Introduction to Wetland Determination - 2025


In this course you will gain a basic understanding of how to properly recognize wetlands in Pennsylvania and at the conclusion you will be able to identify and evaluate the three components that make up a wetland; hydrology, hydrophytic vegetation and hydric soil. This course was designed specifically to meet DEP’s regulatory programs related to wetland identification and the 1987 Army Corps of Engineers Wetland Delineation Manual and the associated Regional Supplements. 


DISCLAIMER: This training is meant to be foundational educational information on wetland identification. This is not a substitute for field experience. Completion of these online lessons alone do not provide adequate knowledge and experience to delineate wetlands.
