Experiment 012

Effect of Fire Frequency on Prairie Grassland Vegetation

oak savanna burning experimental plots

The purpose of this experiment, begun in 1983 by Johannes Knops, is to determine what effect different fire frequencies have on grassland vegetation. This experiment is being conducted in field B. There are 4 different burn treatments:

  1. plots burned every year
  2. plots burned every other year
  3. controls which are not burned
  4. plots burned every fourth year

There are 6 replicates of each treatment which were randomly assigned to the 24 plots. Plots are 8 by 8 meters and are placed in a 3 by 8 grid with 2 meter walkways. Plots are marked with colored rebar at each corner.
