In northern, southern, coastal, and interior California, examples exist of paired sibling Arctostaphylos subspecies exhibiting two alternate life strategies for surviving disturbance: resprouting and obligate seeding. This is a wonderful opportunity to observe how natural selection might favor one life strategy type over another, particularly in “an era of rapid climate change."
