Hong Kong's Environmental Protection Department is deploying artificial intelligence and laser sensors to enhance environmental impact assessments for major projects, supporting sustainable development in the Northern Metropolis. The department has implemented two systems at Hong Kong Wetland Park in Tin Shui Wai—one for detecting bird species and another for monitoring trees—in preparation for the park's planned expansion.
Hong Kong authorities are employing artificial intelligence (AI) and laser-based sensors to improve environmental impact assessments for major projects, with plans to apply these tools to sustainable development in the Northern Metropolis. The Environmental Protection Department has been using two systems at Hong Kong Wetland Park in Tin Shui Wai since last year, in preparation for the park's planned expansion.
The AI-driven bird recognition system combines image recognition and acoustic monitoring for round-the-clock surveillance, even in inclement weather. It can identify more than 500 species, including the black-faced spoonbill and the Chinese pond heron, with an accuracy rate of more than 90 per cent.
The department is also using remote light detection and ranging (lidar) sensors to measure and record data on trees—including their locations, heights, crown widths and stem lengths—and create 3D models.
"AI applications are very helpful and can integrate environmental impact assessments with ecological conservation, allowing development to proceed in parallel," said Gary Tam Cheuk-wai, the assistant director of environmental protection. "Whether it is AI identifying birds or trees, all the data is more objective, scientific, transparent and comprehensive."
These technologies aim to make environmental data more reliable, helping Hong Kong balance development and conservation.
