Adequately stocked: means a total stand density of commercially valuable species of not less than 800 trees/ha on the coast and 1000 trees/ha in the interior that are at least 1.3 metres in height.
Adjacent: means an area contiguous to, or in close proximity to,
a. a road or proposed road
b. a cutblock
c. an area under a stand management prescription
that, due to its location, could directly impact on, or be impacted by a forest practice carried out within the area of the road, cutblock or prescription.
Biological diversity: the diversity of plants, animals and other living organisms in all their forms and levels of organization and includes the diversity of genes, species, ecosystems and the evolutionary and functional processes that link them.
Clearcut: a silvicultural system that
Clearcut with reserves: a variation of clearcutting in which trees are retained, either uniformly or in small groups, for purposes other than regeneration.
Community watershed: a community watershed as defined in section 41 (8) of the Act.
Cutblock: a cutblock as defined in the Act, except that for the purposes of green-up, the forest development plan or permit referred to in that definition means the most recently approved plan, licence or permit for the area, whether or not it has expired.
Even-aged stand: a stand of trees consisting of one or two age classes.
Free growing stand: a stand of healthy trees of a commercially valuable species, the growth of which is not impeded by competition from plants, shrubs or other trees.
Green-up height: a height of three or 3.5 metres or as varied by the district manager and is based on the average height of the tallest tree (of a commercially valuable species or other species acceptable to the district manager) in each of a representative sample of 0.01 (1/100th) hectare plots.
Green-up survey: a survey used to determine if the species, stocking, height, and block coverage requirements for green-up as set out in OPR have been met in a previously harvested cutblock.
Group selection: a silvicultural system that
Higher level plan: means an objective for a
Hydrologic green-up: the height and crown closure at which a second growth stand will hydrologically resemble old growth in terms of timing and quantity of water yield.
Net area: the net area to be reforested as identified in the most recent silviculture prescription for the cutblock, whether or not the silviculture prescription has expired or, if no silviculture prescription identifies a net area to be reforested, it is the area of the cutblock excluding all of the following: any area occupied by permanent access structures; any area of rock, wetland or other area that in its natural state is incapable of growing commercially valuable trees; any contiguous area within the cutblock of more than four hectares that is composed of non-commercial forest cover; or any area reserved from harvesting because of wildlife trees or riparian reserve zones.
Partial cutting: a silvicultural system in which only selected trees are harvested and includes seed tree, shelterwood, single-tree and group selection, and clearcutting with reserves.
Patch cutting: a silvicultural system that creates openings of less than one hectare and is designed to manage each opening as a distinct even-aged opening.
Private tenure: a timber licence, old temporary tenure, or private land in a tree farm licence area.
Sanitation treatment: tree removal or modification operations designed to reduce damage caused by forest pests and to prevent their spread.
Scenic area: any visually sensitive area or scenic landscape identified through a visual landscape inventory or planning process carried out or approved by the district manager.
Seed tree: a silvicultural system in which selected trees are left standing after the initial harvest to provide a seed source for natural regeneration.
Shelterwood: a silvicultural system in which trees are removed in a series of cuts designed to achieve a new even-aged stand under the shelter of remaining trees.
Single tree selection: a silvicultural system in which age classes are created or maintained by the removal, uniformly throughout the stand, of individual trees of all size classes.
Uneven-aged stand: a stand of trees consisting of three or more age classes.
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.
Visual quality objective: a resource objective established by the district manager or contained in a higher level plan that reflects the desired level of visual quality based on the physical characteristics and social concern for the area.
Watershed assessment: an assessment of the cumulative impact that proposed activities and developments would have on stream flows, suspended sediment, landslide and stream channel stability within the watershed.
