U.S. Army Corps of Engineers and Friends of the Wild Whoopers agree to assist in the recovery of endangered whooping cranes

Washington (July 10, 2018) – The U.S. Army Corps of Engineers (USACE) announced today the signing of a Memorandum of Understanding (MOU) with the Friends of the Wild Whoopers to assist in the recovery of endangered whooping cranes.

Per the MOU, USACE and Friends of the Wild Whoopers will jointly assess whooping crane migration stopover habitat at USACE water resources development projects. The assessments will be used by USACE to develop work plans that maintain and improve existing habitat and create additional habitat for this critically endangered bird as part of USACE Environmental Stewardship Program.

The whooping crane is one of the most endangered bird species in the world and is commonly seen as America’s symbol of conservation. Standing 5 feet tall with a wing span of 7 feet, it is the largest bird in North America.

Once fairly common, the species was reduced to just 16 birds by 1943. Market hunting and indiscriminate shooting along with habitat loss led to the decline of the species. Conservation efforts in the United States and Canada have seen the population increase to an estimated 431 birds in 2017.

This partnership is consistent with USACE’s responsibilities under the Endangered Species Act, which states that federal agencies may use their existing authorities to assist in the recovery of listed species.

Whitney Lake – Corps of Engineers’ Jewel for Whooping Cranes

by Pam Bates, Friends of the Wild Whoopers

Whooping Crane “stopover habitats” are increasing in importance on Corps of Engineer lakes according to Friends of the Wild Whoopers (FOTWW). Chester McConnell, FOTWW’s wildlife biologist explains that, “due to numerous land use changes on private lands, many wetlands and ponds that once served as Whooping Crane habitat are being drained and converted to other uses. So the large Corps of Engineer lakes are being used more and more by the cranes.”

Mostly, during migration Whooping Cranes “stopover” on lakes, natural wetlands and small ponds on private farms just to eat and rest overnight. Like humans on a long trip they just need a small place to briefly stop, feed, rest and then continue their journey. Importantly, Whoopers are compatible with other wildlife and briefly share their habitats. Ensuring that sufficient areas with the proper conditions as stopover sites are available is important for the survival of the species. Sensible practices applied by conservation interest can help reduce potential morality that occurs during migration.

FOTWW’s evaluations continue

FOTWW is continuing its evaluations of Corps lakes to identify areas with good Whooper habitat; habitats that need improvements; and areas that can be developed into good habitat. McConnell reasons that: “Corps lakes are federally owned and, if we can design projects that do not interfere with the Corps mission, then projects that help endangered Whooping Cranes should be authorized. Land cost are the major expense in such projects and using federal lands would eliminate that cost.”

Whitney Lake visited

McConnell visited Whitney Lake on April 12, 2018 to assess potential habitats for Whooping Cranes. Michael Champagne, USACE – Natural Resources Specialist, Fort Worth District made arrangements for our trip. Nickolus Mouthaan, Park Ranger led us on a tour of the lake to examine all potential places that could provide Whooping Crane “stopover habitats”. Brandon Mobley, Natural Resource Specialist, Fort Worth District Office participated in the tour. We discussed the natural resource objectives for Whitney Lake and needs for management (Figure 1).

Brandon Mobley, Natural Resource Specialist, Fort Worth District Office (on left) and Nickolus Mouthaan, Park Ranger (right) joined Chester McConnell, FOTWW during evaluation of “stopover habitats” on Whitney Lake. These men are standing on a broad expanse of grassland adjacent to a large lake inlet in H-10 Hunting Area. This is an excellent area to serve as “stopover habitat” for Whooping Cranes. Any cranes choosing to stopover here would have a wide glide path to land on the lake shore. The site is clear of obstructions and provides a gradual slope into the shallow water which is 2 to 10 inches deep in the roost area. Horizontal visibility around the roost site is good and allows the Whoopers to spot any predator that may be lurking nearby. Whoopers can feed on aquatic animal in the lake and forage on insects and grains in nearby fields.

About Whitney Lake

Whitney Lake was authorized by the Flood Control Acts of August 18, 1941 to provide flood control, hydroelectric power, water conservation for domestic and industrial uses, recreation and other beneficial water uses. The lake is located along the county lines of Hill and Bosque Counties on the main stem of the Brazos River. It encompasses a total of 49,820 acres and has a flood capacity of 1,372,400 acre-feet of water. At elevation 533 feet above Mean Sea Level (MSL), the normal pool level, the lake covers 23,560 acres and has a capacity of 627,100 acre feet.

Approximately 13,500 acres of government-owned land surrounding the lake are dedicated as natural areas. Primarily used for flood storage, this land is also intended for low impact public use with a minimum of facilities provided. The lake’s large size and diverse habitat support a number of native and introduced species of fish. The lake is a common stopping, resting and feeding area for Whooping Cranes, ducks, geese, shore birds and other waterfowl. This same land is primarily where FOTWW has recommended projects to increase benefits for Whooping Cranes (Figure 2).

Figure 2. This shore area on Whitney Lake is clear of obstructions and vegetation is short due partially to fluctuations in lake water levels. Any nearby predators could be easily detected. The water is shallow (2 to 10 inches) making it an excellent roost area. Overall it is an excellent Whooping Crane “stopover site”.
