On February 11, 1998, the U.S. Forest Service (USFS) requested that a representative of NIOSH conduct a health hazard evaluation (HHE) to evaluate and compare timber marker's (also called Forestry Technicians) exposures to a new waterborne formulation of tree marking paint developed for use by the U.S. Forestry Service. NIOSH...
An interagency project demonstrated the feasibility of integrating Federal surveys of terrestrial natural resources and offers a vision for that integration. At locations selected from forest inventory and analysis, National forest system Region 6, and national resources inventory surveys in a six-county area in Northern Oregon, experienced teams interpreted and...
On January 5, 2000, the National Institute for Occupational Safety and Health (NIOSH) received a request for a health hazard evaluation (HHE) from the United States Forest Service (USFS), Region 6, Office of Natural Resources. The request listed nausea, rashes, headaches, and dizziness as symptoms reported by Foresters who use...
We describe concepts, rationale, and analytical procedures for characterizing physical habitat in wadeable streams based on raw data generated from methods similar or equal to those of Kaufmann and Robison (in PB99-139156). We provide guidance for calculating measures or indices of stream size and gradient, sinuosity, substrate size and stability,...
Off-channel features such as alcoves and side channels can have important ecological functions for large rivers such as the Willamette River. Some species and age classes of fish may select these features instead of the main channel to feed, avoid predation by other fish, escape fast water, or seek out...
The goal of this project is to recommend a broadly-acceptale efficient and effective methodology for characterizing streamside riparian attributes in forested settings at the site grain for regional monitoring. The authors consider monitoring design in the context of three interacting constraints: ecological functions, capabilities of technologies, and user needs. The...
This paper describes the application of aerial photography and GIS technology to develop flexible and transferable methods for multi-spatial scale characterization and analysis of riparian corridors. Relationships between structural attributes of riparian corridors and indicators of stream ecological conditions are not well established. As part of a research project focused...
This report discusses anticipated problems associated with the pollution of the Umpqua River estuary in Oregon. The method of studying these problems by oceanographical techniques is outlined. Proposed studies relating to the Umpqua River Basin are examined.
Much of the native riparian vegetation of the Willamette Valley, Oregon, has been replaced with agricultural crops or invasive non-native plant species. Detailed information about current Willamette Valley riparian vegetation is generally lacking. Plant specie composition data are useful in a variety of applications, including condition assessment, environmental monitoring and...
