In the post below I mentioned the danger of tree limbs which fall. Here is an example from the wooded area on the west end of our campus near our border with Fontbonne University.
These fell at various time this winter from trees that have tops that now look like this:
Then another spot in the same area
You really need to be watchful while in an area with lots of trees. I walk Ferdie back in this area a lot and one afternoon the wind picked up and it got very dark and all those trees were bending. All I wanted to do was get out of there. Several years ago the Clayton board of aldermen were discussing the possibility of a new tree ordinance. The idea was to fine residents if they took down a tree on their property whether to build a deck or pool or just get sunlight into the yard. The fine was to be based on the size of the tree and could have gone up to a couple thousand dollars. City officials wanted a big tree canopy in the city. I spoke against this ordinance at the meeting in large part because if you look at Clayton from up high, like from our campus tower, you'll see nothing but trees. And, there comes a point when too many trees compete with each other for light and moisture. Nothing much will grow underneath them except vines. When they lack light and moisture they weaken and we then have the problem of bad trees.
The ordinance was tabled that night and hasn't returned that I am aware of.
