Bangkok governor Chadchart Sittipunt on Wednesday met arborists to address a shortage of trained specialists and unveil standard guidelines and a citywide tree database to protect the capital’s canopy from construction-related damage.
At the City Hall meeting, Mr Chadchart stressed that trees should be treated as “citizens” requiring proper care at every stage — from planting and pruning to relocation and long-term maintenance.
He said Bangkok still faces several challenges, including damage to trees caused by construction projects, the absence of unified operational standards and inconsistent care across districts.
“Trees are the heart of the city. Planting alone is not enough — they must be cared for to grow strong and sustainably,” Mr Chadchart said.
The governor also highlighted a shortage of trained arborists in Thailand, noting that certification requirements are demanding and the profession remains underdeveloped. He said stronger support and training could help expand the workforce and attract younger entrants, while also offering additional income opportunities.
Key proposals discussed at the meeting included tighter regulations governing tree relocation and pruning, particularly for construction projects, with developers required to take greater responsibility for trees in affected areas.
Officials also proposed promoting professional certification to raise safety and skill standards, alongside creating a unified operations manual to ensure consistent tree-care practices across all district offices.
Another priority is the development of a comprehensive database of large and significant trees across Bangkok, which would support systematic maintenance and could also be used for environmental education and tourism.
To support these efforts, the city plans to improve infrastructure and provide appropriate tools and working systems for arborists.
Mr Chadchart has tasked the Bangkok Metropolitan Administration's (BMA) Environment Department with working alongside arborist networks to compile policy recommendations and practical guidelines within two weeks.
“I ask everyone to help propose ideas, improve work and establish shared standards to make Bangkok a more liveable city,” the governor added.
