Leo,
An interesting theory. The sea levels were much lower in the last Ice Age too - so California was 50-100 miles wider along the coast. Bays were river valleys, near shore shallows were forests/grasslands and the Channel islands were just hills. It's just as possible that plants migrated to milders areas (especially since now-arid inland areas would have gotten more rain).
