The holistic sustainability practiced at Bartinney is about more than preserving the natural environment, it includes the biosphere of Banhoek Valley as a whole, cultural and historical heritage.

More than 7000 trees have been planted and fynbos endemic to the area re-established on 17 hectares of rehabilitated land from what was previously a pine and gum plantation. Rose started her own nursery growing indigenous fynbos to restore and protect the neglected slopes. Interventions are carried out in line with the ecological systems of the valley. The new plantings of fynbos form an ecological corridor that runs from the lofty Botmaskop down to the Zevenrivieren River.

Biological pest control rather than pesticides are used and no herbicide has been sprayed in 8 years. That, together with the planting of fynbos corridors from mountain to river has brought back the birds in abundance and the porcupines and rooikatte (lynx) too. A resident cape silver fox, honey badger pair and two leopards have been captured on the mountain camera. A buffer zone of proteas between the vineyards and the mountain discourages local baboons from raiding the grapes. Birds and animals aren’t all that came back. When the final blue gum above the house was felled, a spring that hadn’t flowed in 40 years began to flow again.

Bartinney is Carbon Neutral. This means that a zero carbon footprint in both farming and wine making has been achieved. 50% of Bartinney’s power is generated through solar. The farm has had Champion status in the Biodiversity and Wine Initiative (BWI) since September 2010 and is a member of WIETA (Agricultural Ethical Trade Initiative). Rose is a founding member and Trustee of the Banhoek Conservancy, whose goal is for the social upliftment of the poorer communities in Banhoek and environmental improvement of the natural areas of the greater Banhoek Valley.
