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.

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.

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.

Fort Supply Lake, Oklahoma Figure 2. 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.

Whooping Crane “Stopover Ponds/Wetlands” Plans

By Chester McConnell, Friends of the Wild Whoopers

Landowners and other land managers often contact Friends of the Wild Whoopers wanting to know how they can help endangered wild Whooping Cranes. Normally we discuss needs by phone or email. To simplify the process we have developed a brochure to provide information concerning one major and growing need.

This need is to properly manage existing ponds/wetlands or develop new ponds/wetlands so that they will attract Whooping Cranes. These amazing birds migrate 2,500 miles two times each year between their Canadian nesting grounds and their winter habitats on the Texas coast. During these long migrations they must stop to rest about 10 to 15 times.

While there are about a dozen prime stopover sites on wildlife refuges, migrating Whoopers mostly stopover on small ponds/wetlands on private farms just to rest overnight. Over the years thousands of stopover areas have been destroyed due to changes in land use. As the Whooper population continues to increase there is an increasing need for more stopover sites on private lands. The focus for these ponds/wetlands is in North Dakota, South Dakota, Nebraska, Kansas, Oklahoma and Texas.

If you own land would you share a small amount with Whooping Cranes? And if you are not a landowner, possibly you could partner with one to help prepare a stopover pond. Ponds can be about any size from one-third acre and larger. The USDA Natural Resources Conservation Service (NRCS) has cost share funding and technical support that will provide dollars to landowners needing assistance. It is also important to know that ponds developed or managed for Whooping Cranes also provide habitats for many other kinds of fish and wildlife.

Whooping Crane “Stopover Ponds/Wetlands” Plans

Interested persons are invited to check out our new “Stopover Ponds/Wetland” brochure. It lists features needed in stopover ponds, and provides diagrams to assist you with planning.
