APPENDIX A

SOUTH RIM HAZARD TREE STEWARDSHIP

Contract Item and the associated cutting units for non-sawlog harvesting are listed in the table below.

Specific details designating Included Timber and Timber Subject to Agreement are described in the treatment descriptions in subsequent sections, and in Appendix B.

*Estimated Acres/Miles – All measurements are horizontal distance calculated in gis from gps surveys, remote digitizing from LiDar data and/or digital orthophotos. Hazard tree removal acreage was estimated based on a 200 foot distance from the road centerline; however, actual area will vary based on tree size.

**Tonnage – A conversion factor of 1 ccf = 1.71 tons was used.to estimate quantity (tons) of material to be removed. Unit tons of biomass for removal were based on total tons by treatment, distributed by estimated acres of the unit. Actual amount of material per unit may vary. Volume (ccf) was calculated from an acre based cruise or a dimensional conversion (for decks). Payment will be based on actual amount of material removed.

Table 1. Stewardship Service Items. Mandatory and Optional Stewardship service items by Unit, treatments and estimated amount. Optional Items will become mandatory if awarded to contractor at the discretion of the Forest Service based on bid price.

ACTIVITIES REQUIRED FOR STEWARDSHIP CONTRACT ITEMS

1 Treatment Unit Boundaries: Treatment Units are identified on Contract Area Map. Fuel Treatment Unit boundaries are designated by Blue and Yellow flagging along unit perimeter. Boundary corners (where meeting a forest system road or private property boundary) are double flagged and most often identified with cutting unit number on the flagging. Private property boundaries are designated with red flagging and/or with metal signs.

1.1 Biomass Removal unit boundaries are designated by White flagging along unit perimeter. Boundary corners (where meeting a forest system road) are marked by pink tracer paint showing two vertical dots facing into the unit and vertical lines facing the boundary line. Biomass Removal treatments are described Appendix A (4.4) and Appendix B.

1.2 Hazard tree removal unit boundaries are marked by pink tracer paint, showing a vertical line facing into the unit and vertical lines facing the boundary line, where the unit starts and stops along designated sections of road.

Additional white flagging is in place adjacent to the painted boundary. The width of hazard tree units are variable based on the size of the designated tree. Hazard tree designation removal requirements are described in Appendix A (4.4) and Appendix B.

2. Fuel Treatment Unit Trees Designated for Cutting: Subject to conditions identified below in 2.1, 2.2 and 2.3, within specified Fuel Treatment and Biomass Removal units (cutting units) identified in Table 1 and shown on the Sale Area Map, the Contractor shall cut all dead (no green needles) or dying trees (at least of 2/3rd of crown actively fading from top down or 3/4 of the circumference of the bole has successful bark beetle attacks) 3 inches DBH through 39.9 inches DBH within specified units. Additional trees to be cut, if any, are Marked with blue or green paint. Cutting unit boundaries and other trees that shall be left uncut are marked with pink, orange, or red paint. Minimum specifications of Included Timber & Timber Subject to Agreement for Removal are identified in Division A of Appendix B. All designated trees within removal areas are required to be removed as included timber as described in Appendix A 4.4. If a tree marked for retention is a hazard to operations, the tree may be felled, limbed, topped and left in place. When it is necessary to delete previously marked trees, a unique tree marking paint color such as black will be marked over or adjacent to the original mark. Any black tracer paint cancels the previous paint color.

2.1. Leave Trees: The contractor shall not fall or remove any tree marked with orange, pink, or red tracer paint above and below stump height, oaks greater than 12 inches dbh, hardwoods located near seep areas, or trees otherwise designated for retention.

2.2. Oak Treatments: When removing oak snags Contractor shall minimize damage to oak sprout by leaving 1/3- ½ of sprouts undamaged.

2.3. Snag Retention: Retain conifer snags at 4-6 trees per acre of the largest trees and all trees over 40 inches dbh.

3. Hazard Tree Treatment Unit Trees Designated for Cutting. Within specified Hazard Tree Treatment Units listed in Table 1 and shown on the Contract Area Map, the Contractor shall cut all dead (no green needles) or dying trees (at least of 2/3rd of crown actively fading from top down or 3/4 of the circumference of the bole has successful bark beetle attacks) 3 inches DBH or greater within 1.5 tree lengths from open National Forest system road. Additional trees to be cut, if any, are marked with blue or green tracer paint. Cutting unit boundaries and other trees that shall be left uncut are marked with pink, orange, or red paint. Minimum specifications of Included Timber & Timber Subject to Agreement for Removal are identified in Division A of Appendix B. All cut material meeting minimum specifications identified in Division A of Appendix B is required to be removed as included timber as described in Appendix B. If a tree marked for retention is a hazard to operations, the tree may be felled, limbed, topped and left in place. When it is necessary to delete previously marked trees, a unique tree marking

South Rim Hazard Tree Stewardship – Appendix A Page 5 of 6 paint color such as black will be marked over or adjacent to the original mark. Any black tracer paint cancels the previous paint color. Hazard trees shall be felled in accordance with Appendix A (4.2) Falling Specifications.

4. Treatment Specifications

4.1.3. Fall and Lop 46% and greater slopes – Falling and lopping limbs and tops from trees designated for cutting on slopes greater than 46% with the objective of concentrating fuels in selected locations for future treatment by the Forest Service (jackpot burning). Falling methods shall only include manual methods Appendix A (4.2).

4.1.4. Optional Piling 46% and greater slopes – Within areas where falling and lopping treatment occurred on slopes 46% and greater, hand piling shall occur with the objective of concentrating fuels for future disposal by the Forest Service. Piling shall be done in accordance with Appendix A (4.3).

4.2. Falling Specifications:

4.2.1. Mechanized Felling Requirements: Operation of mechanized equipment shall be limited slopes 35% or less. Operation of low ground pressure equipment (<10 psi) is allowable on slopes 45% and less.

4.2.2. Manual Felling Requirements: Manual felling is acceptable on all slopes. In areas with slopes 46% and greater, manual felling (hand felling) is the ONLY acceptable method.

4.2.3. Directional Felling: Trees designated for cutting, Included Timber and other material to be cut shall be directionally felled away from system roads, lava caps, meadows, hardwoods, fences, gates, cattle guards, power lines, survey monuments, control areas, reserve trees, sensitive plants, noxious weed sites, stream courses, NFS trails and other ownerships. Such directional felling shall not be required when in the faller’s judgment it is unsafe to do so.

4.3. Piling Specifications:

4.3.1. Material required to be Piled- Fuel Treatment Units: All felled trees, associated material (slash), and existing down material greater than 3 inches diameter and 3 feet in length shall be piled in accordance with specifications listed in Appendix A - 4.3.3, 4.3.4, 4.3.5, 4.3.6 and 4.3.7 or otherwise removed. On slopes > 45% where removal of material is not possible, felled trees shall be limbed and topped at 8 inches in diameter and only limb and top material shall be required to be piled.

4.3.2. Material required to be Piled- Hazard Tree Treatment Units: Within Hazard Tree Treatment units, piling is only required if the Hazard Tree Removal option is awarded.

4.3.3. Pile Standards: Piles shall be tight and as free of dirt as possible. Piles that contain more than 10% dirt will require rebuilding. Unless otherwise agreed, piles shall be located at least 50 feet from: the nearest live tree, retained snags, stream courses, and control areas.
