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 at 12 inches apart and seed should be planted at a depth of 1/4 to 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. Following the broadcast seed application, seeded areas should be lightly raked to assure seed placement at an average depth of 1/4 to 1/2 inch. This can be done with hand held rakes, or by pulling a drag or piece of chain link fence behind a truck or ATV in areas that are less rocky.
Ponderosa Pine Tree Thinning Guide
Thin ponderosa pine trees to reduce the stocking level to 80 to 100 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. The following is a chart of tree sizes and the spacing needed between trees of the same size.
| Tree Diameter at 4.5 feet high (inches) |
Basal Area | |||
|---|---|---|---|---|
| 60 sq ft Dia. X 2 |
80 sq ft Dia. X 1.7 |
100 sq ft Dia. X 1.5 |

- Remove the trees with forked tops. Forked topped trees can be become a hazard, as part of the top could fail and damage buildings, cars, and people.
- Remove trees with basal scars that are showing signs of wood boring insects and ants in the bole of the tree.
- Remove trees with dead or broken tops. These trees will attract bark beetles.
- Remove trees that are infested with dwarf mistletoe. If a tree only has dwarf mistletoe in the lower branches, then prune the branches off. Dwarf mistletoe is a parasitic plant that spreads by seed and will eventually kill the tree.
- Remove the smaller trees that are not in a dominant position in the canopy and are being crowded by the taller trees. Remove enough trees to all for ten to fifteen (10-15) feet of space between crowns. Ponderosa pine need direct sunlight to survive. Trees in a shaded condition will slowly die from lack of sunlight, but until they die, they will continue to use moisture and nutrients the larger trees could use. This stress for moisture in a overstocked condition will predispose all the trees to attacks from bark beetles, especially during years of drought.
- Treat the stumps with borax powder (decca hydrate borax) to prevent harmful root rot fungi (Fomes annosus ) from becoming established.
- Thinning debris (limbs, tops and tree trunks) should be promptly removed from the site. Ips beetles will breed in wood larger than three (3) inches in diameter if the wood and slash remain on the site longer than four weeks. If the homeowner wants to keep the wood to burn in a fireplace, then the wood should cut to the proper length and split to help dry it out. Do not stack the wood between trees, next to buildings or under decks. Dispose of the limbs and tops by burning or chipping and hauling the chips away.
