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.
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.
