The TLC is a registered environmental organisation that raises funds from the public to protect irreplaceable sites, endangered species' habitats, and rare ecosystems by buying and managing private land. In 2010/2011, the Purves Environmental Fund contributed funds toward the biggest private conservation deal in Australia's history with acquisition of Skullbone Plains. Skullbone is a 1,618 ha highland property less than 10 km from Lake St Clair, adjacent to the Lake St Clair/Cradle Mountain National Park. Some 16 km of the property boundary abuts the World Heritage Area, with which it shares substantial conservation values including nationally listed Sphagnum bogs, eight nationally listed threatened species, State listed vegetation communities, and a further 12 State listed threatened species.
The Fund supported WWF to raise awareness of the terrible plight facing Tasmania's World Heritage listed Macquarie Island. The island's unique and fragile ecosystems are under extreme threat from rodents and urgent action is needed to resolve the issues. The Fund's support gave WWF additional communications and organisational capacity to increase the effectiveness of their Macquarie Island public awareness and community education outreach activities. Partly as a result of WWF's efforts, a tremendous outcome was achieved. In early June 2007 the Australian and Tasmanian Governments announced that they had reached an agreement to jointly fund the eradication of rodent pests on Macquarie Island to protect its World Heritage values.
