Delta Interagency Invasive Species
Coordination (DIISC) Team Activities and Symposium

The DIISC Team has implemented or sponsored multiple projects to strengthen communication and collaboration among organizations involved in invasive species management in the Delta.

Delta Invasive Species Symposium 

Since 2015, the DIISC Team has organized a biennial Delta Invasive Species Symposium.

2021: Early Detection and Rapid Response
December 15, 2021 – Zoom Virtual Event

Registration is now open for the fourth Delta Invasive Species Symposium!  

Register via Zoom: 

The biennial Symposium is a forum for Delta managers, researchers, and decision-makers to meet, share and synthesize information, and communicate best practices and lessons learned. This year’s Symposium will focus on early detection and rapid response (EDRR) to invasive species. The virtual event will take place on December 15, 2021, from 9:00 a.m. thru 2:30 p.m. 

The Symposium will highlight EDRR lessons learned, current EDRR efforts across the Delta and beyond, and future challenges and solutions for EDRR work. The Symposium will consist of invited talks, a panel discussion, and an opportunity for participants to provide feedback on the draft Delta EDRR Framework being developed by the Delta Interagency Invasive Species Coordination (DIISC) Team. The Delta Interagency Invasive Species Coordination (DIISC) Team plans and facilitates the biennial Symposium.   

Register here and watch our website where the agenda and other details will be posted in advance of the Symposium. 

2019: Remote Sensing Applications for Management
August 29, 2019 at UC Davis

Presentations explored remote sensing tools and applications for invasive species management in the Delta available today and opportunities for the future. The symposium was sponsored by the DIISC Team, Delta Stewardship Council’s Delta Science Program, and UC Davis.

2017: Tools and Actions to Meet Current Needs and Prepare for Future Challenges
August 29, 2017 at UC Davis

Presentations explored tools and actions being developed to meet today’s management needs as well as to prepare for future challenges. The seminar also explored our understanding of how habitats can be managed to encourage native and deter invasive species, and how social science can be better integrated into invasive species management. The symposium was co-sponsored by the DIISC Team, Delta Stewardship Council’s Delta Science Program, and UC Davis.  

2015: Invasive Aquatic Vegetation

DIISC Team members and speakers from the 2015 symposium co-authored a review article that was published in San Francisco Estuary & Watershed Science in December 2017.

Investigations of Restoration Techniques That Limit Invasion of Tidal Wetlands

In 2017, UC Davis received $107,655 from the Sacramento-San Joaquin Delta Conservancy’s Proposition 1 Grant Program to investigate restoration techniques to limit invasion of tidal wetlands. The project identifies improved methods for tidal wetland revegetation that reduce invasion by non-native plants at Dutch Slough. The DIISC Team identified this project as a research priority in 2015 and participated in the grant proposal development.
