During the 2016 greater sage-grouse breeding season, 1,908 aerial and ground lek surveys were conducted at 768 individual lek sites comprising 501 lek complexes. Surveys were conducted at 66.0% of known lek sites in the state, which was the greatest proportion of leks ever surveyed in Oregon. Survey effort during...
Counts of males attending leks in the spring have been the primary means employed by states to monitor status of greater sage-grouse (Centrocercus urophansianus) populations for over 75 years. Despite limitations and potential biases, lek count data remain the only long-term, range-wide dataset available for evaluating trends in sage-grouse populations....
In 2013, the U.S. Fish and Wildlife Service (USFWS) Conservation
Objectives Team (COT) identified wildfire and the associated
conversion of low- to mid-elevation sagebrush (Artemisia tridentata)
habitats to invasive annual grass-dominated vegetation communities
as the two primary threats to the sustainability of Greater sage-grouse
(Centrocercus urophasianus, hereafter GRSG) in the...
This white paper outlines interim guidance for development of Oregon Department of Fish and Wildlife habitat mitigation recommendations associated with renewable energy development and associated infrastructure or other landscape scale industrial-commercial developments in greater sage-grouse habitat in Oregon. This guidance is interim until empirical data are available that quantify the...
Greater sage-grouse (Centrocercus urophasianus) were once found in most grassland and sagebrush (Artemisia spp.) habitats east of the Cascades in Oregon. European settlement and conversion of sagebrush steppe into agricultural production led to extirpation of the species in the Columbia Basin by the early part of the 1900s, but sagebrush...
PowerPoint slides and documents from a meeting between the Oregon Dungeness Crab Commission, the Oregon Dept. of Fish and Wildlife and crab fishers at the Best Western, Agate Beach Inn on July 28-29, 2009. Topics covered included pot limits, derelict gear, vessel safety, crab logbooks, the Washington State buyback program,...
"With the implementation of the recreational shellfish license in 2004, ODFW decided to re-initiate a study of the recreational component of the Dungeness crab fishery. The pilot study was performed to assess the effort and catch of recreational Dungeness crabbers on the Columbia River estuary during the fall and winter...
The Marine Resource Program of the Oregon Department of Fish and Wildlife is headquartered in a building at the Hatfield Marine Science Center. Built in 1970 for 30 personnel, it now houses 52. By the end of 2007 the MRP will need space for 82. The purpose of this report...
PowerPoint slides and documents from a meeting between the Oregon Dungeness Crab Commission, the Oregon Dept. of Fish and Wildlife and crab fishers at the Curry County Fairgrounds on July 30-31, 1997. Topics covered included buoy tags, logbooks, law enforcement, pot limits, the Washington State buyback program, derelict gear and...
The overall goal of the Greater Sage-grouse Comprehensive Conservation Strategy (Strategy) is to maintain and enhance populations and distribution of sagegrouse by protecting and improving sagebrush habitats and ecosystems that sustain these populations. This Strategy outlines the critical need to develop the associations among local, state, provincial, tribal, and federal...
The Oregon Conservation Strategy is an ambitious effort to synthesize the best available data, science, and knowledge into a broad vision and conceptual framework for long-term conservation of Oregon’s native wildlife. It is intended to be a dynamic, living approach that will be adjusted as new information and insights are...
Our project goal is to promote the abundance of the endangered Fender’s blue butterfly (Icaricia icarioides fenderi) by recreating upland prairie habitat in former agricultural land at Finley National Wildlife Refuge, Corvallis, Oregon. To achieve this goal we initiated the following three studies. Study One: Experimental Investigation on the Effectiveness...

This is an Oregon Dept. of Fish and Wildlife exhibit made before the October 7, 2005 meeting of the Oregon Fish and Wildlife Commission. The exhibit contains a briefing on the status of management of the crab fishery, and a proposal for a limited-entry Dungeness crab fishery from 3 to...
This is an exhibit prepared by the Oregon Department of Fish and Wildlife for the Oregon Fish and Wildlife Commission. Prior to November, 2005, ODFW managed a developmental fishery program for commercial harvest of bay clams by scuba divers. This document recommends removing bay clams from the developmental fisheries species...
This report summarizes the recent state of the California Current System (CCS), primarily during the period of April 2004 to January 2005. The report is based on observations made between Oregon and Baja California by various ocean observing programs. The CCS was not forced by any coherent basin-wide processes during...
This project has provided the ODFW Marine Habitat Project with a unique
opportunity to make a comparative examination of the habitats and fish communities of a
heavily fished reef off of Siletz Bay, and a nearly unfished reef off Cape Perpetua. There
are over 17,000 angler trips for groundfish out...
This report describes the state of the California Current System (CCS)—meteorological, physical, chemical, and biological—from January 2003 to the spring of 2004. The area covered in this report ranges from Oregon coastal waters to southern Baja California. Over the past year, most physical, chemical, and biological parameters were close to...
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.
As part of legislation enacted into law in 2001 related
to conservation incentives for private landowners (HB
3564), the Oregon Legislature directed the Oregon
Department of Agriculture and the Oregon Department of
Forestry to review state statutes, rules, policies and programs
that affect landowner decisions to implement conservation
strategies. The...
Our study area includes the three McKenzie populations, and a reintroduced population in the Middle Fork Willamette and tributaries above Hills Creek Reservoir. We monitored bull trout populations in the McKenzie and Middle Fork Willamette basins using a combination of sampling techniques that include spawning surveys, juvenile trapping, electronic fish...
"September, 2001, Updated October, 2002" - note from cover. "This report reviews the Oregon's ocean commercial Dungeness crab fishery.
