1.	Excessive crowding of trees: Will cause them to grow tall and spindly, weaker and less desirable. Remove less vaulable trees to allow the remaining trees to grow properly.
2.	Thick Canopy: Allowing too much wind resistance and excessive weight. Selectively thin out canopy by reducing the weight and allowing wind to pass through will promote a much healthier tree.
3.	Leaning Trees: With surface roots and heavy canopy’s, leaning trees can become an emanate danger to people and property. Lighten up or remove depending on situation.
4.	Boring Insects: Borers are attracted to unhealthy trees, burrowing in and laying eggs inside the trunk. The best defense against these pests is to keep your trees healthy and unstressed.
5.	Trees growing too close to a structure: This can cause damage to roofs and foundations. To alleviate possible damage, trim back limbs from over roof and if necessary cut roots growing toward the structure.
6.	Non Native/ Invasive Trees: These trees rob much needed nutrition from native specimen trees. Remove these trees and give life back to your more valuable trees.
7.	Hardwood Stem Diseases: Such as hispidus canker, hypoxylon cankers, root rot, etc. Remove  diseased trees or treat if possible.
8.	Tree trimming by unqualified personal: This results in excessive stress on trees and can sometimes caused unrepairable damage. Always rely on a ISA Certified Arborist before this happens, he or she can offer sololutions to correct the damage. Check a company's qualifications through ISA-arbor.com , and the Better Business Bureau before making a regretable decision.
9.	Cracks between dominate and co-dominate stems: These cracks can be caused by too much weight and inclement weather conditions. Lighten up each stem and possibly install cables for support.
10.	Vines or Ivy Covering Canopy: Vines add excessive weight and wind resistance. Cut or remove ivy or vines to reduce weight and keep your trees healthy.
