B'More Green: City residents get free and cheap trees - An environmental blog for everyday living - baltimoresun.com:
Baltimore is endeavoring to double its tree canopy from 20 percent to 40 percent during the next three decades and is encouraging homeowners to get planting by offering free and discounted trees.
The city effort is called TreeBaltimore, and officials say it aims to add to the urban forest that does a number of things: provides shade, beautifies neighborhoods, cleans air and water, offers and home to birds and other animals, increases property values and removes carbon from the atmosphere that contributes to global warming.
The push is a mayoral initiative that began in 2007. The city settled on the 40 percent goal, but discovered that about 85 percent of the available planting space, i.e. grass, was on private property, according to Anne Draddy, who runs the city program. So, they began hitting up residents to do some planting and caring for trees.
