Installed plugs in eroded creek channel, brought water table up 3-4 feet in lower end of Sardine Valley Tree density reduced from 412 to 106 trees/acre Canopy reduced from 63% to 33% Average tree spacing reduced from 10 feet to 20 feet Rate of spread, Flame Length, Reaction Intensity, Heat per unit area and Fire line intensity all effectively reduced Some areas appeared to have fewer large logs than desirable, but there were few logs present prior to treatment Shortcomings and Successes: Successful implementation of a DFPZ – met stand restructuring objectives and fuels objectives are expected to be achieved after implementation of the follow-up underburn. The Bits project was implemented under Sierra Nevada Framework 1, which did not allow the removal of trees greater than 20” in diameter. If implemented under Framework 2, the project may have been able to be sold as a timber sale and contributed money to the federal treasury, instead of put out as a service contract, consequently using taxpayer dollars. Implementation under Framework 2 would have allowed inclusion of additional sawlogs 20 – 30 inches in diameter, and would have made the project more economical. The district learned that flagging boundaries of groups was not satisfactory alone. Group selection boundaries need to be tagged and marked with GPS units as well. The group discussed the apparent lack of large woody material in some portions of Bits Unit 36. There were few logs present prior to treatment, so it is difficult to create logs. As an alternative, the group discussed maintaining some grapple piles or doodles to provide potential habitat for rodents and medium sized mammals. California Waterfowl Association was interested in the Plug and Pond projects and saw the ponds and associated habitat as providing important waterfowl nesting habitat. Follow up actions: Implement planned underburns to meet fuels objectives. Retain large wood, some grapple piles and doodle piles to provide habitat for rodents and medium sized mammals in lieu of the non-existent large logs. Attempt to preserve some piles where it does not constitute a fuels hazard. District Ranger: /s/ Sam J. Wilbanks___ Date: 6/12/2007 Appendix 1. Project handout distributed to field trip participants. Scraps Project Sierraville Ranger District Project Objectives and Prescriptions (Scraps Project EA pgs. 1-14): The alternative selected specifically would be more effective than the No Action alternative in reducing negative effects from catastrophic wildfire, providing a safer fire suppression environment, connecting links to existing fuel breaks in adjacent area, creating the pre-conditions necessary for reintroducing fire to the ecosystem, beginning the process of restoring fire to its natural role in the ecology of the area. The thinning and underburning are proven methods for reducing density in fuel ladders and ground fuels. In addition, the thinning from below and group selection harvest included in selected alternative would be more effective in improving timber stand health, vigor, and resistance to fire, insects and disease, and increasing diversity of age classes with forest vegetation types. This alternative would contribute more than the No Action alternative to economic activity, income, and employment, which could support economic stability in local rural communities, and also more toward implementing the Herger-Feinstein Quincy Library Group (HFQLG) Forest Act and Pilot Project. A variety of cost effective methods, including timber sales, service contracts and Forest Service crews were used in response to site-specific conditions, to achieve the project objectives. Bits #36 Prescription: Thin stands mainly from below at approximately 21 foot spacing to retain about 100 trees per acre. Harvest trees less than 20 inches DBH; Retain a minimum of 30% canopy closure. Retain all snags greater than 15 inches DBH. Follow up treatments, including grapple/hand piling and burning, under burning or a combination of those methods would be implemented to reduce and rearrange excessive surface fuels.

Proposed treatments would insure that fuels would be heterogeneous and discontinuous for approximately 5 to 10 years following implementation. After approximately 5 to 10 years fine surface fuels would become more continuous due to needle drop from residual trees but any fire should be a low intensity surface fire.

These activities would reduce active erosion within the watersheds, reduce the potential for future erosion, improve the quality of surface runoff by improving surface filtration, restore floodplain function on portions of Merrill and Davies Creeks, increase flood attenuation potential, increase seasonal ground water storage and will improve and increase the riparian habitat in the area. The nature of this type of restoration work requires work within the floodplain of Davies and Merrill Creeks. The following sites have been identified as benefiting from restoration work: Site 2: Davies Creek: A railroad grade was constructed in the late 1920s in the channel and floodplain for almost a mile. The construction of the grade rerouted the natural stream flow, disrupted the flood flows on the floodplain, and caused the stream to erode a large gully that is still actively eroding. The railroad grade and the existing road impact two alluvial fans on tributaries to Davies Creek. At this site the proposal is to (site 2 diagram in Appendix A): Site 5: Davies Creek from the lower end of Sardine Valley to Stampede Reservoir: A railroad grade was constructed following Davies Creek in the 1920s. Some of the grade was constructed in the channel and on the floodplain and has redirected and confined flows of the creek in several places. The railroad grade construction caused a loss and degradation in riparian habitat, has caused the stream to downcut in several places, and has created headcuts that have eroded up into the lower end of Sardine Meadow. In turn this has caused a lowering of the meadow water table and a loss of meadow habitat. The channel system is still actively eroding. Additionally, the existing road at the bridge site has constricted the flood plain of Davies Creek. The proposal for this site is (diagram for Site 5 in Appendix A): a. Re-direct the flow of Davies Creek from the existing incised eroding channels in lower Sardine Valley into stable remnant channels on the meadow surface where the stream can access the floodplain. b. Close off 1000 feet of the incised channel using gully plugs at lower end of Sardine Meadow to stop the active erosion and raise the water table. Small ponds would be excavated along the side of the closed stream segment to generate material needed to construct 6 plugs to close off the gully. Material excavated for plug construction totals about 1000 cubic yards for the 6 plugs (about 167 yards per plug). Some material may be obtained from the RR grade removal. No disturbance would occur in the remnant channel where the water will flow. Disturbance would cover from 1 to 1.5 acres c. Remove approximately 150 of railroad grade fill and rebuild the creek elevation for 300 feet at the bottom of Sardine Valley using material removed from the railroad grades. An eroded portion of channel would be reconstructed with rock and earth and re-vegetated. This will create a riffle/pool system that maintains fish passage. Disturbance will be less than ½ acre. d. Remove 7 short sections of railroad grade (1300 feet total) between Sardine Valley and the Davies Creek Bridge that are currently confining the flows of Davies Creek and causing the creek to scour. Disturbance will be approximately ½ acre. e. Add 3 to 4 culverts to the County road system in the approaches of the existing bridge to facilitate flood flow of Davies Creek underneath the road. The culverts will be installed at floodplain elevation to increase flood capacity at the bridge. Site 5 continued: f. Return Davies Creek to its original channel below the bridge. g. Use plugs to close off the railroad ditch that now carries stream flow below the Davies Creek Bridge. 9 plugs will be needed for a total of approximately 1300 cubic yards. Most (approximately 60%) of the material will come from the railroad grade described in h below. The remainder of the fill will be moved from site 6 below or excavated from the abandoned channel and will make some of the ponds larger. h. Remove 1000 feet of railroad grade below the bridge. Material removed from the grade will be used to create plugs in the channel as described in g above. Disturbance from g & h combined will be approximately 1 acre. i. Remove trees along the railroad grade as needed to complete restoration work. j. Returning Davies Creek to its original channel will cause the existing vault toilet and 4 campsites in the Davies Creek Campground to be within the floodplain. The toilet vault and the four affected campsites will be re-located to a location just above the existing campground and well out of the floodplain. k. Create an interpretative site near the Davies Creek Campground where the road intersects with a historic railroad grade. Signs would describe the historical railroad system and why it was removed (in order to restore the creek function).
