Statement of Management Intent Mother of Ducks Lagoon Nature Reserve 1. Introduction This statement outlines the main values, issues, management directions and priorities of the National Parks and Wildlife Service (NPWS) for managing Mother of Ducks Lagoon Nature Reserve. This statement, together with relevant NPWS policies, will guide the management of the reserve until a plan of management has been prepared in accordance with the National Parks and Wildlife Act 1974 (NPW Act). The NPWS Managing Parks Prior to Plan of Management Policy states that parks and reserves without a plan of management are to be managed in a manner consistent with the intent of the NPW Act and the ‘precautionary principle’ (see Principle 15). 2. Management principles Nature reserves are reserved under the NPW Act to protect and conserve areas containing outstanding, unique or representative ecosystems, species, communities or natural phenomena. Under the NPW Act (section 30J), nature reserves are managed to: • conserve biodiversity, maintain ecosystem functions, and protect geological and geomorphological features and natural phenomena • conserve places, objects, features and landscapes of cultural value • promote public appreciation, enjoyment and understanding of the reserve’s natural and cultural values • provide for appropriate research and monitoring. The primary purpose of nature reserves is to conserve nature. Nature reserves differ from national parks in that they do not have the provision of visitor use as a management purpose or principle. 3. Context Reservation details: Mother of Ducks Lagoon Nature Reserve was reserved in 1973, with further additions made to the reserve in 2005, 2010 and 2011. Size: 194 hectares. Mother of Ducks Lagoon Nature Reserve is located 38 kilometres north of Armidale and adjoins the township of Guyra on the northern tablelands of New South Wales. It is located in the New England Tablelands Bioregion and within the administrative areas of Guyra Local Aboriginal Land Council, Northern Tablelands Local Land Services and Guyra Shire Council.

Located in the flat upper valley of Laura Creek and bounded by the Great Dividing Range to the east and south, water draining from the lagoon flows into the Gwydir River, 53 kilometres to the west and then onto the Murray–Darling system. The lagoon is one of 57 natural temporary freshwater wetlands on the New England Tablelands, and one of only three within NPWS estate. The lagoon has a small catchment and is referred to as a watershed wetland. Although once considered permanent water, the lagoon is ephemeral and subject to an irregular cycle of drying and wetting. These wetlands support a variety of native plant species for both wet and dry conditions and have generally low numbers of introduced plant species. Waterbird habitat within the reserve is dominated by areas of grassy meadow and swamps that are intermittently inundated by shallow water, with small areas of more permanent, deeper open water. Over 87 species of water and terrestrial birds have been observed in and around the reserve. Birdwatching is the main attraction for visitors to this reserve. 4. Values • Uniquely amongst the New England Tableland lagoons, the bed of Mother of Ducks Lagoon has a relatively deep (300 to 500 mm) formation of peaty soils supporting an extremely dense and varied assemblage of native aquatic plant species.

• The wetlands of this reserve are consistent with the Upland Wetlands of the Drainage Divide of the New England Tableland Bioregion (Upland Wetlands), an endangered ecological community listed under the NSW Threatened Species Conservation Act 1995 (TSC Act). The wetlands are also considered likely to conform to the definition of the Upland Wetlands of the New England Tablelands and the Monaro Plateau endangered ecological community listed under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). • The reserve provides habitat for two threatened plant species: bluegrass (Dichanthium setosum) and the small snake orchid (Diuris pedunculata), which are listed as vulnerable and endangered, respectively, under both the TSC and EPBC Acts. • The reserve provides a wide variety of habitats for both water and terrestrial birds, as well as for amphibians, reptiles and some mammals. Fifteen of the bird species are listed as vulnerable or endangered under the TSC Act. Among these, the Australian painted snipe (Rostratula australis) is also of national concern and listed under the EPBC Act. Eight species recorded for this reserve are also identified under a range of international agreements on migratory birds. • The Booroolong frog (Litoria booroolongensis), listed as endangered under both the TSC Act and EPBC Act, also resides within the reserve. • As an area of unusual hydrological and biotic interest and the site of significant resident, endemic/nomadic and international migratory bird populations, the reserve offers considerable potential for future research and educational opportunities. • There are no known Aboriginal sites within the reserve, although there are a number of recorded sites in the vicinity. • The lagoons and surrounding lands have been subject to a history of cattle grazing, recreation and changes to the hydrology of the lagoon. Grazing rights were revoked in 1978, and in 1987 a levee bank was constructed with the aim of restoring the water body to a more natural state. No historic heritage sites have been identified in the reserve. • Visitor use of the reserve is variable and often dependant on the abundance of bird life using the lagoon at the time. Visitor facilities within the reserve consist of a bird observation platform located over the lagoon and associated interpretive signage. • Council facilities adjacent to and associated with the reserve include a picnic shelter, picnic tables, a walking track to the bird observation platform including footbridges over wetter areas, an information structure and a carpark. Walking access is limited to the track between the carpark and the platform, and current visitation is centred on birdwatching. No camping or fires are permitted. There is no public vehicle access to the reserve. 5. Issues • The greatest threat to these wetlands is the alteration of their natural water regime. The lagoon’s water regime has been highly modified by past uses and the levee bank. In its current state the reserve provides two unique variants on the Upland Wetlands endangered ecological communities, with both intermittent and ephemeral ecosystems being able to occur at the same time. It is for this reason that maintenance of the levee bank and the water regime are important and will be continued in conjunction with Guyra Shire Council and Guyra Golf Club. • Wetlands such as Mother of Ducks Lagoon were cleared, and in some cases drained, by the early settlers to improve grazing potential. As a result, there is little, if any of the Page 3 Statement of Management Intent: Mother of Ducks Lagoon Nature Reserve
original natural timber left growing in or around the reserve. Grazing by domestic stock, and pest and weed intrusions are also threats to this community. • Foxes (Vulpes vulpes) and rabbits (Oryctolagus cuniculus) have colonised the levee bank. Foxes prey heavily on birds within the reserve, and in drier times may access the centre of the levied lagoon and impact upon ground-dwelling birds at peak nesting times. Both these species are listed as key threatening processes under the TSC Act and the fox is subject to a threat abatement plan. It is expected, due to the proximity of Guyra, that cats may also occur within or frequent the reserve. • Goldfish (Carassius auratus) are present within the lagoon, and at high densities may compete with waterbirds for invertebrate food resources. The plague minnow or mosquito fish (Gambusia holbrooki) is also present and is listed as a key threatening process under the TSC Act. • Five weed species have been identified as a priority for control in the reserve: Bathurst burr (Xanthium spinosum), spear thistle (Cirsium vulgare), nodding thistle (Carduus nutans), Noogoora burr (Xanthium occidentale) and St John’s wort (Hypericum perforatum). Isolated occurrences of blackberry (Rubus fruticosus agg.) and willow (Salix spp.) are also present in the reserve. 6. Key management directions • Fire is managed in accordance with the Mother of Ducks Lagoon Nature Reserve Fire Management Strategy. • Pest management programs will be implemented in accordance with the NPWS Regional Pest Management Strategy: Northern Tablelands Region. • Further draining or damming of the endangered ecological community will be prevented. • Stock intrusions into the reserve will continue to be controlled in cooperation with neighbours. Subject to available resourcing, assistance may be provided to neighbours to install stock-proof park boundary fencing in accordance with the NPWS Boundary Fencing Policy. • All management activities will be preceded by the preparation of an environmental assessment or heritage assessment where this is a requirement of NPWS policy or legislation. • Environmental repair and threat management programs, such as erosion mitigation measures, pest management, and activities arising from threatened species requirements may be implemented in accordance with NPWS policies and procedures. • Non-intrusive works may be undertaken where necessary to protect cultural heritage items from further deterioration, to ensure the safety of visitors and wildlife or to prevent damage to park assets. • A plan of management will be prepared to set out the ongoing management objectives for the reserve. The plan of management is a statutory document under the NPW Act which will be available for public comment. NPWS will also encourage the community to contribute to the ongoing conservation of the reserve by promoting and raising public awareness of its special values.
