2021 Update: Hesperostipa fire and flowering in remnants

During late summer 2021, we began collecting data in remnant patches of prairie to quantify fire effects on the reproduction of Porcupine grass (Hesperostipa spartea). We visited 209 random points established during the summer across 17 remnant patches and counted the number of flowering Hesperostipa culms rooted within 1 m of the random point. Across the 209 plots, we counted 1159 culms. The highest density we observed was 101 culms in one plot at Landfill East. In addition to counting culms, we also counted the number of fruits produced by culms in each plot. The plot with 101 culms at Landfill East also held the record for fruit count at 523!
