Rainfall intercept shelters were established on Kentucky bluegrass invaded loamy ecological sites in pastures 13, 14, and 15 of the USDA-ARS Northern Great Plains Research Laboratory. At three different blocks, nine 2m2 plots were established in 2017.
Each 2m2 plot is divided in half and half of the plot is burned every 2 years.
We hypothesize that:
Decreased precipitation will reduce the relative abundance of Kentucky bluegrass.
Burning will decrease the relative abundance of Kentucky bluegrass.
Increased stress through burning and simulated drought will decrease Kentucky bluegrass abundance and increase native species richness.
