A non-native grass species, Puccinellia Maritima, has been identified in the Novato Baylands, California, marking its first appearance in the North Bay. Experts warn it could threaten native plants and wildlife, prompting immediate tracking and potential eradication efforts.
- 01Puccinellia Maritima, native to Western Europe, is the first invasive species discovered in the North Bay's Novato Baylands.
- 02The invasive grass could outcompete native plants like pickleweed, which are crucial for local wildlife, including the Ridgway's rail and salt marsh harvest mouse.
- 03Tracking the invasion involves mapping its density and location using technology like ArcGIS.
- 04Over 90% of San Francisco Bay's marshes have been lost in the last century, making the preservation of existing marshes critical.
- 05Eradication efforts may include herbicides and hand removal to maintain the ecological balance of the tidal marsh.

In Novato Baylands, California, a non-native grass known as Puccinellia Maritima has been discovered, marking its first occurrence in the North Bay. Leia Giambastiani, a restoration manager with Point Blue Conservation Science, flagged the invasive species during a routine check. The plant poses a threat to local ecosystems, potentially crowding out vital native species such as pickleweed, which supports various wildlife, including the Ridgway's rail and the salt marsh harvest mouse. Alejandro Rosales collaborates with Giambastiani to monitor the invasion's extent using mapping technology. The discovery comes as the Novato Baylands restoration project faces challenges, having already lost over 90% of its marshes in the past century. Experts suggest that controlling the invasive grass may require a combination of herbicides and manual removal. The ongoing efforts to manage other invasive species, such as Spartina, demonstrate the expertise available to tackle this ecological challenge.
