Auggie Creek Restoration/Fuels Project Threatened, Endangered, and Sensitive Plant Report Darlene Lavelle December 17, 2008 Auggie Creek Restoration/Fuels Project Threatened, Endangered, and Sensitive Plant Report Darlene Lavelle December 17, 2008 Introduction The Seeley Lake Ranger District, Lolo National Forest (LNF), is proposing a restoration project designed to restore forest conditions on approximately 965 acres of Forest Service lands within the Auggie, Seeley, and Mountain Creek drainages. The vegetation treatments are designed to develop a diverse mix of vegetative composition and structure, reduce the risk of bark beetle infestations, and reduce the threat of sustained high intensity wildfire in the wildland-urban interface. Commercial and noncommercial treatments are proposed to reduce stand density, ladder fuels and ground litter, and some dead and down woody debris. Reducing fuels would thereby reduce the risk from insect and disease damage and also the potential for high intensity natural fires around private homes. Fire would also allow an increase of nutrients to plants on the site. Other project proposals include: • Herbicide treatment of weeds along the approximate 12.45 miles of timber haul routes and landings and the approximate 2.37 miles of stored or decommissioned roads mentioned below; • Build about 0.59 miles of temporary road for tree harvest and then decommission these roads. • Store about 1.78 miles of road (close roads to vehicular traffic but keep roads for future use) • Plant western larch and Douglas-fir on about 44 acres within the commercial treatment units to enhance species diversity. • Replace two culverts which are fish barriers, along Swamp Creek and Trail Creek. • Implement additional best management practices (BMPs) involving road drainage at the Morrell Creek Bridge. Forest Plan and Regulatory Framework Forest Service Manual (FSM) directions 2670.11, 2670.21 and 2670.31, and the Lolo National Forest Plan standards 24 and 27, require that the LNF not only manage for endangered, threatened, and proposed species, but also recover them. The Endangered Species Act (ESA) states that all federal departments and agencies shall seek to conserve endangered and threatened species. The FSM directs the forests to manage National Forest System habitats and activities for threatened and endangered species to achieve recovery objectives so that special protection measures provided under the ESA are no longer necessary. The Lolo Forest Plan follows this direction and states all threatened and endangered species occurring on the LNF will be managed for recovery to a non-threatened status. The Forest Service Manual (FSM) and the Lolo National Forest Plan require the Lolo National Forest (LNF) to manage for sensitive species. The FSM defines sensitive species as those plants identified by the Regional Forester for which population viability is a concern, as evidenced by 1 significant current or predicted downward trends in population numbers, density or habitat capability that would reduce a species distribution (FSM 2670.5(19)). The FSM directs the forests to develop and implement management practices to ensure that sensitive species do not become threatened or endangered because of Forest Service actions (FSM 2670.22 and 2670.32). Lolo Forest Plant standard 27 also directs the forest to manage sensitive species to maintain population viability. There are no forest management areas specific to sensitive species. Species of Interest and Species of Concern The Lolo NF will be revising the Forest Plan which provides similar direction for plant species of interest and concern, as well as the Regional Forester’s sensitive plants. Some of the current sensitive species are species of interest (SOI) or species of concern (SOC). Species of interest are plants that have been assigned a state rank of S1 or S2 and a global rank of G4 or G5 by NatureServe (http://www.natureserve.org/explorer/) in association with the Montana Natural Heritage Program. The lower the number ranking, the higher the threats are to a species. Species of interest also include plants that are of interest to the Confederated Salish and Kootenai Tribe, and rare plants on the Lolo NF with limited distribution where viability is a concern. Species of concern are plants that have been assigned a global rank of G1, G2, or G3 by NatureServe. Species of concern are globally rare plants. For a complete definition of SOI and SOC plants see the Forest Service Handbook (FSH) 1901.12, 43.22Band 43.22c. Analysis Area Boundary The Auggie Creek Project area is located in Missoula and Powell Counties. The project consists mainly of two areas, the Auggie Creek treatment area (T17N, R15 W, and portions of Sections 24, 25, 26, 27, 34, and 35) and the Mountain Creek treatment area (T17N, R14W, Sect 32). The analysis area is located east of Seeley Lake and Highway 83 and north and south of Cottonwood Lakes RD 477. Analysis Methods In addition to surveying for rare plants in the analysis area (which is discussed below in the Existing Condition section of this report), a habitat suitability analysis was conducted for 52 sensitive plants, species of concern (SOC), and species of interest (SOI) to determine the potential for occurrence within the analysis area. These 52 plants are listed in Table 1. 2 Table 1.

The highest diversity of the area is within in the wetlands, edges of wetlands, and along the creeks. Over 200 species of vascular plants were identified in the Auggie Creek treatment area alone. 3 The elevation range in the analysis area is mainly 4,100 to 4,400 feet. The Mountain Creek treatment area contains wetlands and a ponderosa pine plantation. There are also stands of mixed coniferous forests in the Mountain Creek portion, containing ( Pinus ponderosa ) ponderosa pine, ( Psuedotsuga menziesii ) Douglas-fir, ( Larix occidentalis ) larch, ( Pinus contorta ) lodgepole, ( Picea engelmannii ) Engelmann spruce, ( Abies grandis ) grand fir, ( Abies lasiocarpa ) subalpine fir, and ( Populus tremuloides ) aspen. A common forest habitat type in the area is Psuedotsuga menziesii/Vaccinium spp. (Douglas-fir/huckleberry). The Auggie Creek treatment area also contains wetlands and mixed coniferous forests.

    Grizzly Bear Scientific Name: Ursus arctos Species Code: M-URAR Status: Blue-listed Distribution • Provincial Range Grizzly bears are distributed throughout most of the mainland of the province. They are absent from Vancouver Island, the Queen Charlotte Islands and outer coastal islands. They occur in all biogeoclimatic zones in the province, except the Coastal Douglas Fir zone (CDF). They utilize a wide variety of habitats ranging from coastal estuaries to alpine meadows. • Elevational Range: Sea-Level to Alpine • Provincial Context Grizzly bears are most abundant in the coastal ecosystems and in areas in the southern Rocky Mountains (Flathead area and Glacier National Park). The current population estimate for grizzly bears in British Columbia is approximately 13,000 (Fuhr and Demarchi 1990). • Range in Project Area: Ecoprovince: Southern Interior Mountains Ecoregions: Columbia Mountains and Highlands, Southern Rocky Mountain Trench, Western Continental Ranges Ecosections: Eastern Purcell Mountains, East Kootenay Trench, Southern Park Ranges Biogeoclimatic Zones: IDFdm2; MSdk; ESSFdk, ESSFdku; ESSFdkp; ESSFwm; AT Ecology and Key Habitat Requirements Habitat use by grizzly bears is influenced primarily by food availability, the presence of suitable resting, denning and mating sites, the presence of other bears and by human development. They are very adaptable and inhabit a wide variety of habitat types from coastal coniferous forests through boreal forests to alpine/subalpine meadows and alpine tundra. Grizzly bears are omnivorous and opportunistic in their feeding habits. In late spring and early summer, the bulk of their diet is green leafy material. They will also feed on insects, fruits, berries, fish, carrion and small and large mammals.

  • Populusspp. Family: Salicaceae Aspen
    Populus spp. Family: Salicaceae Aspen Aspen (the genus Populus) is composed of 35 species which contain the cottonwoods and poplars. Species in this group are native to Eurasia/north Africa [25], Central America [2] and North America [8]. All species look alike microscopically. The word populus is the classical Latin name for the poplar tree. Populus grandidentata-American aspen, aspen, bigtooth aspen, Canadian poplar, large poplar, largetooth aspen, large-toothed poplar, poplar, white poplar Populus tremuloides-American aspen, American poplar, aspen, aspen poplar, golden aspen, golden trembling aspen, leaf aspen, mountain aspen, poplar, popple, quaking asp, quaking aspen, quiver-leaf, trembling aspen, trembling poplar, Vancouver aspen, white poplar Distribution Quaking aspen ranges from Alaska through Canada and into the northeastern and western United States. In North America, it occurs as far south as central Mexico at elevations where moisture is adequate and summers are sufficiently cool. The more restricted range of bigtooth aspen includes southern Canada and the northern United States, from the Atlantic coast west to the prairie. The Tree Aspens can reproduce sexually, yielding seeds, or asexually, producing suckers (clones) from their root system. In some cases, a stand could then be composed of only one individual, genetically, and could be many years old and cover 100 acres (40 hectares) or more. Most aspen stands are a mosaic of several clones. Aspen can reach heights of 120 ft (48 m), with a diameter of 4 ft (1.6 m). Aspen trunks can be quite cylindrical, with little taper and few limbs for most of their length. They also can be very crooked or contorted, due to genetic variability.

  • Native Orchids in Southeast Alaska
    Native Orchids in Southeast Alaska Marlin Bowles & Bob Armstrong 2019 Preface Southeast Alaska's rainforests, peatlands and alpine habitats support a wide variety of plant life. The composition of this vegetation is strongly influenced by patterns of plant distribution and geographical factors. For example, the ranges of some Asian plant species extend into Southeast Alaska by way of the Aleutian Islands; other species extend northward into this region along the Pacific coast or southward from central Alaska. Included in Southeast Alaska's vegetation are at least 27 native orchid species and varieties whose collective ranges extend from Mexico north to beyond the Arctic Circle, and from North America to northern Europe and Asia. These orchids survive in a delicate ecological balance, requiring specific insect pollinators for seed production, and mycorrhizal fungi that provide nutrients essential for seedling growth and survival of adult plants. These complex relationships can lead to vulnerability to human impacts. Orchids also tend to transplant poorly and typically perish without their fungal partners. They are best left to survive as important components of biodiversity as well as resources for our enjoyment. Our goal is to provide a useful description of Southeast Alaska's native orchids for readers who share enthusiasm for the natural environment and desire to learn more about our native orchids. This book addresses each of the native orchids found in the area of Southeast Alaska extending from Yakutat and the Yukon border south to Ketchikan and the British Columbia border. For each species, we include a brief description of its distribution, habitat, size, mode of reproduction, and pollination biology.

  • Outline of Angiosperm Phylogeny
    Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report. For further information, see the references on the last page.

  • Populus Tremula
    Populus tremula Populus tremula in Europe: distribution, habitat, usage and threats G. Caudullo, D. de Rigo The Eurasian aspen (Populus tremula L.) is a fast-growing broadleaf tree that is native to the cooler temperate and boreal regions of Europe and Asia. It has an extremely wide range, as a result of which there are numerous forms and subspecies. It can tolerate a wide range of habitat conditions and typically colonises disturbed areas (for example after fire, wind-throw, etc.). It is considered to be a keystone species because of its ecological importance for other species: it has more host-specific species than any other boreal tree. The wood is mainly used for veneer and pulp for paper production as it is light and not particularly strong, although it also has use as a biomass crop because of its fast growth. A number of hybrids have been developed to maximise its vigour and growth rate. Eurasian aspen (Populus tremula L.) is a medium-size, fast-growing tree, exceptionally reaching a height of 30 m1. The Frequency trunk is long and slender, rarely up to 1 m in diameter. The light < 25% branches are rather perpendicular, giving to the crown a conic- 25% - 50% 50% - 75% pyramidal shape.

    Populus: A Premier Pioneer System for Plant Genomics 1 1 Populus: A Premier Pioneer System for Plant Genomics Stephen P. DiFazio,1,a,* Gancho T. Slavov 1,b and Chandrashekhar P. Joshi 2 ABSTRACT The genus Populus has emerged as one of the premier systems for studying multiple aspects of tree biology, combining diverse ecological characteristics, a suite of hybridization complexes in natural systems, an extensive toolbox of genetic and genomic tools, and biological characteristics that facilitate experimental manipulation. Here we review some of the salient biological characteristics that have made this genus such a popular object of study. We begin with the taxonomic status of Populus, which is now a subject of ongoing debate, though it is becoming increasingly clear that molecular phylogenies are accumulating. We also cover some of the life history traits that characterize the genus, including the pioneer habit, long-distance pollen and seed dispersal, and extensive vegetative propagation. In keeping with the focus of this book, we highlight the genetic diversity of the genus, including patterns of differentiation among populations, inbreeding, nucleotide diversity, and linkage disequilibrium for species from the major commercially- important sections of the genus. We conclude with an overview of the extent and rapid spread of global Populus culture, which is a testimony to the growing economic importance of this fascinating genus.
