Added: November 05, 2008The success of tree plantings in communities and yards is dependent upon many features of species, site, and planting procedure. One component of site which directly affects new tree success, continued low maintenance growth, and relatively long life span is the open soil surface area and volume of soil colonized by roots. Selecting new planting sites for the availability of adequate resources, now and into the future, as trees expand their resources will maximize the chances of producing a great, long-lived tree.

Added: October 25, 2008All that can be seen of a growing tree is the outside, but the inside is what determines its value as raw material for wood products. A pine tree grows noticeably taller and bigger around each year, and it adds new branches and new needles. Under normal growing conditions, it also adds a new layer of wood along its entire length in the form of a continuous sheath under the bark. Annual overlapping sheaths are what form the main stem and the branches.
- Forestry BMP Implementation Costs for Virginia
-
Forestry Best Management Practices (BMPs) are operational techniques used to protect water quality during timber harvesting operations. The implementation cost of BMPs is important to loggers, forest landowners, and the forest industry. This study provides an estimate of BMP implementation cost on a per harvested acre basis for the coastal plain, Piedmont, and mountains of Virginia.
- 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.
- Citrus Tree Stresses: Effects on Growth and Yield
-
Although Florida is known for its plentiful sunshine and rainfall, commercial citrus can experience stress at certain times of the year whenever growth conditions are not optimal. For example, drought stress can occur whenever soil water is not adequate or whenever the evaporative demand of the air is high. Drought is one of the most formidable stresses. It alters a tree's ability to take up nutrients from soil and changes the way the tree produces roots, shoots, leaves and fruit. To strive for consistently high commercial yields, grove managers must incorporate strategies to minimize the negative effects of drought. The objectives of this document are to: a)Explain how citrus trees respond to changes in availability of water and nutrients; b)Discuss plant-stress situations and their effects on citrus growth and productivity; and c)Discuss the balance between roots and shoots. The target audience for this document dealing with citrus responses to drought conditions includes: Certified Crop Advisers, citrus producers, agrochemical and equipment industry representatives, and other parties interested in citrus management practices.

The decision to protect and preserve trees on a construction site is an important one. Many sites are chosen for residential or business use simply because the site contains a beautiful shade tree or offers a wooded environment. Often the very trees which are highly valued for their contribution to the aesthetic appeal of a site are inadequately protected or cared for during construction

- 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.
