This seed mixture is for treating all disturbed areas and areas cleared for fuel reduction purposes. Seeding application rates are specified on a “pure live seed” (PLS) basis. All seeds should be thoroughly mixed and seeded together at the same time. Drill seeding is recommended where feasible. Drill rows should be spaced as 12 inches apart and seed should be planted at a depth of 1/2 inch. Broadcast seeding is recommended for rocky, steep, or small treatment areas. The seed can be broadcast using hand held seeders such as a “Whirlybird” or a broadcast seeder mounted on an ATV. Continually mix the seed while seeding to equally distribute the small seeds throughout the mix. Following the broadcast seed application, seeded areas should be lightly raked to assure seed placement at an average depth of 1/2 inch. This can be done with hand held rakes, or by pulling a harrow implement or piece of chain link fence behind a truck or ATV in areas that are less rocky.
These guidelines are provided as overall recommendations. However, site-specific evaluation of the treatment areas by a specialist from a land management agency, the Natural Resources Conservation Service, or the University of Nevada Cooperative Extension will provide even greater assurance for success.
Thin Jeffrey Pine trees to reduce the stocking level to between 60 and 80 square feet of basal area per acre. Basal area of a tree is defined as the cross–sectional area at breast height (4.5 feet above the ground) and is expressed in square feet. A guide for the spacing needed for 80 square feet of basal area is, multiply a trees diameter breast height (in inches) by 1.7. The product will be the spacing in feet you should have between another tree of the same size. The following is a chart of tree sizes and the spacing needed between trees of the same size.
