2023-01-01Impact of roadside conifers vegetation growth on air pollution mitigation
This study examines how the growth of conifer trees planted alongside roads affects their ability to reduce traffic-related air pollution over time. Researchers found that as conifers grow taller, they become less dense, and the ideal tree height for maximum pollution reduction is between 4 and 6 meters. The findings suggest that regular pruning is essential to maintain roadside vegetation barriers at their most effective size for improving air quality in nearby communities. -
