Final Environmental Impact Statement

Vestal Final Environmental Impact Statement Chapter 5
Slash
Snag
The residue left on the ground after harvesting, sanitation operations, windstorm,
or fire. It includes such material as unutilized logs, uprooted stumps, broken or
uprooted stems, tops, branches, and leaves.
Standing dead tree or standing portion from which at least the leaves and smaller
branches have fallen; often called a stub if it is less than 20 feet tall.
Soil Productivity
The inherent capacity of a soil to support the growth of specified plants, plant
communities, or a sequence of plant communities. Soil productivity may be
expressed in terms of volume or weight/unit area/year, percent plant cover, or
other measures of biomass accumulation.
Standard
Mandatory courses of action; any deviation from standards requires amendment
of the LRMP.
Stand
A community, particularly of trees, possessing sufficient uniformity as regards to
vegetation type, age class, risk class, vigor, size class, and stocking class that
distinguishes it from adjacent communities and thus forms a management or
silvicultural unity. Within a stand, a dominant or primary species and age class is
identifiable, but there may be inclusions or clusters of different species or ages.
R2 RIS stands are typically greater than 10 acres. IRI stands are typically greater
than 5 acres.
Stand-replacing Fire
A fire that kills all or most living overstory trees in a forest and initiates
secondary succession or regrowth.
State Historic Preservation Officer (SHPO)
A person appointed by a state's governor to administer the State Historic
Preservation Program.
Stream Health
The condition of a stream relative to robust health for that stream type and
landscape, considering indicators such as channel pattern; slope; particle size;
pool frequency and depth; bank vegetation; and woody debris that reflect the
stability and habitat quality of the stream.
Stream Level
A classification of the relative position of streams in a channel network. Firstlevel
streams drain into the ocean. Second-level streams are tributaries to the
first-level streams. For example, the Mississippi is a first-level stream; the
Missouri is a second-level stream.
Structural Stages (Vegetation)
Any of several developmental stages of tree stands described in terms of tree size
and the extent of canopy closure they create. They include:
