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. -
Bryophyte Surveys 2009
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. -

2.10 Meesia longiseta HEDW. Code: 1389 Anhang: II KLAUS WEDDELING, GERHARD LUDWIG & MONIKA HACHTEL, Bonn Namen: D: Langstieliges Schwanenhalsmoos, Langstieliges Meesemoos, Gestreckte Langborste E: Long-stalked Thread Moss, Long-shafted Swan Moss, F: – Systematik/Taxonomie: Bryophyta, Bryopsida, Bryidae, Splachnales, Meesiaceae. Synonyme: Amblyodon longisetus (HEDW.) P. BEAUV. Kennzeichen/Artbestimmung: Meesia longiseta ist ein 4–8 (–10) cm hohes, akrokarpes, unverzweigtes Laubmoos von grün-schwärzlicher Färbung. Die Art wächst in lockeren, weichen Rasen (Abb. 2.9). Das Stämmchen ist bis in die Spitze wurzelhaarig und im Moose Querschnitt dreikantig. Die Blättchen sind mehr oder weniger deutlich in 3 oder 6 Rei- hen angeordnet und vom Stämmchen abgespreizt. Die 2–3,5 mm langen, spitzen Blätt- chen laufen deutlich am Stämmchen herab, sind oberwärts gekielt, ganzrandig oder an der Spitze etwas gezähnt. Ihre deutlich entwickelte Rippe endet unterhalb der Blattspitze. Der Blattrand ist flach. Die Laminazellen sind rechteckig bis rhombisch und etwa 14 µm breit. Die rötlichen, gedrehten Seten der synözischen Art können über 10 cm lang wer- den. Die langbirnenförmige, aufrechte Kapsel hat einen deutlichen Hals. Bei der Spo- renreife im Juni und Juli werden die mit 36–44 µm Durchmesser recht großen Sporen frei- gesetzt. Die Chromosomenzahl ist nicht bekannt (FRITSCH 1991). Differenzierende Merkmale zu den ähnlichen Arten Meesia uliginosa und M. hexasticha sind der nicht ein- gerollte Blattrand, die kleineren Sporen und der Rippenquerschnitt mit kleinen, inneren Zellen (zusammengestellt nach CRUM & ANDERSON 1981, FRAHM 1979, LIMPRICHT 1895).

Molecular Phylogeny of Chinese Thuidiaceae with Emphasis on Thuidium and Pelekium
Molecular Phylogeny of Chinese Thuidiaceae with emphasis on Thuidium and Pelekium QI-YING, CAI1, 2, BI-CAI, GUAN2, GANG, GE2, YAN-MING, FANG 1 1 College of Biology and the Environment, Nanjing Forestry University, Nanjing 210037, China. 2 College of Life Science, Nanchang University, 330031 Nanchang, China. E-mail: [email protected] Abstract We present molecular phylogenetic investigation of Thuidiaceae, especially on Thudium and Pelekium. Three chloroplast sequences (trnL-F, rps4, and atpB-rbcL) and one nuclear sequence (ITS) were analyzed. Data partitions were analyzed separately and in combination by employing MP (maximum parsimony) and Bayesian methods. The influence of data conflict in combined analyses was further explored by two methods: the incongruence length difference (ILD) test and the partition addition bootstrap alteration approach (PABA). Based on the results, ITS 1& 2 had crucial effect in phylogenetic reconstruction in this study, and more chloroplast sequences should be combinated into the analyses since their stability for reconstructing within genus of pleurocarpous mosses. We supported that Helodiaceae including Actinothuidium, Bryochenea, and Helodium still attributed to Thuidiaceae, and the monophyletic Thuidiaceae s. lat. should also include several genera (or species) from Leskeaceae such as Haplocladium and Leskea. In the Thuidiaceae, Thuidium and Pelekium were resolved as two monophyletic groups separately. The results from molecular phylogeny were supported by the crucial morphological characters in Thuidiaceae s. lat., Thuidium and Pelekium. Key words: Thuidiaceae, Thuidium, Pelekium, molecular phylogeny, cpDNA, ITS, PABA approach Introduction Pleurocarpous mosses consist of around 5000 species that are defined by the presence of lateral perichaetia along the gametophyte stems. Monophyletic pleurocarpous mosses were resolved as three orders: Ptychomniales, Hypnales, and Hookeriales (Shaw et al. -

Rare Species Survey of Uninventoried Alpine/Subalpine and Wetland Habitats Within the Oregon Cascades Recreation Area and Thielsen Wilderness Area
Rare Species Survey of Uninventoried Alpine/Subalpine and Wetland Habitats within the Oregon Cascades Recreation Area and Thielsen Wilderness Area Report to the Interagency Sensitive and Special Status Program Richard Helliwell and Daniel Thomas Umpqua National Forest Roseburg, Oregon 28 November 2012 Introduction The Mt. Thielsen Wilderness Area and Oregon Cascades Recreation Area (OCRA) occupy the High Cascades crest north of Crater Lake National Park. This area has received little botanical exploration. In fact, other than the Pacific Crest Trail and the popular trail to the peak of Mt. Thielsen, the area gets relatively little use at all. At 2799 m (9182 ft.), Mt. Thielsen is the highest peak in the vicinity. This area was surveyed in 2005 as part of a separate Interagency Sensitive and Special Status Program funded survey (Helliwell, York and Baxter 2005). This previous inventory established that the reports of Arabis suffrutescens var. horizontalis and Carex atrosquama were misidentifications however a disjunct occurrence of rare C. nardina was discovered below the summit. Tipsoo Peak (2450 m, 8034 ft.) is the only other peak in the Wilderness that has a trail to it. This peak was informally surveyed on 9 July 2000. Tanya Harvey also produced a species list for Tipsoo Peak on 13 Aug. 2006. Otherwise, there are vascular plant collections at the Oregon State University Herbarium (OSC) from the Howlock Mountain area by Wayne Rolle from 1991 and V.L. Crosby from 1975. Based on the current Umpqua National Forest sensitive species list and habitats, the following target species were identified for survey: Anastrophyllum minutum, Anomobryum julaceum, Arabis suffrutescens var. -

Inventory of Rare Bryophytes in Unique Wetland Ecosystems on the Rogue River-Siskiyou National Forest
Inventory of Rare Bryophytes in Unique Wetland Ecosystems on the Rogue River-Siskiyou National Forest Photo: L. Wilson 2010 U.S.D.A Forest Service Region 6 and U.S.D.I Bureau of Land Management Interagency Special Status and Sensitive Species Program Authors Clint Emerson is a botanist, USDA Forest Service, Rogue River Siskiyou National Forest, Gold Beach and Powers Ranger Districts, Gold Beach, OR 97465 Scot Loring is a botanist, Pacific Crest Consulting, LLC, Talent, OR 97540 Introduction The Rogue River-Siskiyou National Forest (RRSNF) dissects a geographically diverse area of Oregon, creating a high level of endemism with regard to vascular plants. At this point much less is known about non-vascular plant diversity in the region so botanists on the forest proposed a project to inventory unique wetland ecosystems for Region 6 Sensitive, Strategic and Oregon Biologic Information Center (ORBIC) list 3 and 4 bryophytes (mosses, liverworts and hornworts). The project received funding from the Interagency Special Status and Sensitive Species Program (ISSSSP) for field work to begin during the 2009 field season. This report summarizes findings of the inventory. Wetland ecosystems are an uncommon feature of the steep and highly dissected Siskiyou Mountains in Southwest Oregon. They are dispersed more so within the Southern Oregon Cascade portion of the forest, but are still considered an uncommon feature on the landscape when compared to unique upland ecosystems such as prairies or rock outcrops. In comparison to northwestern Oregon and western Washington little information exists with regard to Sensitive wetland associated bryophytes in southwest Oregon. This may be due to the fact that large metropolitan areas with universities are mostly lacking from the region and therefore the expertise and funding to accomplish this type of work is not as available. -
