The ICPS welcomes Carson Trexler to the Board of Directors

The ICPS Board recently welcomed Carson Trexler as the Director for Conservation and Research.  Brent Jones became the Director of ICPS Conferences and Membership Development.

Carson has been a member of the ICPS since 2007. His relationship with CPs focuses on the ornamental horticulture of Sarracenia. Carson has worked at Sarracenia Northwest, a Carnivorous Plant nursery, for 3 years, and attends Oregon State University, pursuing a degree in Horticulture. He lives in Portland, Oregon, USA, where he enjoys being an active part of the local CP community. Carson is ambitious to develop this position into an effective, modern office for the purpose of CP research and public awareness about conservation. In particular, he is keen to engage the ICPS membership, by showcasing our work through CPN and other outlets. Carson will focus on expanding the ICPS’s involvement in conservation projects in the United States and Internationally, and working closely with existing conservation involvements.
