With
the changing climate, are you seeing new species moving into Iowa?
Not with any certainty. In my research I have
documented new plant species for Iowa and range expansion northward, but it was
due to seeding in a reconstruction. There has been so much moving around of
species by people planting seeds of species outside of their range that it is
impossible to attribute changes in range to natural migration. One thing that
does seem to be sure is that more and more nonnative and invasive plant species
are being observed in Iowa (meaning higher abundances). That may be in part an
indirect result of climate change, because if native species are being stressed
by climate change, this could be helping to open the door for nonnative species
already in the state to expand.
Besides
teaching, what other projects are you involved with right now?
Research that is aimed at investigating the
effects of goat browsing on savanna restoration (do goats make good partners in
conservation and restoration work?). Similarly two projects are assessing the
effects of cattle grazing on prairie (both reconstructed and native remnant).
Do cattle make a good surrogate for bison? Another project is providing
ecological data relevant to building 25 miles of new trail at Whiterock
Conservancy. One part of this project involves setting up long-term monitoring
plots to assess the impacts of trail use by horses and mountain bikers on
plants, small mammals, butterflies, and ground-dwelling invertebrates. I am
also finishing up a natural resource inventory of all the land in the Des
Moines park system. This is mostly focused on mapping and delineating the plant
communities present and describing their plant species composition, their
structure, and their successional status.
How do you balance your teaching and writing with your hands-on
research and fieldwork?
I certainly have to prioritize tasks. And that is
often determined in part by the amount of funding provided. Somehow most tasks
get done in a timely manner, albeit with long work days and not very many days
off. My research agenda has been expanding quite a bit over the last few years,
which has put a damper on some other pocket guide projects (ferns and sedges).
However, I do anticipate making significant progress on them next field season.
Unfortunately some of the things I most would like to work on – Field Guide to
the Loess Hills and a revision of the Checklist of Iowa Vascular Plants – seem
to constantly be out of reach due to the lack of funding they need in order to
raise their priority.
