KAW LAKE, OK – Whooping Crane “Stopover Habitat”

by Pam Bates, Friends of the Wild Whoopers

So, as the New Year of 2019 arrives, what is Friends of the Wild Whoopers (FOTWW) doing for the Whooping Cranes? We are continuing our major project to protect and help manage “stopover habitat” for Whooping Cranes. Yep, not sexy but it is the most important need of the Aransas-Wood Buffalo population which is the last remaining wild whooping cranes on Earth.

The Aransas-Wood Buffalo wild Whooping Cranes can take care of themselves with two exceptions. They need man to help protect their habitat and for people not to shoot them.

FOTWW wildlife biologist Chester McConnell visited several lakes in Oklahoma recently to evaluate the potential for “stopover habitat” for migrating wild Whooping Cranes. One of these was Kaw Lake.

Our visit to Kaw Lake

Well, it rained for three days causing the lake to be in flood stage 8 feet above normal pool. So the high flood waters prevented a complete evaluation of potential “stopover’ habitat for the Whoopers. Not to be out done, FOTWW’s McConnell and Corps of Engineers Kaw Lake personnel did the best they could under the circumstances.

With the assistance of Hutch Todd, Kaw Lake Biologist and Peat Robinson, Kaw Lake Manager, FOTWW studied satellite photos made during past years when the lake pool was at normal pool level.. Using this process, we were pleased to learn about the three excellent potential sites that can be protected and managed to provide some important “stopover habitat” for Whooping Cranes.

There appears to be few stopover habitats for Whooping Cranes on Kaw Lake’s main pool but the upstream river that flows into the lake has many sandbars that have some good sites (Figures 1 and 2). The lake’s main pool shore areas are mostly steep with abundant trees growing close to the lake edge. These conditions do not lend themselves to stopover habitat for Whooping Cranes.

FOTWW’s McConnell advised that, “We did identify three areas with good potential stopover habitat. These are important and we encourage Kaw Lake personnel to protect and manage them carefully. The three stopover areas can provide diversity to stopover habitats for endangered Whooping Cranes and many waterfowl, wading birds, shorebirds and other wildlife species that need wetlands.”

Location of existing “stopover sites”

The photos (Figs. 1 and 2) illustrate three potential “stopover areas” on Kaw Lake and upstream where endangered Whooping Cranes can rest, forage and roost during their two annual migrations. The size and configuration of these stopover areas vary with the levels of lake water. When the photos in this report were taken, water levels were “normal”. Flight glide paths to the shore areas are available from different directions for approaching cranes. The shore areas at the three sites need some management to clear bushes, trees and other obstructions. Horizontal visibility from the shore and water roost sites allows Whooping Cranes to detect predators that may be in the area. The shore and lake edge at the three sites has some gradual slopes and some water depths of 2 to 10 inches available during “normal” lake water levels. The water is clear and supports abundant aquatic life. Foraging is available on USACE property and in numerous nearby agriculture fields. In addition there are wild foods in adjacent managed grasslands and wetlands that provide an abundance of insects, wild seeds and other wild food.

Recommendations

FOTWW recommended that the Corps of Engineers and OWDC managers should focus on protecting all potential stopover sites that we identified. These areas currently appear to have good “stopover habitats” with safe roosting features and nearby agricultural landscapes that provide foraging opportunities.

FOTWW sincerely appreciates the interest and cooperation of Kaw Lake and Tulsa District personnel and other officials of the Corps of Engineers who cooperated with us and provided documents that assisted in our evaluation. And a special thanks to David Hoover, USACE who arranged our field trips to four lakes in Oklahoma.

Figure 2. The sandbars in this photo are several river miles upstream of the larger sandbars in Figure 3. Marker number “1”is a wide sandbar clear of vegetation. Whooping Cranes could land here and locate shallow water available where they could roost. The sandbar at marker number “2” can also be developed into another good stopover site if the shrubs and trees identified by the arrows are cleared by cutting, burning or spraying with an appropriate herbicide.
KAW LAKE, OKLAHOMA
Figure 3. The sandbars at the head of Kaw Lake can serve as an excellent “stopover habitat” for Whooping Cranes during their migrations. The island formed as upstream banks of the Arkansas River eroded and the sand washed downstream until it met with slack waters of the lake. At this point the sand dropped out of the river water column to form the island. These islands will need management to control growth of trees and shrubs. These can be controlled by spraying with appropriate herbicides or mechanical means.

Future Whooping Crane Island Habitat on Canton Lake, Oklahoma

by Chester McConnell, Friends of the Wild Whoopers

Whooping Cranes are facing continuing threats to their habitats as time goes by. During their 2,500 mile migration from their Canadian nesting area to their Texas wintering habitat 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.

Dwindling wetlands

Private lands have traditionally provided most of the “stopover habitats” but many of these properties are being more intensively managed and face various forms of development. And some wetlands are becoming dryer due to global warming. So, what can we do to help? Friends of the Wild Whoopers (FOTWW) contends that lands and waters on U.S. Army Corps of Engineers (USACE) lakes, military base wetlands and Indian Reservations within the migration corridor can provide much needed relief. Many 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. Likewise Whooping Cranes are compatible with other wildlife…

FOTWW has completed habitat evaluations on 32 military facilities, 8 Indian Reservations and 21 USACE lakes within the wild Whooping Crane migration corridor. Some of these properties currently have suitable stopover wetland habitats while other areas could be enhanced with minor work.

USACE lakes within the 6 state migration corridor are likely to become even more important to Whooping Cranes in the near future because of their locations and quality of “stopover habitats”. Canton Lake and others that are located in the Whooping Crane migration corridor can be especially valuable.

Canton Lake, Oklahoma

Canton Lake contains 7,910 acres of surface water and 14,861 acres of public hunting land that is managed by the Oklahoma Department of Wildlife Conservation (ODWC). This area is open year round, except for the migratory bird refuge which is closed annually from 15 October to 15 February. Canton Lake’s purpose is to provide flood risk management, water supply, fish and wildlife conservation and recreation.  Since its impoundment more than 60 years ago, it has been enjoyed by millions of people. The lake offers extensive opportunity for outdoor recreation activities.

FOTWW is aware that Canton Lake, has been used by Whooping Cranes and we expect that to continue and increase. Both USACE and ODWC personnel have observed Whooping Cranes on the lake several times.

As FOTWW Wildlife Biologist, I visited Canton Lake on October 10, 2018 to assess potential “stopover habitats” for Whooping Cranes. David Hoover, Conservation Biologist, Kansas City, MO, USACE made arrangements for our trip. George Mayfield, Assistant Lake Manager and Chase Kokojan, ODWC participated in the lake stopover habitat evaluation. After discussing the natural resource objectives for Canton Lake we made a tour of the lake property by vehicle to examine the most likely places that would provide Whooping Crane “stopover habitats”. We identified several potential stopover habitat areas one of which is described below.

Canton Lake

Additional treatments may be necessary to maintain the vegetation at a height height of 2 feet or less. Whooping Cranes require areas where they can readily observe predators such as coyotes and bobcats.

 

Canton Lake
Figure 2. This photo displays the land base at the boat ramp, the cattail and phragmites plants and the island (same as in Fig. 1) in the background. If managed properly the island and shore area can become excellent “stopover habitat” for Whooping Cranes, waterfowl and other wild creatures. Vegetation in the area can be treated with herbicide and allowed to dry. After the dead vegetation is dried, it can be burned. A second treatment may be necessary to get the areas described in good condition.

DESCIPTION OF POTENTIAL “STOPOVER HABITATS”:

The photos (Figs.1 and 2 are potential “stopover habitats” for endangered Whooping Cranes to rest and roost. The island is located in an isolated location and not near frequently travel roads or power lines. The size and configuration of the wetland area varies with the levels of lake water. When the photos in this report were taken, water levels were approximately 1.5 feet higher than “normal”. Flight glide paths to the shore areas are available from different directions for approaching cranes. The shore areas and island are essentially clear of bushes and trees. Horizontal visibility from the island and shore roost sites, if properly managed, would allow Whooping Cranes to detect any predators that may be in the area. The slope of the shore and lake edge is gradual and some water depths of 2 to 10 inches would be available during “normal” lake water levels. There is little emergent or submerged vegetation in lake at these roost sites. The locations are 200 or more yards from human development or disturbance such as power lines. Hundreds of acres of foraging areas are located on ODWC wildlife food plots and in nearby agriculture fields. In addition there are wild foods in adjacent managed grasslands and wetlands that provide an abundance of insects, wild seeds and other wild food.

 

FOTWW appreciates all involved with making preparations for a productive and enjoyable visit.

Corps of Engineer lakes in Oklahoma being evaluated for Whooping Crane “stopover habitats”

By Pam Bates, Friends of the Wild Whoopers

Whooping Cranes migrate 2,500 miles two times each year between their nesting area in Wood Buffalo National Park, Canada and their Aransas Wildlife Refuge winter habitat on the Texas coast. During these migrations they must stop to rest and feed 15 to 30 times. Friends of the Wild Whoopers (FOTWW) is searching for areas to provide these essential “stopover habitats”. Stopover habitats are equally as important as nesting and winter habitats.

Fort Supply Lake

Fort Supply Lake in northwest Oklahoma is one of four Corps of Engineer (COE) Lakes that have recently been evaluated to determine if they have any existing or potential “stopover habitat” for migrating Whooping Cranes.  FOTWW visited the four lakes as part of its continuing efforts to encourage protection and management of decreasing habitat for migrating Whooping Cranes.

Despite heavy rainfall, flooding and high water levels in three lakes FOTWW‘s wildlife Biologist Chester McConnell explained that: “Our evaluation team continued towork in the challenging conditions. Fortunately COE and Oklahoma Wildlife Division (ODWC) personnel accompanied me and they were well informed about the lake’s habitats. So, together, we successfully identified some good stopover habitat sites.” Fort Supply Lake is just one of many COE lakes that FOTWW has, and will be evaluating. The Operation Management Plan FY 2014 thru 2018 covers information for the COE area of primary management responsibility. The “Wildlife Management/Hunting program” is described in a separate document prepared by ODWC. The lake was authorized under the Flood Control Act approved June 22, 1936. Construction of the lake was begun in October 1938 and completed in August 1942.  There is a total of 9,899 acres of project land and water. The lake covers 1,786 surface acres of open water. A total of 8,079 acres are used for wildlife management, recreation and project operations. Although the primary mission is flood control, important secondary benefits are water supply, recreation, and natural resource management. Importantly one of the natural resources needing the lake is the only wild population of wild Whooping Cranes remaining on earth.

The short grass, shallow water and absence of trees and bushes in this photo cause it to be suitable for Whooping Crane “stopover habitat” during normal water levels. During our evaluation, abundant rain (8+ inches) caused the lake depth to be deeper than normal. Water depths vary occasionally due to abundant rain and long drought periods. Importantly, due to various shore configurations, when one area of a lake is not suitable, some other area of the lake will likely be suitable.

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.
