EXECUTIVE SUMMARY California Institute of Environmental Studies, partnering with the National Park Service, has been actively restoring the native shrub habitat of Santa Barbara Island since 2007, as funded by the Montrose Settlements Restoration Program. The goals of this project are to increase the amount of nesting habitat for Scripps’s Murrelet (Synthliborhamphus scrippsi) and restore an historic nesting colony of Cassin’s Auklet (Ptychoramphus aleuticus). This effort has resulted in approximately 7.7 acres of restored habitat on the island, utilizing nearly 30,000 island-sourced native plants. In the 2014 nesting season, 186 Scripps’s Murrelet clutches in 141 active nest sites were monitored on Santa Barbara Island. We could reliably determine the fates for 182 nests. Nesting data were collected at five plots in 2014: Arch Point North Cliffs, Bunkhouse, Cat Canyon, Landing Cove, and the Landing Cove Dock.
