Climbing Days autumn season on Rubber Tree Plantation

Did You Know LeCoq Sportif age of brand 130 year.
Im using from 1991 now 23year in my collection
Autumn Season in Perlis,Malaysia 
We choose a boulder rock climbing new site in rubber tree plantation. It a great place & feel the season under the tree & wind.The rubber tree in Science name `Hevea brasiliensis` It is of major economic importance because the milky latex extracted from the tree is the primary source of natural rubber.

In the wild, the tree can reach a height of up to 100 feet (30 m). The white or yellow latex occurs in latex vessels in the bark, mostly outside the phloem. These vessels spiral up the tree in a right-handed helix which forms an angle of about 30 degrees with the horizontal, and can grow as high as 45 ft. In plantations, the trees are generally smaller for two reasons:
1) Trees grow slower when they are tapped for latex, and
2) trees are generally cut after 30 years because latex production declines as trees age, and they are no longer economically viable. The tree requires a tropical or subtropical climate with a minimum of about 1200 mm/yr of rainfall, and without frost.If frost does occur, the results can be disastrous for production. One frost can cause the rubber from an entire plantation to become brittle and break once it has been refined

Harvest of Latex
Harvesters make incisions across the latex vessels, just deep enough to tap the vessels without harming the tree's growth, and the latex is collected in small buckets. This process is known as rubber tapping. Latex production is highly variable from tree to tree and across clone types.
The Pará rubber tree initially grew only in the Amazon Rainforest. Increasing demand and the discovery of the vulcanization procedure in 1839 led to the rubber boom in that region, enriching the cities of Belém and Manaus. The name of the tree derives from Pará, the second-largest Brazilian state, the capital of which is Belém. These trees were used to obtain rubber by the natives who inhabited its geographical distribution.
The Olmec people of Mesoamerica extracted and produced similar forms of primitive rubber from analogous latex-producing trees such as Castilla elastica as early as 3600 years ago.The rubber was used, among other things, to make the balls used in the Mesoamerican ballgame.
Early attempts were made in 1873 to grow H. brasilensis outside Brazil. After some effort, 12 seedlings were germinated at the Royal Botanic Gardens, Kew. These were sent to India for cultivation, but died.
A second attempt was then made, some 70,000 seeds being smuggled to Kew in 1875, by Henry Wickham, at the service of the British Empire.About 4% of these germinated, and in 1876, about 2000 seedlings were sent, in Wardian cases, to Ceylon (modern day Sri Lanka) and 22 were sent to the Botanic Gardens in Singapore.
Once established outside its native country, rubber was extensively propagated in the British colonies. Rubber trees were brought to the botanical gardens at Buitenzorg, Java, in 1883.By 1898, a rubber plantation had been established in Malaya,
and today, most rubber tree plantations are in South and Southeast Asia, with some also in tropical West Africa. Efforts to cultivate the tree in South America (Amazon) were unsatisfactory because of blight.The blight, called South American leaf blight, is caused by the Ascomycota, Microcyclus ulei.
