Planning Biotechnical Streambank Protection, Gary W. Wells Mar 2002

Planning Biotechnical Streambank Protection, Gary W. Wells

Agroforestry Notes (USDA-NAC)

This note is designed to help planners determine the appropriateness of biotechnical alternatives for streambank stabilization. Biotechnical approaches utilize plants as the primary structural components to provide an alternative or complement to concrete, rock and other materials. Even though various biotechnical techniques have been developed to utilize the ability of plants to stabilize slopes, there are situations where these techniques are not an appropriate choice.

Part I of this article covered the basics of compounding and discounting. You were introduced to forestry investment analysis. However, several complications were not discussed. What about inflation, taxes, and risk? Part II addresses basic complications. It also includes more detailed forestry investment analyses.


A Survival Model For Unthinned Loblolly Pine Plantations That Incorporates Non-Planted Tree Competition, Site Quality, And Incidence Of Fusiform Rust, Y. J. Lee, Dean W. Coble Jan 2002

A Survival Model For Unthinned Loblolly Pine Plantations That Incorporates Non-Planted Tree Competition, Site Quality, And Incidence Of Fusiform Rust, Y. J. Lee, Dean W. Coble

Articles

Future biomass yields are functionally related to the number of trees surviving at a given age. A stand level survival model was developed that incorporates competition of non-planted trees, site quality, and the incidence of fusiform rust (Cronartium quercuum [Berk.] Miyabe ex Shirai f. sp. fusiforme). The model consists of a system of two equations, one of which represents the number of surviving trees infected by fusiform rust while the other represents the number of trees not infected by fusiform rust. Data from unthinned loblolly pine (Pinus taeda L.) plantations in East Texas were used to fit and evaluate the …


Fuel Loading Prediction Models Developed From Aerial Photographs Of The Sangre De Cristo And Jemez Mountains Of New Mexico, Usa, Kelly Scott, Brian P. Oswald, Kenneth W. Farrish, Daniel Unger Jan 2002

Fuel Loading Prediction Models Developed From Aerial Photographs Of The Sangre De Cristo And Jemez Mountains Of New Mexico, Usa, Kelly Scott, Brian P. Oswald, Kenneth W. Farrish, Daniel Unger

Faculty Publications

Fuel load prediction equations that made use of aerial photographs were developed for Mixed Conifer, Ponderosa Pine (Pinus ponderosa Dougl. ex Laws.) and Pinyon-Juniper (Pinus edulis Engelm.)-(Juniperusmonosperma Engelm.) cover types from one-time measurements made in the Santa Fe watershed (SFWS) located in the Sangre de Cristo Mountains of northern New Mexico, and at Los Alamos National Laboratory (LANL) located in the Jemez Mountains of northern New Mexico. The results of the watershed data set were favorable and exhibited a high degree of relative accuracy. The results from the LANL data set did not share the same degree of accuracy, …


Red-Cockaded Woodpecker Foraging Behavior In Relation To Midstory Vegetation, D. Craig Rudolph, Richard N. Conner, Richard R. Schaefer Jan 2002

Red-Cockaded Woodpecker Foraging Behavior In Relation To Midstory Vegetation, D. Craig Rudolph, Richard N. Conner, Richard R. Schaefer

Faculty Publications

Red-cockaded Woodpeckers (Picoides borealis) nest and forage in pine-dominated forests. Research indicates that substantial hardwood midstory encroachment is detrimental to Red-cockaded Woodpecker populations, although the exact mechanisms are unknown. We examined foraging behavior in relation to midstory between August 1989 and February 1990. Red-cockaded Woodpeckers foraged at greater heights in areas of taller and denser midstory in the loblolly-shortleaf pine (Pinus taeda and P. echinata, respectively) habitat, but not in longleaf pine (P. palustris) habitat with less-developed midstory vegetation than typical of loblolly-shortleaf pine habitat. In addition, Red-cockaded Woodpeckers concentrated foraging activities in or adjacent to forest stands or openings …


Engineered Wood Products May Dramatically Impact Timber Markets In The Southern U.S., Steven H. Bullard Jan 2002

Engineered Wood Products May Dramatically Impact Timber Markets In The Southern U.S., Steven H. Bullard

Faculty Publications

"Change is inevitable, except from a vending machine." This bumper sticker saying relates well to recent developments in fo rest products and their potential impact on forest landowners in the South.

Change is inevitable-and very important changes are occurring today in how the trees-we grow are processed and used in the US and around the world. These changes have the potential for very dramatic changes in timber markets in the US South, where there are millions of acres of commercial forestland. Changes in timber markets, of course, affect landowners' profits from timber growing, and they may therefore impact our objectives …

Effects Of Excessive Nitrogen Deposition On Foliar Nutrient Dynamics, Nutrient Concentrations, And Nutrient Ratios In A Central Appalachian Hardwood Forest, Sarah Beth Burdette Jan 2002

Effects Of Excessive Nitrogen Deposition On Foliar Nutrient Dynamics, Nutrient Concentrations, And Nutrient Ratios In A Central Appalachian Hardwood Forest, Sarah Beth Burdette

Theses, Dissertations and Capstones

Many forested systems of the eastern US are becoming significantly nitrogen (N) saturated due to chronic N deposition from the atmosphere. Nitrogen saturation has the potential to alter important internal plant processes, such as nutrient cycling. While extensive research has been conducted on the responses of soil to N saturation, considerably less research has focused on the response of plant nutrient dynamics, nutrient concentrations, and nutrient ratios to excess N. Research was conducted on two watersheds at the Fernow Experimental Forest in West Virginia: WS3 (fertilized with ammonium sulfate annually since 1989) and WS7 (untreated control). Presenescent and senesced leaves …


A Gis Approach For The Abandoned Mine Inventory With Haul Roads Of The Monongahela National Forest To Provide A Comparative Analysis Of Usfs/Usace Collection Procedures And Image Basemap Selection For Cartographic Representation, John R. Ferguson Ii Jan 2002

A Gis Approach For The Abandoned Mine Inventory With Haul Roads Of The Monongahela National Forest To Provide A Comparative Analysis Of Usfs/Usace Collection Procedures And Image Basemap Selection For Cartographic Representation, John R. Ferguson Ii

Theses, Dissertations and Capstones

The Monongahela National Forest spans 10 counties in eastern central West Virginia. It has been an area of high mining and timbering activities throughout much of the early to mid twentieth century. As a result, the United States Forest Service (USFS) has focused reclamation and remediation efforts on the abandoned mine land areas. Much of the area has been subjected to mining after effects such as acid mine drainage, structural remains, gob/spoil piles, garbage piles, mine portals, and highwalls. In 1998 the USFS contracted with the U.S. Army Corps of Engineers (USACE) to locate these mining remains and provide a …


Wildland Fire In Ecosystems Effects Of Fire On Air, David V. Sandberg, Roger D. Ottmar, Janice L. Peterson, John Core Jan 2002

Wildland Fire In Ecosystems Effects Of Fire On Air, David V. Sandberg, Roger D. Ottmar, Janice L. Peterson, John Core

Joint Fire Science Program Synthesis Reports

This state-of-knowledge review about the effects of fire on air quality can assist land, fire, and air resource managers with fire and smoke planning, and their efforts to explain to others the science behind fire-related program policies and practices to improve air quality. Chapter topics include air quality regulations and fire; characterization of emissions from fire; the transport, dispersion, and modeling of fire emissions; atmospheric and plume chemistry; air quality impacts of fire; social consequences of air quality impacts; and recommendations for future research.
