BWI has already earmarked 50,000ha for conservation in the Cape during the past two-and-a-half years. The area that is set aside cannot be cultivated for agricultural use.
BWI was set up in 2004 as South Africa's botanical region, the Cape - where nearly 95 per cent of wine growing takes place, came under increased threat from agriculture, urban development and invasive alien species.
Inge Kotzé, BWI project coordinator, said:
"We are enormously encouraged by the enthusiastic backing from the wine industry. Growers are farming in ways that are more in harmony with nature and the environment." BWI is co-hosting a conference, Vinecology: understanding the management of biodiversity within vineyard landscapes, at the end of June.
