In 1994, Isabela State University, Conservation International Philippines and CTFS/STRI initiated the Palanan Permanent Forest Dynamics Plot (PFDP) as an 8-ha plot, later expanded to 16-ha in 1998. 

Since 2010, the management of the Palanan PFDP had passed on to the Institute of Biology, College of Science, University of the Philippines Diliman (UP Biology). 

The Palanan PFDP is located in an aseasonal forest in the typhoon belt, and is being compared with the Luquillo FDP in Puerto Rico's hurricane belt. The three-fold mission of the Palanan FDP is: (1) to examine the performance and abundance of species used for timber and non-timber forest products; (2) to understand the dynamics of forests under a full range of natural disturbance regimes; and (3) to develop a management plan for the sustainable use of forest products within local communities. This mission reflects the fact that illegal logging, over‑exploitation of forest resources, and land-use changes have affected the Palanan ecosystem and that economic and social pressures threaten the integrity of the area's indigenous Agta community. The Palanan PFDP will provide some of the necessary biological information needed to preserve and use forest resources responsibly, and it will also help promote locally-owned and operated enterprises that increase incentives for the conservation of biological diversity.

 

A re-census had been undertaken in 2004, 2010 and 2016, with supertyphoons hitting Palanan either before the recensus [Typhoon Imbudo (Category 4) in July 2003] or after the recensus [Typhoon Meji (Category 5 )in October 2010]and [Typhoon Haima (Category 5) in October 2016].  

In 2012, studies on other aspects of the Palanan PFDP such as the ecology of bat assemblage commenced and continue to date. Pollination and seed dispersal studies as well as genetic studies of trees and bats are also ongoing.

 

Funding had been provided by various Philippine institutions such as the University of the Philippines Office of the Vice President for Academic Affairs’ Emerging Inter-Disclipinary Research Program (UP OVPAA EIDR), the Commission on Higher Education, the University of the Philippines Diliman Office of the Vice Chancellor for Research and Development (UPD OVCRD), the Diliman Science Research Foundation, the Energy Development Corporation (EDC), the Forest Foundation Philippines and the Department of Science and Technology through the Philippine Council for Agricultural and Aquatic Resources Research and Development (DOST-PCAARRD), among others. The Center for Tropical Forest Science Forest Global Earth Observatory (CTFS Forest GEO) continues to provide resources in the maintenance of the Palanan PFDP and in the conduct of all re-censuses.
