On Saturday April 9th, graduate students from SNRE assisted the Nature Conservancy in removing invasive species at the Patagonia-Sonoita Creek Preserve.  Students spent three hours removing Tree of Heaven plants in an attempt to promote the establishment of native seedlings such as Black Walnut.  In addition to this, students surveyed the area along Sonoita Creek identifying invasive Pampas Grass and removing one large plant.  SNRE graduate students hope to provide more of these opportunities for students in the future to engage with each other and the community.
