When a weed is not a weed: succession management using early seral natives for Intermountain rangeland restoration

Abstract

• •

  Restoration practices employed in semiarid sagebrush steppe of the North American Intermountain West are typically based on objectives to restore habitat to mid- to late-seral plant communities.

• •

  Incorporating succession management techniques including representation from early seral community species in restoration plans and seed mixtures could bridge the temporal gap between disturbance and stable climax conditions.

• •

  Early seral species evolved to establish quickly and occupy disturbed soils, reduce erosion, and provide a food source for wildlife. Additionally, they alter soil chemistry and biology dynamics that favor transition to later seral phases. Many early seral natives reduce exotic weed growth and seed production.

• •

  Despite their benefits, early seral species have poor representation in restoration practices largely due to cultural biases.

• •

  Continued investigation of early seral natives in restoration practices will better elucidate the benefits of this underused group. Developers of plant materials should focus on developing a broader suite of early seral germplasm sources for Intermountain restoration activities.
