A

Access

(verb) To enter an area, by land, water or air.
(noun) Physical entry into an area or a physical feature, such as a road, track, trail, aircraft landing site or boat launch, that makes entry into an area easier.

Access management

Steps taken to make entry into an area either easier or harder, depending on the desired management goal (e.g., enhancing resource development; protecting wildlife). Can be limited to defined areas, certain periods of time, or specific uses. Ways to manage access include public education, signs, regulations, or physical barriers such as gates.

Aggregate

Earth materials used for construction purposes (e.g., sand, gravel, crushed rock).

Agricultural Land Reserve (ALR)

Land dedicated for agricultural use and regulated by the Agricultural Land Commission Act. The reserve covers about 5% of the province and includes most of BC’s highest quality agricultural land. The reserve includes private and public lands, land that is currently being farmed, and land that has agricultural potential. Some non-agricultural uses of the ALR are also allowed, subject to regulations.

Alienation

Allowable annual cut (AAC)

The average volume of wood that may be harvested each year under sustained yield management. It is usually expressed as “cubic metres of wood per year.” The Chief Forester sets the AAC for timber supply areas (Sub Regions) and tree farm licences (TFLs) in accordance with Section 8 of the Forest Act.

Alpine

(geography) Of or relating to mountains.
(biology) Living or growing on mountains above tree line.

Compensate

To offset an error, a defect or an undesired effect; to make up for; to counterbalance; to make payment or reparation for.

Connectivity

A qualitative term describing the degree to which late-successional ecosystems are linked to form an interconnected network. The degree of interconnectedness and the characteristics of the links vary in natural landscapes due to topography and types of natural disturbance. Breaking these links results in fragmentation.

Consider

To give serious thought to; to think carefully about; to take into account. Synonym: ponder, weigh.

Corridor

A band of vegetation, usually older forest, which serves to connect distinct patches on the landscape. By providing connectivity, corridors permit the movement of plant and animal species between what would otherwise be isolated patches.

Critical grizzly bear habitat

Areas that are well suited for food, bedding or denning, especially where these are in short supply. They include avalanche tracks, meadows and wetlands that are rich in herbs, glacier lilies, white bark pine, skunk cabbage and berries. Salmon spawning areas are also important.
