Nonforested area 



A naturally occurring area where trees do not 

 establish over the long term, such as a bog or 

 avalanche chute. 



Old growth 



Old growth is defined by DNRC as stands that 

 are 150 years and older (140 for lodgepole 

 pine) and that exhibit a range of structviral 

 attributes associated with old age. b«i&! 



»i 



The term old growth is sometimes used to 

 describe the later, or older, stages of natural 

 development of forest stands. Characteristics 

 associated with old-growth generally include 

 relatively large old trees, containing a wide 

 variation in tree sizes, exhibiting some degree 

 of a multi-storied structure, having signs of 

 decadence, such as rot and spike-topped 

 structure, and containing standing large snags 

 and large down logs. 



Overstory 



The level of the forest canopy including the 

 crowns of dominant, codominant and interme- 

 diate trees. 



Patch ^wr^ilf 



A discrete area of forest connected to other 

 discrete forest areas by relatively narrow 

 corridors; an ecosystem element (such as i 

 vegetation) that is relatively homogeneous 

 internally, but differs from what surrounds it. 



Patch shape index ';-: 



A system for assessing patch shape, or a 

 number indicating this shape. The system 

 used in this EIS was developed by McGarigal 

 and Marks (1994). Under this system, a per- 

 fectly square patch is represented by the 

 number 1. Circular patches are indicated with 

 numbers less than one. The higher the number, 

 the more complex the shape. 



j 

 Potential nesting habitat (bald eagle) i 

 Somehmes referred to as 'suitable nesting / 

 habitat', areas that have no history of occu- 

 pancy by breeding bald eagles, but contain 

 potential to do so. 



Project file 



A public record of the analysis process, includ- 

 ing all documents that form the basis for the 

 project analysis. The project file for the Beaver 

 Lake Timber Sale Project EIS is located at the 

 Stillwater State Forest office near Olney, 

 Montana. 



Redds 



The spawning ground or nest of various fish. 



Regeneration 



The replacement of one forest stand by an- 

 other as a result of natural seeding, sprouting, 

 planting, or other methods. 



Residual stand irjiiihnm i^^inf le.'ntni^' 

 Trees that remain standing following any 

 cutting operation. 



Road construction activities 



In general, "road construction activities" refers 

 to all the activities conducted while building 

 new roads, reconstructing existing roads, and 

 obliterating roads. These acHvities may 

 include any or all of the following: 



road construction 



right-of-way clearing 



excavation of cut/ fill material 



installation of road surface and ditch 



drainage features 



installation of culverts at stream crossings 



burning right-of-way slash 



hauling and installation of borrow material 



blading and shaping road surfaces 



Road Improvements -n' 



Construction projects on an existing road to 

 improve ease of travel, safety, drainage, and 

 water quality. 



Saplings 



Trees 1.0 inches to 4.0 inches in diameter at 

 breast height. 



Sawtimber trees 



Trees with a minimum dbh of 9 inches. 



Scarification 



The mechanized gouging and ripping of 

 surface vegetation and litter to expose mineral
