While out in the field at Blackwater, we were looking for herbivory amongst our plots which consisted of non-vegetated and vegetated plots. These silver metal pieces were actually turned into homemade animal track plates using ethanol, mineral oil, and graphite powder. Radha, Taylor, Keryn, and I mixed the ethanol, oil, and graphite powder to create homemade ink. The ink was later spread across the tract plates and, these were later used in the field to see if animal activity was present.

“Why is it so important that you find the elevation of the lands in such precise measurements?”
In the beginning of our research project, we already started knowing that there was a high marsh elevation, a mid elevation, and a low elevation due to the changes in plant species and habitat, but the land is so flat that it is difficult to perceive these small differences in elevation. Under the supervision of Dr. Keryn Gedan I learned that although we can visually see the physical change in ecotone elevation, this proposal needs to be backed by actual numerical values. While using the Trimble RTK we acknowledged that on the Control Sites some of the numerical values did in fact correspond with what we expected but, in other areas where variation looked significant different the data showed the numerical values were less dramatic in change.
