Final
Sandhill Crane Draft
Sandhill Crane
In 1990, the Washington Wildlife Commission adopted procedures for listing and de-listing species as endangered, threatened, or sensitive and for writing recovery and management plans for listed species (WAC 232-12-297, Appendix A). The procedures, developed by a group of citizens, interest groups, and state and federal agencies, require preparation of recovery plans for species listed as threatened or endangered. Recovery, as defined by the U.S. Fish and Wildlife Service, is “the process by which the decline of an endangered or threatened species is arrested or reversed, and threats to its survival are neutralized, so that its long-term survival in nature can be ensured.” This document summarizes the historic and current distribution and abundance of sandhill cranes in Washington and describes factors affecting the population and its habitat. It prescribes strategies to recover the species, such as protecting the population, evaluating and managing habitat, and initiating research and education programs. Target population objectives and other criteria for reclassification are identified and an implementation schedule is presented. The draft state recovery
plan for the sandhill crane was reviewed by researchers and state and
federal agencies. This review was followed by a 90-day public comment
period. All comments received were considered in preparation of this the
final recovery plan. For additional information about sandhill cranes

FINAL Executive Summary The historical distribution of breeding cranes in Washington was poorly documented, but the few historical accounts mention breeding in south-central, northeastern and southeastern regions, and the southern Puget Sound Basin. Crane numbers had been severely reduced due to widespread habitat destruction concurrent with human settlement, and perhaps more importantly, unregulated hunting which continued until passage of the federal Migratory Bird Treaty Act in 1916. The species was extirpated as a breeder from the state after 1941 when the last nest was documented at Signal Peak, Yakima County, in south-central Washington. Some 31 years later, they were again found summering in the Glenwood Valley on Conboy Lake National Wildlife Refuge, Klickitat County in 1972, but it was not until 1979 that nesting was confirmed. A total of 19 territorial pairs was documented in 2000: 16 at Conboy Lake National Wildlife Refuge; and 1 each on Yakama Indian Nation lands, Yakima County; Panakanic Valley, Klickitat County; and on Washington Department of Natural Resource (WDNR) lands along Deer Creek, Yakima County. The total summer population in Washington in 2000 was 53 birds. No nests produced chicks to fledging age in 2001, probably due to factors relating to drought conditions; the total summer population was 50. Factors affecting Washington’s breeding greater sandhills include predation, incompatible grazing and haying practices, water availability and management, and habitat loss. Crane habitat on the lower Columbia bottomlands between Vancouver and Woodland is threatened with industrial development, conversion of agricultural lands to cottonwood plantations, tree nurseries, or other incompatible uses and crane use is affected by disturbance by hunters and other recreationists. The goal of the recovery plan is to restore a healthy breeding population of cranes and to maintain the flocks that winter or stop in Washington. To reach this goal, this plan calls for expansion of the breeding range of greaters into former breeding areas in eastern Washington and protection of habitat for crane wintering and staging during migration. The Plan identifies recovery objectives that must be reached, and outlines strategies to use in meeting them before down-listing of the species to threatened or sensitive can occur. The sandhill crane will be considered for down-listing from State Endangered to State Threatened status when the state’s overall breeding population reaches at least 65 territorial pairs with an average annual recruitment rate of >8%, and effective water management control is established at Conboy Lake National Wildlife Refuge. The sandhill crane will be considered for down-listing to State Sensitive when the state’s breeding population reaches at least 130 territorial pairs with an average annual recruitment rate of >8%, and habitat used by cranes at the major staging sites in eastern Washington is protected through management agreements or easements. Also, for down-listing to sensitive, habitat needed to maintain 2,000 migrant and 500 wintering cranes should be secured and managed for cranes on the lower Columbia River bottomlands in Washington. Recovery objectives may need to be updated as better information is available about habitat needs.
