Carlson, Forest Supervisor Mendocino National Forest 825 N. Humboldt Avenue Willows, California 95988 For Information Contact: Frank Aebly, Ph.D. District Ranger Mendocino National Forest, Covelo and Upper Lake Ranger Districts 10025 Elk Mountain Road Upper Lake, California (707) 275-1401 2 Abstract Current conditions The Pine Mountain Late Successional Reserve (LSR) is one of the smaller LSRs within the Forest but provides an important link between the Blue Slides LSR seven miles to the southeast and the Sanhedrin LSR, 1.25 miles to the north. The Pine Mountain LSR also provides a critical link to State and other Federal lands to the south and west. It is the last remaining largest southernmost functional patch of late successional habitat in the Inner California Coast Range of California. The area is currently part of Northern Spotted Owl Critical Habitat (Unit 11, Subunit ICC 5), a land allocation designated by US Fish and Wildlife Service, and also includes 1.6 miles of critical habitat for anadromous fish. These habitats are located within both the LSR and matrix lands. However, the LSR is suffering from overstocking and crowding of trees across a range of diameters. In the majority of the LSR small diameter trees (< 10 inches diameter breast height) are the main problem. Due to past management activities the forest is so dense that walking through it is almost impossible and the quality of habitat is declining. In other areas trees across a range of diameters are very dense and present ladder fuels problems that threaten the overstory canopy. A wildfire in the project area would likely result in large contiguous areas of habitat loss rather than small patches that would have occurred in historic times. We observe an alteration of species composition shifting toward a majority of shade tolerant species, such as Douglas-Fir, a decrease in biodiversity, declining forest health and resiliency to inherent disturbances, such as fire, insects, and disease. Density related tree mortality is occurring over large areas and the susceptibility to drought-induced tree mortality, because of intense between tree competition for resources (light, nutrients and water) is increasing. Ecological consequences of past land management practices also include: diminished late successional habitat for wildlife including the northern spotted owl; increased forest stand density with low-level growth and/or vigor; increased susceptibility of forest stands to insects and disease; changed species composition of forestlands, grasslands, chaparral, and oak woodlands; habitat alteration of forestlands, chaparral, oak woodlands, and grasslands (i.e. loss of biodiversity); and Increasing probability of larger more intense fires (Perry et al. 2011). Future Desirable Conditions Future desirable conditions as described in the Mendocino National Forest Land and Resource Management Plan (LRMP 1995) include an increase of northern spotted owl (NSO) habitat as well as increased habitat for species that depend on late seral forests. Additionally, future desired conditions include a decrease in the size and intensity of wildfires, and a decrease in the potential for stand replacing losses from major outbreaks of insects such as pine beetles and diseases. The Pine Mountain Late Successional Reserve Assessment (USDA 2000) identifies the project area as having a history of frequent, low-intensity fires which is desirable to maintain healthy ecological conditions. Most of the recent larger fires within the project area, have included a high proportion of acres burned at higher intensity than desired (USDA 2000). This is most likely due to a departure from the natural fire return interval. The LSRA rates fuels hazard, within the project area, as 3 moderate, however the current project analysis for the project area rated this area as having a high fuels hazard (Fire and Fuels Report, USDA 2016c). Future desirable conditions are a reduced fire hazard rating. Purpose and need The primary purpose of the proposed Pine Mountain Late Successional Reserve Habitat Enhancement and Protection project is to protect and enhance late successional habitat by putting the landscape on a trajectory where characteristic fire regimes and processes can return and ecological processes are restored. Silvicultural treatments (including prescribed fire) are being proposed to reduce stand density and increase the quality and amount of late successional habitat by increasing species diversity and average tree size. By reducing stand density, between-tree competition for resources will be reduced and the remaining trees will be more resilient to fire, insects, and disease. The remaining trees will also be more resilient to drought and warmer drier periods which are anticipated due to climate change (IPCC 2014). Treatments are also being proposed to reduce ladder fuels to lessen overstory mortality in the event of a wildfire and to better protect the LSR from fires entering from the west and southwest. As stated in the Northern Spotted Owl Recovery Plan (2011) federal land managers need to be maintaining or improving ecosystem resilience in the face of climate change. Resilient forests are those that not only accommodate a gradual change related to changes in climate but also tend to return toward a prior condition after disturbance either naturally or with management assistance (Millar et al. 2007). Managing for resilient forest conditions should be considered a fundamental recovery goal for norther spotted owls. Federal land managers should apply ecological forestry principles where long-term northern spotted owl recovery will benefit, even if short-term impacts to spotted owls may occur (Franklin et al. 2007, USDI FWS 2007). There is a need to implement actions consistent with the LRMP, LSR assessment, and Spotted Owl Recovery Plan guidelines to reduce the probability of large scale loss of Late Successional Habitat and protect this vital link between other areas of Late Successional Habitat. The LSRA also identifies areas with high road densities that fragment wildlife habitat. Roads can also affect the natural hydrologic flow path, and, if not designed and maintained properly, can lead to significant erosion and mass wasting problems. There is an opportunity within this project to decommission or close roads that are no longer needed, and storm proof ones that will receive future use. There is a need to develop and manage a transportation system that minimizes the impacts of roads on the landscape. Treatments are being designed to accomplish the following Purpose and Need objectives: 1. Enhance habitat for the northern spotted owl and associated late successional species. 2. Reduce the risk to late-successional habitat loss from wildfire through vegetative treatments designed to modify and restore characteristic fire regimes and forest structure. 3. Improve forest health, vigor, and resilience to fire, insects and disease as well as enhance the diversity of plant and animal habitat found within the project area 4. Manage National Forest lands (including roads and trails) to meet the Aquatic Conservation Strategy Objectives and direction set forth in the Mendocino National Forest Land and Resource Management Plan (LRMP). 4 Based on the guiding principles from the LSR assessment, this project is designed to achieve the objectives and facilitate ecosystem restoration for a more sustainable future condition. To Provide Comments: The Pine Mountain LSR Habitat Protection and Enhancement Project Draft Environmental Impact Statement (DEIS) is available online at the Mendocino National Forest website: http://fs.usda.gov/mendocino. Reviewers should provide the Forest Service with their comments during the review period of the DEIS. This will enable the Forest Service to analyze and respond to the comments at one time and to use information acquired in the preparation of the final environmental impact statement, thus avoiding undue delay in the decision-making process. Reviewers have an obligation to structure their participation in the National Environmental Policy Act process so that it is meaningful and alerts the agency to the reviewers’ position and contentions. (36 CFR 218.5) Environmental objections that could have been raised at the draft stage may be waived if not raised until after completion of the final environmental impact statement. Comments on the draft environmental impact statement should be specific and should address the adequacy of the statement and the merits of the alternatives discussed (40 CFR 1503.3). The opportunity to Comment ends 45 days following publication of the notice of availability (NOA) in the Federal Register.

We discuss how critical 33 threshold changes in summer discharge can potentially tilt the Eel from a recovering salmon-supporting 34 ecosystem toward a cyanobacterially-degraded one. To maintain food webs and habitats that support 35 salmonids and suppress harmful cyanobacteria, summer discharge must be sufficient to connect mainstem 36 pools hydrologically with gently moving, cool base flow. Rearing salmon and steelhead can survive even 37 in pools that become isolated during summer low flows if hyporheic exchange is sufficient.

  • An Estimation of Potential Salmonid Habitat Capacity in the Upper Mainstem Eel River, California
    AN ESTIMATION OF POTENTIAL SALMONID HABITAT CAPACITY IN THE UPPER MAINSTEM EEL RIVER, CALIFORNIA By Emily Jeanne Cooper A Thesis Presented to The Faculty of Humboldt State University In Partial Fulfillment of the Requirements for the Degree Master of Science in Natural Resources: Environmental and Natural Resource Science Committee Membership Dr. Alison O’Dowd, Committee Chair Dr. James Graham, Committee Member Dr. Darren Ward, Committee Member Dr. Alison O’Dowd, Graduate Coordinator May 2017 ABSTRACT AN ESTIMATION OF POTENTIAL SALMONID HABITAT CAPACITY IN THE UPPER MAINSTEM EEL RIVER, CALIFORNIA Emily Jeanne Cooper In Northern California’s Eel River watershed, the two dams that make up the Potter Valley Project (PVP) restrict the distribution and production of anadromous salmonids, and current populations of Chinook Salmon (Oncorhynchus tshawytscha) and steelhead trout (O. mykiss) in the upper mainstem Eel River are in need of recovery. In anticipation of the upcoming FERC relicensing of the PVP, this project provides an estimation of the extent of potential salmonid habitat and its capacity for steelhead trout and Chinook Salmon in the upper mainstem Eel River watershed above the impassable Scott Dam. Using three fish passage scenarios, potential Chinook Salmon habitat was estimated between 89-127 km (55-79 mi) for spawning and rearing; potential steelhead trout habitat was estimated between 318-463 km (198-288 mi) for spawning and between 179-291 km (111-181 mi) for rearing. Rearing habitat capacity was modeled with the Unit Characteristic Method, which used surrogate fish density values specific to habitat units (i.e. pools, riffles, runs) that were adjusted by measured habitat conditions.

  • Salmonid Habitat and Population Capacity Estimates for Steelhead Trout and Chinook Salmon Upstream of Scott Dam in the Eel River, California
    Emily J. Cooper1, Alison P. O’Dowd, and James J. Graham, Humboldt State University, 1 Harpst Street, Arcata, California 95521 Darren W. Mierau, California Trout, 615 11th Street, Arcata, California 95521 William J. Trush, Humboldt State University, 1 Harpst Street, Arcata, California 95521 and Ross Taylor, Ross Taylor and Associates, 1660 Central Avenue # B, McKinleyville, California 95519 Salmonid Habitat and Population Capacity Estimates for Steelhead Trout and Chinook Salmon Upstream of Scott Dam in the Eel River, California Abstract Estimating salmonid habitat capacity upstream of a barrier can inform priorities for fisheries conservation. Scott Dam in California’s Eel River is an impassable barrier for anadromous salmonids. With Federal dam relicensing underway, we demonstrated recolonization potential for upper Eel River salmonid populations by estimating the potential distribution (stream-km) and habitat capacity (numbers of parr and adults) for winter steelhead trout (Oncorhynchus mykiss) and fall Chinook salmon (O. tshawytscha) upstream of Scott Dam. Removal of Scott Dam would support salmonid recovery by increasing salmonid habitat stream-kms from 2 to 465 stream-km for steelhead trout and 920 to 1,071 stream-km for Chinook salmon in the upper mainstem Eel River population boundaries, whose downstream extents begin near Scott Dam and the confluence of South Fork Eel River, respectively. Upstream of Scott Dam, estimated steelhead trout habitat included up to 463 stream-kms for spawning and 291 stream-kms for summer rearing; estimated Chinook salmon habitat included up to 151 stream-kms for both spawning and rearing. The number of returning adult estimates based on historical count data (1938 to 1975) from the South Fork Eel River produced wide ranges for steelhead trout (3,241 to 26,391) and Chinook salmon (1,057 to 10,117).

  • Appendix L Wild and Scenic River Evaluation
    APPENDIX L WILD AND SCENIC RIVER EVALUATION INTRODUCTION Congress passed the Wild and Scenic Rivers Act in 1968 to preserve riverine systems that contain certain exceptionally outstanding features such as scenery, recreation, geology, fish and wildlife, historic and cultural resources. Selected rivers and their immediate environments are to be preserved in a free flowing condition and are to be managed for the benefit and enjoyment of present and future generations. In October 1979, an Environmental Message from the President directed the Department of the Interior (USDI) to inventory all potential Wild and Scenic rivers and directed agencies to assess the suitability of the inventoried rivers for additions to the National Wild and Scenic Rivers System. The Nationwide Rivers Inventory (NRI) was conducted by the Heritage, Conservation and Recreation Service, USDI (now the National Park Service). The Middle Fork of the Eel River, which originates on the Mendocino National Forest, was the only river on the Mendocino National Forest included on the preliminary (Phase I) NRI in 1980. In January 1981, the Secretary of the Interior designated five California rivers as components of the National Wild and Scenic Rivers System under Section 2 (a) (il) of the National Wild and Scenic Rivers Act. The lower 23.5 miles of the Middle Fork of the Eel River was included in this designation and is currently managed as a Wild River. The upper 14.5 miles, which includes the headwaters of the Middle Fork of the Eel River, had not been analyzed for designation. This upper segment lies within the Yolla Bolly-Middle Eel Wilderness.

    Friends of the Eel River Blockwater Investigation Final Memo August 5, 2016 Prepared by: Alison O’Dowd & William Trush, Humboldt State University River Institute FOER Blockwater Investigation Final Memo August 5, 2016 Prepared by: Alison O’Dowd and William Trush Humboldt State University River Institute SUMMARY There is currently no quantitative method to guide the 2,500 ac-ft annual blockwater release from the Potter Valley Project into the Mainstem Eel River. The four blockwater releases between WY2012-WY2016 used a variety of strategies in attempts to assist outmigrating juvenile salmonids. This study compared impaired (with dams) and modeled unimpaired flow conditions in the Mainstem Eel River downstream of Cape Horn Dam to see how the flows could be managed to optimize juvenile salmonid habitat during the spring hydrograph recession limb. Annual hydrographs of measured impaired flows exhibited steeper spring recession limbs and lower flows earlier in the summer compared with modeled unimpaired annual flows. The unimpaired hydrograph may impact spring rearing habitat for salmonids (particularly Chinook salmon) in terms of fish mobility, habitat availability and quality, and riffle productivity (as related to invertebrates food resources). Analyses of riffle crest thalweg depths in the Mainstem Eel River over the spring and summer seasons showed that flows in the impaired hydrograph reached critical life history thresholds earlier in the season compared to the modeled unimpaired flows. We recommend the following: 1) for dam releases
