Added: October 31, 2008Assessing potential risks in trees is difficult because of the complex and chaotic nature of gauging tree failures. Tree movements in the wind, and the interactions between/within tree structure and soils, assure a multitude of forces, loads, and stress concentration points will need to be a part of any tree failure model. In order to better understand tree structure and its potential failure, individual components of tree mechanics need to be isolated from the complexity. One mechanical component arising from stem and branch shape is a repeating, damped movement back and forth by the free end--commonly called "sway.''
- Log Homes May Be Where the "Heart-wood" May Be
-
Log homes were the homes of choice for earliest settlers. Some of those homes still stand today, evidence they can be durable. Wood is an excellent building material, too often taken for granted.
- Crown Pruning Effects on Roots
-
Tree growth and development are dependent upon a few basic mechanisms. These mechanisms are responsible for the tree making holistic adjustments to a changing external environment. These basic mechanisms also allow for correlation of processes internally.

- Scientific Classification of Trees: An Introduction for Wood Workers
-
Those who work with wood should be able to distinguish between different woods and be familiar with features that make different kinds of wood react differently to cutting, surfacing, finishing, etc. An obvious first step in accomplishing these tasks is to be able to properly identify and name an unknown wood.

Added: September 24, 2003Forestland owners always face a variety of alternatives regarding managemen of their lands. Each landowner tends to be unique in the way he or she chooses to manage. Some manage intensively for maximum production of the timber resource. Others manage for a variety of benefits in addition to timber maximization, such as production of wildlife habitat or aesthetics. Some do not manage at all.
- Glossary of Terms Used in Timber Harvesting and Forest Engineering
-
Provides definitions for 1,026 words and terms used in timber harvesting and forest engineering, with an emphasis on terms related to timber harvesting operations. Terminology dealing with basic forestry, harvesting equipment, and economics is stressed.
- Sawmill Safety
-
Lately there has been great interest by smaller lumber manufacturing companies in developing safer operations. The purpose of this Wood Products Note is to help these saw mills develop their own safety program.
- Cutting Firewood Safely
-
Cutting your own firewood can be a very worthwhile and rewarding experience if done properly. However, if it is done improperly without regard to safe cutting techniques, serious injury or death can result.

The long term capital gains rate has been reduced significantly--if you sold your timber at the right time and you met the correct holding period requirements. These new rules, plus the information that follows, are some things to keep in mind.
- Selection and Care of Christmas Trees
-
Ever since the first Christmas tree retail lot was set up on the streets of New York City in 1851, Americans have been enjoying the tradition of a live tree to celebrate the holiday season. With the proper selection and care, consumers can enjoy a fresh tree throughout the holiday season.

Added: October 25, 2008Getting trees started correctly in your yard, along streets or in a park is critical to long tree life, easy care and low-cost maintenance. One way to ensure trees are planted correctly is to give them plenty of room to grow. Fruit trees, trees in landscape beds and specimen ornamental trees are grown for different reasons and are not planted the same way as shade and street trees. Here, we deal with shade and street tree planting.

- Estimating Leaning Tree Failures
-
Leaning trees are difficult to assess for catastrophic risk management. In leaning trees, the strength in tension and compression of various portions of the tree above ground, soil strength, and root holding aspects all interact.

- Before You Order Tree Seedlings
-
Good tree planting practices include good planting stock, a well-selected and properly prepared site, proper planting methods, and adequate protection and care of the tree seedlings before and after planting. Failure in any of these planting practices often results in unsatisfactory survival or growth or even in complete failure. This article provides a few questions that should be asked before ordering seedlings.
- Selected Literature: Nitrogen and Tree Growth
-
Nitrogen availability for tree health maintenance and growth is one of the most constraining essential element problems faced by shade and street trees. Effective nitrogen use by trees involves a complex set of interwoven events, processes, and organisms.
- The Economic Value of Open Space
-
While much has been written about the economic value of the environment in general and of open space in particular, the literature is segregated by discipline or methodology. It is therefore difficult to assess the economic value of open space comprehensively. It is even more difficult to apply what is known in a public policy context, where open space holds significant non-monetary value.
- Wildland Urban Interface South
-
Interface South was developed by the USDA Forest Service Southern Research Station and Southern Region to heighten awareness of and provide information about wildland-urban interface issues. Critical interface issues include fire, watershed management, wildlife conservation and management, land use planning and policy, and many more.

- Site Preparation Methods for Regenerating Southern Pines
-
With adequate site preparation, southern pine stands can be regenerated by natural means (using seed from mature trees about to be harvested) or artificial means (planting seedlings or direct seeding).
- Rust Mites In Christmas Trees
-
White pine and Fraser fir Christmas tree growers have occasional problems with the rust mite at higher elevations (>3000 ft). Because damage doesn't occur yearly on high elevation sites, many fir and pine growers do not scout regularly for this pest. They only notice the damage when it is too late to achieve control.
- Overview of Wood-Fired Boiler Use in West Virginia

The objective of this fact sheet is to provide an overview of the amount of wood residue used for fuel in wood-fired boilers and of changes in the use of wood residue for process heat and steam generation between 1992 and 1997.
- Mississippi Forestry Commission

- Border Irrigation System
-
Border irrigation is an old irrigation system used in the western part of the United States to irrigate alfalfa, wheat, other small grains, and sometimes row crops. It is a system where a large volume of water is put in a defined border or bay at the top of the field and guided by the borders down the slope in a uniform wetting pattern to the end of the field.

Added: November 05, 2008A key component in assessing development impacts on trees is the systematic evaluation of damage. Many types of damage occur repeatedly over a site, and from site to site. This constant and repetitive damage comes from fundamental anti-tree and tree-illiterate activities. Under scrutiny of a systematic assessment, these patterned damage forms can be prevented or minimized. Some types of damage (one-time, one-spot, chance occurrences) can be assessed but are difficult to prevent. By attempting to categorize damage, patterns can be recognized and steps taken to minimize tree injury and site degradation. Please note that many development activities and the continued presence of good tree quality are mutually exclusive (spacially and temporally). Decisions must be made early in the planning process to maintain tree quality of life and minimize injury.
