Which characteristic is important for tree species planted near sidewalks?

Minimal litter production is an important characteristic for tree species planted near sidewalks due to the maintenance considerations associated with urban landscaping. Trees that produce excessive litter, such as leaves, flowers, seeds, or fruits, can create challenges for sidewalk cleanliness and safety. Falling debris can obstruct pathways, collect in drains, or create slipping hazards, leading to potential liability issues for property owners or municipalities.

Selecting tree species that minimize litter helps to ensure that sidewalks remain clean and safe for pedestrians while also reducing the need for frequent maintenance and cleanup efforts. This allows for a more aesthetically pleasing environment and promotes the overall health of urban tree canopies without the added stress of managing excessive waste produced by the trees. Therefore, when choosing trees for urban environments, minimizing litter production is a key factor to consider.
