The City of Richmond, Virginia's Department of Urban Forestry and Grounds Management has created a great Adopt-A-Tree program that I think could benefit urban areas throughout the country. For a $50 tax-deductible donation you can adopt a tree to be planted by the city. Additionally participants agree to water the tree for the first two years.
Included in the $50 donation is a "Treegator"installed by the contractor. A "Treegator is essentially a drip irrigation system in a bag. Designed specifically for trees, it slowly delivers water directly to a trees' root system over an extended period of time; allowing for deep water saturation with no runoff or evaporation.
I learned about this program after some research into why the city had tagged several trees for removal. In urban areas trees offer shade, food for animals and birds(something severely lacking in many cities) and of course free oxygen. So I had to question why the city would be removing well established trees. I was somewhat relieved to find out the trees were indeed being replaced through the Adopt-A-Tree program.
This is a great program- if your urban leaders are not doing this- I would push for it. If only 10% of the major urban localities across the country would institute a program like this- imagine how many new trees we could plant. Think big...
