Fallen leaves may support pollinators and soil health when left in place
The study suggests that fallen leaves provide habitat for native pollinators and natural mulch for soil. Researchers found that removing all leaves could harm these benefits.
This finding highlights the ecological value of leaf litter, though the study's scope is limited to observed effects.
Leaf litter benefits
The researchers observed that fallen leaves support pollinators during winter and improve soil conditions through natural mulching.
Partial removal advised
The study suggests that if leaves must be cleared, leaving some in place preserves these ecological benefits.
Common questions
Should all leaves be removed from yards?
The researchers suggest not removing all leaves, as doing so may reduce benefits to pollinators and soil.
