Friends of the Wild Whoopers (FOTWW) is continuing to work on its joint Whooping Crane “stopover habitat” with the U.S. Army Corps of Engineers (USACE). The project involves the 7 state migration corridor within in the states of Texas, Oklahoma, Kansas, Nebraska, South Dakota, North Dakota and Montana. FOTWW has completed its evaluation of Lake Sharpe properties in South Dakota and our Wildlife Biologist Chester McConnell provided a summary of their findings and recommendations.
McConnell emphasized that FOTWW appreciated USACE personnel who accompanied us on our field evaluation. “They were well informed about the lake’s abundant habitats and management needs. So, together, we successfully identified many stopover habitats that needed only minor management” explained McConnell.”
Habitat threats continue
Today Whooping Cranes are facing continuing threats to their habitats. During their two 2,500 miles migration from their Canadian nesting habitats and their winter habitats on the Texas coast they must stop 15 to 30 times to rest and feed. Secure stopover habitats are needed throughout the migration corridor approximately every 25 miles. And more secure wintering habitats are needed along the Texas coast near the Aransas National Wildlife Refuge. Currently about half of the population winters off the Aransas National Wildlife Refuge where they are not as safe. Continuous development along the coast is taking a serious toll on habitat.
FOTWW believes that the wild Whooping Cranes in the Aransas/Wood Buffalo population are capable of taking care of themselves with two exceptions. They need (1) humans to protect their habitats and (2) humans to stop shooting them. We firmly believe that the USACE can do much to protect and manage many “stopover habitats” within the migration corridor wetland habitats while other areas could be enhanced with minor, low cost work.
The USACE and FOTWW operate under a Memorandum of Understanding that allows FOTWW to focus on Whooping Crane habitat assessment and management recommendations on lands under USACE jurisdiction. We first need to determine if any suitable areas could be managed, or appropriately developed, to provide stopover habitats for Whooping Cranes. The next step would be to work to encourage appropriate management.
McConnell explained that “we have learned that USACE lakes within the 7 state migration corridor are very valuable to migrating Whooping Cranes. And we believe they are likely to become even more important to Whooping Cranes in the near future because of their locations and quality of “stopover habitats”. Lake Sharpe and others that are located in the Whooping Crane migration corridor can be especially valuable. As the crane population increases the migration corridor may also expand in width.
Lake Sharpe is just one of the 35 USACE lakes that FOTWW has evaluated. We are aware that Whooping Cranes have visited Lake Sharpe and we expect that to continue and increase. United States Geological Survey personnel used location data acquired from 58 unique individuals fitted with platform transmitting terminals that collected global position system locations. Radio-tagged birds provided 2,158 stopover sites over 10 migrations and 5 years (2010–14) using individual Whooping Cranes. Whooping Cranes were also observed in the vicinity of Lake Sharpe property several times.
McConnell explained that during migration Whooping Cranes often stop over on private lands, wildlife areas, lakes and some military bases. However, many private lands are being more intensively managed and face various forms of development. And some wetlands are becoming dryer due to global warming. FOTWW contends that lands and waters on USACE, military bases and Indian Reservations within the migration corridor can provide much needed relief. Some of these lands can be developed and/or managed to provide more stopover habitats for endangered Whooping Cranes. Importantly, habitats for the cranes also benefit many other species of wildlife and fish. So Whooping Cranes are compatible with other wildlife species using the same habitats.
The most expensive part of establishing or improving habitat is land cost. If projects can be accomplished on government lands and Indian Reservations, the cost would be relatively minimal. Importantly any habitat projects deemed to be incompatible with the mission of the agencies involved would not be considered by FOTWW.
FOTWW has completed habitat evaluations on 32 military facilities, 8 Indian Reservations and 35 USACE lakes within the wild Whooping Crane migration corridor. Most of these properties currently have some suitable stopover habitats but there is much more potential explained McConnell.
