On November 11, 2026, the Hong Kong Government outlined its policies for managing and removing the invasive alien species Leucaena leucocephala, including exploring artificial intelligence technology.
Invasive Species Management
Leucaena leucocephala is an invasive alien species that impedes natural succession and poses safety hazards with brittle branches, according to the Secretary for Development, Ms Bernadette Linn. Government departments remove the plant during regular vegetation maintenance to safeguard public safety.
Departments remove Leucaena leucocephala whenever it is found without waiting for it to reach a specific growth stage. Ongoing efforts to remove stumps and seedlings can gradually deplete the seed bank in the soil.
Exploration of AI Technology
To enhance tree management efficiency, the Government is actively exploring artificial intelligence technology to help identify Leucaena leucocephala along roadsides. Intelligent identification systems and image analysis will help departments quickly understand the plant's distribution and arrange clearance work.
What to do
- Report sightings of Leucaena leucocephala to the relevant department or through the 1823 hotline.
