Indigenous insect species are encouraged, to provide a balanced ecology where predatory insects (below) help to keep insect pest populations under control. Similarly, an extensive planting program of local tree species has been undertaken to provide habitats for native birds, which tend to exclude exotic birds which may damage crops.
As well as providing grapes with better colour and flavour, the trellis systems employed and the resulting vine canopy structures obtained assist in reducing the incidence of mildews and other fungal diseases in the vineyard. This allows fungal diseases to be more easily controlled than with organic sprays alone.
