Palaquium mindanaense

Where is this tree found?

Palaquium mindanaense, also known as ‘Pinulog’, is a species of large tropical tree endemic to the Philippines. Beyond being endemic to the Philippines this tree is only found on the island of Mindanao (its namesake), particularly in the provinces of Lanao and Cotabato, growing in low altitude primary tropical rainforest. The only available herbarium collection was made in Cotabato in 1902. The previous IUCN assessment of this species in 2019 lists it as Critically Endangered and describes its population as declining due to habitat degradation. While the exact population size is unknown, the single collection suggests that the number of individuals in the wild is very small.

Why save this tree?

This is the rarest Nato species (eastern mahogany) in the Philippines with an extremely restricted and fragmented endemic range. P. mindanaense was only re-documented in 2013 after it was first collected in 1902 – 111 years later! This species is now critically endangered with a declining population due to habitat degradation. It is known only from the provinces of Lanao and Cotabato on the island of Mindanao – areas which have lost 416 km2 of tree cover. This particular species now has an extent of occurrence less than 100km2, with the population severely fragmented. Protecting and conserving this species will reverse its continuing population decline but will also protect other associated species in its natural habitat.

How to save this species

Building local knowledge is important for the long-term conservation of this species. Local communities will be equipped with the skills to grow the species in community nurseries. Selling saplings will also provide an additional and sustainable source of income. Working with local authorities, local ordinances for the protection of the species will be prepared. Natural populations will also be increased through reinforcement planting and facilitating natural regeneration. In order to raise awareness and public knowledge of the importance of conserving this and other threatened Philippine tree species, educational material will be created and shared.

A systematic, cost-effective, and rational approach


Assessment and inventory of priority Philippine threatened trees

Carry out and assess population surveys of this species to identify previously un-recorded habitats, a vital step in the overall conservation process. The data generated will be important for updating any outdated information about this species, giving a more accurate body of knowledge which will guide researchers, academics, policy makers, policy implementers and community members in initiating local protection and conservation efforts.

Capacity building of local authorities, local communities and academics

Knowledge and skills are important elements in the conservation of this species. Increasing the knowledge of local communities will empower them to initiate local actions for conserving this species and benefit future generations. Building the capacity of local authorities, academic institutions and communities will translate into better local conservation policy, better conservation related academic curricula and more environmentally-aware communities.

Propagation of quality seedlings by local communities for habitat restoration

As local communities become more and more involved and engaged with the conservation process they will cultivate an ownership for these initiative which will prove more sustainable in the long term. Unlike other reforestation efforts where local communities are used as labourers on minimum wages, this project will fully involve local communities in the raising and planting of quality seedlings which will act as an additional sustainable source of income.

Establishment of ex-situ collections

Ex-situ collections such as arboreta and botanic gardens will serve as living showcases of Philippine native trees and as an insurance policy against their future extinction. These areas will also make threatened species more accessible to the public, promoting awareness of conservation issues and inspiring them to support local conservation efforts.

Improve local habitat protection

Improving the conditions of the natural habitat of this species will also enhance the provision of ecosystem services of the areas that benefit local communities in the medium and long term. Improved habitat protection will come from improved local conservation policy, capacity building of local communities to empower them in the enforcement of habitat protection and enhancement through enrichment planting and assisted natural regeneration.

Increasing public awareness

Produce educational materials such as interpretation signs, posters, social media content and pictorial guides to improve public knowledge of the species.
