Randomized trial tests the effects of prescribed fires on forage quality in grassland ecosystems, suggesting benefits for wildlife management.

The study aims to assess how prescribed fire during dormant seasons influences forage quality across different grassland ecosystems.
Conducted 152 independent small-plot prescribed burns across 36 sites in Wyoming and South Dakota.
Examined the effects of ecosystem type, burn seasonality, and fuel characteristics on forage quality.
Analyzed outcomes for northern mixed-grass prairie and sagebrush grassland ecotone.
Fall prescribed fires significantly improved forage quality parameters during the first growing season post-burn.
Energy benefits of fall fires persisted into the second growing season.
No critical drop in forage quality for ruminants was observed, indicating robust nutritional quality.

Porensky et al. (2026) studied this question.
