Learn to tell apart the major broadleaf trees of western Oregon. Limbs will be partly bare, so we can see the branch structure; but there will be some leaves remaining, to learn by the foliage. Don't be fooled! Our native trees are there, but some "guest" trees have crept in over the years from the neighborhoods. From the parking area on Milwaukie Avenue we'll walk downhill into the quiet retreat of Portland's urban wildlife refuge. We will be able to see all the trees within a mile round trip, entirely from paved paths, but you can explore further if you wish. Held rain or shine.
