y The quality of water from forest lands in Oregon generally is very high, although some dissolved, particulate, and biological constituents are commonly present. y High sediment levels can occur in streams in undisturbed forest watersheds in Oregon, especially during large storms that cause natural erosion on hillslopes or in stream channels. According to, the concentrations of substances and their biological, physical and chemical effects are the basic criteria in the determination of water quality. Forest in upstream watersheds is the best land cover to maximize water quality and support constant yield for agricultural and domestic uses, preventing floods in downstream areas.
The Oregon Forest Practices Act was the first in the United States to include provisions for the protection of water quality and fish habitat. Presently, regulations for harvest along small, perennial, non fish-bearing streams are less stringent than along fish bearing streams or streams designated for drinking water . Climate projections were made for three intensively studied watersheds in the West, including Niwot Ridge and Loch Vale, Colorado and Andrews Experimental Forest, Oregon. Effects of climate change on streamflow in high-elevation alpine-tundra and subalpine forest watersheds of the Rockies are distinct from those in northern hardwood forests in.

Paired watershed studies, along with process measurements, plot-scale studies, and hydrologic modeling, are important elements of forest hydrology. However, study plots and paired watershed studies have.

Fertilization and Water Quality by DUANE G. MOORE Forestry Sciences Laboratory Pacific Northwest Forest and Range Experiment Station Forest Service, U.S. Department of Agriculture Corvallis, Oregon Fertilization of forested watersheds is a rapidly growing management practice in many areas of the United States.

Request PDF | Water Quality Effects of Clearcut Harvesting and Forest Fertilization with Best Management Practices | Nine small ( ha) and four large ( ha) watersheds were instrumented in. ABSTRACT: Forest land managers are concerned about the effects of logging on soil erosion, streamflow, and water quality and are promoting the use of Best Management Practices (BMPs) to control impacts.
To compare the effects of BMP implementation on streamwater quality, two of three small watersheds in Kentucky were harvested in andone with BMPs, the other without Cited by: 1. Introduction. The quality of water draining forests is typically higher than the quality of water draining areas under any other major land use (USEPA, ).In the United States, the concentrations of total nitrogen (N) and phosphorus (P) in water draining agricultural areas are about nine times greater than concentrations found in forested streams (Omernik, ).
Urea fertilization of natural forest: Effects on water quality. Forest Ecol. Manage., 1: Urea at the rate of kg N/ha was applied by helicopter to a ha watershed covered with a natural stand of balsam fir (Abies balsamea Mill.), white spruce (Picea glauca Moench.) and paper birch (Betula papyrifera Marsh.), 80 km from Quebec City.
fertilization of agricultural lands on water quality (Stanford, England, and Taylor ). This concern is being extended to all fertilizer use, including fertilization of forested watersheds. In addition to possible detrimental effects on water quality, the use of chemical fertilizers to increase growth of forest trees may affect water yield.
Forest roads can be a major source of muddy water in a forest. A properly designed, built and maintained forest road diverts rainwater from the road onto the forest floor, where it can be absorbed and filtered before flowing into a stream.
Well-engineered and properly located forest roads and stream crossings reduce effects on water quality. Nine small (25 ha) and four large (70– ha) watersheds were instrumented in to evaluate the effects of intensive silvicultural practices with best management practices (BMPs) on runoff and stream water quality in the Western Gulf Coastal Plain of East Texas, USA.
Nutrient release from three small watersheds in Oregon's Coast Range was monitored for 2 years before and 2 years after logging.
One watershed, Flynn Creek ( ha), served as. The forest surrounding Jetty Creek, the water supply for the town of Rockaway Beach on Oregon’s north coast, has been logged heavily. Some residents there say the timber harvests have impacted. Forest fertilization increased by % in the southeastern United States from toand the total acreage fertilized in the Southeast exceeds the forest area fertilized in the rest of the world.
This has generated concern that intensive forest practices, including fertilization, may negatively impact water quality in forest streams.
Watersheds. Oregon’s approach has been to foster the U.S. Forest Service office or a soil-and-water conserva-tion district) or a nonprofit organization (e.g., a water-shed council)—but implemented by contractors.1 The • The effects of forest and watershed restoration con.
The mission of the Watersheds Research Cooperative is to conduct research on the effects of current and expected forest practices on intensively managed commercial forestland on water quality, fisheries and other water-related values. With 80 percent of the freshwater resources in the United States originating in forests, having healthy forests is critical to having clean water.
The quality of water draining from forested watersheds is typically the highest in the country. Forests absorb rainfall, refill aquifers, slow and filter stormwater runoff, reduce floods, and provide habitat for fish and wildlife. Oregon House Billwhich took effect in Januaryallows forest landowners to have wildlife food plots.
The statute that arose from the bill is Oregon Revised Statute (ORS) This statute requires the Board of Forestry to adopt rules to allow wildlife food plots to be an approved activity under the Forest Practices Act (FPA).
vide insights on the effects of forest fertilization on water quality. Forest fertilization can lead to modest increases in streamwater nutrient concentrations. The greatest increases come from 1) direct application of fertilizer to streams, 2) use of NO 3-forms of fertilizer, and.
As one approach, we developed a risk assessment (toxicity and exposure) for salmon from water quality changes following timber harvesting. Toxicity relationships for nitrate-nitrogen (as an LC50) using chloride, suspended sediment, and exposure were developed from the literature and data from the Alsea Watershed Study in the Oregon Coast Range.
This report reviews literature on effects of forest fertilization on water quality, emphasizing Cascade streams in the Pacific Northwest and pos-sible ecological effects on aquatic systems in those streams.
Although the focus is on streams, the ini-tial discussion describes interactions of fertilizers. The impact on water quality by pesticides is associated with the following factors: Active ingredient in the pesticide formulation. Contaminants that exist as impurities in the active ingredient.
Additives that are mixed with the active ingredient (wetting agents, diluents or solvents, extenders, adhesives, buffers, preservatives and emulsifiers). Shepard, J.P. Effects of forest management on surface water quality in wetland forests.

Bethesda, MD: Society of American Foresters: – Background Enhancing water provision services is a common target in forest restoration projects worldwide due to growing concerns over freshwater scarcity.
However, whether or not forest cover expansion or restoration can improve water provision services is still unclear and highly disputed. Purpose The goal of this review is to provide a balanced and impartial assessment of the impacts of.
