, Wildlife is an important aspect of forest management because many animals use them for
food, shelter and breeding grounds.
Conservation of Forests... Is not the primary use for forests but is an important use
Recuperation of Forests Avoiding soil erosion and letting forests recover after harvest are key to having a
healthy forest
Forest lands in the US · Total forest land is 737 million acres
· Commercial land (crops and timber) 483 million acres
· Noncommercial (low productivity of timber) 254 million acres
Statistical description of commercial forestland inventories · Timber volume measurement - timber that is (growing stock) that has a DBH of 5
in or more
· Not considered good business to use trees that are less that are 5 in in diameter
even thought they can be used for pup, fuel, and other timber material
· 2/3 of growing stock is softwood and 1/3 is hardwood
· 70% of the 710 cubic feet of growing stock is saw timber size trees which means
that they have A at least one log which is suitable to make lumber
Growth/Harvest ratio` measurement of timber growth as related to harvest
· Most of the growth is on private lands
· Shows that there is no crisis from the loss of timber
Site Quality (Productivity) The productive capacity of a site, usually expressed as volume production of a
given species.
Stand density A quantitative, absolute measure of tree occupancy per unit of land area in such
terms as numbers of trees, basal area, or volume.
site index The maximum timber able to be produced by an area in a given time, or, its
productivity
Density Measures · TPA (Trees per acre)-a density measure which can be used when trees are of the
same age and type
· Volume- a percentage of stocking
· Relative density- a combination of basal area and quadratic mean diameter
· Basal area- cross section measurement of square feet per acre
· Stand density index- measurement of density presented as indices and ratios ex
Reineke's index
· Relative stand density- index that includes the volume of tree growth's relationship
to height
· Crown competition factor- measure of density based on the diameter of the area
that is covered by tree crowns in percentage
Vegetation typing a way of estimating the quality of a site by looking at what plants are present
