That's why Mayor Rawlings-Blake has continued the pledge Martin O'Malley made when he was mayor: to double the city's tree canopy, by 2037, to 40 percent coverage. Today, our tree cover is estimated at 27 percent, which means we need to accelerate our efforts further. The Department of Recreation and Parks' Urban Forestry Division leads a committed group of government and community partners through the TreeBaltimore coalition to prioritize our tree planting opportunities and plant thousands of trees each year. Together, we organize volunteers; provide technical assistance, training and grants to tree planters; and coordinate research, marketing and fundraising activities. Last year, we increased the number of trees planted by more than 10 percent, from 7,400 in 2011 to 8,200 in 2012.
