It holds the only known breeding site of the endangered bird Bourne's Heron.
The only known breeding location of the heron is on Santiago Island, in the Ribeira Montagna village of Achada Banana, in a nesting colony in a pair of African mahogany trees.
The kapok tree is about 25 m high and was identified as an Important Bird Area (IBA) by BirdLife International because it supported a colony of Bourne's Herons.
On the island of Grande Comore, Humblot founded a colonial company that oversaw the operations of several farms, plantations and processing factories for spices and perfumes.
Many of the species found on the mountain are unique to the Comoros and four bird species are found only on the slopes of Mount Karthala: Humblot's Flycatcher, Comoro White-eye, Comoro Drongo and Karthala Scops Owl.
