Not all trees are created — or planted — equal.

In D.C., and in lots of cities, certain kinds of trees tend to be particularly popular — think American elms, or Bradford pear trees. But sometimes those trees aren’t good barriers to the exhaust and road salt and other pollution that come along with life in an urban area. And those trees also aren’t always great at promoting biodiversity in the urban ecosystem as a whole.

This week the non-profit Casey Trees hosted an entire symposium on this very issue. Richard Olsen, a research geneticist at the National Arboretum was one expert in attendance.

Olsen says there are a few key lessons to follow when it comes to creating a healthy urban tree canopy, and spotlights some of his favorite species.
