A tree may look healthy but be dying; satellites can spot it before humans

The health of urban trees, often appearing vibrant on the surface, can mask underlying decline. A new project by the Brno-based company ASITIS, called UpGreen, is employing satellite imagery to detect these hidden issues before they become visually apparent to humans.

UpGreen's technology allows for the comparison of tree conditions over multiple years. This historical data analysis helps identify subtle changes and early signs of stress or disease in urban forests. By flagging trees that are beginning to struggle, the system enables timely intervention and management.

Experts emphasize that simply increasing the number of trees in cities is insufficient. The critical factor, they argue, is ensuring trees reach maturity, a stage where they can effectively deliver essential ecosystem services. These services include improving air quality, mitigating the urban heat island effect, and supporting biodiversity.

ASITIS's UpGreen project offers a proactive approach to urban forestry. By leveraging advanced remote sensing technology, it provides city managers and environmental agencies with valuable data to maintain healthier, more resilient urban green spaces. This focus on long-term tree vitality is crucial for the sustainability and well-being of city environments.
