The Fight for SBI

Posted by: kristen-boysen | May 27, 2009 | 1 Comment |

Our project makes up only a fraction of the Xantus’s murrelet and Santa Barbara Island restoration projects.  Many of the Channel Islands were disturbed by agriculture and ranching before they became protected. While the feral cats that preyed on the native, nesting seabirds are no longer there,  

Invasive plants, however, still run rampant on the island.  Laurie Harvey, with the help of several NPS volunteers, created a greenhouse on the island where she grows native plants from seeds collected on-site.

The greenhouse even has a solar-powered irrigation system. Because it is on the island, there is no risk of invasive insects or seeds being transported from the mainland (that happened in an early-attempt). Laurie replants huge segments of the island with coreopsis, buckwheat, and other native species- often more than 1,000 seedlings are planted at a time! She is always looking for volunteers to help plant and water!

By replanting native plants, and getting rid of the evil ice plant and other invasive species, Laurie and her team are making the island more inhabitable for murrelets and other seabirds. Cassin’s auklets nest under these native plants, and cannot effectively burrow under the invasive species. SBI was once a thriving Cassin’s auklet colony, but for several years there have been no known nest sites. To encourage auklets to return to Santa Barbara, they have installed a sound system that plays Cassin’s auklet calls at night.  This year they have been attending sites on the island! Check back later for more about Cassin’s Auklets!
