Seeding native species to promote ecosystem recovery after fire

Science Spotlights Posted on: July 24, 2019
The use of prescribed fire to reduce expansion of pinyon and juniper to sagebrush ecosystems is a commonly used by managers but can have unwanted consequences. In this Joint Fire Sciences Program Demonstration Project, we show how seeding native species after prescribed fire can decrease invasion of nonnative annual grasses in sites with low resistance.

Seeding native species increases resistance to annual grass invasion following prescribed burning of semiarid woodlands

Exotic grass invasions are often facilitated by disturbances, which provide opportunities for invasion by releasing pulses of resources available to invaders. Where disturbances such as prescribed fire are used as a management tool, there is a pressing need to identify ecosystem attributes associated with susceptibility to disturbance-induced invasion.
