The effect of mechanical canopy reduction on big sagebrush plant communities.

ABSTRACT: A major conservation challenge in the western United States is implementing management treatments that reduce fire risk, control for invasive species, and maintain herbaceous understories in big sagebrush ecosystems. Studies have found that mechanical treatment of big sagebrush can reduce fire risk and promote herbaceous understories, but a consensus on the long-term impacts of big sagebrush reduction remains unclear. We used a time series (20 years) of treated sites to understand the short- and long-term response of herbaceous plants and shrubs to mastication treatment in big sagebrush plant communities of south-central Colorado. We found that mastication to a height of 15 cm significantly reduced big sagebrush cover and increased perennial grass cover in the short term. The significant i
