On new projects, well-marked conservation areas are set aside in areas designated as having ‘high conservation value’ status. Ongoing programmes of planting jungle trees and other plants are undertaken. Areas alongside river banks are set aside as conservation areas both to prevent leaching of fertilisers into water courses and to provide wildlife corridors.
The Group has more than 2,000 hectares of conservation areas, which are regularly monitored by sustainability teams resident on its estates. It has a ‘zero waste’ approach.
New planting procedure ('NPP') documents have been routinely lodged with the RSPO Secretariat in a timely manner and are available on the RSPO website. All new plantings carried out since the beginning of 2015 have been covered by an high conservation value ("HCV") and high carbon stock ("HCS") assessment.
In respect of agronomic management, leguminous cover crops are planted to fix nitrogen in the soil, prevent erosion and provide nutritious leaf litter. In areas with slopes above 12%, contour terraces are dug. This prevents soil erosion and retains water for palms on the terraces. Slopes of more than 25% are not planted.
The Group uses integrated pest management to control pests on its plantations. Beneficial host plants are planted alongside estate roads to attract predators (insects) of leaf pests. The predators feed on leaf pest larvae thus reducing the need for chemical spraying. Where possible, barn owls are bred and introduced to control rats, minimising the need for chemical baits.
