Anyone who has a home with trees around it will someday need to remove dead or dying limbs and trees. The best managed landscaping requires trees to be pruned or removed as they grow. In addition, storms often create dangerous situations as limbs and trees are broken or bent over. I remember living on Lake Martin in Alabama during Hurricane Opel. The storm hit at night and we sat in the basement listening to all the commotion and guessing what was happening to our home. Occasionally, I would go up to the main floor with a flash light (power was toast) and peer out the windows trying to assess the damage. One time I reported to my family that the porch roof was gone. The porch faced the lake and the direction of the wind. It had rained all day before the hurricane winds hit causing the soil around the trees that separated our home from the water to soften up. At day light we found all the lakeside trees pushed over onto our roof.

  • Advise and develop protocols for assessments of power line tree exposure and mitigation
  • Advise on least cost vegetation management by synchronizing economics and ecology
  • Advise on impacts of vegetation management program alternatives, modifications

Abstract — Severe weather events such as ice and tropical storms routinely cause extensive damage to electrical distribution systems. Much of the damage and service loss can be attributed to trees. Events where service restoration spans days or weeks are generally closely examined through regulator directed hearings. Even when no specific actions are subsequently

Abstract - For power transmission systems compliant with safety codes and reliability standards there remains a risk of tree-caused interruptions from the in-fall of trees from outside the right-of-way. This paper reports on the quantification of tree exposure outside National Grid’s transmission corridors and examines the variables impacting the risk of a line contact by trees

  • 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).
