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. -

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. -

Aalto, Committee Member Date Dr. Michael R. Mesler, Graduate Coordinator Date Jená Burges, Vice Provost Date ABSTRACT Floristic studies are especially timely since habitat loss is increasing dramatically. From the conservation perspective, it is imperative to document the distribution of plant species in areas that are floristically rich. For this study, I conducted a floristic survey along a 20-mile transect in the Horse Mountain, Grouse Mountain and Board Camp Mountain areas of Humboldt County, California. I also determined the phytogeographical affinities of the taxa I found and made comparisons between my flora and 11 other northwest California floras. Additionally, I made a comparison between my flora and the historical collection of Joseph Prince Tracy, a botanist who collected extensively in the same area during the early 1900s. I used an informal stratified sampling regime to cover the different vegetation types within the study area. Five hundred and forty-eight species were identified from 77 vascular plant families, including 18 California Native Plant Society listed taxa and 28 taxa endemic to northwest California. -

The Siskiyou Loop: Discovery Tour
The Siskiyou Loop: Discovery Tour Would you like to take a trip of discovery into the mountains near Medford and Ashland? The Siskiyou Loop is an 85-mile long drive that will take you from the Medford-Ashland area – via Jacksonville and the equally historic Applegate Valley – up along the scenic crest of the rugged Siskiyou Mountains, and return you to Interstate Five and the Rogue River Valley. Along this self-guided “discovery tour” through parts of two National Forests you will: z view managed forestlands; z observe interesting geology, flora, and fauna; z visit historic sites; z and see some beautiful, near-pristine backcountry.

Port-Orford-Cedar (Chamaecyparis Lawsoniana)
Port-Orford-Cedar (Chamaecyparis lawsoniana) Northern California Climate Change Vulnerability Assessment Synthesis An Important Note About this Document: This document represents an initial evaluation of vulnerability for Port-Orford-cedar in northern California based on expert input and existing information. Specifically, the information presented below comprises vulnerability factors selected and scored by regional experts, relevant references from the scientific literature, and peer-review comments and revisions (see end of document for a glossary of terms and brief overview of study methods). The aim of this document is to expand understanding of habitat vulnerability to changing climate conditions, and to provide a foundation for developing appropriate adaptation responses. Peer reviewers for this document included Everett Hansen (Oregon State University), Richard Sniezko (U.S. Forest Service), and Donald Zobel (Oregon State University). Vulnerability scores were provided by Eureka workshop participants.
