In 1990, Calvert County Department of Planning and Zoning contracted with John Hench, PhD. to study the natural resources and habitat of the Flag Ponds area. The objective of the study was to give a general picture of the Flag Ponds habitat by the development of maps as well as a permanent survey of the plants of thirty randomly selected sites based on a 500-foot grid interval.
The objective of the 2016 volunteer conducted survey, initiated by Karyn Molines, Calvert County Natural Resources Division Chief, was much less extensive. The goal was to simply find the original thirty sites and to do a cursory evaluation of the change or lack of change in the habitats.
Calvert Stewards Mary and Gordon Burton worked for 3 years researching the project, surveying plots, and summarizing the findings. Without their dedication, this project would not have been completed.
