The effects of management practices on grassland birds—Short-eared Owl (Asio flammeus)

December 20, 2021

The key to Short-eared Owl (Asio flammeus) management is providing large grasslands and wetlands, particularly those that can support high densities of voles (Microtus species). Short-eared Owls have been reported to use habitats with 30–90 centimeters (cm) average vegetation height, 7–47 cm visual obstruction reading, 31–85 percent grass cover, 8–26 percent forb cover, less than 18 percent shrub cover, 43 percent litter cover, and 1–2 cm litter depth.
