Koompassia excelsa
Definition
Koompassia excelsa is one of the tallest tropical rainforest trees in the world, an emergent of Southeast Asia that reaches the Philippines in Palawan. Known regionally as the tualang, it can rise above eighty meters on pale, towering trunks, and its upper branches famously harbor the nests of giant honeybees.

Also Known As
Tualang (regional name); giant koompassia; in the Philippines recorded from the forests of Palawan.
Examples and Analogies
The tree is a lighthouse standing above the canopy sea — and one with tenants: honeybees prefer its loftiest branches, so the crown that bees choose, honey hunters climb toward, and loggers in many places spare.
Usage Scenarios
- Ecotourism icon of Southeast Asian old-growth forests
- Traditional honey-hunting economies built on its bee colonies
- Comparative reference in studies of Philippine tall-tree flora alongside almaciga and other giants
Strategies
Conservation works tree by tree: because individual emergents concentrate ecological value — nests, seed, structure — retaining them in production forests yields outsized benefits compared to their timber worth.
Security and Safety Measures
Felling a tualang is regarded as among the most dangerous acts in tropical logging, and where bees nest the falling tree releases furious colonies; many communities traditionally protect the species outright.
Historical Context
The species became legendary through the honey-hunting cultures of Borneo and Sumatra, whose climbers scale the smooth trunks with hand-cut ladders; its presence in Palawan marks the northeastern edge of a range stitched across Sundaic Southeast Asia.
Challenges and Controversies
Despite its stature the species is threatened by logging of remaining lowland giants across the region; in Palawan, debate continues over balancing extraction economies with the island’s role as refuge for Sundaic flora at its Philippine limit.
