A total of 53 plans were surveyed to completion; 6 plans were initiated in 2017 and completed in 2018; and 3 plans were initiated in 2018 and will be completed in 2019. The 2018 floristic survey season commenced on March 12th and terminated on September 7th with an estimated 120 field days. A total of 152 new California Rare Plant Rank (CRPR) 1-2 BotID#s were generated representing 8 taxa. It is worth noting that 118 of the 152 new CRPR 1-2 BotID#s are previously unrecorded populations of Monotropa uniflora. A total of 177 new CRPR 3-4 BotID#s representing 13 taxa were generated as part of a continued commitment to collecting spatial and habitat data for uncommon species. No State or Federally listed Rare, Threatened or Endangered species were identified during the 2018 survey effort. Within the Coastal Lagoons and Little River Botanical Management Area (CL/LR BMA), 13 harvest plans were reviewed and 12 received surveys in unique habitats. One population of seaside bittercress (Cardamine angulata) was detected in the BMA, which added to the range extension of this species from last year. In addition, several populations of running pine (Lycopodium clavatum) and other uncommon native plants were identified including trailing black currant (Ribes laxiflorum), Pacific golden saxifrage (Chrysosplenium glechomifolium) and heart leaved twayblade (Listera cordata). A summary data set for all occurrences has been prepared and will be submitted to the California Natural Diversity Database (CNDDB). This report includes 367 field survey forms for all CRPR taxa discovered in 2018, 216 follow-up forms for 17 taxa, and the corresponding location data in ESRI File Based Geodatabase (FBGDB) format. Note that 94 of the 216 follow-ups were associated with Monotropa uniflora populations. Monitoring for Montia howellii in the Salmon Creek Tract continued for an eighth consecutive year. Surveys were conducted by a 4-person technical team from February 19th through March 12th for a total of 11 field days. Results of the occupancy data show a decreasing trend and a substantial amount of variability from year to year. Downward trending occupancy is presumed to be associated with habitat loss associated with minimization of road use in compliance with the existing Road Sediment Reduction Plan as described in the South Fork Elk River Management Plan (GDRCo 2006).

    Interagency Special Status Species Program Survey of Large Meadow Complexes for Sensitive Bryophyte and Fungal Species in the Northern Willamette National Forest Chris Wagner Willamette National Forest Detroit Ranger District District Botanist October 2011 1 Table of contents Introduction / Project Description……………………………………………………………..3 Sites Surveyed and Survey Results……………………………………………………………..4 Meadows, Information, Results…………………………………………………………………..9 Potential Future Survey Work………………………………………………………………………………14 References……………………………………………………………………………………….….…...15 ATTACHMENT 1: Regional Forester’s Special Status Species List for the Willamette National Forest (Revised 2008)……....................…………..16 2 Introduction Surveys were completed in 2010 and 2011 for large meadow complexes in the northern districts of the Willamette National Forest to determine whether any sensitive species of bryophytes or fungi are present. 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.

All occurrences were previously known from the project treatment area. Design criteria have been created for all Rogue River-Siskiyou National Forest (RRSNF) sensitive plant species within the proposed project treatment area to ensure that all occurrences would receive minimal or no negative impacts from the proposed project implementation. The five Forest Service sensitive plant species found within the footprint of the proposed project treatment area will be flagged and avoided to prevent any direct impacts to individuals. There are other FS sensitive botanical species and survey and manage species occurrences within the Sucker Creek Watershed. These occurrences, however, are not within proximity of the proposed project treatment analysis area, therefore there would be no effects and they are not considered or discussed further in this analysis.

October 2013. Special Vascular Plants, Bryophytes, and Lichens List. Quarterly publication. 73 pp. SPECIAL PLANTS Last updated July, 2013 “Special Plants” is a broad term used to refer to all the plant taxa inventoried by the Department of Fish and Wildlife’s California Natural Diversity Database (CNDDB), regardless of their legal or protection status. Special Plants include vascular plants and high priority bryophytes (mosses, liverworts, and hornworts). A few lichens are also tracked. Special Plant taxa are species, subspecies, or varieties that fall into one or more of the following categories: - Officially listed by California or the Federal Government as Endangered, Threatened, or Rare; - A candidate for state or federal listing as Endangered, Threatened, or Rare; - Taxa which meet the criteria for listing, even if not currently included on any list, as described in Section 15380 of the California Environmental Quality Act (CEQA) Guidelines; these taxa may indicate “None” under listing status, but note that all CNPS Rank 1 and 2 and some Rank 3 and 4 plants may fall under Section 15380 of CEQA. - A Bureau of Land Management, U.S. Fish and Wildlife Service, or U.S. Forest Service Sensitive Species; - Taxa listed in the California Native Plant Society’s Inventory of Rare and Endangered Plants of California; - Taxa that are biologically rare, very restricted in distribution, or declining throughout their range but not currently threatened with extirpation; - Population(s) in California that may be peripheral to the major portion of a taxon’s range but are threatened with extirpation in California; and - Taxa closely associated with a habitat that is declining in California at a significant rate (e.g.

They include one occurrence Iliamna lactibracteata (California globe-mallow), one occurrence of Pyrola dentata (toothed wintergreen), seven occurrences of Cypripedium fasciculatum (clustered lady’s-slippers) and numerous occurrences of the sensitive plant species Sophora leachiana (western sophora) within the proposed project footprint. All occurrences found during floristic surveys conducted for the proposed project or were previously known and documented. Design features have been created for all Rogue River-Siskiyou National Forest (RRSNF) sensitive plant species within the proposed Upper Briggs Restoration Project area to ensure that all occurrences do not receive negative impacts from the proposed project implementation. However, some occurrences could receive long-term benefits from the proposed project implementation. Strategic and Survey and Manage species found within the project area will be discussed in a separate specialist report.
