Mount Hamiguitan World Heritage Book Project

Mount Hamiguitan
A World Heritage Sanctuary 

Every now and then a project comes up that I get really excited about. When I was asked to photograph the newest Philippine World Heritage Site, Mount Hamiguitan, I knew right away that this would be an amazing project to work on. Mount Hamiguitan is the only Heritage Site in Mindanao and was inscribed in 2014 after local initiatives strongly advocated and worked for the park to become listed under UNSECO. The park’s biologically diverse flora and fauna, high number of endemic species, and unique pygmy forest were a few of the key characteristics for which the site was listed.

I was given a unique opportunity to photograph the park for a coffee table book about the six UNESCO sites in the Philippines. The book produced by ArtPostAsia and the Aboitiz Foundation was recently published and will be available sometime in the coming months. Because of the coordination involved, size and remoteness of the park, I would not have been able to visit this beautiful and majestic place if it wasn’t for this project. Most of the park is still closed off to the general public and special permits are usually only granted to researchers. This could change in time, but they are being very cautious about opening up the core zones of the park to reduce human impact. However, there is a very modern museum and welcome center that people can visit to learn more about the park and I would highly recommend this. There are also some shorter trails you can hike on near the welcome center.

Mount Hamiguitan’s Pygmy or “Bonsai” forest is a unique ecosystem where the local vegetation has been stunted because of unfavorable soil conditions.

Mount Hamiguitan is estimated to have 1,380 different species of plants and animals, 341 of which can only be found in the Philippines, and 12 of which are found only at Mount Hamiguitan.

It took us a full day of hot, humid and upward hiking to reach our base camp just outside of the Pygmy forest. It was the start of the rainy season and we were constantly monitoring and expecting wet weather to come. Our team was made up of about 14 men. Transporting all of our gear, generator, fuel, food and other supplies was no easy task. We camped for 5 nights making day trips to different areas. Fortunately, we didn’t see any rain for the duration of our stay and the sky even opened up one night to let us witness the Milky Way. This trip would not have been possible without the support and help of the whole team involved. Dr. Roy Ponce was our team leader and deserves a great amount of credit for his work in getting Mt. Hamiguitan listed as a World Heritage site. I couldn’t have asked for a better or more entertaining group to be with for a week in the forest.

I have been to many different types of forests throughout the world and I would have to say that this trip was one of my most intimate and surreal experiences with nature. The forest is extremely unique and I felt alive being surrounded by it.

The Mount Hamiguitan Range Wildlife Sanctuary represents a complete, substantially intact and highly diverse mountain ecosystem, in a significant biogeographic region of the Philippines. Its diversity of plants and animals include globally threatened species as well as a large number of endemic species including those species that exist only in the Philippines, only in Mindanao and only in the nominated property. The fragile tropical “bonsai” forest that crowns the Mount Hamiguitan Range Wildlife Sanctuary epitomizes nature’s bid to survive in adverse conditions. As a result of its semi-isolation and its varied habitat types growing in dissimilar soil and climate conditions, its biodiversity has shown a significantly high level of endemicity that has led scientists to believe that there may be more globally unique species waiting to be discovered in the area.  

The combination of terrestrial and aquatic ecosystems within the boundaries of the property and the large number of species inhabiting each makes the Mount Hamiguitan Range Wildlife Sanctuary home to a total of 1,380 species with 341 Philippine endemics that include critically endangered species such as the iconic Philippine Eagle (Pithecophaga jefferyi) and the Philippine Cockatoo (Cacatua haematuropygia), as well as the trees Shorea polysperma, Shorea astylosa, and the orchid Paphiopedilum adductum. Its high level of endemicity is well exemplified by the proportion of its amphibian (75% endemic) and reptile (84% endemic) species. (Source: UNESCO)

We came across a group of researchers from the University of the Philippines (UP) Los Banos and the National Museum during our descend from base camp. They were spending a few weeks there collecting specimens, looking for new species, and doing a variety of other long-term research. In the group were specialists looking at everything from ants, birds, reptiles and flora. I was told that during their first day there they discovered a new species of ant while hiking along the trail. This is amazing to me and is a clear example of how diverse Mount Hamiguitan is. It’s highly likely that many more new species will be discovered in the park. 

Although the park is protected there are still some challenges that are ongoing. Small-time offenders such as illegal gatherers and poachers sometimes enter the park to collect tree resin or rattan. We saw some signs of this at lower elevations. Prior to becoming a protected area there were some mining claims on the east coast of the park which could clearly be seen from near the summit. However, recently I heard the mining operations have stopped because the DENR under Sectary Gina Lopez revoked their permit. I can see how tourism in the area could also put more pressure on the parks resources, if not done correctly. The park is still closed to mountaineers and I know they are going to monitor very closely the effects visitors might have. Spending time in the park, learning about its history, and seeing first hand the diversity of life there energized me and once again reminded me how important local conservation initiatives are in protecting places like Mount Hamiguitan.

(above) The Philippine Tarsier (Tarsius syrichta) also makes its home within Mt. Hamiguitan. Upon researching, I found there is only one species of Tarsier in the Philippines but with three separate subspecies found in Mindanao, Leyte and Bohol. However, it is also noted that these subspecies classifications required more research.

This is a chapter book with all of the six Philippine World Heritage sites included. Because Mt. Hamiguitan is the newest site it got the cover as well. The regular edition of this publication should be available soon and I must say the print quality and design came out fantastic.

    Hello Jacob!
    We are from the Protected Area Superintendent’s Office of Mt. Hamiguitan Range Wildlife Sanctuary. Way back in 2016, the photodocumentation which your team conducted was realized thru the collaboration with Dr. Roy Ponce and with our Office. Indeed, your team was able to produce awesome photographs of the various features of MHRWS. The collaboartion was timely considering that we, at our level, cannot produce such quality due to skills and equipment limitations that our Office has. With this and in view of performing our mandate and functions in the protection and conservation of Mt. Hamiguitan, we would like to request your end to allow us to borrow these photographs so that we can primarily use it in our Communication, Education and Public Awareness (CEPA) campaign program aimed at raising the awareness of the people on conserving and protecting Mt. Hamiguitan and help maintain its status as a UNESCO World Heritage Site and an ASEAN Heritage Park. We hope to have your favorable response on this matter. Thank you very much!
