Abstract

Corema conradii (broom-crowberry, Ericaceae) is a rare dioecious shrub that reaches the southern extent of its range in New Jersey. A hot fire burned through one of the most extensive New Jersey populations of this state-endangered species during the summer of 2001, resulting in mortality of nearly all plants in the burned areas. Significant seedling recruitment occurred in the fall of 2002, followed by an even greater seedling emergence the following year. Fire is known to be an important stimulus for seed germination in this species, and fire events are an important component of the life cycle. We report data on seedling emergence as well as present ecological and biological observations of Corema conradii in the unusual coremal habitat of the New Jersey Pine Barrens, and suggest a life cycle model for this understudied species.
