The Effects of Management Practices on Grassland Birds—Savannah Sparrow (Passerculus sandwichensis)

Professional Paper 1842-FF
By: , and 



Keys to Savannah Sparrow (Passerculus sandwichensis) management are providing extensive grasslands of intermediate height and density with a well-developed litter layer, controlling succession, and protecting nesting habitat from disturbance during the breeding season. Savannah Sparrows have been reported to use habitats with 11–190 centimeters (cm) average vegetation height, 4–50 cm visual obstruction reading (VOR), 15–66 percent grass cover, 4–45 percent forb cover, less than (<) 29 percent shrub cover, <38 percent bare ground, 10–63 percent litter cover, and less than or equal to (≤) 21 cm litter depth.
