Shaffer 2021 <p>The key to Grasshopper Sparrow (<i>Ammodramus savannarum</i>) management is providing large areas of contiguous grassland of intermediate height with moderately deep litter and low shrub density. Grasshopper Sparrows have been reported to use habitats with 8–166 centimeters (cm) average vegetation height, 4–80 cm visual obstruction reading, 12–95 percent grass cover, 4–40 percent forb cover, less than 35 percent shrub cover, less than or equal to (≤) 38 percent bare ground, 5–61 percent litter cover, and ≤9 cm litter depth.</p> application/pdf 10.3133/pp1842GG en U.S. Geological Survey The effects of management practices on grassland birds—Grasshopper Sparrow (<i>Ammodramus savannarum</i>) reports
