APPENDIX B TIMBER REMOVAL SPECIFICATIONS AMENDMENT 8 Malheur NF 10-year Stewardship Project

SOLICITATION AG- 04KK-S-13-9000

1. The end result is to reduce the risk of severe wildfire by reducing surface fuels, ladder fuels and crown bulk density. Also the goal is to maintain a vigorous, healthy stand of trees which will provide good visual quality and a future late/old structural stage of stand development.

Timber in the following units is Designation by Prescription (DxP). Refer to the Prescriptions and the Timber Removal Guidelines provided.

Units: All units in the MD subdivision 7224 Acres

Generally:

· Leave all trees 21.0 inches DBH and greater.

· Trees less than 7” DBH will be considered timber subject to agreement.

· For Basal area spacing refer to project area map (Basal Area Table) and the Basal Area variability Table at the end of this prescription.

· Species preference WL/PP/DF/LP/WF/GF.

· Leave all hardwoods.

· Leave dominant and co-dominant conifers.

· Leave conifers with crowns that do not touch.

· Leave snags standing. If they must be felled, they will be retained in place.

· Trees < 21” DBH shall be removed within 2 times the drip line of trees over 21” DBH, and that do not exhibit “Old Growth Characteristics”

· Trees that have a common stump should be either both cut or both left. If left, they shall be treated as a single tree for spacing.

· Wildlife areas will consist of unthinned areas, clumps, small diameter material, and Rocky areas.

· “Wolfy” trees, trees with poor form, broken tops or numerous large limbs will not be cut. Typically these trees are not of commercial value.

· Trees with cavities will not be cut.

· See definitions for protection of Mountain Mahogany.

· Aspen trees, stems, or sprouts shall have trees less than 21” DBH removed: 1) south side to 150 feet, 2) east and west side to 100 feet, 3) north side to 66 feet. These areas shall also be mapped and given to the COR.

· Provide a 50 foot buffer on all known populations of Cordilleran Sedge.

· Less than 5% of leave trees shall show mechanical damage.

· Stump Height is 12” or less

· Leave all trees within 150 feet of springs, bogs, seeps, or elk wallows.

· 1-4 clumps/ac of 3-6 trees greater than 12” DBH within an approximate area of 20 feet by 20 feet.

When a contractor begins work in any of the MD units, the contractor will sample mark 3 units with 5 acres each. This mark will be approved in writing by the COR before any felling of trees takes place. Leave Tree Marking (LTM) will be completed with Orange paint.

Basal Area Variability Table Crown Spacing in feet (range plus or minus 25%)

Bole Spacing in feet

The variation in basal area retention is Range 40-70 Basal Area for the 50 BA prescription and 60-80 variation for the 70 BA prescription.
