Rubber latex is extracted from rubber trees. The economic life of rubber trees in plantations is around 32 years, with up to 7 years being an immature phase and about 25 years of productive phase. The soil requirement is well-drained, weathered soil consisting of laterite, lateritic types, sedimentary types, nonlateritic red or alluvial soils.
Hevea brasiliensis, the Pará rubber tree, sharinga tree, seringueira, or most commonly, rubber tree or rubber plant, is a flowering plant belonging to the spurge family, Euphorbiaceae, originally native to the Amazon basin, but is now pantropical in distribution due to introductions.
In the wild, the rubber trees grow apart from each other as a protection mechanism against plagues and diseases, often growing close to bigger trees of other species for added support. In Fordlândia, however, the trees were planted close together in plantations, easy prey for tree blight, Saúva ants, lace bugs, red spiders, and leaf caterpillars.
The tree species used in a plantation are also an important factor. Where non-native varieties or species are grown, few native faunas are adapted to exploit these, and further biodiversity loss occurs. However, even non-native tree species may serve as corridors for wildlife and act as a buffer for native forests, reducing edge effect.
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]

Hevea is a genus of flowering plants in the spurge family, Euphorbiaceae, with about ten members. It is also one of many names used commercially for the wood of the most economically important rubber tree, H. brasiliensis. The genus is native to tropical South America but is widely cultivated in other tropical countries and naturalized in ...
In 1924 Morris bought some young rubber trees from the Firestone plantation at Harbel. After they were successfully planted at the family homestead near Monrovia, a family rubber farm soon started to expand. [6] After her husband died in 1935, her eldest son Harry L. Morris returned to Liberia to help carry on the farm. [7]
