- Determining the Value of an Orchard Tree
-
Determining the value of an orchard tree that has been destroyed by natural or unnatural causes is required for tax and insurance purposes and for Federal/State agricultural assistance programs. Coming up with reliable estimates is not simple and can be very expensive when hiring consultants. The purpose of this article is to provide step-by-step instructions for using the agecon-trec software program to estimate the value of a tree that has been destroyed.
- Timber and the Economy of Alabama
-
Alabama's first residents called themselves "the thicket clearers," or "AlaBamas." The forest, once viewed as an impediment to agriculture, is now recognized as the backbone of the state economy. Trees from the forest feed an industry that directly employs more than 49,000 workers, indirectly provides employment for thousands more, and is the leading contributor to the gross state product.
- Making Nitrogen Available to Trees
-
Nitrogen affects the molecular interactions, compound shapes and functions, and the chemical symmetry of life-maintaining materials. In ecosystems, nitrogen is the most precious of elements--carefully used, relentlessly recycled, and biologically hoarded.
- Wood Moisture Content in Georgia Buildings and Offices
-
Wood shrinks and swells with changes in moisture content. Changing conditions of temperature and humidity in homes and offices affect wood moisture.
- Uptake and Reduction of Nitrogen in Trees
-
Adequate availability of nitrogen in soils is but one of the problems facing trees. Moving nitrogen inside the tree presents a number of unique problems and solutions.

Added: October 31, 2008Managed tree root growth control is required to minimize impacts on infrastructures. To constrain root growth, identification of soil attributes that limit growth is required. By understanding what soil conditions limit growth, various tools and techniques can be used to stop, redirect, or slow tree root elongation. Tree-literacy incorporates soil and tree health into a single concept for quality management.

Added: October 31, 2008The strength of tree stems is dependent upon stem thickness, stiffness, and ability to react to changes in aspects toward gravity and wind events. Materials added farther from the stem center (neutral axis) has a much greater impact on strength (per unit weight), than closer to the center materials. This positioning effect is the mechanic strength advantage seen when comparing hollow tubes and solid rods of equal weight, made of the same material -- the tube can resist force more effectively than the rod without deformation. The geometry of where materials are deposited change the strength for resisting bending and twist (torsion).
- Summary of the Endangered Species Act of 1973
-
The purposes of this Act are: to provide a means whereby the ecosystems upon which endangered and threatened species depend may be conserved; to provide a program for the conservation of such endangered and threatened species; and, to take such steps as may be appropriate to achieve the purposes of the international treaties and conventions of which the United States of America is a part.
- Regenerating Southern Pine in Georgia
-
Pine regeneration is neither a mystery nor hard to accomplish. It simply requires application of appropriate techniques and some advanced planning. Seldom can ``nature'' alone be relied upon to adequately regenerate a pine stand.
- Tree Growth Rate Table: Annual Percentage Growth
-
Trees grow in diameter every year. From the farthest reach of the woody roots to the tips of the twigs, trees expand in girth. This annual growth increment allows trees to respond to changing environmental conditions and react to injuries. The ability of
- Exotic Pest Plants and Their Control
-
The first line of defense against an alien plant takeover is a constant surveillance for new arrivals. Early detection and treatment will minimize efforts and costs that come with treating well-established plants or full-blown infestations. Much more effort is required for successful eradication of established infestations, but it``can still be accomplished with proper treatments described here.

-
A list of references for urban forest inventories.
- New Forest Inventory Statistics for Southeast Georgia
-
Trees are complex reacting organisms which grow in dynamic, rapidly changing environments. Tree biology must provide for defense, reproduction, growth, and control of resources. This publication provides some simple ways of thinking about trees.
- Mulching for a Healthy Landscape
-
For as long as trees have grown in forests, leaves and needles have fallen to the ground and formed a natural protective layer over the soil. This same protection can be given to the plants in our landscapes by mulching.
- Identifying and Measuring Forest Products

- Fertilizing Woody Ornamentals
-
Attractive trees and shrubs are important components in all well-landscaped properties. Planned maintenance and care are essential for keeping them healthy and vigorous. An adequate fertilization program is an important requirement of any good woody-plant maintenance program.
- Fertilizer Choices
-
There are a large number of fertilizers available today. Sometimes it is difficult to choose what type of fertilizer to use, what formulation should be used, and how it should be applied. The number of alternatives are confusing.
- Best Management Practices--Soil & Water Conservation
-
Forestry activities, particularly harvesting, can have serious consequences on soil and water quality. Any good forester is concerned about these impacts. Measures can be taken to preserve soil and water quality and to prevent their undue mixing.
- Behind the Wall of Green: A Close Look at the Forest
-
This publication is an introduction to forest conservation biology in Tennessee with a focus on trees, forests, and forest management and conservation.
- Hazards of the Outdoors
-
Foresters, of all people, know quite well how insects can devastate a forest. However, this guide is not about those insects that kill trees. It's about insects and their kin that can make life miserable for foresters and other people who spend a lot of time outdoors. It is important for persons to know about those species that are medically significant and how to avoid a potentially dangerous encounter with a sting or bite.
