4. Data Recording:

• Cruise data shall be recorded on R6 cruise cards, supplied by the Forest Service.

5. Volume, Value, and Sampling Error Reporting:

• After acceptance of cruise data from the Contractor, the Forest Service will input and process cruise data using either the National Cruise Program (NATCRS) or the regional computer

Page 8 of 25 Bly Ranger District programs established by the Regional Forester for calculating and reporting the results of timber cruises.

• Following processing, the Forest Service will notify the Contractor if the cruise meets Maximum Sampling Errors for the Sale-as-a-Whole (less than 30%) and strata error (less than 40% error).

I. When the original cruise exceeds the desired sampling error and a small number of additional samples are needed to reduce the error to an acceptable level, the Contractor will return to a pre-determined number of count plots and collect tree measurements at each. Corrective action and additional samples will be agreed to by Forest Service.

When Final Cruise for each Timber Treatment Area has been completed and accepted, the FS will complete an independent Timber Sale Appraisal using the R6 TEA appraisal system following the Forest Service Handbook direction, to determine the Advertised Timber Rate and Bid Premiums to be collected according to the “Timber Appraisal and Bid Premium” notes section in the solicitation. Maps, plans, and quantities accepted from Item 4, 5, 6, 7, and the final cruise volumes determined from Item 8(b) WILL be used for appraisal data entries to calculate logging costs.

There shall be mutual agreement between both parties to modify gross tons of sawtimber and set the contract timber rate with a bi-lateral modification to execute Optional Work Items. If an agreement of the appraised Minimum Acceptable Offer timber rate cannot be made within 14 business days from the date the appraised timber rate is shared, Grizzly Commercial Thin Units, optional service work and road maintenance associated with Grizzly Project Area will not be executed, and a bi-lateral modification will not occur.

Included in the bi-lateral modification will be any revisions related Grizzly project areas in Appendix A, Appendix B Timber Specifications in its entirety associated with timber removal and Appendix C in its entirety associated with road maintenance.

Small-tree thinning will be the sole treatment on 650 acres, while both large- and small-tree thinning will occur on 170 acres.

Large-tree thinning – Cut and deck/pile where sawtimber size trees meeting Appendix B A.2 specifications cannot be removed from the Contract Area.

Perform these in order; subsequent objectives do not override any before them:

1) Retain all hardwoods, five-needled pine, mature trees (see C2.355# in Appendix B), ponderosa pine and incense-cedar ≥26” DSH, and orange-marked trees.

2) Remove all western juniper >2” DBH.

4) Within 50 feet of an aspen clump, thin to 30 square feet per acre basal area, with an acceptable range of 20-

40 sq. ft./acre. Five-needled pine and ponderosa pine ≥ 26” DSH count towards residual BA within these buffers.

5) Where current conditions are at ≤ 20 square feet per acre basal area of ≥ 26” DSH ponderosa pine, thin stand to a target basal area of 50 square feet per acre with an acceptable range of 30-70 square feet per acre, not counting ≥ 26” DSH ponderosa pine towards target basal area. Where current conditions are at ≥ 30 square feet per acre BA of ≥ 26” DSH ponderosa pine, thin stand to a target basal area of 30 square feet per acre with an acceptable range of 20-50 square feet per acre, not counting ≥ 26” DSH ponderosa pine towards target basal area. Because this is the last objective in this list, previous objectives can override this requirement.

2) Cut all western juniper >2” DBH.

3) Cut all sub-merchantable trees within the dripline of a healthy, mature ponderosa pine (see
