Silvicultural Prescription

OBJECTIVE: Precommercial thin the stand to a stocking level and spatial arrangement to achieve maximum site growth potential. Leave a mixed species stand of healthy conifers. Reduce competition on selected crop trees allowing them to be free to grow and improve vigor. Improve the overall health of the stand by eliminating diseased or damaged trees.

Other instructions:

Select the best available tree within a decision area. Crop trees should exhibit the best growth for the past three years, have good form and color, be relatively free of insects, disease or mechanical damage. Refer to Desirable leave tree characteristics C.2. Note strong preference to smaller ES over LP with stem disease. Fall trees away from the private property boundary or pull slash back into the thinning unit. Protect property corner and bearing trees. Fall trees away from, or pull slash back from the topgraphic break into Basin Creek along the west-southwest boundary.

Crop trees should exhibit the best growth for the past three years, have good form and color, be relatively free of insects, disease or mechanical damage. Refer to Desirable leave tree characteristics C.2. Ignore WP (“ghost” tree), do not leave as a crop tree, do not cut unless it is within 5 feet of a crop tree. Clear the road prisms of thinning slash (see project work map).
