Reclaiming forest land after industrial activity such as oil and gas extraction requires re-establishing self-sustaining ecosystems consisting of native plant species. This greenhouse study was intended to help those involved in reclamation choose native plant seeds that will thrive in the particular soil and climate of a reclaimed site. It determined the germination and early growth of three common native species (hairy wild rye, fireweed and goldenrod) found in the understory (the vegetation underneath the forest canopy). Their growth was tested in different soil types and watering levels found in reclamation sites. Germination of all three species occurred only when a standard, high moisture level was maintained and did not occur when watering was restricted. Seedlings produced more biomass as a result of more watering, in all species and soil types. However, the growth increase with watering was limited on certain soil types because of limited nutrient supplies. The species that had the greatest growth potential was also most sensitive to drought. These results can be used to aid in choosing and using appropriate native plant seed mixes in reclamation sites.
