On
Saturday, October 25, I took our three botany majors and one prospective botany
major to a nearby Nature Conservancy preserve, the Pontotoc Ridge preserve, for
its annual fall tour. First, notice that we have at least three botany majors,
in a university of about 4000 students. And they seemed to really enjoy
visiting this natural area.
Part
of the forest area is near a creek. The major tree species appeared to be red
oak (Quercus rubra; Fagaceae). But the largest trees, though fewer in
number, were bur oaks (Quercus
macrocarpa; Fagaceae), some of which were enormous, and into which one of
our brave botany majors climbed.
The
bois-d’arc trees (Maclura pomifera;
Moraceae) were all dead, at least the ones we saw. This could be due to the
normal successional process, which began when the bur oaks were the only trees
in the field, and in whose partial shade the red oaks grew up and shaded out
the bois-d’arcs.
We
also visited a limestone cave, in the runoff of which can be found unique taxa
of invertebrates. This year, however, due to the ongoing drought, there was no
water. There has been plenty of rain this year in Oklahoma, but in scattered
rainfall events. The topsoil was moist; grass in yards and hay in fields grew
luxuriously. But the groundwater was not recharged. While the summer was not
very hot, the autumn has been unusually warm: it was 90 degrees on October 25.
October
25, 2014, also happened to be the twentieth year of the Pontotoc Ridge
preserve, and the dedication of the new building with facilities, small but
good, for visiting researchers to live. A large part of the success of this
Nature Conservancy effort has been due to Jona Tucker, the director, who
graduated from our university with a botany degree in 2001.
I
wanted my students to see that botany majors can go into numerous lines of
work, from lab research to conservation, and to see that botany is alive and
well.
