1 TNF WATCH LIST BOTANICAL SPECIES 1.1 INTRODUCTION The Tahoe National Forest (TNF) maintains a watch list of botanical species (plants, lichen, and fungi) that of conservation concern, but have not been designated as Forest Service Sensitive (FSS) by the Regional Forester. This list includes species that are newly described; locally rare; range extensions or disjunct populations; plants of specific public interest; or species with too little information to determine their appropriate status. These species make an important contribution to forest biodiversity and should be protected under the provisions of the National Forest Management Act (NFMA) (1976). According to the Regional Forester, Watch List species should be considered during project planning with corresponding documentation maintained in the planning file (USDA Forest Service 2006).

The purpose of this section is to document consideration of TNF Watch List species that may be impacted by activities proposed in the Yuba project. If necessary, it may also contain recommended protection measures to prevent Watch List species from being elevated to the Forest Service Sensitive species list. The project is described in detail in the Yuba Project Environmental Assessment.
1.2 SUMMARY OF ANALYSIS PROCEDURE The following table provides an outline of the analysis procedure used to analyze the effects to Watch List Species.

1.3 PROJECT COMPLIANCE
1.3.1 Survey adequacy
Other Botanical Resource Assessment—Yuba Project
Page 3 of 7
Most of the project area was surveyed and surveys targeted TNF Watch list species. Of the approximately 7114 AC where project activities are proposed in the Yuba Project, there are NRIS survey records for 3324 AC—all of which occurred in 2015. Additional surveys were conducted in 2010, but there are no spatial data for these areas because, on TNF, spatial NRIS records only exist for surveys that occurred in 2014 or later. For the Yuba Project, all areas where ground-disturbing activities are proposed have been surveyed. There are a few additional areas where ground disturbance may be required (e.g. temporary roads, landings); there are management requirements in place to survey these areas prior to implementation and protect any new occurrences. Some areas where only under burn is proposed (~890 AC) were not surveyed as this treatment does not include ground disturbance and is not anticipated to have long-term negative impacts on rare botanical species. Surveys are considered adequate for the Yuba Project.
1.3.2 TNF Watch List occurrences in project area There are four TNF watch list species known in the project area. There are 14 occurrences consisting of 15.81 AC. Maps of occurrences and units are included in APPENDIX A.

1.3.2.1 Epilobium howellii (Yuba Pass willowherb) This perennial forb is restricted to the Sierra Nevada from Sierra to Fresno counties (California Native Plant Society 2016). It grows in margins of moist meadows and mossy seeps in subalpine coniferous forest. Overall trend for the species is stable, with over 90 occurrences extant across its range (California Native Plant Society 2016). It was removed from FSS list in 2013 because several new occurrences were documented and it now appears to be less rare than previously thought. On the TNF, it is known from nine occurrences. Threats due to management activities include heavy livestock grazing and trampling, road maintenance, off-highway vehicle use, and any other activity that would alter the flow or amount of water in wet meadows and mossy seeps.

Occurrences are generally small. Overall trend for the species is stable, with over 30 occurrences extant across its range. It was removed from FSS list in 2013 because several new occurrences were documented and it now appears to be less rare than previously thought. On the TNF, it is known from only three occurrences—two of which intersect the project area. Threats from management activities are any activities that modify fen habitat, specifically hydrologic changes that

Species identification to species can be challenging and several species have not been described; therefore, all Sphagnum species are protected until identification can be confirmed. Sphagnum spp. plays an important role in regulation of the water table and chemistry in fens. Threats from management activities are any activities that modify fen habitat, specifically hydrologic changes that may cause drying; late-season grazing, off-highway vehicle use and off-trail recreation are persistent pressures on fens.

There are 31 occurrences in California alone (California Department of Fish and Wildlife 2016). It grows in red fir forest in moist areas/shaded edges of creeks at elevations that range from 5,200-6,600 feet(California Native Plant Society 2016). On TNF, it is known from 15 occurrences. Overall trend is unknown. Threats have not been formally identified.

1.3.3 Project impacts to watch list species Ground disturbance and tree felling associated with harvesting, thinning (mechanical), and associated activities (e.g. machine piling) as well as temporary road / landing construction, road reconstruction and road decommissioning has the potential to negatively impact TNF watch list species through direct physical damage or death of individual plants or indirectly by altering habitat. Additionally, under burning while plants are actively growing may result in scorch or death. To address these impacts, management requirements was added to the project that require surveys of unsurveyed ground disturbance prior to implement, prohibit ground disturbance & tree felling in TNF watch list occurrences, and restrict burning to the dormant season.
1.3.4 Project management requirements relevant to watch list species • MMR-BOT1: Special status botanical occurrences (T&E, FSS, TNF Watch list) will be flagged and avoided for all ground
disturbing activities with a buffer of 100 feet (Units 07, 14, 20, 23, 34, 58, 82, 102, 103, 104, 106, D). Trees will be felled away from known occurrences. All TES botanical species occurrences will be flagged prior to implementation and indicated on project maps.
• MMR-BOT2: Proposed road construction, reconstruction, landings and staging areas in potential habitat for TES botanical species will be designed and marked on the ground only after the areas have been surveyed by a qualified botanist in the proper season.
• MMR-BOT5: Burn piles will not be placed in known special status botanical occurrences. Fireline will be placed at least 100ft from known occurrences. Under burn is allowed in occurrences when special status species are dormant, except for Lewisia kelloggii. No ground-based prescribed burn activities will occur in Lewisia kelloggii occurrences (A, C, D, G). No ground based prescribed burn activities will occur in Unit B 1.
Unit-specific requirements are outlined in the project’s botanical resource protection plan (APPENDIX B)
2 SPECIAL STATUS PLANT COMMUNITIES 2.1 INTRODUCTION The Sierra Nevada Forest Plan Amendment (SNFPA) directs the Forest Service to address “fens and bogs” as Special Aquatic Features during project analyses and to maintain, restored, and/or enhance fens on National Forest System (NFS) lands (USDA Forest Service 2004b). Fens are ground-water dependent wetlands that are hotspots of biological diversity and provide habitat for rare plants such as Meesia, Sphagnum, and other bryophytes. Fens are generally delineated by their substantial peat accumulation in the soil profile; in the Sierra Nevada, areas that contain a minimum of 40cm of organic (peat) soils within the upper 80cm of the soil profile are generally considered fens (Cooper and Wolf 2006). Fens are among the most sensitive plant communities identified during ecological assessments of the Sierra Nevada (Millar and others 1996; USDA Forest Service 2004b). As of 2016, there are currently 49 fens known on TNF.
2.2 PROJECT COMPLIANCE The analysis procedure used for Watch List species is also used for uncommon plant communities (Section 1.2). The project area was surveyed for special status plant communities. No fens were
Other Botanical Resource Assessment—Yuba Project
Page 6 of 7
documented. However, peat development was noted in several meadow units (101-107, 114). Fens have formed through long-term aggregation of peat (Vitt 2000). Peat accumulates very slowly, on the order of 11 to 41 cm per thousand years in the Rocky Mountains (Cooper 1990, Chimner and Cooper 2002). So even peatlands that do not meet the fen criteria (40 cm peat) can be very old and highly sensitive to hydrologic change. To protect the fen development process, a management requirement was added to the project to prohibit ground disturbance in peat soils.
2.2.1 Management requirement relevant to special status plant communities • MMR-BOT4: No ground disturbance will occur in peat-dominated soils, unless critical to restoring hydrologic function
(Unit 101-107). Unit-specific requirements are outlined in the project’s botanical resource protection plan (Appendix B)
3 SPECIAL MANAGEMENT DESIGNATIONS 3.1 INTRODUCTION As part of land and resource management planning, TNF has designated certain areas for special management and listed others for consideration for special management.
3.1.1 Research Natural Areas The intent of the Research Natural Area (RNA) System is to preserve a representative array of all significant natural ecosystems and their inherent processes as baseline areas (USDA Forest Service 2004a). For lands in the RNA System, the resource management emphasis (Management Areas 016, 100, is to protect and preserve the natural ecological features (USDA Forest Service 1990). There are three RNA on Tahoe National Forest (Table 5) (USDA Forest Service 2004a).

Management Area
Acres Target Element
Babbitt Peak Sierraville 016 1,747 Washoe pine & mountain mahogany Lyon Peak / Needle Lake American River 100 700 mountain hemlock Sugar Pine American River 085 640 mixed conifer forest
3.1.2 Special Interest Areas Special interest areas (SIA) can be designated to recognize a broader range of values than research natural areas, including botanical resources. While there are eight SIA designated on TNF, there is only one botanical SIA—Placer County Big Trees Grove (356 ac, American River Ranger District). The resource management emphasis is to protect the botanical features (Management Area 107) (USDA Forest Service 1990).
3.2 PROJECT COMPLIANCE Based upon a review of TNF GIS data, there are no special management designations for botanical resources in the project area.
