The Philippines has rich biodiversity and natural resources.
There are tens of thousands of plant species distributed in its more than 7,000 islands and some remained undiscovered by humans.
Somewhere out there in the middle of the jungle, surely there are thousands of old trees in there and some may have been died already due to their age, but since they left undiscovered, it is hard to distinguish their real age.
The size of the tree cannot be considered a deciding factor to determine the age of the tree. Some species are small and some grow to huge size despite their young age.
This list provides only the oldest known Philippine trees discovered by humans and most of these are actually found outside the jungle.
Balete, acacia, mangoes – are some of the biggest and oldest trees in the Philippines, but none of these are considered endemic and native to the Philippines. These trees did not grow naturally inside Philippine jungles unless there is human intervention.
The following is the list of oldest Philippine trees known to humans.
#1. Canlaon Century Balete Tree
The Balete tree (Ficus benjamina) inside the OISCA Farm in Lumapao, Canlaon City, Negros Oriental, Philippines is estimated by botanists from Silliman University to be around 1,328 years old. It would take at least 42 men to encircle its trunk.
At the heart of this wide tree trunk is a cavity where lizards, bats and many insects have made it their home. With fireflies lighting it at night like a year-round Christmas tree, it is one of the city’s main tourist attraction.
The Canlaon Century Balete Tree is considered the oldest publicly known tree in the Philippines.

It is possible for adult people to squeeze into the center of its root network.

#10. Kalayan Tree
The centuries-old Kalayaan Tree or Siar (Peltophorum pterocarpum), located in a churchyard in Malolos, Bulacan province, has been a living witness to many historic events that transpired in the area.
It was in Barasoain Church where three important events of our country took place: the convening of the First Philippine Congress on Sept. 15, 1898; the promulgation of the Philippine Constitution, popularly known as the Malolos Constitution on Jan. 21, 1899; and the inauguration of the First Republic on Jan. 23, 1899, establishing the Philippines as the first democratic country in Asia.
The Siar was then a young tree standing a few meters from the convent where Gen. Emilio Aguinaldo found temporary refuge. Revolutionary field officers waited under its shade to see the general and report on the battles won and lost by the revolutionaries. It was where Katipuneros waited for battle orders or military mission.
