Worldwide Species Action Plans

Short-eared Owl action planDespite widespread concern over declines in their abundance in many areas of North America, short-eared owls (Asio flammeus) are classified as G5 (secure) by the Nature Conservancy. The population status of this species is difficult to assess because they are nomadic and prone to annual fluctuations in numbers. Consequently, fixed-area census projects such as the Breeding Bird Survey do not adequately sample for short-eared owls. Most recent regional ornithological summaries (including state and provincial bird atlas projects) suggest that declines have occurred across the species range, including many areas in Region 2. Short-eared owls appear particularly sensitive to habitat loss and fragmentation, as they require relatively large tracts of grassland and are ground nesters, making them susceptible to the increased predation pressure that is typical within fragmented habitats and near rural developments. The development of conservation/management plans for short-eared owls has been hampered by the difficulty in accurately assessing their local and regional status, and by a lack of information on reproductive success. Although they are listed as a Bird of Conservation Concern by the U.S. Fish and Wildlife Service, as well as a Priority species within many state and regional Partners in Flight bird conservation plans, no research programs on the conservation status of short-eared owls are currently underway.
