Collaborative Research: Developing Methods To Study Age-Related Changes In The Physiology Of Forest Trees, Michael S. Greenwood Nov 2004

Collaborative Research: Developing Methods To Study Age-Related Changes In The Physiology Of Forest Trees, Michael S. Greenwood

University of Maine Office of Research Administration: Grant Reports

Trees continue to increase in size and complexity over life spans that may last many centuries, and each year the growing regions of their shoots produce new foliage and reproductive structures. As they grow older and larger, forest trees appear to grow more slowly, produce thicker foliage and more reproductive structures. These changes are likely to be associated with age-related declines in the growth rates of forest stands, which occur before the mid-point of the lifespan of important timber species. Although similar patterns of age- and size-related change in the morphology and physiology of foliage have been described for numerous …

Project Report No. 65, Stumpage Price Trends Of Sawtimber And Pulpwood In East Texas And Louisiana, Dean W. Coble, Shiaolin Cheng

Informal Project Reports

A fifteen-year stumpage price update and analysis for pine and hardwood in East Texas are reported. Thepricesofsawtimberandpulpwoodare presented for both pine and hardwood plantations by using 1988 to 2003 stumpage prices from the Texas Forest Service and Louisiana Department of Agriculture. Timber prices increased steadily from 1988 to the late 1990's, peaked, then declined into 2003 for both Louisiana and Texas. Louisiana prices, though, have remained higher than those for Texas.


The Red-Cockaded Woodpecker: Interactions With Fire, Snags, Fungi, Rat Snakes, And Pileated Woodpeckers, Richard N. Conner, Daniel Saenz, D. Craig Rudolph Nov 2004

The Red-Cockaded Woodpecker: Interactions With Fire, Snags, Fungi, Rat Snakes, And Pileated Woodpeckers, Richard N. Conner, Daniel Saenz, D. Craig Rudolph

Faculty Publications

Red-cockaded woodpecker (Picoides borealis) adaptation to fire-maintained southern pine ecosystems has involved several important interactions: (I) the reduction of hardwood frequency in the pine ecosystem because of frequent tires, (2) the softening of pine heartwood by red heart fungus (Phellinus pini) that hastens cavity excavation by the species, (3) the woodpecker's use of the pine's resin system to create abarrier against rat snakes (Elaphe sp.), and (4) the woodpecker as a keystone cavity excavator for secondary-cavity users. Historically, frequent, low-intensity ground tires in southern pine uplands reduced the availability of dead trees (snags) that are typically used by other …

The Influence Of Hurricane Winds On Caribbean Dry Forest Structure And Nutrient Pools, Skip Van Bloem, Ariel E. Lugo, Rebecca Ostertag, Maria Rivera Costa, Ivelisse Ruiz Bernard, Sandra Molina Colón, Miguel Canals Mora

Publications

In 1998, we measured the effects of Hurricane Georges after it passed over long‐term research sites in Puerto Rican dry forest. Our primary objectives were to quantify hurricane effects on forest structure, to compare effects in a large tract of forest versus a series of nearby forest fragments, to evaluate short‐term response to hurricane disturbance in terms of mortality and sprouting, and to assess the ability of hurricanes to maintain forest structure. We sampled damage from 33 plots (1.3 ha) across a 3000‐ha tract of forest as well as in 19 fragments. For stems with 2.5‐cm minimum diameter, 1004 stems/ha …

Watershed Scale Impacts Of Buffers And Upland Conservation Practices On Agrochemical Delivery To Streams, Thomas G. Franti, Dean E. Eisenhauer, Mary Carla Mccullough, L. M. Stahr, Mike Dosskey, D. D. Snow, Roy F. Spalding, Alan L. Boldt

USDA Forest Service / UNL Faculty Publications

Conservation buffers are designed to reduce sediment and agrichemical runoff to surface water. Much is known about plot and field scale effectiveness of buffers; but little is known about their watershed scale impact. Our objective was to estimate the watershed scale impact of grass buffers by comparing sediment and agrichemical losses from two adjacent 141-165 hectare watersheds, one with conservation buffers and one without. Rainfall derived runoff events from 2002-2003 were monitored for water runoff, TSS, phosphorous and atrazine loss. A conservation-watershed included 0.8 km of grass buffers and 0.8 km of riparian forest buffer, ridge-tilled corn, corn-beans-alfalfa rotation, terraces …


Sp627 Identification And Control Of Non-Native Invasive Forest Plants In Tennessee, The University Of Tennessee Agricultural Extension Service Sep 2004

Sp627 Identification And Control Of Non-Native Invasive Forest Plants In Tennessee, The University Of Tennessee Agricultural Extension Service

Forestry, Trees, and Timber

Invasive, exotic plants can cause significant displacement of native vegetation. But exactly what are exotic plants? What makes them invasive? To find out, let’s start with some basic definitions.

The vegetation historically found in a local area is termed native vegetation. These plants have traditionally been found in the area and are well-suited to maintain themselves in their environs. Exotic plants are those plants found in a particular area, but which originate from another continent or country. These plants can also be referred to as non-native. However, non-native plants are not always exotic. Non-native plants may also be native …


Recognizing And Overcoming Difficult Site Conditions For Afforestation Of Bottomland Hardwoods, William Conner, J A. Stanturf, E S. Gardiner, C J. Schweitzer, A W. Ezell Sep 2004

Recognizing And Overcoming Difficult Site Conditions For Afforestation Of Bottomland Hardwoods, William Conner, J A. Stanturf, E S. Gardiner, C J. Schweitzer, A W. Ezell

Publications

In the last decade, about 370,000 acres (150,000 ha) of economically marginal
farmland in the Lower Mississippi Alluvial Valley (LMAV) have been restored to
bottomland hardwood forests (Stanturf and others 1998, King and Keeland 1999,
Schoenholtz and others 2001). Planting of this considerable acreage is due to several federal programs, such as the Wetlands Reserve Program (WRP), that assist landowners by financing afforestation (Figure 1). Unfortunately, these operational plantings have not performed as well as smaller plantings or research plots (Stanturf and others 2001a). For example, a recent survey of WRP plantings in westcentral Mississippi revealed that more than 90 …


Where Should Buffers Go? Modeling Riparian Habitat Connectivity In Northeast Kansas, Gary Bentrup, Todd Kellerman Sep 2004

Where Should Buffers Go? Modeling Riparian Habitat Connectivity In Northeast Kansas, Gary Bentrup, Todd Kellerman

USDA Forest Service / UNL Faculty Publications

Through many funding programs, riparian buffers are being created on agricultural lands to address significant water quality problems. Society and landowners are demanding many other environmental and social services (e.g., wildlife habitat and income diversification) from this practice. Resource planners therefore need to design riparian buffer systems in the right places to provide multiple services. However, scientific guidance for this is lacking. We developed a geographic information system (GIS)-based assessment method for quickly identifying where buffers can be established to restore connectivity of riparian areas for the benefit of terrestrial wildlife. An area in northeastern Kansas was selected to evaluate …


Historical Evidence Of Riparian Forests In The Great Plains And How That Knowledge Can Aid With Restoration And Management., Elliot West, Greg Ruark Sep 2004

Historical Evidence Of Riparian Forests In The Great Plains And How That Knowledge Can Aid With Restoration And Management., Elliot West, Greg Ruark

USDA Forest Service / UNL Faculty Publications

While some argue that the Great Plains were dominated by grasslands and that riparian woodlands were rare, others contend that trees would logically have occurred in riparian areas due to favorable microenvironment conditions. Historically, what native plant communities were found in riparian zones of the Great Plains? The answers to this question depend to a large extent on what time period is used as a reference of pre-settlement conditions.

The U.S. Fish and Wildlife Service (1981) drew upon conditions in 1905 for insight and concluded that trees were “wholly absent” or consisted of scattered cottonwood and willow. However, such a …


Working Trees For The 2002 Farm Bill Aug 2004

Working Trees For The 2002 Farm Bill

Working Trees (USDA-NAC)

The Farm Security and Rural Investment Act of 2002 (Farm Bill) has been hailed as the single most significant commitment toward conservation on private lands in the Nation's history. Landowners can benefit from a portfolio of voluntary services. The conservation provisions can assist farmers and ranchers in meeting environmental and production challenges on their land. This legislation modifies existing programs and creates some new programs. The 2002 Farm Bill provides many opportunitiesy to enhance the long-term quality of our environment and the conservation of our natural resources.

Agroforestry has come a long way in the United States in the last …

Restoration Of Aspen Woodland Invaded By Western Juniper: Applications Of Partial Cutting And Prescribed Fire, Jonathon D. Bates, Richard F. Miller

Aspen Bibliography

Western juniper (Juniperus occidentalis spp. occidentalis) woodlands are rapidly replacing quaking aspen (Populus tremuloides) stands throughout the northern Great Basin. Aspen stands provide important habitat for many wildlife species and contain a high diversity of understory shrubs and herbaceous species. We studies two juniper removal treatments to restore aspen woodlands in Kiger Canyon on Steens Mountain, Oregon.


Green-Ampt Infiltration Parameters In Riparian Buffers, L. M. Stahr, Dean E. Eisenhauer, M. J. Helmers, Mike Dosskey, Thomas G. Franti Aug 2004

Green-Ampt Infiltration Parameters In Riparian Buffers, L. M. Stahr, Dean E. Eisenhauer, M. J. Helmers, Mike Dosskey, Thomas G. Franti

USDA Forest Service / UNL Faculty Publications

Riparian buffers can improve surface water quality by filtering contaminants from runoff before they enter streams. Infiltration is an important process in riparian buffers. Computer models are often used to assess the performance of riparian buffers. Accurate prediction of infiltration by these models is dependent upon accurate estimates of infiltration parameters. Of particular interest here are Green-Ampt infiltration parameters, satiated hydraulic conductivity (Ko) and wetting front suction (hf). The objectives of this research were to (i) modify the Smith sorptivity procedure so that it can be used to estimate Green-Ampt infiltration parameters, (ii) Determine the relative …

Simulating The Dynamics Of Linear Forests In Great Plains Agroecosystems Under Changing Climates, Qinfeng Guo, James R. Brandle, Michele M. Schoeneberger, D. Buettner

USDA Forest Service / UNL Faculty Publications

Most forest growth models are not suitable for the highly fragmented, linear (or linearly shaped) forests in the Great Plains agroecosystems (e.g., windbreaks, riparian forest buffers), where such forests are a minor but ecologically important component of the land mosaics. This study used SEEDSCAPE, a recently modified gap model designed for cultivated land mosaics in the Great Plains, to simulate the effects of climate change on the dynamics of such linear forests. We simulated the dynamics of windbreaks with different initial planting species richness and widths flight changes as the selected resulting factor) using current climate data and nested regional …

Fire Regimes And Resultant Forest Structure In Native Año Nuevo Monterey Pine (Pinus Radiata) Forest, California, Scott L. Stephens, Douglas D. Piirto, Domenico F. Caramagno

Natural Resources Management and Environmental Sciences

Native Monterey pine (Pinus radiata) forests occur in five populations on the west coast of North America. High severity fire has been reported to be the main disturbance agent that initiates seedling establishment for this species. To investigate the impacts of fire in this ecosystem, age structure and fire history data were collected from the native Ano Nuevo Monterey pine forest near Santa Cruz California. Stump cross-sections were removed from 10 randomly placed openings, and each was dated to determine tree age and fire history. Average mean fire return intervals were 11.2-20.1 y. Fifty-one percent of the Monterey …

Pb1650 Understanding Log Scales And Log Rules, The University Of Tennessee Agricultural Extension Service Jun 2004

Pb1650 Understanding Log Scales And Log Rules, The University Of Tennessee Agricultural Extension Service

Forestry, Trees, and Timber

A necessary step in determining the value of timber at the mill is establishing the estimated volume by standard scaling practices. Examples of scaling practices include measuring the weight of pulpwood to estimate the volume and measuring the dimensions of hardwood sawlogs, along with applying a log rule to determine how much lumber can be sawn from the log. This publication describes common methods of log scaling and log rules used in Tennessee.

Scaling estimates the log volume on a board foot, cubic foot, linear foot or cord basis. In scaling pulpwood or chipwood, the volume of available material is …
