Members of this genus generally only regenerate naturally in the shade of the forest. Seedlings and saplings can persist in dense forest shade for many years. In their first 2 years the young plants cannot tolerate major openings in the canopy, but after they are well established (about 120cm tall) the canopy can be opened up around them to speed up their growth[

]. The resin is obtained by cutting a hole in the trunk near the base (about 90 - 150cm from the ground) and then dipping out the resin with a spoon as it collects there. To prolong the flow, a fire made from dead leaves or brushwood is made in the hole at intervals - this burns off the dried resinous film and allows the resin to flow again[

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[

]. We do not have any more specific information for this plant, but a general description of the wood is as follows:-
The heartwood varies from light to dark red-brown or brown to dark brown, sometimes with a purple tint; it is usually well defined from the 5 - 7cm wide band of gray or buff sapwood. The texture is moderately coarse; grain straight or shallowly interlocked; lustre low; there is a strong resinous odour when freshly cut, it is without taste. The wood is moderately heavy to heavy; moderately hard; somewhat durable, being resistant to dry wood borers, fairly resistant to fungi but susceptible to termites, though silica content may be high, resistance to marine borers is erratic. It seasons slowly, with a high risk of checking and distortion; once dry it is poorly stable to moderately stable in service. Silica content is variable, generally less than 0.5%. The wood generally saws and machines well, particularly when green; blunting of cutters can be moderate to severe due to silica content, stellite-tipped and tungsten carbide tools are recommended; it is sometimes difficult to glue; resin adhering to machinery and tools may be troublesome and can also interfere with finishes; nailing and screwing are good, but require pre-boring; gluing is correct, but care is required because of the resin. The wood is used for general construction work, carpentry, panelling, joinery, framework for boats, flooring, pallets, chemical processing equipment, veneer and plywood, suggested for railroad crossties if treated[
