Portland neighborhoods such as Northeast Knott, shown here at 42nd Avenue, are among areas with the highest percentage of tree-canopy cover. Currently, 26 percent of the city is under the tree canopy, and the goal is to reach 33 percent. Trees improve neighborhood livability, in part by shading buildings and potentially reducing demand for heating and air conditioning.
