Estimates show that Oakland's urban forest includes over 200,000 trees. Tree Services manages all trees in sidewalks/streets, medians, City parks, and within the City's right of way. A 2015 tree canopy survey estimated that trees cover approximately 24.7% of Oakland. This puts Oakland in about the mid-range of cities in the Bay Area for the size of its urban forest. An inventory of street and park trees is currently underway to count Oakland’s trees. The results will help the City plan for the future of Oakland’s urban forest.
City trees provide many environmental and health benefits. Trees absorb carbon, remove pollution from the air, reduce flooding during storms, prevent erosion, and provide wildlife habitat. Studies show that trees also reduce stress and shorten recovery periods after surgery. The presence of street trees in a neighborhood slows traffic, reduces crime, and encourages people to spend time outside.
The healthier our trees are, the better they perform. Tree maintenance is necessary to ensure proper growth and stability for trees to provide these benefits.
