PRINCIPAL MANAGEMENT DIRECTIONS 1. POLICIES AND GOALS Policies This Plan is based on CALM policies current at the time of publication. These policies are developed from legislation, principally the CALM Act (1984) and associated regulations. Policies are published and distributed throughout CALM as policy statements. They are available to the public on request. The Plan is also consistent with NPNCA policies. Goals The Plan outlines the goals, objectives, and strategies for the management of Dryandra for the next ten years. Based on the recognition that nature conservation is the highest priority, the following management goals for Dryandra are proposed: • Conserve biological, physical, cultural and landscape values. • Facilitate public enjoyment of Dryandra in a manner compatible with the conservation goal. • Manage commercial uses in a manner that minimises the impact on other values. Management Context Dryandra is situated between the 500 mm. and 600 mm isohyets, receiving significantly less rainfall than the Darling Range to the west. The structure and composition of the vegetation reflects this: forests of Jarrah (Eucalyptus marginata) have been replaced by woodlands with a more open canopy, typically comprising Wandoo (E. wandoo) and Powderbark Wandoo (E. accedens). In recognising this fundamental difference, management principles within this Plan are more closely aligned to those of other woodland communities within the wheatbelt than the Darling Range forests. Land clearing in the wheatbelt has reduced the area of native bushland to isolated remnants. In the Dryandra area, clearing has been comparatively recent, mainly occurring in the last forty years (see Map 2). As late as 1962, Dryandra was connected to the main forest belt of the Darling Range, and other large areas of native bush existed to the east. With the continued clearing of private property, the blocks of Dryandra have eventually become separated from these other areas and each other. The impacts associated with habitat fragmentation are still likely to be affecting the biota of Dryandra. For example, Saunders (1989), predicts further losses of bird species from wheatbelt reserves, depending on the extent of removal of native vegetation and the length of time since clearing occurred. Despite Dryandra's overall large size in comparison with other reserves of the central western wheatbelt, it is subject to similar problems to those of other fragmented areas of native vegetation. These include: • susceptibility to hydrological changes; 1
• inward drift of fertilisers and weeds from agricultural land; • restrictions on fauna movement; and • vulnerability to single catastrophic events, such as a wildfire that burns a large proportion of a block. Re-colonisation by plants and animals may be very slow, or may not occur at all. Such events could therefore lead to local extinctions. The continued survival of Dryandra's flora and fauna is dependent not only on the protection of CALM-managed land, but also on the partial revegetation of the surrounding farmland. A primary value of Dryandra is its role in conserving a representative sample of the plants and animals of the central western wheatbelt. The area also makes an important contribution to maintaining biodiversity on an international scale by providing habitat for seven threatened species of fauna. In recognition of these attributes part of Dryandra Woodland is listed by the Australian Heritage Commission on the Register of the National Estate. Overall, Dryandra Woodland has the potential to cater for a range of land uses, including nature conservation, recreation, education, timber production and Aboriginal cultural activities. These uses, together with its location within cleared farmland, provide opportunities to demonstrate how the integration of management across crown land and private property boundaries can contribute to ecologically sustainable land-use. 2. LAND TENURE BACKGROUND Current Tenure Dryandra Woodland refers to State forests 51 (Lol Gray), 52 (Highbury), and 53 (Montague): they have a combined area of 28 066 ha and are vested in the Lands and Forest Commission for the purpose of multiple use. Conservation of flora and fauna is currently the primary use, with mallet timber production and recreation as secondary uses. State forest 52 lies south of Narrogin, while State forests 51 and 53 (formerly known as 'Dryandra forest') are both north of Narrogin. 2
