Are Restoration Seed Pools Evolving Under Commercial Propagation?

Climate change and anthropogenic activity have resulted in large-scale ecosystem degradation, necessitating an increase in restoration efforts. While previous restoration efforts have utilized seeds collected from wild populations, the demand for restoration material exceeds what can be sustainably harvested from these populations. To remedy this, large-scale propagation farms are used to produce bulk-seed. Despite the increased use of farm-raised native seed for restoration, few studies have considered the evolutionary impacts of industrial production on these gene pools. While it has been hypothesized that mechanical planting and harvesting may reduce genetic variation and drive unconscious selection, few have tested these ideas. Using the Montana-native plant Clarkia pulchella (deerhorn clarkia) we will determine if genetic variation is lost and plant traits evolve during commercial propagation, and whether these traits decrease the plants survival under stressful environmental conditions. The results of this research will test the impacts of current propagation methods, inform any necessary production changes, and increase the efficacy of restoration efforts.
