Zoned Out: An Analysis of the Genetic Diversity and Structure of Seeds of Success Accessions.

Seed zones are a commonly used guideline for sourcing plant material for restoration projects, which rely on the assumption that seeds sourced from specific areas will be locally adapted to regional environmental conditions. This assumption has been supported by various genetic and common garden experiments, but the relevance to the success of restoration projects has not been tested in the field. Seeds of Success (SOS) is a program implemented by the Bureau of Land Management to collects seeds from species native to the western United States for use in restoration projects utilizing the logic of seed zones. However, the genetic variability within and between seed accessions is largely unknown. If seeds from the same species demonstrate a low amount of genetic structure or diversity throughout their range, there is no evidence for local genotypes and seed zone collecting is not necessary. If seeds are equally genetically diverse and demonstrate a high amount of structure throughout their range, there is evidence for local genotypes, which could impact restoration project success. Therefore, this project aims to determine how genetically distinct and diverse individuals are within and between accessions of SOS seeds common to the sagebrush steppe community of the western United States. Using microsatellite analysis, genetic structure and genetic diversity measurements (including phi-st and Fst values) will be used to examine these common members of sagebrush communities. This data will indicate if there is genetic evidence for using exclusively locally sourced seed material in restoration projects and will contribute to ongoing field restoration trials.
