Goobang

Goobang National Park is a significant woodland protected area in the central western slopes of New South Wales, located approximately 30 kilometres east of Parkes. Covering approximately 27,200 hectares, the park protects outstanding examples of the box-ironbark woodland and western slopes eucalypt communities that once extended across much of the central west but have been heavily cleared for wheat farming and grazing. The park is particularly important as habitat for the critically endangered regent honeyeater and the endangered swift parrot, and forms part of a network of woodland reserves on the central western slopes.

Goobang National Park is of national significance for threatened woodland birds. The critically endangered regent honeyeater visits the park's box-ironbark woodland during flowering events. The endangered swift parrot winters in the ironbark woodland, feeding on nectar. Superb parrots and turquoise parrots are resident. Diamond firetails, speckled warblers, and brown treecreepers represent the threatened small woodland bird community. Eastern grey kangaroos and wallaroos are abundant. Koalas have been recorded in the park's box woodland communities. The park's inland location makes it important for species characteristic of the drier western slopes woodland.

The box-ironbark woodland communities of Goobang are outstanding examples of the vegetation type that formerly dominated the central western slopes. Yellow box, grey box, and orange box are the dominant eucalypts on the deeper soils of the valley floors and lower slopes. Red ironbark and mugga ironbark occur on the drier, rockier sites. Bimble box and white box are present on the more arid western sections. The woodland understorey includes golden wattles, silver wattles, native grasses, and diverse geophytes. The flowering sequence of the box and ironbark species provides year-round nectar resources for the honeyeater community.

Goobang National Park is underlain by Silurian volcanic and sedimentary rocks of the Lachlan Fold Belt, with intrusive igneous rocks forming some of the rocky hill country within the park. The rolling terrain reflects the differential erosion of the varied volcanic and sedimentary basement. The ironbark woodland occurs preferentially on the rocky, shallow soils derived from volcanic rocks, while box woodland occupies the deeper, more fertile soils of the valleys. The central western slopes soils are generally more fertile than the sandstone soils of the eastern tablelands, supporting more productive woodland communities.

Goobang National Park has a semi-arid continental climate typical of the central western slopes. Summers are hot, with temperatures regularly exceeding 38°C, and heatwaves are a regular summer feature. Annual rainfall averages approximately 550 millimetres, with high variability between years. The flowering intensity of the box and ironbark trees, and therefore the food resources available for honeyeaters, is closely linked to rainfall patterns. Winters are cool, with overnight frosts common from June to August. Spring is the most pleasant and botanically productive season.

The Wiradjuri people are the traditional custodians of the Parkes region and the central western slopes, with the box-ironbark woodland providing honey, game, and plant foods in an environment that supported substantial human populations. European pastoralists arrived in the area from the 1820s and 1830s, establishing large sheep and cattle stations. The discovery of gold at Forbes in 1861 brought a wave of immigrants to the central west, and the subsequent wheat farming expansion substantially cleared the woodland across the slopes.

Goobang National Park was gazetted in 1999, recognising the outstanding biodiversity values of the box-ironbark woodland and the importance of protecting habitat for the regent honeyeater and other threatened woodland birds. The park was created from former state forest and Crown land. Management has focused on invasive weed control, feral animal management, and coordinating with private landowners on landscape-scale habitat management for threatened woodland birds. Research programs monitoring regent honeyeater use of the park have provided important data for the national recovery program.

Goobang National Park is renowned among birdwatchers for its populations of threatened woodland birds, including the critically endangered regent honeyeater. Walking tracks through the diverse woodland habitats provide excellent birdwatching opportunities. Wildflower displays in spring and early summer, when the box trees are in flower, can be spectacular. The open woodland character of the park provides excellent visibility for wildlife observation and photography. The park is less well-known than Capertee Valley to the east but holds equally significant woodland bird populations.

Goobang National Park is accessed from Parkes via unsealed roads, approximately 30 kilometres to the east. A day use picnic area is available. There are no campgrounds. Parkes provides comprehensive visitor services. The park is approximately 350 kilometres from Sydney via the Great Western Highway through Orange. A national parks pass applies. The best visiting times for regent honeyeater observation are during box tree flowering events, which vary seasonally.

The regent honeyeater recovery program is the defining conservation priority at Goobang, with management actions focused on maintaining and improving the quality of box-ironbark woodland habitat. Invasive weeds, particularly serrated tussock and other exotic grasses, are managed to maintain the native grass understorey structure required by ground-foraging woodland birds. Feral goat and rabbit control reduces grazing pressure on native vegetation. Coordination with private landowners in the surrounding landscape is crucial, as the park alone is insufficient to support viable regent honeyeater populations.
