Ulmus americana

American elm used to be one of our most cherished street trees. Dutch elm disease has ravaged our elm-tree-lined streets, but research may provide a remedy someday.
Birch/balsam fir
(204k)
This is a birch and balsam fir stand in the Superior National Forest, overlooking Grand Marais, MN.
Birch/balsam fir
(167k)
This is another view of the same stand as above. We'll be using this site for research into how to restore white pine to habitats such as this one, where it once was common.
Quercus macrocarpa (244k)
This is a large branch of a bur oak. Most tree species don't support lateral branches of this size, but it is these branches that give the mighty bur oak its unique character.
Lake Michigan
(84k)
This picture was taken near Petosky, MI, at sunset, looking out over Lake Michigan ("Lake Michigan steams like a young man's dreams," in a popular Gordon Lightfoot song.
Ice storm aftermath
(121k)
Looks cold, doesn't it? It was cold. This picture was taken after a freezing rain episode in the fall of 1995.
Ice-covered trees
(186k)
Another group of ice-covered trees, these photographed in the winter of 1996.
Sylvania wilderness
(147k)
The Silvania wilderness area of the Ottowa National Forest is like a "mini boundary waters," with its chain of lakes. White pine like these once dominated the entire northern Lake States area.
Pseudotsuga menziesii
(71k)
O.K., this is not a species native to our area. These are the developing cones of Douglas-fir, which is a species that occurs west of the Rocky Mountains.
