Project: Ecosystem Engineering Impacts of Water Primrose in the Delta

Description: Prior research has shown that marshes are vulnerable to water primrose impacts which would negatively affect emergent macrophytes that support the Delta’s native fish and wildlife species and are important contributors to processes of vertical accretion. Over ~700 acres of marsh were lost to water primrose invasion in the Delta between 2014-2016. Funding for this project will be used for a study that addresses the scientific underpinnings of how water primrose invades and overtakes marsh as well as the factors that make marshes vulnerable to takeover in the first place.

Reference Number: 3600BQ2096002

Implemented By: Regents of the University of California

Objective: By studying the plant traits of water primrose, this project will determine the likely cause of marsh loss and learn about the process of terrestrial water primrose invasion. This will inform the conceptual model of invasive aquatic vegetation invasion in the Delta and will enable researchers to identify and map the marshes that are most vulnerable to takeover by water primrose, which will help to inform future restoration efforts.
