Site Class 



A classification of forest land in terms of inherent capacity to grow 

 crops of industrial wood. Site classifications are based upon the mean 

 annual growth of growing stock (not including thinnings) attainable in 

 fully stocked stands at culmination of mean annual growth. Height-age 

 relationships are usually used as indicators of the specified volume-site 

 class. 



Site index class 



A measure of site productivity based upon the height of trees at a given 

 base age. Site index classes are height classes represented by a 

 graphed curve of height over age for each class. 



Site trees 



Trees measured for height and age, used to estimate site index. 



Softwoods 



Coniferous trees, usually evergreen, having needle or scale-like leaves. 



Stand density 



A quantitative measure of a stand in terms of square feet of basal area, 

 number of trees, or volume per acre. It reflects the degree of crowding 

 of stems within the area. 



Stand-size class 



A classification of forest land based on the class of growing stock trees 

 on the area, that is, sawtimber, pole timber, or seedlings and saplings. 

 (Note: Only those trees that contribute to no more than 16 percent of 

 stocking at a plot point, based upon a 10-point location, will be consid- 

 ered in determining stand-size class) . 



State and other public ownership group 



The ownership group that consists of state, county, municipal, and mis- 

 cellaneous federal land. 



State forest 



Lands administered by the Department of State Lands that are managed 

 as a unit. 



State forest land 



State owned land that is principally valuable for forest and watershed 

 cover that is classified as forest and administered by the Department of 

 State Lands. 



State grazing land 



State owned land that is principally valuable for forage production that 

 is classified as grazing and administered by the Department of State 

 Lands. 



Stocking 



Stocking is an effort to express the extent to which growing space is ef- 

 fectively utilized by present or potential growing-stock trees or commer- 

 cial species. "Percent of stocking" is synonymous with "percentage of 

 growing space occupied" and means the ratio of actual stocking to full
