Casey Trees used data from DDOT’s Urban Forestry Administration to create a great interactive map of street trees:
Blue dots show maple trees, red dots are oak, pink elm, green sycamore, and yellow dots show all other trees.
Erik noted this in a Breakfast Links recently, but it’s interesting enough to show in more detail. It’s fascinating to see how most streets have one or two types of trees. In many neighborhoods the oaks line more of the major streets and maples smaller ones, though in some places, like Georgetown, there are many trees but almost no oaks.
Clicking on a tree also shows its size. A future improvement to the map might be to show larger dots for larger trees, to help people visualize the overall tree cover.
