    A Bibliography of Klamath Mountains Geology, California and Oregon

    U.S. DEPARTMENT OF THE INTERIOR U.S. GEOLOGICAL SURVEY A bibliography of Klamath Mountains geology, California and Oregon, listing authors from Aalto to Zucca for the years 1849 to mid-1995 Compiled by William P. Irwin Menlo Park, California Open-File Report 95-558 1995 This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards (or with the North American Stratigraphic Code). Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. PREFACE This bibliography of Klamath Mountains geology was begun, although not in a systematic or comprehensive way, when, in 1953, I was assigned the task of preparing a report on the geology and mineral resources of the drainage basins of the Trinity, Klamath, and Eel Rivers in northwestern California. During the following 40 or more years, I maintained an active interest in the Klamath Mountains region and continued to collect bibliographic references to the various reports and maps of Klamath geology that came to my attention. When I retired in 1989 and became a Geologist Emeritus with the Geological Survey, I had a large amount of bibliographic material in my files. Believing that a comprehensive bibliography of a region is a valuable research tool, I have expended substantial effort to make this bibliography of the Klamath Mountains as complete as is reasonably feasible. My aim was to include all published reports and maps that pertain primarily to the Klamath Mountains, as well as all pertinent doctoral and master's theses.

Together they comprise about 133,000 acres (540 km2), including 37 miles of coast line. Almost half of the remaining old growth redwood forests Blechnaceae – Deer Fern Family are protected in these four parks.

The area’s rich plant and animal life draws naturalists from all over the world. Outdoor enthusiasts enjoy its rugged mountains, its many lakes, its wildernesses, and its wild rivers. Geologists come here to refine the theory of plate tectonics. Yet, the Klamath Mountains are one of the least-known parts of the state. The region’s complex pattern of mountains and rivers creates a bewil- dering set of landscapes.

The book presents detailed information on the biology, habitats, and life histories of the 96 species of mammals of the Oregon coast. Soils, geology, and vegetation are described and related to wildlife habitats for the 65 terrestrial and 31 marine species. The book is not simply an identification guide to the Oregon coast mammals but is a dynamic portrayal of their habits and habitats. Life histories are based on fieldwork and available literature. An extensive bibliography is included. Personal anecdotes of the authors provide entertaining reading. The book should be of use to students, educators, land-use planners, resource managers, wildlife biologists, and naturalists.

Genetic Relationships, Morphological Divergence and Ecological Correlates in Three Species of the Viola canadensis Complex in Western North America (209 pp.) Director of Dissertation: Harvey E. Ballard, Jr. Viola flettii, Viola cuneata and Viola ocellata are sister species within the Viola canadensis complex (Violaceae). All are endemics of western North America, growing in widely divergent ecological environments. During the summers of 1998, 1999, 2001 and 2002, leaf material for DNA extraction was collected from 26 populations of the three species, including much of their range. Analysis of V. flettii DNA using intersimple sequence repeat (ISSR) markers showed a great deal of diversity with percent polymorphic loci (P) of 65% and a disjunction between northern and southern populations. Statistical analysis of collected ecological data from V. flettii indicated a microhabitat effect of greater elevation and more southernly aspect leading to lowered genetic diversity and population size, respectively.

Foreword In 1971, I joined the Pacific Northwest Forest and Range Exper- iment Station as Station Director and, among other duties, be- came chainman of the Interagency Committee on Research Natural Areas. It was a chair that I held for 4 years, and it is a - - pleasure to reflect, more than 10 years later, on the progress that has been made. Oregon and Washington already had a vigorous program of preser- vation of Natural Areas for scientific and educational purposes in 1971. In preparation at that time were several publications important to identifying and protecting Natural Areas, including a description of natural vegetation of Oregon and Washington (Franklin and Dyrness 1973), an inventory of Federal Research Natural Areas in Oregon and Washington (Franklin and others 1972),1/ and a comprehensive inventory of Natural Areas rec- ognized by the Society of American Foresters (Buckman and Quintus 1972). The Interagency Committee, with participation from The Nature Conservancy and the States of Oregon and Washington then asked, "What should a well-balanced program of Research Natural Area preservation include?" This led to the publication, "Research Natural Area Needs in the Pacific Northwest: A Contribution to Land-Use Planning" (Dyrness and others 1975).

    AN ABSTRACT OF THE THESIS OF ERIC FORSMAN for the degree of MASTER OF SCIENCE in FISHERIES AND WILDLIFE presented on October 22, 1975 Title: A PRELIMINARY INVESTIGATION OF THE SPOTTED OWL IN OREGON Abstract approved: E. Charles Meslow Between 1970 and 1974, data were collected on the distribution and biology of the spotted owl (Strix occidentalis) in Oregon. One- hundred and sixteen pairs and seven single birds were located. Spotted owls occurred throughout the mountains of western Oregon and on the east slope of the Cascade Range at least as far east as Badger Butte, Hood River County; Abbot Butte, Jefferson County; and Swan Lake Point, Klamath County. The upper elevational limits of the species increased from about 1,350 meters in northern Oregon to 1,770 meters in southern Oregon. Although spotted owls were not uncommon in some areas, evidence indicated that the population was declining as a result of habitat loss. A total of 2,647 prey items were identified from 42 pairs of owls. Prey species included 29 mammals, 20 birds, 2 reptiles, a crayfish, a terrestrial snail, and 26 genera of insects. Mammalian prey comprised over 90 percent of the biomass consumed. The flying squirrel (Glaucomvs sabrinus) was the principal prey species (13-48 percent of total biomass consumed), except in dry forest areas, where wood rats (Neotoma fuscipes and N. cinerea became most important (7-78 percent of total biomass). Other important prey included snow- shoe hares (Lepus americanus), red tree voles (Phenacomvs longi- caudus), deer mice (Peromyscus maniculatus), western red-backed voles (Clethrionomys occidentalis), Mazama pocket gophers (Thomomvs mazama), pikas (Ochotona princeps), and small birds.

As you slowly sank into the bog, you’d find yourself surrounded by California pitcherplant, pleated and Mendocino gentians, Labrador tea, western tofieldia, California bog asphodel, sedges, Columbia and Vollmer’s lilies, and Pacific reed grass. Outside of this watery jungle, you would see dry, bare, red rocky slopes and a scattering of Port Orford cedar and Jeffrey pine. Luckily, “muggles” (the non-magical community) don’t need to “apparate” to get to Hunter Creek Bog. We can turn off Highway 101, just south of Gold Beach in Curry County, and drive east about 10.5 miles to visit this public land botanical jewel managed by the Bureau of Land Management (BLM). ACEC Status There are two Areas of Critical Environmental Concern (ACEC) at Hunter Creek: Hunter Creek Bog ACEC and the North Fork Hunter Creek ACEC, which together total about 2,300 acres. In 1982 the Kalmiopsis Audubon Society and the Innominata Garden Club nominated Hunter Creek Bog (Section 13) and Hunter Springs Bog (Section 24) for ACEC status (Bowen and others 1982). In 1994, 570 acres in those sections and 1,730 acres of North Fork Hunter Creek were proposed as a separate ACEC. In 1995, both ACEC proposals were designated, including lands located in Sections 1, 2, 11, 12, 13, 14, and 24, Township 37 South, Range 14 West (BLM 1995).
