Wallaceodendron celebicum occurs in the Philippines and Indonesia. This species naturally thrives in disturbed primary and secondary forests, inland and near the sea-shore at 50 to 980 m above sea level. It has a relatively wide geographic distribution being represented by an extent of occurrence (EOO) value of 669,956.415 km². On the other hand, the area of occupancy (AOO) value is comparatively small at 64 km² which accounts for its 16 estimated locations based on currently available information. The AOO will remain small (below the boundaries of a threatened category) upon further collection effort. The species is threatened by the effects of commodity-driven deforestation, logging activities, shifting agriculture, and urbanization; this is causing a continuous decline in AOO, EOO and quality of habitat, and potentially the population too. Although the species is widely distributed, it is assessed as Near Threatened, considering the current exposure of the species to threatening events. Conservation in situ and ex situ are important to prevent the species from being pushed into any threatened category in the future.

Wallaceodendron celebicum is native to the Philippines and Indonesia. The species is occurring in disturbed primary and secondary forests, inland and near the sea-shore of Aurora (Baler; Sierra Madre Mountains; Brgy. Diteki, San Luis), Benguet (Baguio City), Cagayan (Brgy. Cabudadan, Calayan), Camarines Sur (Pasacao), Camiguin, Masbate (Ticao Island), Oriental Mindoro (Mount Yagaw), Negros, Quezon (Brgy. Santa Cruz, Guinayangan), and Samar, Philippines as well as in Gorontalo Province (Gorontalo; Boalemo) and Sulawesi Utara (Minahassa), Indonesia. It usually grows at an elevation of 50 to 980 m above sea level (Nielsen 1992, GBIF 2022). It has an extent of occurrence (EOO) of 669,956.415 km² and an area of occupancy (AOO) of 64 km² accounting for its 16 identified locations that are continuously threatened by commodity-driven deforestation, logging activities, shifting agriculture, and urbanization (GFW 2022).

There is no information on the population size of the species. However, a decline is suspected due to continuous loss of tree cover within its distribution range.

Wallaceodendron celebicum is a small to large tree species with height ranging from five to 45 metres. It naturally thrives in disturbed primary and secondary forests, inland and near the sea-shore at 50 to 980 m above sea level (Nielsen 1992, GBIF 2022). There is no information on the phenology of the species.

Wallaceodendron celebicum is primarily threatened by land conversion and habitat degradation caused by commodity-driven deforestation, logging activities, shifting agriculture and urbanization. Based on analysed data from Global Forest Watch, a significant loss of tree cover from 2001 to 2020 is reported across the range of the species – 77,791 ha in the Philippines and 58,210 ha in Indonesia.

Wallaceodendron celebicum is used for furniture, light construction, flooring, and telegraph poles (Nielsen 1992).

The species was included in the DAO 2017-11 or the Updated National List of Threatened Species in the Philippines assessed as Vulnerable (DENR-BMB 2017). Through this administrative order pursuant to Republic Act no. 9147 or the Wildlife Resources Conservation and Protection Act of 2001, illegal and excessive tampering of the species from its natural habitats, together with other species specified therein, are inhibited. Its unauthorized utilization, trade, and disturbances made in its natural habitats are punishable by the law. The population of the species is protected in situ because of its presence in Marcos Highway Watershed Forest Reserve, Casecnan Protected Landscape, Mts. Iglit-Baco Natural Park, Samar Island Natural Park, and Ilog-Hilabangan Watershed Forest Reserve. It is also recorded in key biodiversity areas such as Babuyanes Islands, Aurora Memorial National Park, Mount Dingalan, and Ragay Gulf. In addition, it is known in at least nine botanic gardens globally (BGCI 2022). Further inventory and research are needed to estimate the total remaining population size in the wild. This will help in creating a relevant conservation action plan.
