Natural windbreaks or vertical windbreaks along boundaries protecting bird net structures are recommended. In a new vineyard, incorporate bird netting and windbreak material into a bird exclosure. Bird exclosures must enclose the entire vineyard. A bird exclosure consists of bird netting suspended on cables over the grapevine canopy. The roof must be high enough above the canopy so the vines don't grow through the netting.
Several companies specialise in designing, building and supplying the materials for exclosures.
Several types of bird net are available. Some are designed to lie directly over the top of vines. This sort is unsuitable for table grape production because of reduced access to the crop. Use UV-stabilised knitted monofilament material. The colour of the material is unimportant.
