SAN JOSE, Occidental Mindoro – In a workshop here organized by the Mindoro Biodiversity Conservation Foundation Inc. for its Ilin and Ambulong Islands Forest Conservation Project, I was surprised at the revelation that the sugar industry in Negros has contributed to the depletion of an important endemic species of the country, the Philippine teak (Tectona philippinensis).
It is only known to grow in Ilin and Ambulong islands in San Jose town, Occidental Mindoro, and in the towns of Lobo and San Juan in Batangas. Because of its restricted distribution and population depletion, the Philippine teak has already been declared as critically-endangered species by both the Department of Environment and Natural Resources and the IUCN-World Conservation Union.
This means that the species is under protection and its exploitation is already prohibited. Unfortunately, some local communities are still utilizing this species because it is commercially viable, although they also attest that the population of the species in Ilin and Ambulong Islands is now getting limited.
While I was facilitating the workshop, which was designed to engage local stakeholders in the implementation of MBCFI’s conservation project in the two islands, I asked for the factors that contributed to the reduction of the species’ population in the two islands of San Jose. Some people, who have been living in Ilin and Ambulong for some time now, testified that bulk of Philippine teak and molave trees were cut and transported from the islands to Negros to supply the need for railways of trains, which were used then in transporting sugarcane from haciendas to sugar mills.
This species of tree is known for its hardwood quality. It is usually found in coastal to lowland limestone forest and tends to dominate the semi-deciduous forests, the IUCN said.
The IUCN recommended the implementation of a conservation program that would re-establish the stable natural population of T. philippinensis in its known habitat. It also suggested that a rapid assessment of the species and long-term ecological research shall be conducted, to determine the physical and biological characteristics of the habitat, coupled with a recovery and management program, public education, community consultation and resource stewardship and policy initiatives.
The MBCFI, with funding support from the Philippine Tropical Forest Conservation Foundation Inc., and the Malampaya Ventures, is initiating a project to enhance the population of the Philippine teak in Ilin and Ambulong Islands. It also aims to establish woodlots to address the timber requirements of the local communities, and increase the awareness of local folks on the importance of the teak and other endemic species and their associated habitats.
Ilin Island, in particular, is the only known locality for the Ilin Bushy-tailed cloud rat, or the Hairy-tailed cloud rat (Crateromyspaulus). This species was once listed as critically endangered, but is now categorized as Data Deficient, because of its limited information. The IUCN said the species was only known from the holotype, that was reportedly purchased in Ilin Island. Several attempts to rediscover this cloud rat in the island failed.
