Mineral elements such as nitrogen, phosphorus or potassium that are naturally present, or added as fertilizer.
A forest stand containing too many trees per acre, and is evident from slow growth rate. Overstocking reduces growth and makes a stand more susceptible to attack by disease and insects.
This occurs when undesirable tree species (hardwood sprouts in a planted pine forest) grow faster than the seedlings of the desired species, thereby blocking the sunlight from reaching the crowns of the target species and reducing growth.
A stream that flows greater than 90 percent of the time, and has a well-defined channel.
Any chemical or mixture of chemicals used to kill pests. A pest may be an insect, plant, or animal.
Presence of substances that impairs or renders harm to life, health and the productivity of the environment, or is offensive to the senses.
Regrowing a forest on a harvested tract of land using artificial (mechanical or hand planting) or natural (seeds or sprouts) regeneration methods.
Riparian Forest Buffers
Riparian forest buffers are a form of agroforestry that involves the natural or re-established streamside forests made up of tree, shrub, and grass plantings. They buffer non-point source pollution typically created by agricultural operations on land adjacent to waterways.

Seed tree method
A silvicultural practice of even-age natural regeneration. Depending on the site conditions, anywhere from 4 to 10 trees per acre are left standing to provide seed and regenerate the harvested tract. Seed trees should have a well developed root system, a stocky tapering bole, wide deep crown, and a relatively large live crown ratio.
A silvicultural practice of uneven-aged forest management whereby individual or small groups of trees are periodically selected and harvested to create openings in the stand. Regeneration is accomplished by natural processes.
A silvicultural practice of uneven-aged forest management, and is similar to the selection method. However, the major difference is under a shelterwood management regime, between 20 and 60 of the best trees are left standing per acre and provide the seed for natural regeneration.

Streamside Management Zone (SMZ)
The area adjacent to a perennial or intermittent stream in which vegetation is maintained or managed to protect water quality. The width of the SMZ depends on the slope of the land.
