Description

Reference: QLD005
Bioregion: Brigalow Belt North
Criteria for inclusion in Directory: 1,2,3,4,5,6
Catchment: Haughton

Location

19 degrees 27' 43" S, 147 degrees 08' 52" E; the site extends c.70 kilometres from the mouth of the Ross River in the east to Lynch's Beach (Alva) in the west, and from 3 to 18 kilometres north to south, with its centre 30 kilometres north-west of Ayr.

Significance

One of very few records of the bare rumped sheathtail bat (Saccolaimus saccolaimus nudicluniatus) (Nce, Sr) comes from Jerona in the central part of the aggregation. It is restricted to coastal woodland and is dependant on hollows in old poplar gum (Eucalyptus platyphylla) trees for roosting and breeding. The Irrawaddy dolphin (Orcaella brevirostris) (Sr) is likely to be present in the aggregation's estuaries. The marine areas have substantial populations of the threatened dugong (Dugong dugon) (Sv), green turtle (Chelonia mydas) (Nv, Sv) and loggerhead turtle (Caretta caretta) (Ne, Se). The estuarine crocodile (Crocodylus porosus) (Sv) also occurs within the area. The rusty monitor (Varanus semiremex) (Sr) has been recorded in mangroves on the western side of the aggregation.

The avifauna is a diverse and important component of the fauna of the area, and perhaps the best known. The aggregation is important for nearly 50 percent of the species listed in the Migratory Species section of the federal Environment Protection & Biodiversity Conservation Act. The Cape Bowling Green spit is a migratory stop over roost-feeding point for 20 000-40 000 small waders, and the arrival and departure point for 2000-3000 white-winged black terns (Chlidonias leucoptera). It is probable that these numbers constitute more than one percent of the population of this species. Of the 285 native species recorded from the aggregation, at least 103 are known to breed there. A total of 12 species recorded here are considered rare or threatened. This includes the little tern (Sterna albifrons) (Se), beach stone-curlew (Esacus neglectus) (Sv) and crimson finch (eastern form) (Neochmia phaeton iredalei) (Sv). Other rare species (all listed Sr) are: grey goshawk (Accipiter novaehollandiae), square-tailed kite (Lophoictinia isura), cotton pygmy-goose (Nettapus coromandelianus), white-rumped swiftlet (Collocalia spodiopygius), black-necked stork (Ephippiorhynchus asiaticus), sooty oystercatcher (Haematopus fuliginosus), black-chinned honeyeater (Melithreptus gularis), Lewin's rail (Rallus pectoralis), and eastern curlew (Numenius madagascariensis). Substantial breeding populations of the brolga (Grus rubicundus) and magpie goose (Anseranas semipalmata) occur in the sedge swamps of the area in late summer. It is probable that the aggregation supports one percent or more of the national brolga population during the post breeding season when the highest numbers are present.
