carried out to ensure the persistence of hollow-using species include protecting old growth jarrah forest and keeping extensive areas of forest reserved from logging. In the sections of jarrah forest are available to timber harvesting, science-based prescriptions have been implemented delegating those trees that are to be retained. Protected areas 12.86% of the ecoregion is in protected areas. Protected areas are managed for uses including recreation and conservation. There are many small areas of parkland, and larger protected areas include the Dryandra Woodland and the Perup Forest Ecology Centre. The Walpole Wilderness Area, which was established in 2004, includes several national parks that cover a portion of the southern Jarrah Forest and the Jarrah-Karri forest and shrublands to the south. Lane Poole Reserve is the largest reserve in the Northern Jarrah Forest. There are few large and secure reserves such as national parks and nature reserves in the northern jarrah region where the best forest occurs. Much of this region is under long-term mining leases for bauxite owned by Alcoa and Worsley who have actively resisted attempts to allow the WA government to create substantial and secure reserves. Protected areas include: Avon Valley National Park Beelu National Park Blackwood River National Park Boyndaminup National Park Bramley National Park Dalgarup National Park Dryandra Woodland National Park Easter National Park Gooseberry Hill National Park Greater Kingston National Park Greater Preston National Park Greenmount National Park Hassell National Park Helena National Park Hilliger National Park John Forrest National Park Kalamunda National Park Korung National Park Lake Muir National Park Lake Muir Nature Reserve Lane Poole Reserve Lesmurdie Falls National Park Midgegooroo National Park Milyeannup National Park Mount Frankland North National Park Mount Lindesay National Park Mount Roe National Park Porongurup National Park Serpentine National Park Shannon National Park Stirling Range National Park Wandoo National Park Walyunga National Park Waychinicup National Park Wellington National Park Whicher National Park Wiltshire-Butler National Park Yelverton National Park Benefits of protection Unlogged buffers and old growth forest contain high densities of trees with appropriate hollows for roosting, where gap release and shelterwood areas do not. Mature forest is essential to the development of tree hollows and the prescribed retention of the largest trees will significantly improve the chances of large species such as the red-tailed black cockatoo and the common brushtail possum inhibiting appropriately sized tree hollows. The implementation of the fox baiting program was expected to greatly
