Presentation intended to provide basic public information about the U.S. Fish and Wildlife Service's 12-month finding for the greater sage-grouse, conducted pursuant to the 2004 Endangered Species Act.
Summertime wind stress along the coast of the northwestern United States typically exhibits intraseasonal oscillations (ISOs) with periods from ≈15 to 40 days, as well as fluctuations on the 2- to 6-day “weather-band” and 1-day diurnal time scales. Coastal upwelling of cool, nutrient-rich water is driven by extended periods of...
The West Fork Cow Creek Watershed assessment has two goals:
1) To describe the past, present, and potential future conditions that affect water quality and fish habitat within the West Fork Cow Creek Watershed; and
2) To provide a research-based action plan that suggests voluntary activities to improve fish habitat...
This paper provides some background information on coarse to medium scale habitat monitoring techniques and proposes a framework for a statewide system. It is designed for state fish and wildlife agencies and their partners to help them meet the monitoring requirement in the development of wildlife strategies.
The workshop emphasized large-scale conservation planning: the networks of conservation lands that are being planned at state and regional levels across the country. Ideally, this approach will help preserve the country's rich biodiversity by protecting its most viable habitats and species populations. This strategy represents current theories on the application...
Various mollusks, including small bivalves and gastropod snails, are a common food source for intertidal crabs. Prey opening techniques used on hard-shell prey are dependent on claw size and morphology. For example, large, strong claws can crush a snail outright while smaller, weaker claws leave characteristic peels, pulls and upper...
The United States is one of the wealthiest countries in the world, yet accessing enough healthy, fresh food to meet basic nutritional needs is a critical issue faced by millions of Americans. There are a number of reasons for food insecurity in the United States, the primary causes being lack...
The research reported here was conducted to identify interests and needs among various sectors of the Oregon agricultural community regarding sustainable agriculture. The study also sought to gauge potential for establishing a program in Oregon to serve those needs.
The scientific literature on logging after wildfire is reviewed, with a focus on environmental effects of logging and removal of large woody structure. Rehabilitation, the practice of planting or seeding after logging, is not reviewed here. Several publications are cited that can be described as 'commentaries', intended to help frame...
In 1998, forest vegetation was monitored for ozone injury on permanent plots in two Sierra Nevada national forests in California, at three locations in Mount Rainier National Park in Washington, and at 68 forest health monitoring (FHM) locations throughout Washington, Oregon, and California. This was the first year that extensive...
The study area for this assessment is composed of the Alsea, Salmon, Siletz, Yachats, and
Yaquina River watersheds and those watersheds that drain directly to the ocean between
Cascade Head and Cape Creek at Heceta Head (Ocean Tributaries). Wherever possible,
1:24,000 uniform scale geographic information system (GIS) data that covered...
This report has been prepared in support of the Pacific Northwest
Coastal Ecosystems Regional Study (PNCERS) to provide
a summary and compendium of the management of estuaries
in the Pacific Northwest of the United States that lie between Puget
Sound, Washington, and Cape Mendocino, California. Federal, state,
and local government...
This document provides watershed restoration actions proposed to enhance the Coho Salmon population within the Rock Creek / Devils Lake basin in Lincoln County, Oregon. The stream is the principle tributary of Devil’s Lake, a lake of natural origin that opens into the Pacific Ocean at the northern edge of...
The 2003-2005 Biennial Report Volume 2 is an executive summary of Oregon's assessment of the Oregon Coastal Coho Evolutionarily Significant Unit (ESU). The assessment provides a detailed analysis that will inform the pending federal decision on whether to list coho as "threatened" under the Endangered Species Act.
Sections of Volume...
The report summarizes basin level accomplishments and investments related to water quality improvements, fish recovery, and watershed
health. The report also provides an overview of state agency actions
and recommendations to enhance the effectiveness of the Oregon
Plan.
This is the fourth report on the Oregon Plan for Salmon and Watersheds. The first three reports focused on people – their
stories and their efforts to restore watershed health and recover listed fish species. While these earlier reports contained
what little information was available regarding the quantitative aspects of...
The prey consumption rates of two estuarine crab species were compared: the introduced Carcinus maenas and the native Cancer magister. Similar sized crabs of each species were placed into individual perforated plastic boxes and then placed in a seawater table. Each crab was offered 50 Mytilus trossulus mussels (15-25mm) per...
