Hong Kong’s namesake, the “heung” incense tree, is under threat by poaching, largely from mainland China.
The tree is prized for its fragrant wood, known as Chinese agarwood, which has been used for centuries to make beads, perfume, sculptures, and incense.
Agarwood can sell for more than its weight in gold, with the best pieces going for thousands of dollars per pound.
Today, the species is listed as vulnerable, and activists estimate that fewer than 300 adult trees are left in Hong Kong.
