Carolyn Pond Dry-up 2010

The chart to the left shows a distinct change in Carolyn Pond populations even before the pond dried up. The charts below attempts to find out how the dryup changed the populations in the pond by comparing it to the populations in Fairmont Pond, a nearby pond that kept most of its water over the same time period.

The chart above shows a similarity in the most common species in the two ponds before the Carolyn Pond dryup. Fairmonts populations changed in the entire period covered here. Damselflies seemed to be most affected during this time in Carolyn Pond possibly due to the dryup of this pond. The other changes in Carolyn Pond seem to be due to differences in other environmental factors in the two ponds. To come to any more conclusions awaits repeated and other studies in our ponds
