Photographic History of our Tree Farm on a Phosphate Mining Clay Settling Pond Area Common Purpose Institute University of Florida/IFAS October, 2003

Prior to 1940’s, Site was a Cypress Forest.

Phosphate Mining Clay Settling Pond Site created in the 1940’s. Heavy clay soils at our Site reach depths of 30 to 60 feet.

As Clay Settling Pond De-watered (over 10 to 15 years), Site was invaded by Cogongrass.
