Black Jungle Reserve, Black Jungle Palm Site and the Black Jungle Orchid Site are included on the Register of the National Estate, for their natural values (Australian Heritage Council). Four conservation dependent species, including two which are listed in the IUCN Red List, are also found within the reserve and are listed below:
Luisia trsitis, Hook.f., orchid This species is listed as Vulnerable by IUCN as less than 1000 mature individuals occupy an area of less than 20 km2 (Holmes et al. 2005). This epiphytic orchid species grows in straggly clumps and has wiry, erect or semi-pendulous slender stems up to 30 cm long. The roots are thick and cord-like, approx. 5 mm wide. The inflorescence raceme is up to 15 cm long with groups of 1 to 3 flowers of green or yellow-green, and a dark red to burgundy centre, approximately 1 cm wide. Flowering occurs from November to December, but has also been recorded in February (Holmes et al. 2005).
L. tristis is found on the margins of monsoon vine forest and rainforest in areas of relatively bright light (suggesting reliance on breaks in the canopy) and is associated with other epiphytes (Holmes et al. 2005). This orchid has been recorded in Bankers Jungle and Black Creek, within the Black Jungle Conservation Reserve, Koolpinyah Station and Melville Island (Russell-Smith 1991). These are the only known mainland records of this species (Holmes et al. 2005; Russell-Smith 1991). Both Bankers Jungle and Black Creek are spring-fed monsoon rainforest patches on the margin of the Adelaide River Floodplain (Holmes et al. 2005; Russell-Smith 1991).
Ptychosperma bleeseri Burret, Darwin palm Not yet assessed by the IUCN. The species is listed as endangered under the Environment Protection and Biodiversity Conservation Act 1999 and specially protected under sections 45 and 47 of the Territory Parks and Wildlife Conservation Act 1993 (Hay 1997; Parks & Wildlife Commission). The palm is found in only eight small rainforest patches southeast of Darwin, within the Adelaide and
Howard River catchments (Barrow et al. 1993; Dept. NT Parks & Wildlife Comm.; Liddle et al. 2006). Palm habitats occur in an area 30 km long by 20 km wide forming a total area of 40 ha (Dept. NT Parks & Wildlife Commission; Liddle et al. 2006). Three of the eight patches occur within the Black Jungle Conservation Reserve: (Barrow et al. 1993; Parks & Wildlife Commission) Black Creek, portions of rainforest at Crocodile Creek and BJ3 and are listed in the Register of the National Estate under the Australian Heritage Commission Act 1975 (Parks & Wildlife Commission). The remaining patches occur on freehold or pastoral lease land (Dept Env & Heritage 2003; Liddle et al. 2006; Parks & Wildlife Commission). P. bleeseri, commonly known as the Darwin Palm, has a slender growth habit with a height of up to 12 m (Liddle et al. 2006). The multiple green trunks are 3 – 6 cm wide and the feathery fronds have leaflets that grow up to 1.5 m long (Liddle et al. 2006). Flowering spikes are produced in the dry season, April to August, with the main fruiting period occurring between August and December (Dept. Env. & Heritage 2003; Liddle et al. 2006). Threats to the species include invasion by weeds, habitat degradation caused by feral animals including grazing of seedling by pigs and changes in water quantity and quality due to changing land use in the catchment (Barrow et al. 1993; Liddle et al. 2006). Intense fires can also threaten regeneration by eliminating adult plants and preventing seedling establishment (Barrow et al. 1993; Dept. Env. & Heritage; Liddle et al. 2006).
Typhonium johnsonianum A. Hay and S.M. Taylor Family: Aracea Order: Arales Red List Category and criteria: Vulnerable D1 and 2 T. johnsonianum is known only by 2 specimens collected in 1993 and 1994, both within the Black Jungle Reserve in the Northern Territory, Australia (Hay 1997; Hay et al. 1996). The extent of occurrence and area of occupancy for the species have been estimated as less than 100 and 10 km2 respectively (Hay 1997; Hay et al. 1996). This species is known exclusively from the reserve, surrounding threats such as expanding agriculture,
overgrazing and mining are not likely to affect this species (Hay 1997). Although T. johnsonianum was found in wet monsoon forest with a high water table during the wet season, conditions are much different in the dry season and fires, therefore, could be a serious threat, considering the restricted area and number of individuals currently known (Hay 1997; Hay et al. 1996). T. johnsonianum is therefore listed as Vulnerable under D1 and D2 (IUCN Red List; Hay 1997; Hay et al. 1996). The species is found in open grassy clearings between Acacia auriculiformis and Melaleuca forest with Lophostemon lactifluus near the flood plain edge, in sandy well drained soil with seasonal inundation (Hay 1997; Hay et al. 1996).
Nososticta koolpinyah, (Order: Odonata) Koolpinyah threadtail dragonfly Watson and Theischinger 1984. Data Deficient ver 3.1 The species is endemic to Australia and the range includes Black Jungle, Koolpinyah Station and Melville Island in the Northern Territory and is considered as a rare to scarce species which frequents freshwater streams and terrestrial habitats (Endersby 2012; Hawking 2009). Threats to this dragonfly include farming, agro-industry and mining which is believed to negatively impact on the habitat of this species (Hawking 2009). ==See also==
