Added: October 31, 2008In storm damage and tree failure assessments, estimating residual strength of damaged trees is difficult and filled with complex, dynamic interactions between the soil, tree, and environment. To help tree specialists appreciate tree biomechanics, this publication was developed to present the maximum relative strength values for two unique, ideal situations--neutral plane faults leaving two stem halves and four stem quarters. This theoretical view can help better understand certain mechanical forces and resistances.
- WOOD IN TRANSPORTATION

details various injury and harm that can befall a tree subjected to mechanical harvesting techniques
- Oaks and Other Trees May Naturally Shed Small Branches
-
From time to time, natural pruning of small branches from oaks and other trees causes alarm to homeowners because they think the tree is dying. This is referred to as branch abscission or cladoptosis. A similar abscission process occurs when deciduous trees shed their leaves each fall.
- Major Watersheds of Georgia
-
The direct or indirect source of water for irrigation, power, industry, domestic use, navigation, and recreation comes from water falling over and flowing down forested watersheds in Georgia. Watersheds are areas where one major river system drains the la...

Added: November 05, 2008Water is essential to tree life. Water is a solvent, transporter, buffer, and reagent for the tree. Water is the most limiting of all essential tree resources. Trees have developed specialized organs, processes, and surfaces to use and conserve water carefully. The value of water lies with its chemical properties, physical reactions, and biological uses. This publication will review what is water, and how it supports life through its properties.
- Timber Harvest Tax: Who Pays, When, Where and How Much?
-
Since 1992, timber value is no longer added to the value of the land in the county tax digest. Timber and land are each a separate class of property and are taxed differently.

- Seasoning of Wood
-
Seasoning is a costly and time consuming process and would not be employed except in special cases unless there were valid reasons why it is required.
- How Forest Trees Grow
-
Knowing how forest trees grow can help woodland owners predict yeilds. Being able to understand the growing cycles of different trees will also help the owner decide when and how to plant, thin and prune trees to increase wood production.
- Growing Christmas Trees on Reclaimed Surface-Mined Land
-
Christmas tree production can be an excellent use for reclaimed mined lands in Virginia. Most species do quite well on mine soils because they are more tolerant of the acid, infertile, and droughty conditions than agricultural or horticultural crops, yet they do respond to active management.

Added: November 05, 2008Trees constantly lose water to the atmosphere. Water is the single most limiting essential resource for tree survival and growth. Water shortages severely damage young and old trees alike, and set-up healthy trees for other problems. Drought conditions can lead to tree decline, pest problems, and non-recoverable damage. Supplemental watering can greatly assist in maintaining tree health during droughts - both during the growing season or during the dormant season.
- Vegetation Control
-
Regardless of the species of Christmas trees grown or the type of vegetation surrounding them, vegetation (brush, grass, weeds) control is the most important cultural practice during a plantation�s life. Control will ensure high quality tree production at a minimum cost.

The balsam woolly adelgid (Adelges piceae) (BWA), previously called the balsam woolly aphid, is a tiny, soft bodied insect which appears as white, woolly spots on Fraser fir.
- Sphaeropsis Shoot Blight
-
Non-native, exotic pine species growing outside their natural range are especially vulnerable to attack. Other predisposing environmental factors include poor site, drought, hail or snow damage, compacted soils, excessive shading, insect activity or other mechanical wounding.

Construction Tolerance and Comments Regarding Trees Commonly Found in Ohio
- Large Trees For North Carolina
-
Large trees are dominant features in the landscape. Many plans rely on trees for several design functions: to provide background, enclosure, define spaces, help reduce noise and unsightly views. Trees also provide needed shade, channel breezes, and break forceful winds. They also help the environment by filtering pollutants and exchanging oxygen for carbon dioxide.

This publication discusses establishing riparian buffers and plant selection.
- Building Homes for Squirrels
-
When natural cavities are hard to find, squirrels will readily use man-made dens--sometimes they even prefer them. This preference may be because the dens are dry and protect the squirrels from most of their enemies.
