California's native wildflowers are threatened by invasive grasses that create dense layers, preventing seed germination and hindering biodiversity.

The study emphasizes that simple actions like raking can have meaningful ecological impacts, inspiring community involvement in restoration efforts.

A study from the University of California, Riverside (UCR) suggests that raking away surface debris can help restore biodiversity and reduce fire risk in grasslands.

Research conducted in grasslands near the UCR campus showed significant increases in plant diversity due to raking, with invasive grasses like ripgut brome declining.

Lead author Marko Spasojevic noted that raking allows light to reach native seeds, promoting their growth and enhancing the ecosystem.

Raking involves removing surface debris like leaves and dead grass to prepare soil for planting and improve air circulation, benefiting native flora.

The findings provide practical strategies for land managers to restore biodiversity in California's ecosystems, which are crucial for local wildlife and pollinators.

While raking helped native wildflowers, it also increased certain exotic wildflowers, such as mustard, which can be invasive.

The study compared raking to other invasive grass management methods, finding it to be a cost-effective and eco-friendly alternative.

The SEEDS initiative, started by UCR students, revived the research project during the COVID-19 pandemic, involving over 25 undergraduates in the effort.
