Scoping 



The process of determining the extent of the 

 environmental assessment task. Scoping 

 includes public involvement to learn which 

 issues and concerns should be addressed, and 

 the depth of assessment that will be required. 

 It also includes a review of other factors such 

 as laws, policies, actions by other landowners, 

 and jurisdictions of other agencies that may 

 affect the extent of assessment needed. 



Security 



For wild animals, the freedom from the likeli- 

 hood of displacement or mortality due to 

 human disturbance or confrontation. 



Security habitat (grizzly bears) 



An area of a minimum of 2,500 acres that is at 

 least 0.3 miles from trails or roads with motor- 

 ized travel and high-intensity, nonmotorized 

 use during the nondenning period. 



Seedlings 



Live trees less than 1.0 inch dbh. 



Sediment 



In bodies of water, solid material, mineral or

Shade intolerant 



Describes tree species that generally can only 

 reproduce and grow in the open or where the 

 overstory is broken and allows sufficient 

 sunlight to penetrate. Often these are serai 

 species that get replaced by more shade- 

 tolerant species during succession. In 

 Stillwater State State Forest, shade-intolerant 

 species generally include ponderosa pine, 

 western larch, Douglas-fir, western white pine. 



and lodgepole pine. 



Shade tolerant 



Describes tree species that can reproduce and 

 grow under the canopy in poor sunlight 

 conditions. These species replace less shade- 

 tolerant species during succession. In ■'^■■ 

 Stillwater State Forest, shade-tolerant species 

 generally include subalpine fir, grand fir, 

 Douglas-fir, Engelmann spruce, and western 

 red cedar. 



Sight distance '^^^ 



In the case of grizzly bears, sight distance ''■'-'■ *''^''

Silviculture ri\(^i v,n<Yyih h,

 ment, composition, and growth of forests to

Site Preparation 



A hand or mechanized manipulation of a 

 harvested site to enhance the success of regen- 

 eration. Treatments are intended to modify 

 the soil, litter, and vegetation to create micro- 

 climate conditions conducive to the establish- 

 ment and growth of desired species.
