  • 8/2/2012 · Plants & Trees
    The number of storms in recent years increases the need for better tree and landscape decisions for property owners. Research regarding landscape damages for different storm intensities, what plants get knocked down by winds more often, and priorities for landscape restoration have been intensified by many southern state universities' forestry and horticultural departments.

    Trees and landscapes have been valued since humans were given gardens for food and enjoyment. Once people determined how to harvest seeds, how to plant gardens and landscapes, and how to relocate trees and plants, then decisions about what to use and what not to use began to set values for plants. It is this author's opinion that these practices logically date back to the beginning of history.

    3/7/2012 · Plants & Trees
    The value of a tree can only be determined if we agree. Any value given, whether by a layperson or a professional, is real when another person involved in the process agrees to that value. The value used in the final decision can also be a different value from the one determined by the experts who worked on it (especially when the experts worked on different sides of a valuation case).

    VIDEO: What Is A Consulting Arborist?
    5/1/2017 · Plants & Trees
    Whether the companies planting these trees are planting them incorrectly out of ignorance or in pursuit of maximizing profits; get in, get out, get to the next job, I do not know. In either case, it behooves a homeowner or property manager to do their due diligence and educate themselves on proper tree planting technique so that they will recognize when they are receiving a quality service and when they are throwing their money down the drain.

    2/28/2017 · Plants & Trees
    As defined in the tree care industry, a "Hazard Tree" is a tree that poses a level of risk to people or property that exceeds the risk tolerance of the property owner or manger. This means that a tree that may be considered a hazard to one property owner may not be considered to be a hazard by another property owner. Thus, "hazard tree" is a somewhat subjective concept, used when making tree risk management decisions on a particular property, and is not a description of the inherent level of risk actually posed by a particular tree. In the tree care industry the term "hazard tree" is generally reserved to describe a tree that requires immediate removal, or other mitigating actions, to reduce the level of risk posed.

    There are many terms in use describing different types of tree care professionals and this can cause considerable confusion for a homeowner or property manager who requires a tree care provider. The information below will hopefully provide some clarity on the topic.
