The Patuxent River, considered “Maryland’s River”, is the longest river entirely in the state of Maryland. Home to over 100 species of fish and a staggering variety of resident and migratory birds, the Patuxent River is a jewel of the Maryland natural world. Archaeological artifacts dating back to 7,205 B.C. suggests the River has been an essential lifeline for humans for thousands of years.

The Patuxent River Conference (PAXCON) is the premier forum uniting scientists, environmental educators, natural resource managers, and anyone passionate about the health and future of the Patuxent River. To know and understand the Patuxent River is to take one more step towards its protection.

You must register in order to receive details on how to join the webinar.
