• Summer-drought stress is the dominant warming signal here, not winter cold — the wet season is shortening and summer fog frequency is declining at the coast.
• Western red cedar dieback and Douglas fir branch flagging are now well-documented across the southern half of the ecoregion; both signals track multi-year cumulative drought, not single-year extremes.
• Garden-relevant: native ferns and rainforest understory species (sword fern, vine maple, salal) need supplemental irrigation in years they historically didn't; consider drought-adapted natives from the south end of their range.
