Abstract

National Wildlife Refuges are established with a range of management purposes as a result of a variety of acquisition authorities including legislative mandate, executive order, and establishing memorandum. The National Wildlife Refuge System Improvement Act of 1997 mandates that each refuge shall be managed to fulfill the System mission and its establishing purposes, as well as to maintain the System's overall biological integrity, diversity, and environmental health. We offer the Sacramento National Wildlife Refuge as a case study demonstrating the challenges a refuge staff faces when implementing management practices that achieve refuge purposes while also maintaining and, where appropriate, restoring biological integrity, diversity, and environmental health as well as complying with a multitude of other legislative mandates and policies.

*PERIODICAL articles, *SNOW goose, *OVERPOPULATION, SACRAMENTO National Wildlife Refuge (Calif.)
Abstract

An article on Saturday about a population explosion among snow geese misidentified a type of bird that snow geese may try to displace when they arrive in the waters of the Sacramento National Wildlife Refuge in the wintertime. It is the white-fronted goose, not the white-footed goose. And the article referred imprecisely to the Tule goose. It is a subspecies of the white-fronted goose, not a separate species.
