Planting 4 month old Ficus racemosa (Tangkol) seedlings in the ground at the BORA Sabah Ficus Germplasm Centre at Tabin in Sabah.
The purpose is to create an orchard which can be used for vegetative propagation of Ficus racemosa in the future. When these plants are mature the branches will be marcotted or grafted onto younger root-stock to produce plants with early fruiting.

Ficus racemosa is a common fig tree of river banks throughout lowland Borneo. The local names are Tangkol (Sabah Malay) Nunuk Ragang (Kadazan Dusun) or Pohon Loa (Indonesian). Tangkol is one of the most prolific fruit trees in the world providing 6 to 8 crops of figs a year.
Almost all the wildlife of Borneo’s rivers and the the surrounding forest depends of the fruit of Tangkol. Primary consumers are hornbills, bats, fish, civets, macaques, proboscis, orangutans and elephants. Nearly all the fish eagles, darters and herons found along Borneo’s rivers ultimately depend on Tangkol to feed the fish that they eat.
Preparing the soil for the seed trays.
The current target is to produce 1,000 Tangkol saplings per month. These saplings will mainly be planted on oil palm estates to create wildlife corridors especially along river banks where the natural vegetation has been damaged. Over 70 different native species of Ficus are grown at BORA and thousands of saplings of many different species are produced every month.
At four months old Tangkol saplings can be planted in the ground.
This Tangkol sapling is now 2 metres tall and eight months old. It was originally planted out at 4 months old.
Tangkol normally starts fruiting at around 10 years old. This photo shows a 10 year old branch being grafted on to six month old root stock to create a plant with early fruiting.
