We would like to thank Channel Islands National Park, including Kelly Minas, Don Morris, and Ann Huston, for the help with this project. This project was supported by Channel Islands National Park (135414, P11AC30805, Jazwa; 1443CA8120-96-003, Kennett), the National Science Foundation (BCS-1338350, Jazwa; BCS-1460369, SBR-9521974, Kennett), University of California, Santa Barbara, California State University, Long Beach, the University of Oregon, and Pennsylvania State University. Brendan Culleton provided insight about the IFD and Claire Ebert helped with some of the GIS work. Don Morris, Gil Unzueta, Henry Chodsky, Stephen Hennek, Terry Joslin, and Reilly Murphy assisted with excavations. Sheryl Gerety assisted with editing and proofing of this document. We would also like to thank Catherine Cameron and James Skibo, along with two anonymous reviewers, for their comments on this manuscript.

N2 - Using targeted survey, excavation, and radiocarbon dating, we assess the extent to which human settlement patterns on California’s northern Channel Islands fit predictions arising from the ideal free distribution (IFD): (1) people first established and expanded permanent settlements in the regions ranked high for environmental resource suitability; (2) as population grew, they settled in progressively lower ranked habitats; and (3) changes in the archaeological record associated with high population levels such as increases in faunal diversity and evenness in high-ranked habitats are coincident with the expansion to other areas. On Santa Rosa Island, the early permanent settlements were located in both high- and middle-ranked locations, with the most extensive settlement at the highest ranked locations and only isolated sites elsewhere. Settlement at a low-ranked habitat was confined to the late Holocene (after 3600 cal BP). Drought influenced the relative rank of different locations, which is an example of climate adding a temporal dimension to the model that episodically stimulated population movement and habitat abandonment. Because the IFD includes a wide range of cultural and environmental variables, it has the potential to be a central model for guiding archaeological analysis and targeted field research.
