The responses of rare plants to environmental stressors will determine their potential to adapt to a rapidly changing climate. We used a common garden approach to evaluate how six populations of the annual San Diego thornmint ( Lamiaceae; listed as endangered in the state of California and as threatened by the US Fish and Wildlife Service) from across the species range respond in terms of growth (biomass, height, and width) and reproduction (seed production, floral production, and next generation seed viability) to experimental differences in water availability. We found a significant irrigation-by-population interaction on the aboveground growth, wherein the differences in the magnitude and direction of treatment did not correlate directly with climate variables in natural populations.

These data are the foundation of the analyses and results published in the article "Spatio-temporal patterns of fruit extraction in the Peruvian Amazon: Implications for conservation and sustainability" (Horn et al., 2018) [1]. Here we include data on the volume of fruit arriving in the city of Iquitos, Peru from the surrounding region.
