GREEN INFRASTRUCTURE UTILISING BRYOPHYTES FOR ECOSYSTEM SERVICES PROVISION IN URBAN AREAS

Urban ecology examines the intricate interactions within socio-ecological urban systems, with green infrastructure (GI) emerging as a vital tool for sustainable development by enhancing ecosystem services and promoting human well-being. This study aimed to provide a comparative assessment of moss-based GI, focusing on its capacity to reduce particulate matter (PM10) and absorb rainwater. To evaluate PM10 absorption, laboratory experiments were conducted in a controlled pollution chamber using a vertical barrier design. Three moss species (Dicranum scoparium, Plagiomnium affine, and Hypnum cupressiforme) were tested using two Pollutrack PM10 sensors. Results from 18 tests revealed an average PM10 reduction efficiency. For rainwater absorption, a complementary experiment assessed four moss species (Dicranum scoparium, Pleurozium schreberi, Ceratodon purpureus, and Hypnum cupressiforme) in a horizontal setup. Moss samples, dehydrated and weighed, were sprayed until saturation to determine their water absorption relative to dry mass. The study confirmed that mosses can absorb at least 50% of their dry mass. Overall, the findings demonstrate the significant potential of specific moss species for improving urban air quality and managing stormwater. While laboratory results are promising, further long-term research under real-world outdoor conditions, considering seasonal variations, is essential to validate these efficiencies and promote broader implementation of moss-based GI solutions.
