This evaluation study was conducted with
the support of Ohio Division of Natural Resources, Division
of Forestry and the cities of Cincinnati, Cleveland, Columbus,
Dublin, Toledo and Wooster as well as Ohio’s investor
owned utilities. One study relates the performance of trees
in almost 100 sites in Ohio over more than 35 years. Photographs
of the sites shortly after planting and in 1997 show the difference
that time can make and are seen in the attached link. Take
a few minutes and make up your own mind.
An article regarding two surveys conducted to identify plants
that Ohio’s urban foresters feel that they will be planting
provides insight into plants that citizens might wish to consider
for their resident or community. Look at the popularity of
ash in the survey taken in 2000. I suspect that this has already
changed in response to Emerald Ash Borer. The next survey
is scheduled for 2005.
A recently established planting in Toledo will evaluate the
tolerance of native and exotic ashes to the emerald ash borer.
Some of the exotic ashes are from the native range of the
emerald ash borer and are expected to show some natural resistance.
Toledo urban forestry personnel are involved in this study.
