Wounding - non-human - Trees are often wounded by agents other than humans. Many trees in south Florida were injured severely by hurricane Andrew several years ago. After storm injury, work must be done first to reduce the risk of fractures that could cause problems for property and people. Next, the trees should be pruned for health. This means cutting off torn roots and removing long, injured branches to avoid sprouting that could lead to fractures. In cold climates, winter ice injury can cause serious injuries. The same three part program given for hurricane injury should be done for ice-injured trees. In forests, the ice-injured trees add much needed carbon as cellulose for soil organisms. Forest practices during the last several decades have removed so much cellulose that Tree Biologist believe soil organisms are starving.
