The U.S. Fish and Wildlife Service has a long tradition of scientific excellence and always uses the best-available science to inform its work to conserve fish, wildlife, plants, and their habitat for the benefit of the American public.
Created in 1903 by President Theodore Roosevelt, today's National Wildlife Refuge System protects habitats and wildlife across the country, from the Alaskan tundra to subtropical wetlands. Managed by the U.S. Fish and Wildlife Service, the Refuge System's 560-plus refuges cover more than 150 million acres and protect nearly 1,400 species of birds, mammals, reptiles, amphibians, and fish.
While national wildlife refuges were created to protect wildlife, they are for people too. Refuges are ideal places for people of all ages to explore and connect with the natural world. We invite you to learn more about and visit the national wildlife refuges and wetland management districts in Colorado, Kansas, Montana, Nebraska, North Dakota, South Dakota, Utah, and Wyoming.
The Mountain-Prairie Region's Office of Ecological Services (ES) works to restore and protect healthy populations of fish, wildlife, and plants and the environments upon which they depend. Using the best available science, ES personnel work with Federal, State, Tribal, local, and non-profit stakeholders, as well as private land owners, to avoid, minimize, and mitigate threats to our Nation's natural resources.
Providing leadership in the conservation of migratory bird habitat through partnerships, grants, and outreach for present and future generations. The Migratory Bird Program is responsible for maintaining healthy migratory bird populations for the benefit of the American people.
The U.S. Fish & Wildlife Service Fish and Aquatic Conservation Program in the Mountain-Prairie Region helps conserve, protect, and enhance aquatic resources and provides economically valuable recreational fishing to anglers across the country. The program comprises 12 National Fish Hatcheries.
Law enforcement is essential to virtually every aspect of wildlife conservation. The Office of Law Enforcement contributes to Service efforts to manage ecosystems, save endangered species, conserve migratory birds, preserve wildlife habitat, restore fisheries, combat invasive species, and promote international wildlife conservation.
External Affairs staff in the Mountain-Prairie Region of the U.S. Fish and Wildlife Service provides support to the regional office and field stations to communicate and faciliate information about the Service's programs to the public, media, Congress, Tribes, partners, and other stakeholders in the 8-state region.

Salt Creek tiger beetle (Cicindela nevadica lincolniana)
Species Description: The Salt Creek tiger beetle (Cicindela nevadica lincolniana) is an active, ground-dwelling, predatory insect that captures smaller or similar sized arthropods in a ‘‘tiger-like’’ manner by grasping prey with its mandibles (mouthparts). The Salt Creek tiger beetle is metallic brown to dark olive green above with a metallic dark green underside. This insect measures about 0.5 inch in total length. It is distinguished from other tiger beetles by its distinctive form and the color pattern on its dorsal and ventral surfaces.
Salt Creek tiger beetle larvae live in permanent burrows in the ground and are voracious predators, fastening themselves by means of abdominal hooks near the tops of their burrows and rapidly extending from them to seize passing invertebrate prey. The adult Salt Creek tiger beetle has a two year life cycle and spends 11 months of the year underground, surfacing for only about six weeks, from around mid June through July. Adults are found in the moist, muddy areas within just a few yards of wetland and stream edges. They have adapted to brief periods of high water inundation and highly saline conditions.
Location: The Salt Creek tiger beetle is confined to eastern Nebraska saline wetlands and associated streams and tributaries of Salt Creek in the northern third of Lancaster County. The insect is believed to have disappeared from the southern margin of Saunders Counties. It is found along mud banks of streams and seeps, and in association with saline wetlands and exposed mud flats of saline wetlands.
On July 15, 2015, the Service announced the availability of a draft revised recovery plan for the Salt Creek tiger beetle. The Service solicits review and comments from the public on the draft revised plan through September 14, 2015.
Actions: On May 5, 2014, the Service announced a final revision of critical habitat for the rare Salt Creek tiger beetle, which was listed as endangered in 2005 under the Endangered Species Act. While only a few hundred beetles remain in three small populations in Nebraska on less than 35 acres, this revision will guide conservation efforts for the species, and includes critical habitat on 1,110 acres of saline wetlands.
On March 12, 2014, the Service announced the availability of a Draft Economic Analysis and Draft Environmental Assessment for the proposed redesignation of critical habitat for the endangered Salt Creek tiger beetle. The Service will open a 15-day public comment period until March 28, 2014, to allow the public to review these draft documents and the June 4, 2013 proposed critical habitat rule.
As of June 3, 2013, we are seeking public input on a proposed revision of critical habitat for the rare Salt Creek tiger beetle. While only a few hundred beetles remain in three small populations in Nebraska on less than 35 acres, this revision will guide conservation efforts for the species, which includes proposed critical habitat for 1,110 acres of saline wetlands. This designation of 1,110 acres is smaller than the previous designation, but contains sufficient suitable habitat to support recovery of the species, and includes two additional stream corridors that were not previously included which could support Salt Creek tiger beetle populations in the future. The goal of this designation is to support at least 6 populations of Salt Creek tiger in the future. The Service has opened a 60-day comment period to allow the public and stakeholders an opportunity to comment on this proposal through August 5, 2013.
On June 20, 2011, we initiated 5-year status reviews under the Endangered Species Act of 1973, as amended (Act), of 2 animal and 10 plant species. We are requesting any information that has become available since our original listing of each of these species. Based on review results, we will determine whether we should change the listing status of any of these species.
The U.S. Fish and Wildlife Service has designated approximately 1,933 acres of land in Lancaster and Saunders Counties, Nebraska, as critical habitat for the endangered Salt Creek tiger beetle.
The four areas designated as critical habitat are: (1) Upper Little Salt Creek North in Lancaster County, (2) Little Salt Creek – Arbor Lake in Lancaster County, (3) Little Salt Creek – Roper in Lancaster County, and (4) Rock Creek – Jack Sinn Wildlife Management Area in Lancaster and Saunders Counties. Saline wetland and stream complexes found along Little Salt Creek and Rock Creek comprise the critical habitat designation.
Critical habitat is a term defined in the Endangered Species Act. It identifies geographic areas containing features essential for the conservation of a threatened or endangered species and may require special management considerations or protection.
On February 20, 2009, we completed a recovery outline for the Salt Creek tiger beetle. This document provides a basic background about the Salt Creek tiger beetle and a preliminary course of actions to achieve recovery of the insect. It serves to guide recovery efforts, consultation, land use planning, and permitting activities until a comprehensive recovery plan for the Salt Creek tiger beetle is finalized and approved. We hope to complete a comprehensive recovery plan for the Salt Creek tiger beetle in 2010.
On October 6, 2005, the Service listed the Salt Creek tiger beetle as endangered under the U.S. Endangered Species Act. This species is endemic to the saline wetlands of eastern Nebraska and associated streams in the northern third of Lancaster County and southern margin of Saunders County. Only three small populations of this subspecies remain, and the known adult population size in 2005 was only 153 individuals. This final action extends Federal protection and recovery provisions of the Act to the Salt Creek tiger beetle.
The Service’s proposal states that surveys from 1991 to 2004 show declines in population size and distribution. The surveys indicate that the number of remaining Salt Creek tiger beetle populations has fallen by half – from six to three populations – since 1991. The 2004 surveys revealed that the Salt Creek tiger beetle numbers fewer than 600 individuals.
