United States Forest Bend/Ft United States Forest Bend/Ft. Rock 63095 Deschutes Market Road Department of Service Ranger District Bend, OR 97701 Agriculture File Code: 2670 Date: 06 October 2016 Subject: Biological Evaluation –Threatened, Endangered, and Sensitive Plants Lex project To: The Record This is a biological evaluation to document consideration of Threatened, Endangered, and Sensitive (TES) plants related to the Lex project. It is prepared in compliance with the Forest Service Manual (FSM) 2672.4 and the Endangered Species Act of 1973 (Subpart B; 402.12, section 7 consultation). Effects of this activity are evaluated for those TES plant species on the current Regional Forester’s Sensitive Species List (FSM 2670.44, July 2015) that are documented or suspected to occur on the Deschutes National Forest. Finding: The alternatives are not likely to impact any Threatened, Endangered, or Sensitive species. ________________________________________________________________________________ Project Description Alternative 1 - “No Action” This alternative provides a basis for comparison to evaluate changes in the existing condition associated with the action alternatives. Under the No Action alternative, current management plans would continue to guide management of the project area. No commercial or non- commercial activities would be implemented to accomplish the project purposes. No surface or ladder fuels reduction activities would be implemented to accomplish project purposes. Alternative 2 - Proposed action Commercial harvest would include commercial and small-tree thinning of ponderosa pine and lodgepole pine and salvage of dead lodgepole pine. Management of White fir stocking levels would be limited to young stands, and in circumstances where it is removed to create openings to regenerate ponderosa pine that historically existed on the landscape. Commercial thinning could include products such as commercial firewood sales, post and Lex Biological Evaluation – Plants Page 1 of 24 pole sales, and traditional saw log material. Harvest would be conducted with mechanical surface logging methods to reduce tree stocking, control species composition and reduce the accumulation of dead, down woody material. Opportunities for small tree harvest could include biomass or personal use firewood, or both. Small tree treatments would be conducted by cutting with chainsaws, mechanical removal similar to logging, or mastication. This would be used to reduce tree stocking, control species composition and reduce ladder fuels. Slash would either be lopped and scattered, if the additional fuel loading didn’t exceed LRMP requirements, or piled and burned. Shrub mowing or mastication would be conducted using machinery with cutting or masticating heads to reduce brush height and density, and lower the height of surface fuels from other activities or which have naturally accumulated. Underburning would be conducted in stands in conjunction with other treatments to consume surface fuels, and reinitiate natural processes. Piling and burning of slash would occur in areas where underburning is not proposed and the amount of slash is determined to be a high risk to carry fire at high intensities. Tree planting would occur in areas that are below minimum stocking requirements. Gopher trapping and herbicide treatment will be used to ensure planting is successful. Alternatives 3-4 Both alternatives 3 and 4 include overstory and understory treatments using various methods to create healthy and resilient stands. Alternative 3 proposes more acres of overstory treatment while alternative 4 proposes less acres of overstory and understory treatments. Both alternatives include 866 acres of prescribed burning along with Herbicide use to reduce competing vegetation around trees that will be planted (about 100 acres). Further alternative analysis and comparisons are detailed in the EA Chapter 2. The following table is a breakdown of treatment acreas for each alternative.

The elevation varies between 5200-6000’. The average annual precipitation measures about 30”. The project boundary is entirely within the Northwest Forest Plan. Two documented Sensitive plant sites are located within the boundary, both are small Castilleja chlorotica populations, which were unable to be relocated when checked. Field Reconnaissance Field checks were conducted on 6/19/2014 by Charmane Powers, Bend/Ft. Rock District Botanist, for the two documented Castilleja chlorotica or green-tinged paintbrush sites. Site #0100230 in unit 041 originally only had three plants documented in 2007; none were found in 2014. Site #0100222, outside of any proposed units, had four plants in 1995 and none in 2014. Both sites were not found in what is considered typical Castilleja chlorotica habitat. The surrounding areas were checked but no further surveys were deemed necessary due to the lack of good quality habitat for green-tinged paintbrush. Surveys were conducted in 2013 and 2014 for Survey and Manage fungi species. The areas targeted for surveys were in mixed conifer old growth patches most likely to contain Survey and Manage species, and potentially listed TES fungi. Deschutes Botanist, Rick Dewey, conducted surveys in both spring and fall during the two years and found no species on either list. Other TES surveys were conducted within the project area in previous years. KIT, Wanago add-on, and the Kapka project surveys did not locate any TES. Castilleja chlorotica Lex Biological Evaluation – Plants Page 4 of 24 Lex Biological Evaluation – Plants Page 5 of 24 Project Effects and Finding Alternative 1 – No Action Direct and Indirect Effects The only known TES plant species are the two documented Castilleja chlorotica populations that were no longer present in the current stand conditions. It is probable that they were affected by sucession and overstory competition. Through management of the overstory there is potential for the populations to reestablish in the more suitable habitat. If this is the case, then the no action alternative would provide no benefit to Castilleja chlorotica. Alternatives 2, 3, and 4 Direct Effects – Castilleja chlorotica habitat Although no C. chlorotica was located in recent surveys, it is possible that through stand and fuels management, habitat for C. chlorotica would be enhanced such that it would regenerate at the locations it was previously found, and potentially at other sites. The historic site located in unit 41will not be impacted by any planting or herbicide treatments as those activities are not proposed for the unit. However, seed tree final removal and precommercial thinning activities are proposed causing ground disturbance to the once active C. chlorotica site. Because no plants have been found, there is no direct effect to a population and the activities may only enhance its habitat as previously mentioned. Cumulative Effects – Both alternatives There are no anticipated cumulative effects to TES plants within the project because none were found. Deschutes National Forest Land and Resource Management Plan (LRMP) Consistency The Lex project as regards TES plant species is consistent with the Deschutes LRMP (1990). Records were checked for previously known TES plant populations (TE-1), and low quality habitat was located for the green-tinged paintbrush (TE-2). Targeted surveys were conducted at the locations of historic green-tinged paintbrush populations (TE-3). The remaining standards and guidelines for TES plant species do not apply to the Lex project. Lex Biological Evaluation – Plants Page 6 of 24 Finding: The alternatives would have no impact on Threatened, Endangered, or Sensitive plant species.

  • "National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."
    Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment.

VITT1 & MELISSA HOUSE1 1School of Biological Sciences, Southern Illinois University, Carbondale, IL, 62901, U.S.A., �[email protected]; https://orcid.org/0000-0002-7808-3964 �[email protected]; https://orcid.org/0000-0002-7635-9541 Abstract Bryophytes play a number of important roles in the functioning and structure of northern peatlands where they form the ground layer of fens and bogs. Sphagnum, dominant in bogs and poor fens, and brown mosses, dominant in rich fens, make up a large percentage of the organic matter that is stored as deep deposits of peat. In this paper we review the mechanisms of resistance to decay in these two moss groups. We then document a case study of a rich fen dominated mostly by Hamatocaulis vernicosus, that has remained stable for over 8000 calendar years. At this site, we use macrofossil abundances, including bryophyte habitat positions on water level and chemistry gradients, to infer past environmental conditions. Lastly, we provide a new ecohydrologic framework for wetland classes centered on bryophyte abundances across water level, nutrient, and salinity gradients and argue that bryophyte species are among the most significant indicators for classifying wetland site-types. Key words: Bog, bryophyte, community stability, ecohydrology, fen, Hamatocaulis vernicosus, moss, peatland classification Introduction Bryophytes are small plants that are abundant and dominate in only a few terrestrial ecosystems.

  • Vegetative Ecology of a Montane Mire, Crater Lake National
    AJ ABSTRACT OF THE THESIS OF Susan Cornelia Seyer for the degree of Master of Science in Botany and Plant Pathology presented on December 14, 1979 Title: VEGETATIVE ECOLOGY OF A MONTANE MIRE, CRATER LAKE NATIONAL PARK, OREGON Redacted for Privacy Abstract approved: Jerry F. Franklin Mires, or peat-producing ecosystems, dominated by sedges, shrubs, and brown mosses, are common features in Cascade subalpine regions, occurring where moisture accumulates in small basins or on poorly-drained slopes. Although descriptions and classifications have been developed for mire vegetation in much of the world, there is little information of even a descriptive nature for these montane mires in Oregon and Washington. This thesis reports on phytosocia- logical structure, env'ironental relations, and successional trends in one such mire in the Oregon Cascade mountains. To characterize the general phytosociological structure of the mire vegetation at Sphagnum Bog, Crater Lake National Park, quantitative species cover data were used in conjunction with a Braun-Blanquet tabular analysis and two-dimensional stand ordinations, reciprocal averaging and a Bray-Curtis polar ordination. Defined community types correspond to physiognomic types as follows: Carex rostrata (reedswamp); Eleocharis pauciflora-Carex limosa, Eleocharis pauciflora/bryophytes (low sedge fens); Carex sichensis (tall sedge fen); Vaccinium/ Aulacomnium palustre, Vaccinium occidentala/Carex sitchensis (shrub thickets; Alnus incana/Brachythacium sp. and Salix barclayi (marginal carrs).Phases were defined when appropriate. A vegetation map was made to illustrate the locations and extent of the variouscommunities. Comparisons with other montane mires in thearea determined that the physiognomic units defined are repeatable when appropriate habitat conditions are present, and that they usually includemany of the same characteristic species, the dominant mosses being particularly constant.

The type of habitat was also determined to clarify whether the habitat is a wet or dry meadow, bog or fen. Bryophyte identification was begun in 2010 with the first specimens collected and continued on through 2011 when most priority bryophytes were identified. The meadows selected represent the highest probability habitat for wetland bryophytes and fungi on Detroit and Sweet Home Ranger Districts. Some of these meadows may have been surveyed for vascular plant species in the past, but there are many new non-vascular sensitive species on the Willamette NF 2008 sensitive species list (see attachment 1) and additional species being being added to the proposed 2012 Regional Forester’s sensitive species list (unpublished). Meadows surveyed on the Detroit Ranger District included: Tule Lake meadow complex, Twin Meadows, Marion Lake meadow complex, Jo Jo Lake site, Wild Cheat Meadows, Bruno Meadows, Pigeon Prairie Meadow complex and Big Meadows. On the Sweet Home Ranger District Gordon Lake Meadows Complex was surveyed.

  • (Warnstorfia Fluitans (Hedw.) Loeske) from a High Arctic Lake: Effect of Nutrient Concentration Tenna Riis,1,2 Birgit Olesen,1 Casper K
    ARCTIC VOL. 63, NO. 1 (MARCH 2010) P. 100–106 Growth Rate of an Aquatic Bryophyte (Warnstorfia fluitans (Hedw.) Loeske) from a High Arctic Lake: Effect of Nutrient Concentration Tenna RIIS,1,2 BIrgIT OLESen,1 CASPer K. Katborg1 and KIRSten S. ChrIStoFFerSen3 (Received 12 September 2008; accepted in revised form 7 April 2009) ABSTRACT. The High Arctic is one of the regions most susceptible to climate change on a global scale. Increased temperature, precipitation, and cloud cover are anticipated in the region, with consequent increases in nutrient runoff to surface waters. Mosses are often the dominant submerged macrophyte in Arctic and High Arctic lakes. If the growth rate of mosses in these lakes is nutrient-limited, then production could increase with climate changes that result in higher nutrient concentrations. We conducted a laboratory study to 1) measure the growth response of Warnstorfia fluitans (Hedw.) Loeske from a High Arctic lake to nitrogen and phosphorus availability; and 2) determine whether growth rate was N- or P-limited by examining its relationship to internal P and N content. The growth rates of W. fluitans were generally low, ranging from 0.003 to 0.012 day-1. The growth rates increased with increasing plant P content, but not with increasing N content, indicating that moss growth was P-limited at low P availability in the experiment. Critical plant P concentration for maximum growth rate was 0.086% dry weight. This is the first time a critical P threshold has been calculated. The results imply that if climate changes result in increased P concentrations in surface waters, a higher production of moss could occur in High Arctic lakes.
