From: Dormant-Season Fire Inhibits Sixweeks Fescue and Enhances Forage Production in Shortgrass Steppe
Least squares means ± standard error of the mean for autumn fire treatment × year for (a) six-weeks fescue (g m−2), (b) C4 perennial grass (g m−2), and (c) forage (g m−2) biomass collected in late summer from 2007 to 2016. Means with different subscripts differ (P < 0.05). Red arrows point to measurements taken in the growing season following burning. The rain cloud is above the year when precipitation patterns prevented burning.
