Abundant rainfall and plenty of heat made this summer an excellent season for prairie development. The prairie was mowed twice, once at the end of May and the other in the middle of July. This proved to be helpful with controlling queen anne's lace and other assorted non-natives, however it appears that smooth brome is going to continue to be a problem and will be a threat to the growth of warm season plants in the future.
The experimental wedge shaped plot is now in it's third growing season and looks amazing. If the rest of the prairie develops as well as this did in the next two years I'll be pretty impressed. Photo below is of the experimental wedge - October. The gold/copper hues of the native grasses are much more attractive than the dead look of the remaining cool season fields.
