Turn Diversity into Recovery Options
Diversity can increase recovery options: habitats provide refuges, species provide overlapping functions and genes provide tolerant variants.
The benefit is conditional on which functions and variants exist, how severe the disturbance is and whether organisms can reach suitable habitat.
After drought, a population with drought-tolerant variants may recover better than a genetically uniform population.
Show a surviving refuge, substitute function or tolerant variant—not diversity as a label alone.
High diversity is not a guarantee; the relevant level and disturbance must match.
