Aquatic Vegetation Project Work Team

The Aquatic Vegetation Project Work Team provides a forum for examination of the ecological effects of aquatic vegetation and treatment efforts, discussion and collaboration among scientists and managers working on aquatic vegetation ecology and control of invasive plants. The PWT formed in 2016 out of a need for coordination among new science projects and a recognition of the importance for increased and more consistent monitoring efforts. In addition to scientific discussion, this group has published a monitoring framework to track trends in vegetation species and coverage, and developed conceptual models of aquatic vegetation ecology in the Delta, published an integrated field dataset of submerged vegetation communities in the Delta and conducted several aquatic vegetation identification workshops with live specimens for the Delta research and monitoring community.

Objectives

• Provide a forum where researchers can discuss research and monitoring activities on Delta aquatic macrophytes
• Provide guidance and evaluation of aquatic vegetation management efforts to improve aquatic habitat
• Support the development of detailed work plans for proposed new studies
• Coordinate with the Tidal Wetland Monitoring PWT to facilitate information sharing and communication among other groups also working on invasive macrophytes in the Delta
