Module 1: What are the top 10 ways trees become hazardous?

It seems everyone today has a “TOP TEN” list for one thing or another. So we thought we would come up with the Top 10 Ways Trees Become Hazardous.  Now we aren’t advocating that you would intentionally allow your trees to become hazardous, but through years of experience in the fields of urban forestry and arboriculture, we have witnessed some common trends in the types of tree decline and death that occurs in the landscape. So here is a list of what NOT to do when it comes to tree planting and care.

How Trees Become Hazardous: Number 10 - Lack of Knowledge of Trees
Most people don’t know as much about trees as they think they do. There are still a lot of myths out there about trees, such as how deep root systems go (not very), whether you should use wound paint after pruning (no), or that you should make pruning cuts flush with the trunk of the tree (NOT!). The fact that you are completing this module shows that you’re taking the initiative to learn more about the trees in your yard. Congratulations!

How Trees Become Hazardous: Number 9 - Lack of Concern for Trees
Some people don’t care about trees. They think trees get in the way. They don’t realize that we couldn’t even live on this planet if it weren’t for trees. People that lack concern for trees often make mistakes around them that contributes to the decline or death of trees. Take the picture at right for example. See that new sidewalk?  Guess what probably happened to the tree roots when the new sidewalk was put it.  If people who work around trees aren't concerned about the impacts of their work, this is what can happen.  If you appreciate the benefits we get from trees, spread the word to others!

How Trees Become Hazardous: Number 8 - Lack of Space for Trees
When someone plants a tree, they often think of the tree in terms of the size it is at that time rather than how big the tree will be when it matures. Very often we find the wrong tree planted in the wrong place, so the tree doesn’t have enough room to grow properly.  This competition for space often results in a tree that comes in conflict with sidewalks, utility lines, buildings, or other structures. And the tree often loses.  This tree at left is a good example; shoe-horned in between a house and a garage.  When planting a tree, think ahead!
