CONSERVATION SUCCESS
FIGURE 3.26 Species listed for protection under the Endangered Species Act of 1973 (ESA) include the Yellowstone population of grizzly bears, the bald eagle in the lower 48 states, and the whooping crane. Marking the success of the recovery programs supported by the ESA, the Yellowstone grizzly bear and bald eagle populations have recovered sufficiently to be delisted. Meanwhile, the whooping crane population is growing exponentially.
