Noxious Weed: Plants that conflict with, interfere with,or otherwise restrict land management 

 are commonly referred to as weeds. A plant that has been clssified as a weed attains "noxious" 

 status by an act of State legislation. 



Open road: A road that is open year-round with no restrictions. 



Riparian area: Green zones associated with lakes, reservoirs, estuaries, potholes, springs, bogs, 

 fens, wet meadows, and ephemeral, intermittent, or perennial streams. The riparian/wetland 

 zone occurs between the upland or terrestrial zone and the aquatic or deep water zone. 



Salvage Cutting: The removal of dead trees or trees being damaged or killed by injurious agents 

 other than competition, to recover value that would otherwise be lost. (Silviculture Working 

 Group 1993) 



Scarification: A deliberate, moderate disturbance of soil to remove or mix surface duff with 

 less than 1" of surface mineral soil. Scarification provides bare mineral soils for trees that need 

 it to regenerate. It also promotes oxidation of organic matter and speeds its breakdown into 

 nutrients to enrich soil. 



Sensitive species: A U.S. Forest Service designation for plant or animal species that are 

 vulnerable to declines in population or habitat capability which could be accelerated by land 

 management activities. 



Shelterwood: A method of regenerating an even-aged stand in which a new age class develops 

 beneath the partially-shaded environment provided by the residual trees. 



Silviculture: The art and science of controlling the establishment, growth, composition, health, 

 and quality of forests and woodlands. Silviculture entails the manipulation of forest and 

 woodland vegetation in stands and on landscapes to meet the diverse needs and values of 

 landowners and society on a sustainable basis. (Silviculture Working Group 1993) 



Site preparation: A hand or mechanized manipulation of a site designed to enhance the success 

 of regeneration. Treatments may include chopping, discing, bedding, raking, burning, and 

 scarifying. All treatments are designed to modify the soil, litter, and vegetation, and to create 

 microclimate conditions conducive to the establishment and growth of desired species. 

 (Silviculture Working Group 1993) 



Skidding: A loosely-used term for the transportation of logs from stumps to a collecting point 

 by sliding or dragging along the ground— as opposed to the use of wheels, helicopters, balloons, 

 cables, etc., to keep them totally off the ground (After Ford-Robertson 1971 In: Schwarz et al. 

 1976) 



Slash: Branches, tops, and other debris from the cutting of trees. 



Snag: A standing dead tree.
