is no riparian reserve zone, that is located adjacent to the lake. |
|

the process by which decisions are made on future
land uses over extended time periods, that are deemed to best serve the general
welfare. |
|
Landform:
a landscape unit that denotes origin and shape, such as a
floodplain, river terrace, or till plain. |
|
Landing: an area modified by equipment that is designed for
accumulating logs before they are transported. |
|
Landing pile or cull pile:
an area of piled slash, logging residue,
and stumps, created as a result of harvesting operations and the construction of
roads and landings. |
|
Landscape:
the fundamental traits of a specific geographic area,
including its biological composition, physical environment and antHRopogenic or
social patterns. |
|
Landscape ecology:
the study of the distribution patterns of
communities and ecosystems, the ecological processes that affect those patterns
and changes in pattern and process over time. |
|
Landscape inventory:
see Visual landscape
inventory. |
|
Landscape level: a watershed, or series of interacting watersheds or
other natural biophysical (ecological) units, within the larger Land and
Resource Management Planning areas. This term is used for conservation planning
and is not associated with visual landscape management and viewscape management. |
|
Landscape sensitivity:
a component of the landscape inventory that
estimates the sensitivity of the landscape based on: the visual prominence of
importance of features; conditions that affect visual perception; and social
factors that contribute to viewer perceptions. |
|
Landscape unit: For the purpose of the forest practices code,
landscape units are planning areas delineated on the basis of topographic or
geographic features. Typically they cover a watershed or series of watersheds,
and range in size from 5000 to 100 000 ha. |
|
Landscape unit objectives:
objectives established for a landscape unit
to guide forest development and other operational planning. Landscape objectives
are established by the Ministry of Forests' district manager and a designated
B.C. Environment official. |
|
Large Organic Debris (LOD):
entire trees or large pieces of trees that
provide channel stability or create fish habitat diversity in a stream channel. |
|
Large woody debris: a large tree part, conventionally a piece greater
than 10 cm in diameter and 1 m in length. |
|
Leader:
the length of tree stem from the top of the tree down to the
first set of branches, representing one year of growth and reflecting the tree's
vigor and the site's growing potential. |
|
Leave trees:
all trees, regardless of species, age, or size, remaining
on a harvested area as a result of a predetermined silviculture prescription to
address a possible range of silviculture or resource needs. |
|
Licence to cut: an agreement under the
Forest Act
allowing a person who purchases or occupies land, and who does not otherwise
have the right to harvest Crown timber from the land, to cut and/or remove
timber on the land. |
|
Lightning detection system: a network of electronic field sensors
linked to a central computer to detect, triangulate, plot the location of and
record cloud-to-ground lightning flashes in real time over a predetermined area. |
|
Limiting factor: a factor present in an environment in such short
supply that it limits growth or some other life process. |
|
Linear developments: straight line industrial development that is
typical of power lines, highways, gas lines, and seismic activities. |
|
Litter layer: the layer of organic debris, mainly bark, twigs, and
leaves, on the forest floor. |
|
Littoral zone: the shore zone between the high and low water mark. |
|
Local Planning: A term describing a variety of resource planning
initiatives undertaken to develop integrated approaches to resource use and
development. Typically they have been undertaken to resolve potential land-use
conflicts in local areas smaller than LRMPs. |
|
Livestock: as defined in theRange Act and Silviculture Planning
Regulations means animals of the genus Bos, horses, mules, asses, sheep and
goats, but does not include wildlife designated under the Wildlife Act, exotic
game animals, buffalo, swine or poultry but does include llamas. |
|
Local Resource Use Plan (LRUP):
A plan approved by the
district manager for a portion of the provincial forest that provides
area-specific resource management objectives for integrating resource use in the
area. These plans are prepared pursuant to Section 4 (c) of the Ministry of
Forests Act. |
|
Log boom: floating logs tied together in rafts to be towed by boat to
their destination. |
|
Logging:
see Harvesting. |
|
Logging (cutting) plan: a map, along with a written plan, describing
the road building, harvesting, and other related operations that are submitted
for a forest officer's approval to ensure that the applicable standards and
obligations stated in the
Pre-Harvest
Silviculture Prescription and the harvesting agreement are met. |
|
Logging trail: a narrow, temporary path used by harvesting equipment. |
|
Long Run Sustainable Yield (LRSY):
the long run sustainable yield for
any Timber Supply Area (TSA) is equal to the culmination of mean annual
increment weighted by area for all productive and utilizable forest land types
in that TSA including all not satisfactorily restocked, disturbed stocking
doubtful, and potentially usable noncommercial cover. |
|
Lopping: chopping branches, tops and small trees after felling into
lengths such that the resultant slash will lie close to the ground. |
|
Lopping and scattering:
lopping the slash created after felling and
spreading it more or less evenly over the ground without burning. |
|
Loss factors:
reductions made to gross timber volumes to allow for
decay, waste, and breakage. |
|
