Ecological restoration is often conducted with limited consideration of genetic diversity and the environmental factors that drive variation within species. In a new study published in AoB PLANTS, Hufford et al. examined the genetic diversity and environmental variation among 16 populations of Stylidium hispidum, an endemic southwestern Australian triggerplant. As a result they were able to estimate the seed transfer distance within which genetic divergence is low and population fitness is less likely to be impacted by maladaptation, and identify environmental variables that may be relevant for future restoration of this species.
