Most people are aware that there is a National Big Tree Registry, celebrating the largest trees of each species in the United States, but fewer are aware that this Registry was started in Maryland, and that Maryland had the first official State Big Tree Registry. Within Maryland some counties have registries and some do not. In this paper we review the current status of the Big Tree registries at the county level. We also present updated records for Wicomico County, including the discovery of four new State Champion trees.[PUBLICATION ABSTRACT]
