General Information

Agathis robusta is a slow-growing but long-lived large evergreen conifer that can reach a height of 25 - 30 metres, exceptionally to 43 metres. The crown is dense, but often small in forest-grown trees, becoming more elongate when trees grow in the open. The straight, cylindrical bole can be free of branches for more than half the height of the tree and 100 - 150cm or more in diameter[

The tree naturally aborts its lower limbs as it grows to form a tall clear bole that was much valued by the early white settlers in Australia. Consequently it was extensively cut down for timber and has now become rare in many areas in the wild[

Dammar is a hard resin, obtained from various trees of Southeast Asia. Traditionally, it is used for purposes such as caulking boats and baskets, as an adhesive, a medicine, as a fuel for torches and sometimes in foods. Dammar has many commercial applications, though many of these uses are less important nowadays due to the advent of synthetic materials. Commercially, it is an ingredient of inks, lacquers, oil paints, varnishes etc, and is used as a glazing agent in foods[

Harvesting of the resin commences when the bole is around 25cm in diameter (approx 20 years old). Triangular cuts (becoming circular with age) are arranged in vertical rows around the trunk. The cuts are several centimetres wide at first, but become enlarged at every tapping and eventually become holes of 15 - 20cm in depth and width. The average number of holes for a tree about 30 metres tall and 60 - 80cm in diameter is 9 - 11 in each of 4 - 5 vertical rows. For the higher holes, the tapper climbs the tree supported by a rattan belt and using the lower holes as footholds.
The exuded resin is allowed to dry on the tree before it is collected. The frequency with which the tree is visited to refreshen the cut varies from once a week to once a month, depending on how far the tree is from the village. Tapping can continue for 30 years[
