Design and Application of Manufactured All-wood Hillslope Erosion Control Structures

July 31, 2002 / Erosion Control, Forest Concepts Research & Development, Publications, WoodStraw

Abstract The FlowCheck™ hillslope erosion control structure was developed to make it easier to accomplish erosion control on burned-over lands, graded slopes and other disturbed areas. The scientific basis for sediment storage behind wood hillslope structures was developed by the U.S. Forest Service Rocky Mountain Research Station. Forest Concepts, LLC combined the best available science […]

Technical Products from Small Diameter Timber for Habitat Enhancement and Watershed Restoration

March 26, 2002 / Forest Concepts Research & Development, Habitats & Bioengineering, Publications, Siskin Ridge Roundwood

Abstract An under-appreciated outlet for small diameter roundwood is in watershed restoration, environmental, and habitat enhancement programs. Over $2 billion is spent in North America on habitat enhancement and watershed restoration each year. Of that amount, our estimate is that approximately $300 million is spent on materials that could be made from small diameter timber.

Technical Background: Engineered Log Jams

December 31, 2001 / Forest Concepts Research & Development, Habitats & Bioengineering, Publications, Siskin Ridge Roundwood

Introduction Depletion and loss of functional large woody debris from streams and rivers of the Pacific Northwest is identified as a contributor to the decline in salmonid populations. Salmon, bull trout, steelhead and other fish are dependent on large woody debris (LWD) and channel morphology resulting from the presence of LWD for many of their

Application and Functional Performance of Engineered LWD

October 15, 2000 / Forest Concepts Research & Development, Habitats & Bioengineering, Publications, Siskin Ridge Roundwood

Abstract An engineered large woody debris structure has been designed and developed for use in habitat and watershed restoration projects. The structure was designed according to the Appreciative Design method to accommodate readily available wood materials, low-tech manufacturing methods, and volunteer-based installation. Technical features include a high organic surface area, structural integrity in an all-wood

Functional performance of engineered LWD for fish and wildlife habitat enhancement

September 23, 2000 / Forest Concepts Research & Development, Habitats & Bioengineering, Publications, Siskin Ridge Roundwood

Abstract An engineered large woody debris structure has been designed and developed for use in habitat and watershed restoration projects. The ELWd® structure was designed according to the Appreciative Design method to accommodate readily available wood materials, low-tech manufacturing methods, and volunteer-based installation. Technical features include a high organic surface area, structural integrity in an

Near-surface and Subsurface Sensing and Mapping for Site-Specific Operational Decisions: Scoping Paper

June 1, 2000 / Forest Concepts Research & Development, Habitats & Bioengineering, Publications, Siskin Ridge Roundwood

Introduction Operational practice of precision forestry enables improved forest industry competitiveness and heightened environmental performance. The present study explores precision forestry concepts and technologies in the context of forestry, forest management and silviculture. This paper looks primarily at the case of plantation forestry. Many of the concepts and details of precision forestry apply to short-rotation

Recasting Industrial Problems for Use in an Academic Setting

July 16, 1998 / Forest Concepts Research & Development, Publications, Siskin Ridge Roundwood

Abstract Most industrial problems must be recast for use in undergraduate courses. Recasting often includes problem simplification and adaptation to the educational objectives of the course. Requirements for disclosure of proprietary or trade secret information must be avoided. A number of examples are provided in the fields of forest, agricultural and horticultural engineering. About the

Stakeholder Influence on Design of Aquatic Habitats

July 14, 1998 / Forest Concepts Research & Development, Habitats & Bioengineering, Publications, Siskin Ridge Roundwood

Abstract An empirical study was conducted across Washington State to explore the social dynamics of designers and other project participants involved in fish habitat improvement projects. We found compelling evidence of design being a social process that readily accommodated stakeholder needs. Traditional engineering decision making methods were not used in spite of the highly technical

Engineered Large Woody Debris for Aquatic, Riparian and Upland Habitat

July 11, 1998 / Forest Concepts Research & Development, Habitats & Bioengineering, Publications, Siskin Ridge Roundwood

Introduction Over the past 100 years we have witnessed dramatic declines in salmonid populations in the Pacific Northwest. Although hatchery influences, dams, and overfishing have also played significant roles, freshwater habitat loss and degradation is acknowledged to have contributed to the decline of virtually every species of Pacific salmon in western North America (National Research
