The condition of watersheds on our National Forests

Science Spotlights Posted on: August 21, 2015
Given the continuing concern over nonpoint-source pollution, Rocky Mountain Research Station scientists sought to understand how the risk of water quality impairment from nonpoint sources varies across the nearly 3,700 fifth-level watersheds in the U.S. containing lands of the National Forest System.

Effects of historic forest disturbance on water quality and flow in the Interior Western U.S

Publications Posted on: August 18, 2015
Water quality and flow is affected my many complex factors in the Interior Western U.S. While many studies focus on individual water parameters response to a limited number of changing conditions, little work looks at long term effects of diverse forest disturbances on a broader array of water quality and flow metrics. The U.S.

Water quality impacts of forest fires

Publications Posted on: August 12, 2015
Forest fires have been serious menace, many times resulting in tremendous economic, cultural and ecological damage to many parts of the United States. One particular area that has been significantly affected is the water quality of streams and lakes in the water thirsty southwestern United States.

Integrating pixel- and polygon-based approaches to wildfire risk assessment: Application to a high-value watershed on the Pike and San Isabel National Forests, Colorado, USA

Publications Posted on: July 28, 2015
We develop a novel risk assessment approach that integrates complementary, yet distinct, spatial modeling approaches currently used in wildfire risk assessment.

Water quality in New Zealand's planted forests: A review

Publications Posted on: June 02, 2015
This paper reviewed the key physical, chemical and biological water quality attributes of surface waters in New Zealand’s planted forests. The purpose was to: a) assess the changes in water quality throughout the planted forestry cycle from afforestation through to harvesting; b) compare water quality from planted forests with other land uses in New Zealand; and c) identify knowledge gaps and opportunities for future research.

A mathematical model of salmonid spawning habitat

Publications Posted on: May 14, 2015
A simulation model [Salmonid Spawning Analysis Model (SSAM)I was developed as a management tool to evaluate the relative impacts of stream sediment load and water temperature on salmonid egg survival. The model is for estimating acceptable sediment loads to spawning habitat that may result from upland development, such as logging and agriculture.

Water quality on forest lands

Projects Posted on: May 13, 2015
This research aims to summarize the state of knowledge regarding the effects of forest management on water quality and the value to society of maintaining high quality runoff from forest lands. Economic costs and benefits of water-quality control was also explored.

Wildfire effects on instream sediment loads in the Cache la Poudre watershed following the High Park Fire

Projects Posted on: May 07, 2015
The project evaluates instream sedimentation, sediment sources, and water quality following the High Park fire, including the effectiveness of mulching on reducing instream sediment loads.

Water quality in Colorado

Projects Posted on: May 07, 2015
This study relates Colorado watershed condition with downstream water quality. Water quality is characterized by selected variables (e.g., suspended sediment) measured at a gauge or other inventory point along a river.

Aquatic fate of aerially applied hexazinone and terbuthylazine in a New Zealand planted forest

Publications Posted on: April 15, 2015
Herbicides are used to control competing vegetation during tree establishment, and are often critical to the productivity and economic viability of a planted forest crop. Despite increasing public concern over herbicide use in planted forests and potential impact on the environment, there is limited information on the aquatic fate of many of these herbicides when applied in forests according to standard operational procedures.
