Pyke, DA, Wirth, TA, Beyers, JL. 2013 Does seeding after wildires in rangelands reduce erosion or invasive species? Restoration Ecology 21: 415–421
Effectiveness of restoration has been debated recently. This paper presents a a meta-analysis of seeding after rangeland wildfires to determine if seedings (1) stabilize soil and (2) reduce abundance of exotics; based on 8 erosion studies and 19 exotics studies. Seeding effect on erosion is highly dependent upon initial establishment and coverage of species in successive years and has little effect in the first year after fire. Among all seeding cases, 28% reduced, 67% were neutral, and 5% increased invasive species abundance. Older seedings were more likely to show reductions in invasives than younger seedings.
Seeding after rangeland wildfire is modestly effective in stabilizing soil. Approximatley one-third of seedings inhibited exotics.
