Abstract Populations declining due to climate change may need evolve persist. While evolutionary rescue has been demonstrated in theory and the lab, its relevance natural populations facing remains unknown. Here we link rapid evolution population dynamics scarlet monkeyflower, Mimulus cardinalis , during an exceptional drought. We leverage whole-genome sequencing across 55 identify climate-associated loci. Simultaneously track demography allele frequency throughout establish range-wide decline drought, geographically variable evolution, recovery that is predictable by both standing genetic variation at These findings demonstrate wild, showing genomic variability adaptive, but not neutral loci, predicts recovery.
