Is My Tree Dying?
tree live longer.
I will add that county agents do look at trees and I do often, but agents are not certified to do hazard assessments of trees like an arborist would do if hired.
When evaluating a tree, start at the base of the tree and look at the root system and the root flare of the trunk. Do you see fungal bodies such as mushrooms or conks growing on the ground around the root system? If you seed these fungal bodies, this is a sign of severe or advanced rot in the trunk or root system of the tree. Root decay issues cannot be reversed or fixed so this will cause the tree to be less stable. Root decay is a sign that the tree is in a death spiral. If the root system is failing, the tree will decline and the tree can fall. You also need to look at the trunk flare at the tree base. A healthy tree will be wider at the base where the tree meets the ground. Inspect the flare areas for signs of injury. This is where you can see weed eater or lawnmower damage or damage where a person backed a car into the tree. Injury can reduce the flow of water and nutrients, less vigor and can lead to structure issues.
Construction damage can also be a problem with trunk flare areas and also issue when roots are covered with soil. Most roots are in the top 12-18 inches of soil so they can be damaged by all kinds of construction from septic lines, sidewalk work or soil grading in the root zone. Remember to also look at the actual trunk of the tree. Look again for fungi growth which is a sign of internal rot. Look for areas of bark damage or signs of disease. Look for cankers on the stem or branches or even physical damage in the bark. Bark damage can slow nutrient transportation and can result in dieback of branches and limbs.
Finally, look at the branches and leaves. Do the leaves look healthy? Do you see leaf spotting? Do you see insect or disease damage? Do the leaves look of normal size and color? Leaf injury can be the result of many things such as drought or insect damage for example. Leaf issues could be temporary. Early leaf loss may be a sign of branch dieback and a more serious issue at the same time early leaf loss could be a temporary stress caused by drought or disease that does not cause long term issues. You can look for dieback which are defoliated limbs or twigs seen out of the tree canopy. Dieback can be a sign of other issues such as internal decay.
