A rare endemic mammal known as the Mindanao treeshrew ( Tupaia everetti) has been documented in Mount Apo Natural Park, broadening scientific understanding of the species' range in Mindanao. The sighting occurred during a biodiversity monitoring survey conducted by the Department of Environment and Natural Resources (DENR) Region 12 from April 27 to May 1, 2026.
The animal, locally called tingkolit by the Ubu Monuvu indigenous group, was observed in the park's forested areas within Cotabato province.
Discovery in Mt. Apo
An adult male Mindanao treeshrew was recorded by researchers as part of the ongoing biodiversity monitoring program of the Mt. Apo Natural Park. The survey team identified the mammal through direct observation and photographic documentation.
The find is significant because it extends the known habitat range of the Mindanao treeshrew to higher elevations. Previous records placed the species in lower montane forests, but this sighting confirms its presence in Mount Apo, the country's highest peak.
Scientific Implications
Researchers said the updated range could help in reassessing the species' population dynamics, ecological requirements, and resilience to environmental changes such as climate variability and habitat disturbance. The discovery was announced by DENR-Region 12, which highlighted the importance of sustained biodiversity monitoring across different elevations and habitat types.
"The discovery is significant not only because of the species' rarity but also because of where it was found," researchers said in a statement. "Scientists said the updated range could help researchers reassess the species' population dynamics, ecological requirements, and resilience to environmental changes."
About the Mindanao Treeshrew
The Mindanao treeshrew is an endemic mammal found only in Mindanao. It is a diurnal species, meaning it is active during the day, and feeds on insects, fruits, and small invertebrates.
Despite its name, the treeshrew is not a true shrew but belongs to the order Scandentia. It is considered a primitive placental mammal, with a body length of about 18 to 22 centimeters and a tail of similar length. Its fur is typically brownish with lighter underparts.
Local communities in Mindanao have long known the animal as tingkolit, but scientific documentation of its presence in Mount Apo has been limited. The recent sighting provides valuable data for conservation planning.
Conservation Significance
The sighting comes at a time when biodiversity monitoring in protected areas has become increasingly important. Mount Apo Natural Park, a UNESCO World Heritage site, is home to a wide range of endemic flora and fauna. However, it faces threats from deforestation, agricultural expansion, and climate change.
The discovery of the Mindanao treeshrew in the park underscores the need for continued protection of its remaining forest habitats. The DENR said the find highlights the importance of sustained biodiversity monitoring across different elevations and habitat types, particularly in ecologically rich but vulnerable areas such as Mindanao.
The species is currently listed as near threatened by the International Union for Conservation of Nature (IUCN), primarily due to habitat loss from logging and conversion into agricultural land.
Forward-Looking Statement
The DENR said it will continue its biodiversity monitoring program in Mount Apo Natural Park to gather more data on the distribution and population of the Mindanao treeshrew and other endemic species. The information will be used to update conservation strategies for the park and surrounding areas.
