Controlled or prescribed burns are common practice within nature reserves, mainly those with tallgrass prairies for the promotion of healthy plant growth. The goals of controlled burns are to increase the richness and diversity of plant species while impacting bloom times. At Litzsinger Road Ecology Center, burns are rotated yearly, and the close positioning of a north and south prairie allows for observation of these effects in a controlled, compact urban prairie. When a controlled burn occurs within a prairie system, it is typical to see changes in soil pH, increases in plant diversity, and longer bloom periods post-burn. Soil pH was different between the north and south prairie with the south prairie (post-burn) having a significantly higher pH. There was no significant difference of plant biodiversity pre and post controlled burn between the prairies. The north prairie had a statistically consistent higher number of blooming species over a 7-year period. Plant diversity measured within prairies also showed no evidence of change as a result of controlled burns. Within a group of focal species that span across both the north and south prairie, there was not a statistical difference in the bloom time lengths that presented themselves within each individual prairie or across all prairies. Further research is needed to understand the potential effect on microhabitats within each prairie. The controlled burns provide an opportunity for both research and in furthering the community education goals at Litzsinger Road Ecology Center.
