Ojai Ave, Ojai, CA 93023 (805) 646-4348 ext. 316 Abstract The Los Padres National Forest (LPNF) proposes to control the invasive species tamarisk in portions of the Piru Creek, Lockwood Creek, Cuyama River, Santa Ynez River, Sespe Creek, Sisquoc River, and Arroyo Seco River watersheds. This action will result in the improvement of riparian ecosystems that have been impacted by the invasion of tamarisk. Tamarisk has replaced the native riparian plant community of willows, cottonwoods and other desirable native riparian species. The water-consuming ability of tamarisk has reduced the surface water available to wildlife. The best management strategy is to enact control measures now before the tamarisk infestations become larger. It is important that reviewers provide their comments at such times and in such a way that they are useful to the Agency’s preparation of the EIS. Therefore, comments should be provided prior to the close of the comment period and should clearly articulate the reviewer’s concerns and contentions. The submission of timely and specific comments can affect a reviewer’s ability to participate in subsequent administrative review or judicial review. Comments received in response to this solicitation, including names and addresses of those who comment, is part of the public record for this proposed action. Comments submitted anonymously will be accepted and considered; however, anonymous comments will not provide the respondent with standing to participate in subsequent administrative or judicial reviews. Send Comments to: Lloyd Simpson Los Padres National Forest 1190 E. Ojai Ave, Ojai, CA 93023 Date Comments Must Be Received: Within 45-days from the date the Notice of Availability (NOA) is published in the Federal Register. If the NOA is published June 10, 2016, then comments are due on July 25, 2016. i Draft Environmental Impact Statement - Los Padres National Forest Tamarisk Removal Project Summary The Los Padres National Forest is proposing to control tamarisk (Tamarix sp.) in portions of Piru Creek, Lockwood Creek, Cuyama River, Santa Ynez River, Sisquoc River, Sespe Creek, and Arroyo Seco River watersheds. The project is designed to eradicate current tamarisk infestations and to prevent its further spread. The project area is located along riparian zones of the above-mentioned waterways and proposes to treat approximately 368 linear miles along perennial and intermittent streams for an area of about 4,247 acres. Currently the infestations are composed of scattered tamarisk within riparian habitat conservation areas, congressionally designated Wilderness areas, and Wild and Scenic Rivers. The proposed project is located on all five Ranger Districts of the Los Padres National Forest. Treatments would occur only along identified reaches where it is present. Tamarisk is a nonnative invasive tree-shrub that can grow in dense patches, out-compete native vegetation such as willows (Salix sp.) and cottonwoods (Populus sp.), change soil chemistry by depositing salts from deep ground water on the soil surface, and remove large amounts of water from streams and riparian areas via evapotranspiration through its foliage. The action will result in the improvement of riparian ecosystems that have been impacted by tamarisk invasion. By removing tamarisk before it becomes the dominant vegetation component, native plant communities would be maintained, and in turn will provide a benefit to aquatic resources dependent on healthy, properly functioning riparian areas. Treatments would begin in 2016, and intensive treatment are expected to occur through 2021. Monitoring and maintenance treatments would continue thereafter to retreat existing infestations, and to treat new infestations discovered within the project area. It is anticipated that most of the project would be implemented over the next 10 years, with the most intensive treatments occurring during the first five years. No major issues were raised during scoping beyond analysis already planned for multiple resources by the interdisciplinary team. The proposed action developed by the agency includes hand pulling of tamarisk with hand application of an herbicide. The agency also developed alternatives to the proposed action including a no-action alternative, and a second action alternatives that includes hand pulling only. Major conclusions include: . The no action alternative would allow tamarisk to continue to spread . The hand pulling only alternative would not eradicate the mature tamarisk that are responsible for spreading seed and spreading tamarisk further in the watersheds Based upon the effects of the alternatives, the responsible official will decide whether or not to implement this project, either of the action alternatives, or modify the project based on public input and interdisciplinary analysis. ii Draft Environmental Impact Statement - Los Padres National Forest Tamarisk Removal Project Table of Contents Summary ......................................................................................................................................... ii Chapter 1.

  • Silversword Lineage: Revisiting Clausen, Keck, and Hiesey’S Findings1
    CONTRASTING PATTERNS AND Bruce G. Baldwin2 PROCESSES OF EVOLUTIONARY CHANGE IN THE TARWEED– SILVERSWORD LINEAGE: REVISITING CLAUSEN, KECK, AND HIESEY’S FINDINGS1 ABSTRACT Jens C. Clausen, David D. Keck, and William M. Hiesey’s biosystematic research on continental tarweeds (Madiinae; Compositae) provided diverse examples of evolutionary change for Clausen’s synthesis, Stages in the Evolution of Plant Species. Subsequent anatomical work by Sherwin Carlquist demonstrated that the tarweed lineage also includes a spectacular example of adaptive radiation, the Hawaiian silversword alliance. Molecular phylogenetic data and evidence from genetic and hybridization studies have allowed additional perspectives on Clausen et al.’s and Carlquist’s hypotheses of tarweed– silversword evolution. In Californian Layia, Clausen et al.’s evidence for gradual allopatric diversification for the n 5 7 taxa accords with patterns of molecular divergence and decay of interfertility across lineages inferred from a rate-constant rDNA tree. In contrast, recent evidence on patterns and timing of diversification in an n 5 8 Layia clade indicates multiple examples of accelerated phenotypic evolution, unresolved by Clausen et al., that evidently reflect rapid "budding off" of morphologically distinct lineages in ecologically novel settings. In rDNA trees of Californian Holocarpha, lineages representing different cryptic biological species, documented by Clausen, appear to predate the origin of a morphologically and ecologically distinctive taxon (H. macradenia (DC.) Greene) that retains interfertility with relatives of ancestral phenotype; at fine-scale levels of divergence, a disconnect is evident between evolution of intrinsic, post-mating reproductive barriers and phenotypic evolution in Holocarpha. Clausen’s evidence for strong intersterility barriers between the mostly annual, continental species of the ‘‘Madia’’ lineage contrasts with Gerald D.

As part of that examination, Irvin Fox-Fernandez and I surveyed the area of the boundary change and several of the roads on March 23,2010. No occurrences of sensitive plant species were detected in the suitable range of the boundary extension for the Rodeo Flat Unit. This is a relatively small area of 56 acres of secondary suitable range and 5 acres of primary suitable range. This extension will have no effect on the Sensitive Plant species discussed in the plant Biological Evaluations. During our surveys of the roads on March 23, 2010 and October 11,2007, we examined likely habitat along the roads and found no occurrences of Sensitive Plants species. Since maintenance will occur on the existing road bed or trail footprint only, it is not likely that there will be any direct effect on sensitive plants. Since there were no sensitive plants found in the areas adjacent to the roads and trails, it is unlikely that any indirect effects will occur either.
