2. Research

We are conducting studies on the genetics, biochemistry, ecology, and population biology of the pitcher plant genus Sarracenia, long leaf pine and white cedar. An understanding of these factors is central to effectively managing, preserving, and restoring remaining sites.

Papers marked with the globe are available online.
