Introduction I 1.1 The principal geological resources of the Taree area are non-metalliferous sedimentary deposits which have a variety of uses principally in the I construction industry. Igneous or metamorphic deposits are of less significance based on present knowledge. Deposits of heavy mineral sands I occur along the coastline, although most of their potential has already i been realised. 1.2 The non-metalliferous deposits consist of limestone, construction sand, I gravel, structural clay/shale, road base and fill, and possibly peat.
1.3 There are no known unusual geological hazards in the area. Coastal erosion of the beach/dune complex and flooding of the Manning River tidal delta are recurring hazards, while poor soil permeability and relatively high rainfall contribute to liquid waste disposal problems in many areas.
The known geological resources are shown on Map 2.
1.4 This section is based on information supplied by the Department of Mineral Resources.
I Heavy Mineral Sands
1.5 Deposits of heavy mineral sands occur in the sandy Quaternary barrier and backbarrier sediments along the coastline of the study area. However, most of the economically significant concentrations have previously been mined, and there is apparently only limited potential for further extraction.
1.6 Mining titles/applications for heavy mineral sands affect all the coastal parishes within the study area; the parishes are (from north to south) Harrington, Oxley, Bohnock, Beryan, and Tuncurry. Of the current leases within the study area only SpL 410, Parish Tuncurry on the southern
I R Travers Morgan Pty Ltd boundary of the study area, and ML 466 (1973) and PL 477, Parish Bohnock have potential for economic recovery of heavy mineral sand in the I foreseeable future.
1.7 Economically significant concentrations of heavy minerals occur within Old Bar Park and Portion 12, Parish Bohnock at the southern entrance to the Manning River (See Map 2 ). Although not currently held under title, this deposit is considered by the Department of Mineral Resources to have potential for future economic extraction, and should not be sterilised by / other incompatible land uses until the deposit has been worked.
1.8 Significant concentrations of heavy minerals have been identified behind Black Head Beach. Title over this area was relinquished by the holder because of the small size of the deposit and the environmentally sensitive nature of the site. Future recovery of this deposit appears to be unlikely.
1.9 According to the Department of Mineral Resources there is little potential for the discovery of further heavy mineral deposits of economic grade in the study area.
Limestone
1.10 There are a number of extensive limestone deposits within the study area west of Taree (refer to Map 2 ). Some of these deposits have been worked in the past and some have potential for further extraction. The limestone is used principally as a metallurgical flux and as an agricultural soil improver, although one quarry is capable of producing high quality massive limestone, presumably suitable for decorative stone as cladding/facades on buildings.
Cedar Party Limestone
1.11 The most important limestone deposits are those within the Cedar Party Limestone formation, The principal outcrops of this formation occur between Taree and Wingham and immediately to the north. I R Travers Morgan Pty Ltd ' 1.12 Two exposures of this formation occur partly within an area in the vicinity of Kolodong which is currently being investigated by Council as a possible site for urban expansion of Taree.
I 1.13 The Cedar Party Limestone deposits have been worked at a number of sites in the past but the exact extent, quality, amount of overburden and depth of deposit have not been investigated in any detail. The limited information available does apparently suggest that the deposits have I significant economic potential and warrant further investigation. A major advantage of this formation is fts location close to major I population centres and transport facilities.
1.14 It is recommended that the potential of the Cedar Party Limestone be clearly established by the Department of Mineral Resources as soon as possible and, in the meantime, no action be taken by the Council to 1 sterilise this resource or unduly restrict future extraction. It seems apparent that the extent of the formation is great enough to provide I adequate reserves and also allow rural subdivision as well as urban expansion over portions of the deposit. The important matter is to I determine the most environmentally sound and economically viable locations for extraction of suitable material prior to the establishment of other incompatible land uses.
1.15 Further information on the three most significant deposits within this formation is provided below. This information is taken from a report by I the Department of Mineral Resources. I Locality 1 1.16 This deposit is poorly exposed but has been traced over a distance of I about 8 km. It is estimated to be about 130 m thick on average with a maximum thickness of about 700 m.
I 1.17 The limestone has been quarried at a number of places in the past, most notably at Western's Quarry near the Wingham Rifle Range, for use in the I steel-making industry in Newcastle. Significant tonnages of extractable I I I R Travers Morgan Pty Ltd material remain, particularly in the vicinity of Western's Quarry where I massive, high quality limestone is present. I Locality 2 1.18 This deposit can be traced over a distance of almost 8 km in a I northwesterly direction from near Taree to Cedar Party Creek, along the Cedar Party - Taree Road. It comprises a sequence of limestone and I intercalated sediments up to 130 m thick which dips steeply to the northeast.
[ 1.19 Outcrop is poor and it has been suggested by some workers that the limestone is not continuous but consists in fact of a number of discrete LI pods.
I 1.20 Numerous quarries have been developed within this deposit in the past, I mainly for agricultural limestone and metallurgical flux. 1.21 The deposit has considerable potential for further extraction of high LI quality limestone.
Locality 3 LI
1.22 This deposit, which extends over a distance of about 5 km, occurs within a sequence of fine grained sandstone, and lenses out in a northwesterly direction.In places the unit consists of four distinct beds of limestone separated by lenticular intercalated sediments.
I 1.23 The deposit has been quarried in a number of places. The larger quarries were operated by the Broken Hill Proprietary Company which produced about I 120,000 t of stone for use as a metallurgical flux. Moderate reserves remain in the deposit. The southeastern-most part of the deposit has I already been largely sterilized by urban development. I I I Li R Travers Morgan Pty Ltd Other Limestone Deposits I 1.24 A number of small or poor quality limestone deposits occur to the southwest of Wingham in the Killawarra, Kimbriki and Hillville areas (see I Map 2 ). The limestone in these deposits is generally variable and impure in composition and frequently contains interbedded sediments. I Consequently, the deposits are considered to have little potential for I future extraction. Construction Materials I 1.25 There is little detailed information on construction material resources within the study area and, apart from existing extraction sites, it is not I possible to identify additional specific areas which have significant I potential for extraction. I Construction Sand 1.26 Deposits of sand suitable for construction purposes occur within stream I channels and Quaternary floodplain deposits, and in the Quaternary barrier, backbarrier and estuarine deposits along the coast.
I 1.27 Substantial quantities of medium to coarse grained river sand (and gravel) are dredged from the Manning River at Taree Estate by Readymix-Farley Pty I Ltd. Small quantities of fine-medium grained sand are extracted from a coastal barrier (dune) deposit about 3 km south of Old Bar (precise I location not known). 1 1.28 Extensive deposits of predominantly medium to coarse grained river sand and gravel occur within the Manning River (extending at least as far downstream as Taree) and in its associated floodplain deposits within the Lj alluvial sediments occurring along some of the other streams in the area H such as Cedar Party Creek and Dingo Creek. [I -J
1.29 The coastal sediments within the area appear to offer only limited I potential for future extraction, primarily because of the generally small I I 1 R Travers Morgan Pty Ltd size of the coastal barrier deposits which are the main potential sand I source.
1.30 Only one significant section of Quaternary alluvium has been highlighted by the Department of Mineral Resources and therefore shown on Map 2. Itis suggested that many other suitable deposits could be located on the Manning River floodplain.
I Coarse Aggregate
1.31 Gravel deposits within the Manning River are the major source of coarse aggregate for the Taree area. Large amounts of gravel (over 140,000 tonnes in 1980-81) are dredged annually from the river at Taree Estate by I Readymix-Farley Pty Ltd.
1.32 Extensive deposits of gravel occur within the Manning River above Taree and there is good potential for the occurrence of economically significant l gravel deposits beneath the adjacent floodplains. Deposits of gravel also occur along other streams in the area. Older high level gravel deposits I near the Manning River between Wingham and Kolodong may have some potential as a source of coarse aggregate (see Map 2 ). The high level gravels at Kolodong lie largely within the area currently being I investigated by Council for future urban development. It is recommended that this gravel deposit be thoroughly evaluated so that development may I proceed around it.
Hardrock Aggregate and Stone
1.33 There appears to be only limited potential for extraction of high quality hard rock aggregate within the study area. The Tertiary alkaline intrusives north of Wingham (see Map 2 ) have been identified as I having potential for extraction of stone and aggregate.
1.34 The Department of Mineral Resources undertook a survey in 1969 to identify potential backwater quarry sites for use in the coastal zone between I Hallidays Point and Crowdy Head and extending inland to Wingham. Eleven I I I R Travers Morgan Pty Ltd sites were identified as capable of providing large rip rap stone, I including the two alkaline intrusives mentioned in the previous paragraph.
1.35 It is our recommendation that site 6, near Purfleet and shown on Map 2 be carefully evaluated as the preferred site for such extraction. It is near the end use of the product, reducing transport costs; there is access I to the back of the site via an unsealed road which would prevent visual intrusion to motorists on the Old Bar Road. Many of the other sites are I environmentally sensitive because of their visual character (e.g. sites 1, 2, 3, 11) or are reasonably far removed from the point of use.
1.36 It is recommended that site 6 or some other preferred site be conserved I for use as a stone/aggregate quarry.
Unprocessed Construction Materials I
1.37 These are materials which are used in their extracted form without any I significant processing, chiefly for roadmaking and filling by government and local government bodies. They include such materials as weathered I rock, ridge gravel, soil and loam.
1.38 Materials suitable for use as unprocessed construction materials occur widely throughout the area and because of their general availability and low value, proximity to the point of use is a major factor in locating I sources of such materials.
Metallic Minerals
1 1.39 Three minor metalliferous mineral occurrences are known in the study area (see Map 2 )
i) Fine gold occurring sparsely in bench gravel beside the Manning River just upstream from Killawarra Ridge; I ii A small gold lode deposit occurring in Devonian basalt. (This deposit produced a minor amount of gold in the 1930's); and I iii) A reported silver occurrence, also within Deionian basalt.
I
I I R Travers Morgan Pty Ltd 1.40 None of these deposits are considered to be economically important; I however, geological knowledge of the area in regard to metalliferous mineral resources is poor and in view of the large area involved, I sufficient flexibility should be incorporated in any future zoning of the area to enable mineral exploration to continue.
I 1.41 At this time, the most prospective part of the subject area for metalliferous mineralization is an area of Devonian basalt and Permian [ serpentinite occurring around Mt Kiwarrak (see Map 2 ).
I Structural Clay/Shale I 1.42 Clay/shale is currently extracted from three sites within the area for use in brick manufacture at A J Baker's Lincoln Brickworks at Wingharn. One of the sites is adjacent to the brickworks, the others are at Karaak Flat and I Cedar Party respectively (see Map 2 ). Total production in 1980-81 I was 16,335 tonnes. 1.43 Little is known geologically about any of the deposits; however, all three I occur within the Giro Beds which consist predominantly of pebbly mudstone, mudstone, conglomerate, siltstone, shale and sandstone. I 1.44 There is potential for the discovery of other clay/shale deposits within the finer grained sediment of the Giro Beds, and other stratigraphic units I which crop out in the area, but because of the lack of information it is I not possible to identify specific areas with potential for extraction. Peat I 1.45 There is some potential for the occurrence of economically significant I peat deposits in the Frogalla Swamp and other coastal swamps although the Department of Mineral Resources has no detailed information on the I occurrence of peat in this area. I [1 1 1 R Travers Morgan Pty Ltd Geological Hazards
I 1.46 The coastal margin of the study area is subject to the hazard of coastal erosion, while some of the inland areas are subject to risk of flooding or I landslip or other environmental hazards.
Coastal Erosion
I 1.47 Lands prone to coastal erosion (both shoreline retreat and inland moving sand dunes), essentially comprise the zone up to 200 metres inland from II] all beaches. In those areas where only a sandspit occurs between a river channel and the sea, an extreme risk of total loss of land and property exists. All areas prone to coastal erosion should be excluded from 1 settlement programs.
I Flood Liable Lands
1 1.48 Land along the main river channels which is subject to flooding has been defined for the tidal and non-tidal stretches by the Public Works I Department and Water Resources Commission respectively. However, no authority has Statutory responsibility for the many lesser streams and creeks and the tributaries of the main river. Geomorphological or soil [II studies would enable identification of land at risk from flooding in these I lesser streams. 1.49 It is recommended that a thorough drainage catchment study be carried out El in any areas proposed for rural residential development and which could be considered to be at risk from flooding. I Land Subject to Landslip
I 1.50 In many of the hilly portions of the study area varying degrees of landslip risk exist. The risk is greatest where land slopes are in excess I of 100 (20% or 1 in 5) and the thickness of soil overlying rock is greater than about 1.5 metres. In other areas, especially after recent clearing I of thick forest vegetation and/or extensive cut and fill for roadworks or I yy- L
1 R Travers Morgan Pty Ltd 1.55 It is recommended that any rural residential proposals in alluvial areas I be subject to a detailed groundwater hydrological study to determine the presence/absence of the water table, its subsurface flow characteristics I and a professional judgement made as to its assimilative capacity for septic/sullage wastes.
I Dispersive Soils
1.56 The rocks present in the hilly portions of the study area essentially comprise a folded suite of metasedimentary rocks of the mudstone, shale, I stela type with lithic sandstones, volcanic rock types and limestones. These rocks commonly give rise to dispersive clay minerals during I weathering. Where soils are thin, skeletal or immature, this problem is greatest and all land management procedures must take this factor into account, particularly during clearing and earthworks. Apart from the fact I that revegetation of such disturbed land is made difficult and slow by the presence of dispersive clays in the soil, the greater problem is that of I soil erosion by rain and sheet-water flow and the resultant siltation of the downstream area.

1• VEGETATION (Holmes & Rooney)
I Introduction
1.01 The vegetation units of greatest concern in the natural environment of I coastal south-eastern Australia are rainforests (Goldstein 1977, National Parks and Wildlife Service 1979), wetlands (Goodrick 1 970, Fox 1973), I mangroves (Lear and Turner 1977) and heaths (Haigh 1981). In the Taree area the significance of these issues is greatly diminished because the environment has been fundamentally altered by activities associated with urban development, cultivation, grazing, forestry and mining. Natural I vegetation has been largely eliminated, numerous exotic animals and plants have been introduced, and the frequency and intensity of fires has been manipulated. Even so, certain rainforests possess either regional or I local significance, and the preservation of all wetlands, mangroves and heaths is important locally.
Natural Vegetation
1.02 Six principal types of natural vegetation may be distinguished in the I area:
i) Closed Forest (Rainforest) I This is a dense forest dominated by a hiqh diversity of mainly broad-leaved trees. On the more fertile soils or in sheltered I situations these trees may approach 40 metres in height. Near the sea and often on deep sands is a distinctive form, referred to as I littoral rainforest, in which the trees are considerably smaller and generally salt-tolerant. Typical elements of closed forest I include figs, palms, various laurels and myrtles, large vines, ferns and epiphytic orchids. Closed forest was originally well distributed on the flood plain I of the Manning River. Remnants include Wingham Brush and Coocumbac Island. Small areas of rainforest occur along l escarpments north of Lansdowne, and in sheltered situations in Kiwarrak and Yarratt State Forests. Littoral rainforest was I formerly almost continuous from Manning Point to Hallidays Point. These locations are two of the few significant remnants, others I being Farquhar Inlet, Saltwater and Red Head. I R Travers Morgan Pty Ltd
Open Forest (Scierophyll Forest) This forest is dominated by various combinations of myrtles, [1 mainly eucalypts. In most situations these trees exceed 25 metres in height. A typical species in this area is Blackbutt Eucalyptus pilularis, with an associated understorey that may vary from I luxuriant to relatively dry. Other dominant trees are Sydney Blue Gum E. saligna, Tallowwood E. microcorys, Flooded Gum E. grandis I and Brush Box Tristania conferta, with a generally luxuriant understorey; and Grey Gum E. propingua, Grey Ironbark E. I siderophloia, White Mahogany E. acmenoides (or E. umbra), Forest Red Gum E. tereticornis, Scribbly Gum F. ? haemostoma, Spotted Gum I E. maculata, Swamp Mahogany F. robusta and Turpentine Syncarpia glomulifera, with a generally dry understorey. The most extensive open forests are dedicated as State Forests. I Elsewhere they have been largely cleared, typically forming induced savannah woodlands. A notable exception is a moderately 1 extensive area of open forest contiguous with the south-eastern boundary of Yarratt State Forest and encompassing the Kate Kelly's I Crossing reserve. Presumably it would differ from the State Forest in not having been subjected to intensive silvicultural practices. I Scrub This community is dominated by small trees less than 10 metres in I height, typically banksias (e.g. Banksia integrifolia) and wattles (e.g. Acacia longifolia). It occupies mainly deep sands near the I sea. In protected sites it frequently grades into littoral rainforest. I Heath This community is a moderately dense low shrubland with a high I diversity of species. It occupies mainly deep sands near the sea. Some areas are sporadically inundated and are distinguished by the corresponding development of sedges. I Heath has a restricted distribution. It is confirmed essentially to Crowdy Bay National Park and its vicinity, and to lower [1 Khappinghat Creek (south of Saltwater). Mangroves I The community is a low closed forest or closed scrub subject to tidal inundation. It is composed of two species, Grey Mangrove I I R Travers Morgan Pty Ltd ' Avicennia marina and River Mangrove Aegiceras corniculatum. (Note: alternatively, mangroves may be classified as a type of wetland). Mangroves fringe many tidal watercourses. They are most extensive I and best developed on the lower Manning River, at Pelican Bay and south-west of Harrington. I vi) Wetlands These include shallow estuarine waters, (mangroves), saltflats, salt meadows, reed swamps, swamp forest (dominated by Casuarina 1 glauca and Melaleuca spp.), fresh meadows, seasonal fresh swamps, semi-permanent swamps and open fresh waters (see Goodrick 1970). I The original distribution of the various wetlands is difficult to determine; many have been drained, whereas a number of storages have been established for mainly agricultural or pastoral purposes. I The most extensive wetlands are the estuarine waters of the lower Manning River, including Farquhar Inlet. Wetlands on the floodplain between Coopernook and the lower IJawson River vary from R fresh to brackish and are mainly seasonal.
1.03 For the purpose of mapping the distribution of natural vegetation (see Map 3), the following units may be recognised:
- Closed forest (except littoral rainforest, combined with Open I Forest on map); - Open forest; - Scrub/Heath/Littoral rainforest; I - Mangroves; and - Swamp vegetation/Wetlands.
1.04 Most remaining closed forest areas are very small and impractical to map I separately; therefore these areas have not been distinguished from the open forest on the vegetation map. The description above will suffice for I information concerning their location.
1 05 Areas of savannah woodland or scattered trees could not be accurately 1 mapped at this scale and have been combined with cleared pasture on the
vegetation map. The vegetation map was produced from September 1981 I aerial photographs and is accurate at that date to a minimum area of approximately 100 ha.
I R Travers Morgan Pty Ltd I Plants of Special Interest
1.06 A number of plants are of special interest, with respect to geographic distribution or abundance. These include about 30 species of rainforest trees or shrubs that have known southern limits in the Camden Haven - Seal R Rocks region. Six of these are at their limits in the Taree area: Lepidozamia peroffskyana, Denhamia pittosporoides, Canthium odoratum, I Jagera pseudorhus, Guilfoylia monostylis and Aphananthe philippinensis (Williams 1979). There is also a eucalypt occurring locally in Kiwarrak State Forest, Rudder's Box E. rudderi, that is classified by Pryor (1981) as potentially vulnerable because of its relatively limited occurrence. A major habitat locality for this eucalypt is preserved from logging, as I noted in paragraph 3.02.
1.07 It is likely that a number of plant species occurring in the Taree area are considered to be threatened, rare, relict or of particular I biogeographic interest. However, there is apparently no specific information concerning them that has been properly documented. I REFERENCES

2. FAUNA (Holmes)
Introduction I
2.01 The fauna of coastal south-eastern Australia is diverse in all component groups. Nevertheless, it is only possible to critically examine local faunas in a regional context with reference to the better studied groups, typically the mammals and birds. The significance of the occurrence of particular species of reptiles, amphibians, fishes and invertebrates is usually more speculative. There is no published information that specifically documents any faunal group in the Taree area, though some records are maintained by the Forestry Comission (Taree) and the National Parks and Wildlife Service (Port Macquarie).
Maninals
2.02 A total of about 40 species of mammals has been recorded in or adjacent to the Taree area. This comprises two monotremes, 20 marsupials, 12 land placentals (including five exotic species) and at least seven bats.
2.03 The status of four vulnerable species is uncertain. The Platypus Ornithorynchus anatinus is probably confined to the upper reaches of larger watercourses. The Dusky Antechinus Antechinus swainsonhi is likely to occur in open forests where the ground layer is well developed. The Coastal Planigale Planigale maculata is a generally scarce species; one specimen was collected recently at Hannam Vale (per National Parks and Wildlife Service), so others may be expected near Taree. The Eastern Chestnut Mouse Pseudomys gracilicaudatus is another scarce species, recorded at Crowdy Bay (per Forestry Commission) and therefore likely to occur elsewhere in open forest near the coast.
2.04 The large colony of Grey-headed Fruit Bats Pteropus poliocephalus at Wingham Brush has been long established and is well known. From time to time it is considerably augmented in numbers by the mainly nomadic Little Red Fruit Bat P. scapulatus. Both species eat a number of blossoms and fruits, including cultivated varieties. I R Travers Morgan Ply Ltd I Birds
2.05 From what is documented concerning the distribution of birds in New South Wales (see Holmes and Morris 1981), it is reasonable to predict that about 200species occur regularly in the Taree area. At least 50 additional species would occur sporadically.
2.06 The lower Manning River is apparently only of subsidiary importance for aquatic birds. In contrast to estuaries such as those of the Hunter and Richmond Rivers, the number of migratory shorebirds is low, and there are no documented nesting colonies of herons, spoonbills or cormorants. When conditions are suitable, ducks nest prolifically at The Basin on the lower Dawson River (per B. Crisp), and seasonal fresh meadows west of Coopernook maybe expected to provide extensive foraging areas. Otherwise, aquatic birds depend mostly on the shallower parts of small permanent storages.
2.07 The Taree area corresponds broadly with the southern geographic limits of six coastal species. Although moderately common to abundant farther I north, all are scarce near Taree. The Brahminy Kite Haliastur indus forages along the lower Manning River and has nested at Mondrook. The Red-backed Button-quail Turnix maculosa and Red-backed Fairy-wren Malurus I melanocephalus occupy rank grasses and heath. The Forest Kingfisher Halcyon macleayii occurs in induced woodlands and on the margins of open I forest. The Barred Cuckoo-shrike Coracina lineata and Varied Triller Lalage leucomela inhabit mainly rainforests, but also visit fruiting trees I in more open habitats.
2.08 An additional six species are of special interest because they are generally rare, or greatly declining as a result of specialised nesting requirements. Most occupy vulnerable littoral habitats. A summary of I information concerning these species follows:
1) Black-necked Stork (Jabiru) Xenorhynchus asiaticus This is an essentially tropical species, rare in NSW. Each pair I has an extensive home range. Nesting has been recorded at Oxley Island (1975, per B. Crisp) and Hannam Vale (1981, per R. Cooper). I I R Travers Morgan Pty Ltd
Osprey Pandion haliaetus This cosmopolitan species is declining in southern Australia. It is rare in NSW, where less than 20 pairs nest in coastal locations I north of Port Stephens. Currently there are two nests known on the Manning River, at lower Miller's Creek (Mitchell Is.) and near I Cundletown (exact locations documented by National Parks and Wildlife Service). I - iii) Beach Stone-Curlew Esacus magnirostris This is an essentially tropical species, but during the last decade it has been recorded sporadically south to eastern Victoria. One nesting site is known in NSW. A record at Mitchell Island in 1975 (Rogers 1977) may indicate that it nests on the R lower Manning River (e.g. Farquhar Inlet). Pied Oystercatcher Haematopus longirostris I This species frequents beaches and tidal flats and is declining because of disturbance at nesting sites. It has been recorded I nesting along the beach from Manning Point to Farquhar Inlet (per B. Crisp). v) Little Tern Sterna albifrons I This cosmopolitan species nests in small colonies on open sandy areas near high water level, in the lower reaches of estuaries. I It is greatly declining in NSW because of disturbance at these sites. I It was recorded nesting at Farquhar Inlet until 1975 (per B. Crisp; also Morris 1979). Such a site would probably be used I again if the frequency of disturbance diminished. vi) Forest Raven Corvus tasmanicus I A form of this species is endemic to northern NSW. It was considered to be confined to the New England tableland until an isolated and declining coastal population was reported recently I (Debus 1980). It is restricted to an extremely narrow strip of coastal vegetation from Smoky Cape (Macleay River) to the Myall I Lakes. In the Taree area there are potential nesting sites in open forests such as at Khappinghat Creek, I and in littoral I I R Travers Morgan Pty Ltd
I INSECTS
2.09 Recent study of rainforests in the Taree area (by G Williams) has revealed the presence of two species of beetles that are of particular significance.Littoral rainforests from Harrington to Hallidays Point are the only known locations in Australia of a new species of dung beetle (genus Maoraxia). Related species occur in New Zealand, Fiji and Tonga. The rare King Christmas Beetle Anoplognathus viridianeus has been located in open forest and scrub on sandy soils, contiguous with littoral rainforest; and also in Yarratt State Forest. It is one of a few invertebrates in NSW that is being considered by the National Parks and Wildlife Service for measures of protection.

LOCALITIES OF ENVIRONMENTAL SIGNIFICANCE i Introduction 3.01 Several localities in the Taree area have significant value for the I preservation or conservation of particular habitats, or certain species of plants and animals. All should be protected. Although prospective rural development will in many instances be situated well distant from these I localities, it is important to anticipate how such developments may impinge upon them, either directly or indirectly. Ideally, at least the V lan& adjacent to these localities should have compatible development and programmes of management. Factors of greatest concern are fire, the I increasing direct impact of numerous visitors, and the reduction of - remaining areas of vegetation.
Description of Localities
3.02 The following localities (see Map4 ) are considered to be significant:
Crowdy Bay National Park This locality preserves a good example of heath. The I south-western boundary is vulnerable to frequent fire. Because heath occurs on soils of low fertility, it is susceptible to I nutrient enrichment and subsequent colonisation by weeds. Coocumbac Island Nature Reserve I This island in the Manning River at Taree preserves a small remnant of riverine rainforest. It is threatened mainly by weeds transported by floods. I State Forests The State Forests conserve extensive open forests (mainly dry I sclerophyll but also wet sclerophyll along drainage lines and sheltered areas), some minor rainforests, and their associated I fauna. There are no Flora Reserves within these State Forests, but in Kiwarrak State Forest, on the southern boundary north of Nabiac, is a Forest Preserve for Eucalyptus rudderi, (see Map 4 ). Fire is the only significant threat. iv) Manning Point; Farquhar Inlet (north); Saltwater; Red Head - I Hallidays Point. I I R Travers Morgan Pty Ltd
These are the locations of the principal remnants of littoral I rainforest. They are of great scientific interest, for example in the study of Pacific Ocean biogeography. They also provide I potential nesting sites for the Forest Raven. The greatest threat is the impact of visitors; correspondingly, while they are managed I for recreational rather than natural values, regeneration is impeded and they are vulnerable to invasion by weeds and fire. I v) Wingham Brush This locality preserves an example of riverine rainforest. It is the site of a long established colony of fruit bats. The rainforest has been severely degraded by a prolific invasion of weeds, which is the subject of a control programme administered by I the National Trust. Newby's Creek - Koolah Creek (Lansdowne) I These small catchments support moderately well developed rainforest, principally along an escarpment. This situation I ensures a measure of protection; also part of Newby's Creek adjoining Lansdowne State Forest has been proposed as a Wildlife Refuge (none exists elsewhere in the Taree area). Even so, more I intensive land use in adjacent areas is a potential threat. Lower Manning River; Farquhar Inlet I These estuarine environments include shallow waters, mangroves, saltflats, salt meadows and swamp forest. Sandy areas (mainly I beaches) provide nesting sites for vulnerable bird species, especially the Little Tern and Pied Oystercatcher, and possibly the Beach Stone-Curlew. The greatest threat is the impact of numerous visitors; this includes disturbance of nesting birds by uncontrolled vehicular access to beaches. I Lower Khappinghat Creek This locality has been proposed as a Nature Reserve by the I National Parks Association. It would preserve the only significant remnant of coastal vegetation that is continuous with I extensive open forest farther from the coast. It also provides potential nesting sites for the Forest Raven, Little Tern and Pied I Oystercatcher. The greatest threats are fire and the impact of visitors. I I I R Travers Morgan Pty Ltd
I ix) The Basin (lower Dawson River) The diverse and extensive wetland includes swamp forest, reed I swamps and seasonal fresh swamps. When conditions are suitable it is a valuable nesting area for aquatic birds. Because of the proximity to Taree it has a potential for educational purposes. I It could be severely degraded by intensive development in contiguous areas along the Lansdowne Road. I x) Old Bar Park This area supports a diverse coastal vegetation on both sand and clay soils. Significantly, it is contiguous with the estuarine environment of Farquhar Inlet. It is the subject of a current botanical survey. The greatest threats are fire and the impact of visitors. xi) Cundletown; (lower Miller's Creek) I These are nesting sites of the Osprey. Exact locations are documented (and monitored) by the National Parks and Wildlife I Service. I I

4. ARCHAEOLOGY (Holmes)
Introduction I
4.01 The principal aboriginal inhabitants of the Taree area were the Birpai (Birbai, Birripai). As happened elsewhere in Australia, the descendants of these people are scattered and much diminished in number. Many live at the Purfleet reserve. In anticipation of new State legislation, they are currently formulating a policy concerning aboriginal sites. They are seeking to convey their fundamental interest in ensuring that such places are protected from prospective or further development.
Aboriginal Sites
4.02 The National Parks and Wildlife Service maintains a register of all known aboriginal sites in New South Wales. This register documents the occurrence of nine sites within the Taree area (see Table Bi and Map 4 ). These include burial and ceremonial grounds, and mythological sites. There are no records of sites containing rock engravings or paintings.
4.03 At least four locations have contemporary significance for the aboriginal comunity. Near the Purfleet reserve there is a cemetery and a mythological site. At Saltwater, encompassing the recreation reserve administered by City Council, is a burial ground, a mythological site and a fish trap. This area is still visited regularly by many members of the Purfleet community. Finally, there are a further two burial grounds, one immediately north-west of Taree, the other near the Dingo Creek crossing on the Wherrol Creek Road.
4.04 The vicinity of Hallidays Point and Red Head (see Simon 1978, p. 31) is also a potential site of contemporary significance, but this requires proper documentation. It seems that at least two mythological sites are concerned.
4.05 Published reviews concerning the north coast region (see Ryan 1964, Bowdler 1982, Blomfield 1981) indicate that there has been no comprehensive archaeological survey of the Taree area. From what is known

about the former coastal aborigines, it seems reasonable to conclude that I many more sites remain to be detected. Potential sites include foreshores, margins of larger water courses, rock outcrops and hilltops. I Mythological sites are most likely to be associated with conspicuous natural features, such as unusual rock formations or rainforest I vegetation.
Protection Measures
4.06 To comply with the provisions of the National Parks and Wildlife Act, 1974, it may be necessary to employ a professional archaeologist before certain development works may proceed. Because the impact on a given aboriginal site will vary according to its location, state of preservation, size and significance, and the nature of the development, each instance requires independent assessment.
4.07 The National Parks and Wildlife Service has the statutory responsibility of protecting all aboriginal sites. Written consent must be obtained from the Director before a site, and any associated relics, may be wilfully disturbed, damaged or destroyed.
4.08 It is important that the aboriginal community be consulted during the initial stages of planning for development works. Normally this involves liaison with the National Parks and Wildlife Service. Conflict of interest may be obviated if concern expressed by the aboriginal community is adequately conveyed.
