Table 1. Seven attributes of Pacific salmon species that contribute to their resilience, and a primary resilience benefit of each attribute.

Resilience attribute Primary resilience benefit
Multiple, independent reproducing populations Reduced extinction risk
High reproductive capacity Strong capacity to recover from mortality events
Metapopulation structure Optimal habitat use
High genetic diversity Adaptive capacity
Phenotypic plasticity Flexible response to variable environments
Variable life-history tactics A well-stocked adaptive tool kit
Opportunistic use of habitat Rapid response to new opportunities
