Innovative Tree Map Technology Aims to Reduce Allergies in Major Australian Cities

Researchers from Edith Cowan University (ECU) have developed a pioneering visualization tool that maps allergenic trees across four of Australia’s largest cities. This innovative approach seeks to help residents avoid high-risk areas and mitigate allergy symptoms such as hay fever and asthma. Urban green spaces are vital for mental and physical health; however, for allergy sufferers, exposure to pollen can significantly impact well-being. Approximately 25% of Australians experience hay fever, with many also managing asthma, leading to substantial healthcare costs and absenteeism.

Recognizing that urban environments often have higher concentrations of aeroallergens like pollen, Dr. Mary Hanson explained that the research leverages existing free-to-download programs augmented with new allergenicity visualizations. By analyzing city council data from Perth, Melbourne, Sydney, and Adelaide, the team identified pollen hotspot zones. This information allows individuals to adapt their routines — for example, taking alternate routes — to reduce allergen exposure, potentially improving quality of life.

An upcoming online platform will enable users to explore allergen risks within Perth’s cityscape. Additionally, resources like the Perth Pollen website and app provide real-time pollen forecasts, supporting allergy management. The research team plans to expand pollen risk mapping using machine learning and artificial intelligence, aiming to make pollen data more accessible for the wider community.

This advancement not only contributes to public health by offering personalized environmental insights but also highlights the importance of urban planning and data-driven strategies in allergy prevention.
