Rubber requires no permanent shade, and indeed few trees would be tall enough to afford it The protection of dadaps, as already described, is often valuable in the early stages of growth, and this is specially the case in wind-swept situations. The interplanted dadaps afford an excellent protection from the wind, but they should not be allowed to top the rubber for too long a period. Dadaps or similar trees may also be grown conveniently in belts across the direction of the prevailing winds in cases where interplanting is considered undesirable. They may also be introduced where a low growing intercrop has been planted which affords no protection.
