipped plots that mimic one of the dominant land uses of the KFFL region, hay mowing.
These studies have shown that these grassland systems are remarkably resilient, with little change in community structure as a result of warming. However, a number of microbial processes have shown significant changes, with increased rates of decomposition, and alterations in rates of soil respiration. Litter decomposition was highest in the unclipped warmed and clipped plots. Clipped plots are significantly drier, slowing rates of microbial processes. [ more ]
