The Vegetation

After years of abandonment without regular land maintenance, invasive and exotic species proliferated on Hassel Island, threatening the native vegetation.  The NPS and the St. Thomas Historical Trust are working hard to eliminate the invasive species, cultivate native plants, and restore balance to Hassel Island’s ecosystem.
