BOARD OF SUPERVISORS
The governing body of the Township of Marshall.

BUILDING PERMIT
An official document or certificate issued by the Building Official which authorizes performance of a specified building activity.
CLEAR-CUTTING

FOREST MANAGEMENT PLAN
A plan establishing best conservation and management practices for a landowner relative to timber resources.
FORESTRY
The management of forests and timberlands when practiced in accordance with accepted silvicultural principles, through developing, cultivating, harvesting, transporting and selling trees for commercial purposes, which does not include any land development [per the current Municipalities Planning Code (MPC)[1]].
GRADING
An excavation, fill, or reshaping of the ground surface involving any combination thereof, including the conditions resulting from any excavation or fill.
INTERMITTENT STREAM
A stream whose water flow normally occurs in the wetter parts of the year (October through April) or following major storm events.
LAND DEVELOPMENT
Those activities as defined in the current Municipalities Planning Code (MPC)[2].
LAND USE CHANGE
Conversion of forest land to uses such as residential, commercial, industrial, etc., where forest management practices relative to timber production and harvesting are no longer practical.
LANDING
A place where logs, pulpwood, or firewood is assembled for transportation to a processing facility.
LANDSLIDE-PRONE AREAS
Any geologic formation that is especially susceptible to landslides due to the presence of one or more conditions such as unstable rock formations, soil types, groundwater seepage or saturated soils, including, without limitation, areas containing soils identified as landslide-prone in the Soil Survey of Allegheny County or other applicable maps or surveys.
LITTER
Discarded items not naturally occurring on the site (i.e., tires, oil cans, etc.).
MAJOR TIMBER HARVESTING OPERATION
A timber harvesting operation that encompasses a land area in excess of two acres, takes place on any land exceeding a 4H:1V, or involves the clear-cutting or seed-tree-cutting methods or any other method deemed by the Township to be similarly intensive.
MINOR TIMBER HARVESTING OPERATION
A timber harvesting operation that does not classify as a major timber harvesting operation.
NONCOMMERCIAL TIMBER STAND IMPROVEMENT
A practice in which the quality of the residual forest stand is improved by removing the less desirable trees, vines, and occasionally large shrubs to obtain the preferred stocking of the best quality trees. It can also include such practices as tree pruning. A noncommercial timber stand improvement is involved with the removal of the above-mentioned trees, etc., but does not yield a net income, usually because the trees cut are too small, poor quality, or are not marketable.
OPERATIONS

SELECTIVE-CUTTING-METHOD
A method of selectively removing trees from a wooded area either singly or in small groups according to age and size with provisions being made for natural or artificial vegetation. This method is used for regenerating trees that grow well in shade such as beech, maple, and hemlock.
SHELTERWOOD-CUTTING METHOD
A timber harvesting method in which trees are harvested in a series of cuts designed to achieve a new even-aged stand under the shelter of remaining trees. This method is used for regenerating intermediate shade-tolerant trees such as white pine and northern red oak.
SITE
A lot, tract, parcel of land, or a series of lots. Tracts or parcels of land which are adjoining where a timber harvesting operation is continuous and performed at the same time.
SKIDDING
The act of dragging trees on the ground, by any means, from the stump to the landing.
SLASH

VERNAL POOL
An isolated, contained basin depression that holds water for at least two months in the spring and summer, critical to several amphibian, reptile, and invertebrate species. It also provides important storage for stormwater runoff and spring snowmelt that would otherwise contribute to downstream flooding.
