General wildlife measure: defined in the Forest Practices Code of British Columbia Act Operational Planning Regulation as a management practice that the Deputy Minister of Environment, Lands and Parks, or a person authorized by that deputy minister, and the chief forester determine is necessary to maintain the habitat of one or more species of identified wildlife.

Geographic information system (GIS): a computerized information system that uses a spatial database to store, retrieve, map and tabulate land and resource data. GIS will provide answers to queries of a geographic nature through a variety of manipulations such as sorting, selection retrieval, calculation, spatial analysis and modeling.

Glaciolacustrine material: soil materials transported by glaciers and deposited by glacial meltwater in glacier lakes.

Green up: the process of re-establishing vegetation following logging to achieve specific management objectives (for example, rate of harvest control, visual cover for wildlife, visual quality, or hydrological recovery). The most common standards are:

green-up: the minimum height and stocking levels which trees (as described in either a silviculture prescription or regional stocking standards) on a cutblock must achieve before an adjacent stand of timber may be harvested.
visually effective green-up: the stage at which regeneration on a cutblock is perceived by the public as being newly established forest. The forest cover on the cutblock must generally be of sufficient height to block stumps, logging debris, and bare ground from view. Once achieved, an adjacent stand of timber is available for harvest.
hydrological green-up: the point at which a second-growth stand of timber will hydrologically resemble old growth in terms of timing and quantity of water yield.

Greened-up: defined in the Forest Practices Code of British Columbia Act Operational Planning Regulation as a cutblock that supports a stand of trees that

a) has attained the green-up height specified in a higher level plan for the area, or

b) in the absence of a higher level plan for the area, has attained a height that is three metres or greater, and

i) if under silviculture prescription, meets the stocking requirements of that prescription, or

ii) if not under a silviculture prescription, meets the stocking specifications for that biogeoclimatic ecosystem classification specified by the regional manager.

Group selection system: a variant of the selection silvicultural system. It is defined as a silvicultural system that removes trees in defined groups to create stand openings with a width less than two times the height of adjacent mature trees, and that manages the area as an uneven-aged stand.

Guidebooks: guidebooks are sets of guidelines and recommendations on how to best achieve the requirements of the Forest Practices Code of British Columbia Act. The guidebooks are not legally enforceable. However, specifications and procedures recommended by the guidebooks may be incorporated into plans, prescriptions and contracts in which case those specifications and procedures may become legally enforceable.
