Interpretation of historic and current aerial photography is an important skill for wetland ecologists of all disciplines because it helps tell the story of land use over time. Whether you are conducting a wetland delineation or planning for habitat restoration, review of historic aerial imagery can reveal land use changes that help you better understand soil structure, hydrology, and vegetative patterns. In this session, I will discuss potential sources of aerial imagery, acceptable methods for interpretation, and requirements for wetland delineations in Wisconsin. We will also review case studies and collectively evaluate various wetness signatures to illustrate the intricacies of this practice.
