The decline in trees has certainly been noticeable in Atlanta, a metro area where, according to a
BBC story, 154,000 hectares (380,000) acres of trees were lost between 1973 and 1992, a rate of 22 hectares (55 acres) per day. Since 1992 many more trees have been lost. Every week another mini-forest is mowed down for new residential, business, or road development.
So we end up with a worsening cycle of summer drought and pollution, more air conditioning, more cars and SUVs, and all the attendant health and quality-of-life issues.
Is it a coincidence that Atlantans now suffer through some of the most
nightmarish commutes in the country?
Fortunately, folks like the USDA
Center for Urban Forest Research are working to protect urban trees and encourage tree planting and care.
And many urban areas of all sizes have ordinances in place to protect trees. The
Urban Forestry South web site has info about these in the southeastern U.S. I'm sure there are similar resources for other areas.
Legislative solutions don't always work, though. The developer who put a new house on a vacant lot in my neighborhood had to plant some new trees with trunks a couple of inches in diamater to replace the large old trees he removed (or face fines of several hundred dollars). After a year in the house, the new homeowners cut down the replacement trees, which were too small to fall under the county's legal protection. So much for the tree ordinance.
There are still a lot of trees in my city, and I'm encouraged to see new ones being planted all the time. But it's an ongoing fight to ensure the long-term vitality of trees, and thence our urban environment.
Thanks, Barrett808, for reminding me how important this is. Soon as I can, I'm going to
climb a tree.
