A total of 44 plans were surveyed to completion; two plans were initiated in 2017 and completed in 2019; two plans were initiated in 2018 and were completed in 2019; and seven plans were initiated in 2019 and will be completed in 2020. The 2019 floristic survey season commenced on March 4th and terminated on August 30th with an estimated 130 field days. A total of 164 new California Rare Plant Rank (CRPR) 1-2 BotID#s were generated representing 10 taxa. It is worth noting that 77 of the 164 new CRPR 1-2 BotID#s are previously unrecorded populations of Monotropa uniflora. A total of 123 new CRPR 3-4 BotID#s representing 15 taxa were generated as part of a continued commitment to collecting spatial and habitat data for uncommon species. There were no State or Federally listed Rare, Threatened or Endangered species observed during the 2019 survey effort. Within the Coastal Lagoons and Little River Botanical Management Area (CL/LR BMA), five harvest plans were reviewed and three received surveys in unique habitats. Running pine (Lycopodium clavatum) was the most prevalent uncommon plant encountered in the harvest plans. Per GDRCo’s Master Agreement for Timber Operations (MATO), the botany crew surveyed 28 road points associated with the Annual Work Plan. This plan describes planned road

Factors found to favor seedling establishment were abundance of sound seed, mineral soil seedbed, and probably some shade in the first year. Chief obstacles to seedling survival and growth included strong insolation, deep litter, insects, competing low vegetation, and time between good seed years. The most practical approach to securing natural regeneration appears to be keeping abundant seed trees close to a prepared mineral soil seedbed.

DATE: November 2009 APPROVED BY: DATE: _____________ Name, Forest Botanist, Lake Tahoe Basin Management Unit SUMMARY OF EFFECTS DETERMINATION AND MANAGEMENT RECOMMENDATIONS AND/OR REQUIREMENTS One population of a special-status bryophyte, three-ranked hump-moss (Meesia triquetra), was observed in the survey area during surveys on June 30, 2008 and August 28, 2008. The proposed action will not affect the moss because the population is located outside the project area where no action is planned. The following species of invasive or noxious weeds were identified during surveys of the Project area: cheatgrass (Bromus tectorum); bullthistle (Cirsium vulgare); Klamathweed (Hypericum perforatum); oxe-eye daisy (Leucanthemum vulgare); and common mullein (Verbascum Thapsus). The threat posed by these weed populations would not increase if the proposed action is implemented. An inventory and assessment of invasive and noxious weeds in the survey area is presented in the Noxious Weed Risk Assessment for the Upper Truckee River Sunset Stables Restoration Project (ENTRIX 2009). Based on the description of the proposed action and the evaluation contained herein, we have determined the following: There would be no significant effect to plant species listed as threatened, endangered, proposed for listing, or candidates under the Endangered Species Act of 1973, as amended (ESA), administered by the U.S.

  • Fire-Resistant Plants for Oregon Home Landscapes
    FFire-ire-RResistantesistant PlantsPlants forfor OregonOregon HomeHome LandscapesLandscapes Suggesting specific types of vegetation that may reduce your risk from wildfire. Stephen Fitzgerald Area Extension Forester and Associate Professor Amy Jo Waldo Area Extension Horticulture Agent and Assistant Professor OSU Extension Service 1421 S. Hwy 97, Redmond, OR 97756 Introduction Oregon has many wildfire prone areas. In these places, fires are a natural part of the changing landscape. As homes are built in these areas, special precautions must be taken by the homeowner to pro- tect their property. Installation of fire- resistive roofing is critical to preventing firebrands from igniting the home from a roof fire. Well maintained fire-resistant vegetation and irrigated landscape is also critical within close proximity of a home. These actions DO NOT insure that your home will survive a wildfire, but they provide for a good chance of structural survival. Implementation of FireFree [www.firefree.org] and FireWise [www.firewise.org] activities can also significantly improve chances of a home surviving a wildfire. Fire-resistant vegetation. When landscaping around a home, most homeowners are interested in creating a landscape that is aesthetically pleasing, compliments their home, and has varia- tions in color, texture, flowers, and foliage. If your home is located in or adjacent to forests or rangeland, you should also consider the flammability of plants within your home landscape. Flammable plant material in your land- scape can increase the fire-risk around your home. The 1991 Oakland Hills Fire in California is a prime example of how flam- mable plant material (Eucalyptus trees) can act as fuel and contribute to the inten- sity of a wildfire.

Department nf Botany The University of British Columbia 2075 Wesbrook Place Vancouver, Canada V6T 1W5 26 March 1980 ABSTRACT Seven species are recognized in Arnica subgenus Austromontana and two species in a new subgenus Calarnica based on a critical review and conserva• tive revision of the species. Chromosome numbers are given for 91 populations representing all species, including the first reports for Arnica nevadensis. Results of apomixis, vegetative reproduction, breeding studies, and artifi• cial hybridizations are given. Interrelationships of insect pollinators, leaf miners, achene feeders, and floret feeders are presented. Arnica cordifolia, the ancestral species consists largely of tetraploid populations, which are either autonomous or pseudogamous apomicts, and to a lesser degree diploid, triploid, pentaploid, and hexaploid populations.
