Public Comments Opportunity Extended:

Delta ISB Review of Food Webs in the Delta

As a reminder, the Delta Independent Science Board is seeking input on its draft review, “Exploring scientific and management implications of upper trophic level food webs in the Delta.” The draft was based on a review of the literature on the subject, public comments on the prospectus and at Delta ISB meetings, and a focused two-day workshop. The goal of this review is to provide information that would help organizations, including state and federal agencies, assess how to better incorporate and advance food web knowledge in managing the Sacramento-San Joaquin Delta’s ecosystems and to identify what tools are available or should be developed.

Public comments were originally due on June 7, but the due date has been extended. Please provide public comments by 11:59 PM on June 14, 2024, via email to [email protected], or by mail to the address below.

READ THE DRAFT

What are food webs?

Food webs describe the trophic (feeding) relationships and flows of energy and nutrients among species in an ecosystem. Upper trophic levels, the focus of this review, include fish, particularly those (e.g., salmon) being actively managed in the ecosystem. Predicting the impacts of habitat restoration, fisheries, changes in environmental drivers (e.g., climate change) and the bioaccumulation of contaminants on species or the ecosystem requires an understanding of food web processes.

Presentations on how understanding these dynamics could help inform management occurred at the Delta ISB’s two-day workshop in November 2023. Recordings for both days can be found on Cal-Span (day 1 recording and day 2 recording).

About the Delta ISB

The Delta ISB advises the Delta Stewardship Council and provides oversight of the scientific research, monitoring, and assessment programs in the Delta through periodic reviews.
