 The rings of a tree tell the story of time. A wide ring indicates good growing conditions, likely caused by plentiful rain. A thin ring shows the effect of drought. Lack of water causes the tree to slow its growth and compensate for reduced rainfall. Drought brings stress to trees. It means reduced growth and decreased resistance to insects and disease. Young seedlings and saplings and old trees are more vulnerable to drought. Drought also increases the risk of wildfire. Dry plant material becomes fuel for a fire. When humidity drops and temperatures climb, a spark from a car or a bolt of lightning can cause a raging wildfire. Wildlife also suffer the effects of a drought. Food and water is in short supply, so overgrazing preferred plants can reduce competition for weeds. Drought will come, as will floods. Check with your county extension office to prepare for both.
