As with many forests around the world, a forest stand at Fowler Park in Indiana is declining. The county parks personnel have noted that a variety of tree genera are declining and dying on a campground site in the county park. We know about the presence of Emerald Ash Borer (EAB), but species from four genera are declining so the sole cause is not EAB. Decline could be due to climate change (warming temperatures), soil compaction at the local site, herbicide use at the site, or other mitigating factors such as a variety of insects attaching each genera of tree. We have sampled all of the trees in the effected campground and surrounding control sites. We use ring-width characteristics, timing of decline, and quantitative wood anatomy to determine the cause for decline in this particular forest. We have identified the specific effect of EAB in ash trees on the site, but also documented a marked decline in black locust and other species.
