Items starting with C

Conservation Agreement

A formal signed agreement between the U.S. Fish and Wildlife Service or National Marine Fisheries Service and other parties that implements specific actions, activities, or programs designed to eliminate or reduce threats or otherwise improve the status of a species. CA's can be developed at a State, regional, or national level and generally includes multiple agencies at the State and Federal level, as well as tribes. Depending on the types of commitments the BLM makes in a CA and the level of signatory authority, plan revisions or amendments may be required prior to signing the CA, or subsequently in order to implement the CA.

Conservation Strategy

A strategy outlining current activities or threats that are contributing to the decline of a species, along with the actions or strategies needed to reverse or eliminate such a decline or threats. Conservation strategies are generally developed for species of plants and animals that are designated as BLM Sensitive species or that have been determined by the Fish and Wildlife Service or National Marine Fisheries Service to be Federal candidates under the Endangered Species Act.

Consistency

means that the proposed land use plan does not conflict with officially approved plans, programs, and policies of tribes, other Federal agencies, and State and local governments to the extent practical within Federal law, regulation, and policy.

Consumptive Use

Use of resources that reduces the supply, such as logging and mining.

Contiguous

Used in a geographic sense, the term applies to situations where areas of land physically touch and share substantial common boundaries or have a common border of considerable length. The term is not intended to include 'point-to-point' touching or 'cornering', or instances where only small portions of land areas touch. It is not intended to encompass or encourage creative mapping exercises that result in irregular shapes, such as narrow corridors and 'gerrymandered' roadless areas.

Contour

A line drawn on a map connecting points of the same elevation.

Cooperating Agency

Assists the lead Federal agency in developing an EA or EIS. The Council on Environmental Quality regulations implementing NEPA defines a cooperating agency as any agency that has jurisdiction by law or special expertise for proposals covered by NEPA (40 CFR 1501.6). Any tribe or Federal, State, or local government jurisdiction with such qualifications may become a cooperating agency by agreement with the lead agency.

Coppice method

Regeneration method in which all trees in the previous stand are cut, and the majority of regeneration is from sprouts and root suckers.

Corridor

Elements of the landscape that connect similar areas. Streamside vegetation may create a corridor of willows and hardwoods between meadows where wildlife feed.

Cover

Any feature that conceals wildlife or fish. Cover may be dead or live vegetation, boulders, or undercut streambanks. Animals use cover to escape from predators, rest, or feed.

Cover Forage Ratio

The ratio of hiding cover to foraging areas for wildlife species.

Cover Type (forest cover type)

Stands of a particular vegetation type that are composed of similar species. The aspen cover type contains plants distinct from the pinyon-juniper cover type.

Created Opening

An opening in the forest cover created by the application of even-aged silvicultural practices.

Criteria air pollutants

A group of common air pollutants (such as carbon monoxide, particulate matter, or ozone) regulated by the Environmental Protection Agency (EPA) on the basis of criteria (information on health and/or environmental effects of pollution). Criteria air pollutants are widely distributed across the country.

Critical Habitat

Areas designated for the survival and recovery of federally listed threatened or endangered species.
