ALT Fig. 3 A diagram illustrating management options discussed by the “Oaks and Pines” breakout group, using the Santa Cruz Bishop Pine Community as an example. Shifting fog patterns deliver reduced summer moisture, while extended heat and drought stress create conditions for pathogens like bark beetles to thrive. Participants explored the decision-making space available to managers in this scenario, from “Resisting” the trajectory of change (replacing lost pines, treating beetles, and irrigating during drought) to “Accepting” the change (allowing wildfire and nonnative species encroachment, monitoring and educating island users), to “Directing” the change (encouraging community shift to mixed chaparral with selective thinning and planting of resilient shrubs, translocating pines to enduring climate refugia).
