Study Reveals Shrubs' Dual Role in Forest Recovery After Wildfires

Research highlights how shrubs can either support or hinder tree regrowth, depending on timing and environmental factors.

California, Davis researchers found that shrubs can both promote and compete with tree seedlings after wildfires, depending on conditions.
Tree planting within a year of a wildfire is most effective in areas with dense shrub growth to reduce competition for resources.
In regions with sparse shrub cover, delaying planting by three years allows beneficial shrubs to provide shade without overwhelming resources.
The study emphasizes the importance of targeted, data-driven restoration strategies as climate change increases wildfire frequency and severity.
Researchers are using aerial imagery and field surveys to refine reforestation methods and address the backlog of severely burned areas.
