Back Cover: Top: To effectively restore degradation of the landscape due to the rapid boom in energy development, an understanding of both the role of soils and weed invasion is necessary. In this issue, Espeland and colleagues test the role of cover crops in ecosystem recovery after energy development and the potential for dispersed reclamation activities to facilitate weed invasion and spread.

Middle: Understanding the appropriate collection zones for native plants used in restoration activities is a key concept for successful restoration.
