Wildlife

Wildlife

Wild life refers to all living things (except people) that are undomesticated including animals, fish, birds, insects and other animals.

Glossary of wildlife

• abiotic nonliving; a physical feature of the environment such as climate, temperature, geology, soils.

• avullium an unconsolidated accumulation of stream-deposited sediments, often including sands, silts, clays, or gravels.

• alternative a set of objectives and strategies needed to achieve refuge goals and the desired future condition.

• ambient of the surrounding area or outside environment.

• anadromous fish fish that spend a large portion of their life cycle in the ocean and return to freshwater to breed.

• appropriate use a proposed or existing use on a refuge that meets at least one of the following three conditions: 1. the use is a wildlife-dependent one; 2. the use contributes to fulfilling the refuge purpose(s), the System mission, or goals or objectives described in a refuge management plan approved after October 9, 1997, the date the National Wildlife Refuge System Improvement Act was signed into law; or 3. the use has been determined appropriate as specified in section 1.11 of that act.

• approved acquisition boundary a project boundary that the Director of the U.S. Fish and Wildlife Service approves upon completion of the planning and environmental compliance process. An approved acquisition boundary only designates those lands that the Service has authority to acquire or manage through various agreements. The approval of an acquisition boundary does not grant the Service jurisdiction or control over lands within the boundary, and it does not make lands within the refuge boundary part of the National Wildlife Refuge System. Lands do not become part of the System until the Service buys them or they are placed under an agreement that provides for their management as part of the System.

• avian of or having to do with birds.

• basin the surrounding land that drains into a water body.

• best management practice land management practices that produce desired results (usually describing forestry or agricultural practices effective in reducing non-point source pollution.

• biological diversity the variety of life forms and its processes, including the variety of living organisms, the genetic differences among them, and the communities and ecosystems in which they occur.

• biological integrity biotic composition, structure, and functioning at genetic, organism, and community levels comparable with historic conditions, including natural biological processes that shape genomes, organisms, and communities.

• bird conservation region ecologically distinct regions in North America with similar bird communities, habitats, and resource management issues.

• brackish brackish water is water that is more salty than freshwater, but less salty that seawater. It is generally defined as water with a salinity of 0.5 to 30 dissolved salts parts per thousand.

• buffer lands bordering water bodies that reduce runoff and nonpoint source pollution.

• canopy the layer of foliage formed by the crowns of trees in a stand. For stands with trees of different heights, foresters often distinguish among the upper, middle and lower canopy layers. These represent foliage on tall, medium, and short trees. The uppermost layers are called the overstory.

• categorical exclusion a category of Federal agency actions that do not individually or cumulatively have a significant effect on the human environment.

• compatible use a wildlife-dependent recreational use, or any other use on a refuge that will not materially interfere with or detract from the fulfillment of the mission of the Service or the purposes of the refuge.

• compatibility determinations a required determination for wildlife-dependent recreational uses or any public uses of a refuge.

• Comprehensive Conservation Plan a document that describes the desired future conditions of the refuge, and specifies management direction to achieve refuge goals and the mission of the National Wildlife Refuge System.

• community a distinct assemblage of plants that develops on sites characterized by particular climates and soils, and the species and populations of wild animals that depend on the plants for food, cover and/or nesting.

• cover type the current vegetation of an area.

• cultural resource those parts of the physical environment – natural and built – that have cultural values to some sociocultural group or institution.

• Cultural resources include historic sites, archaeological sites and associated artifacts, sacred sites, buildings, and structures.

• diameter at breast height (dbh) – the diameter of the stem of tree measure at breast height (usually 4.5 feet above the ground). The term is commonly used by foresters to describe tree size.

• disturbance a disruption in the natural plant succession of a community or ecosystem resulting in a new community.

• early successional habitat Succession is the gradual replacement of one plant community by another. In a forested ecosystem, tree cover can be temporarily displaced by natural or human disturbance (e.g., flooding by beaver, or logging). The open environments created by removal of tree cover are referred to as ‘early-successional’ habitats because as time passes, trees will return. The open conditions occur ‘early’ in the sequence of plant communities that follow disturbance. We define early successional forest in this CCP as: the shrub-sapling stage; 0-20 years old.

• ecological integrity native species populations in their historic variety and numbers naturally interacting in naturally structured biotic communities. For communities, integrity is governed by demographics of component species, intactness of landscape-level ecological processes (e.g., natural fire regime), and intactness of internal community processes (e.g., pollination).

• ecological succession the orderly progression of an area through time in the absence of disturbance from one vegetative community to another.

• ecoregion a territory defined by a combination of biological, social, and geographic criteria, rather than geopolitical considerations; generally, a system of related, interconnected ecosystems.

• ecosystem a dynamic and interrelated complex of plant and animal communities and their associated non-living environment.

• emergent marsh wetlands dominated by erect, rooted, herbaceous plants.

• endangered species any species of plant or animal defined through the Endangered Species Act as being in danger of extinction throughout all or a significant portion of its range, and published in the Federal Register.
• Environmental Assessment a systematic analysis to determine if proposed actions would result in a significant effect on the quality of the environment.

• environmental health the composition, structure, and functioning of soil, water, air, and other abiotic features comparable with historic conditions, including the natural abiotic processes that shape the environment.

• exotic species a species that is not native to an area and has been introduced intentionally or unintentionally by humans.

• extinction the termination of existence of a lineage of organisms (e.g., a subspecies or species.

• federally listed species a species listed either as endangered, threatened, or species at risk (formerly a “candidate” species) under the Endangered Species Act of 1973, as amended.

• fragmentation the process of reducing the size and connectivity of habitat patches; the disruption of extensive habitats into isolated and small patches.

• geographic information system a computer system capable of storing and manipulating spatial mapping data; more commonly referred to by the acronym GIS goals descriptive statements of desired future conditions.

• habitat the sum of environmental factors – food, water, cover, and space – that each species needs to survive and reproduce in an area.

• hectare equal to 2.47 acres.

• historic conditions the composition, structure, and functioning of ecosystems resulting from natural processes that we believe, based on sound professional judgment, were present prior to substantial human- related changes to the landscape.

• impoundment a body of water, such as a pond, confined by a dam, dike, floodgate, or other barrier, that is used to collect and hold water.

• interjurisdictional fish populations of fish that are managed by two or more State or national or tribal governments because of the scope of their geographic distributions or migrations.

• invasive species a non-native species whose introduction causes or is likely to cause economic or environmental harm or harm to human health.

• marl An unconsolidated sedimentary rock or soil consisting of clay and lime.

• migratory bird a bird species that migrates between wintering and breeding grounds.

• National Wildlife Refuge System all lands, waters, and interests therein administered by the U.S. Fish and Wildlife Service as wildlife refuges, wildlife ranges, wildlife management areas, waterfowl production areas, and other areas for the protection and conservation of fish, wildlife and plant resources.

• nonpoint source pollution a diffuse form of water quality degradation in which wastes are not released at one specific, identifiable point but from a number of points that are spread out and difficult to identify and control.

• objectives actions to be accomplished to achieve a desired outcome or goal. Objectives are more specific, and generally more measurable, than goals.

• physiographic area a bird conservation planning unit with relatively uniform vegetative communities, bird populations, and species assemblages, as well as land use and conservation issues, developed by Partners in Flight.

• point source pollution a source of pollution that involves discharge of waste from an identifiable point, such as a smokestack or sewage-treatment plant.

• priority public use a compatible wildlife-dependent recreational use of a refuge involving hunting, fishing, wildlife observation and photography, or environmental education and interpretation.

• range the geographic area within which a particular species is found.

• restoration management of a disturbed or degraded habitat that results in the recovery of its original state (e.g., restoration may involve planting native species, removing invasive shrubs, prescribed burning).

• riparian relating the floodplains, banks, and terraces that line rivers.

• riparian area habitat along the banks of a stream, river, or wetland.

• scoping a process for determining the scope of issues to be addressed by a comprehensive conservation plan and for identifying the significant issues. Involved in the scoping process are federal, state and local agencies; private organizations; and individuals.
