Rubber tapping in Indonesia, 1951. Rubber tapping is the process by which latex is collected from a rubber tree. The latex is harvested by slicing a groove into the bark of the tree at a depth of one-quarter inch (6.4 mm) with a hooked knife and peeling back the bark. Trees must be approximately six years old and six inches (150 mm) in diameter ...
Rubber tapping normally takes place early in the morning, when the internal pressure of the tree is highest. A good tapper can tap a tree every 20 seconds on a standard half-spiral system, and a common daily "task" size is between 450 and 650 trees.
Henry Nicholas Ridley CMG (1911), MA (Oxon), FRS, [1] FLS, F.R.H.S. (10 December 1855 – 24 October 1956) was an English botanist, geologist and naturalist who lived much of his life in Singapore. He was instrumental in promoting rubber trees in the Malay Peninsula that led to a level of rapid deforestation, instrumental in the 1926 Great Flood.
Hevea brasiliensis is a tall deciduous tree growing to a height of up to 43 m (141 ft) in the wild. Cultivated trees are usually much smaller because drawing off the latex restricts their growth. The trunk is cylindrical and may have a swollen, bottle-shaped base. The bark is some shade of brown, and the inner bark oozes latex when damaged.
In the past, the Orang Kanaq were slave workers tapping trees in rubber plantations. [6] The government has repeatedly tried to attract Kanaq people, like other Orang Asli tribes, to produce plantation crops. At first, a small rubber plantation was created with an area of 3.02 hectares, in which each family received four rows of trees.
They replaced native trees, including those with medicinal or ritualistic value such as the sasswood, red ironwood, and Cassipourea firestoneana trees, with meticulously arranged rows of rubber trees. [39] Tapping operations commenced shortly thereafter, and by 1940, Firestone had achieved a production of over 7,000 tons of latex per year. [40]
Rubberwood. Rubberwood is a light-colored medium-density tropical hardwood obtained from the Pará rubber tree (Hevea brasiliensis), usually from trees grown in rubber plantations. [1] Rubberwood is commonly advertised as an "environmentally friendly" wood, as it makes use of plantation trees that have already served a useful function.
Slaughter tapping is an obsolete method of extracting large quantities of natural latex from rubber trees in a forest environment. Before commercial exploitation of latex-bearing trees such as Hevea brasiliensis in the Amazon Basin and Funtumia elastica in the Congo, native populations limited harvesting to non-lethal tapping of the latex ...
