The Oregon Coast between Yachats and Newport is a narrow, slightly elevated coastal plain. With the exceptions of basalt rock at Yachats and Seal Rock, the bedrock along this segment of the coast is sedimentary. Several Pleistocene marine terrace levels are discernible at places along the plain, and sand dunes,...
Bold, rocky headlands alternating with long curved beaches, sand spits, and bays -- these are the dominant landforms that make up the more than 40 miles of scenic coastline between Roads End and Tillamook Bay. With the exception of Cape Kiwanda, which is composed of sandstone, the headlands are made...
The 26-mile stretch of shore extending from Florence to Yachats is one of the most rugged and scenic parts of the Oregon Coast. Along most of this part of the coast the shore is bounded by basalt bedrock of varied types. Through differential erosion of the basalt, the many landforms,...

Riparian areas in the Pacific Northwest have traditionally been a source of natural resources, such as timber and grazing, and have been used as transportation corridors and homestead sites. A primary impact of use has been the removal of riparian trees, the crowns and roots of which provide shade and...
The Oregon coast between Yaquina Head and Government Point owes its scenic grandeur to a unique wedding of ancient and recent marine environments. Visitors to Beverly Beach State Park, located in the southern part of this coastal strip, have a rare opportunity to wander along a shoreline that some 15...
Salal is plant species that is native to forestland throughout the PNW and northern California that has been identified as a competitor to early crop tree development. This study consisted of a field and a radioisotope laboratory study to test four commonly used herbicides on salal (imazapyr, triclopyr, glyphosate, and...

As recent interest has grown in the connections between how food is produced, distributed and consumed, and the overall health of food systems for people and the environment, a movement toward localizing food systems has emerged. In Lincoln County, Oregon, citizens, restaurateurs and university extension faculty, among others, have started...
Incidental to his outdoor activities such as farming, fern-picking, and horse logging, Darrel Faxon made 17.4 years of detailed observations at Thornton Creek during 1973-1990. He determined bird presence, not bird abundance, and made about 99,800 records, where a record is one bird species found during one day. Depending upon...
The use of phenoxy herbicides is an established practice in industrial forestry,
particularly in the Pacific Northwest. Forestry herbicide use in this region has often been
controversial. To better understand the spatial patterns of herbicide use and the potential for
human health and environmental impacts, a landscape level perspective is...
The impetus for this Project began in 1968-1973 with birders at the Marine Science Center (MSC). But in the past 10 or so years the focus has shifted to a county group, Yaquina Birders & Naturalists. 120 individuals or couples have each contributed 100 or more records with 51% of...
Hazardous materials data from business and industrial chemical information and incident databases were analyzed to study the types of chemicals located in Linn, Benton, and Lincoln Counties, Oregon. Federal and Oregon Department of Transportation data were analyzed to study traffic patterns and truck and railroad traffic levels. Results indicate more...
This field trip consists of two geologic tours. On Tour 1, the Tertiary sedimentary rocks exposed along the Yaquina River between Newport and Toledo, Oregon, will be examined. This tour will start at the mouth of Yaquina Bay where Miocene sedimentary rocks are exposed and will proceed generally eastward and...
This is a continuation of Faxon and Bayer (1991), which summarized Faxon's 1973-1990 observations. In 1991, Faxon made observations during 168 days and recorded 111 species. Monthly frequencies of occurrence are given for each species.
This article is based on a total of 353 observations, many of which were systematic censuses.
At West Beaver Pond, Llewellyn made 225 observations of waterbirds during 1982-June 1993. He noted a total of 19 taxa; 53% were seen in five or more of the 10 years with many observations....

WATERBIRDS AT PONDS AND FIELDS IN THE SILETZ/LOGSDEN AREA OF LINCOLNCOUNTY
Bob Llewellyn, 1821 Moonshine
Since the 1980s, industrial forest restructuring has resulted in the divestment of industrial timberlands across the U.S. Emerging tenures have benefited from the divestment, including conservation-based tenures that manage for multiple objectives such as restoration, recreation access, and forest and habitat contiguity. Deschutes and Klamath Counties, Oregon, have three proposed...
Most forests and timber in Western Oregon are taxed under the Western Oregon Forest Land and Severance Tax (WOST), a system which is accepted as one that promotes "correct" economic rotation lengths. This study was motivated by the observation that an optional tax with the same stated purpose - the...
612 Harlequin Duck records are given for Lincoln County, and another 74 records are listed for other coastal counties. In Lincoln County, Harlequins are found mostly in winter, there were often more males than females, the most ever counted was 14, and there is no indication that they nested.
In...
Research was conducted in the Oregon Coast Range to address
the concern that conversion of large diameter old-growth forests
to small diameter second-growth forests would lead to reduction
of large woody debris in adjacent stream channels. The objective
of the study was to quantify spatial trends in large woody debris...
The Phase 1 report is an overview of the complex water quantity and quality information and issues specific to Benton County. It is a first step toward assessing and planning for future water quantity and quality within Benton County and provides a template for regional water planning. The report details...
Janet Lamberson noted the presence of birds around her home during 1985-1990. She noted 10-33 species each month, 48-57 species each year, and a total of 72 species overall. 63 species were terrestrial birds, most of which were observed in all six years of her observations.
The semimonthly occurrence for...
This article includes 609 observations, 531 of which were by Llewellyn. This article is an amalgamation of incidental records for various specific and general areas.
In order for proper land use planning to occur in coastal Lincoln County, Oregon, coastal erosion rates should be determined. This has been accomplished by identifying the location of the Lincoln County coast in 1939, 1959 -, and 1973 and measuring the amount of change occurring between the years. The...
The leasing of submerged and submersible lands is emerging as a new marine conservation method. Using a geographic information system, this study: (1) examines the suitability of estuary tideland sites for conservation leasing in Lincoln County, Oregon, and (2) explores the relationship between adjacent terrestrial land use zones and the...
The purpose of this watershed assessment is to inventory and characterize watershed conditions of the Miami River watershed and to provide recommendations that address the issues of water quality, fisheries and fish habitat, and watershed hydrology. This assessment was conducted by reviewing and synthesizing existing data sets and some new...
The purpose of this study of the Lyons flora is to determine the age and paleoecology of the flora through the examination and identification of the fossil plant species of the flora. The plant fossils comprising the Lyons flora were collected from a locality in the upper Thomas Creek area,...
