Scientific name: Eucalyptus langleyi
Common name: Albatross Mallee
Other names: Green Mallee Ash, Nowra Mallee, Nowra Mallee Ash
Conventionally accepted as Eucalyptus langleyi (CHAH 2010).
The Albatross Mallee is a eucalypt species growing 5–6 m in height with multiple stems (mallee). The bark is smooth, and variable in colour from brown to grey, green or pink, and shed in long ribbons (Harden 1991; Hill & Johnson 1991; Plantnet 2012).
Juvenile leaves are broadly oval-shaped and glossy green in colour. Adult leaves are large, lance-shaped, approximately 18 cm long by 4 cm wide, also glossy-green, and alternate along stems. Adult leaves have obscure veins but prominently thickened margins (Plantnet 2012).
Flower buds are club-shaped, have a hemispherical cap and look minutely warty. Cream flowers in clusters of 7 are borne on a flattened stalk (peduncle) 8–12 mm long and up to 7 mm wide. Each individual flower stalk (pedicel) is 0–2 mm long and angular (flattened). The fruits are hemispherical or urn-shaped, with 3 or 4 chambers, ribbed with enclosed valves, 8–10 mm long and in diameter, sometimes with 1–3 vertical ridges and tips often exserted (protruding). Seeds are dull, grey-brown, kidney shaped but angular, to 2.5 mm long (Plantnet 2012).
The Albatross Mallee occurs inland west and south-west of Nowra on the south coast of NSW (Brooker & Kleinig 1999; Hill & Johnson 1991). The main occurrence of the Albatross Mallee is to the south-west of Nowra as far as Yarramunmun Creek and on rocky outcrops near the Tomerong-Yerriyong area with a small, isolated stand found north of the Shoalhaven River near Nowra (NSW DECCW 2005du; NSW OEH 2012c).
There is no published data to estimate the species to estimate the species' area of occurrence, however, an unsourced publication suggests that the species occurs in an area of approximately 12 x 4 km (NRMS 2011).
There is no published data on the total population, however, an unsourced publication suggests that the Albatross Mallee has an estimated total population of 2300 plants over approximately 25 sites, several of which contain several hundred plants each (NRMS 2011).
The Endangered Population in the Shoalhaven Local Government Area listed under the TSC Act consisted of 20 plants in a 2008 (down from 32 in 1998) and occurred as a series of fragmented stands across approximately 1.3 km² on land owned by Shoalhaven City Council and in Bomaderry Creek Regional Park (NSW SC 2010). The Endangered Population is approximately 5 km from the nearest population of the Albatross Mallee to the south-west, across the Shoalhaven River (NSW SC 2010).
Populations of the Albatross Mallee are known to occur in the Parma Creek Nature Reserve (at the eastern end of the Nowra-Braidwood Road (Main Road No. 92)) (NRMS 2011), land owned by Shoalhaven City Council (NSW SC 2010) and in Bomaderry Creek Regional Park (NSW SC 2010).
The main occurrences of the Albatross Mallee are on shallow, poorly drained sandy soils over sandstone or associated with laterite (Brooker & Kleinig 1999; Hill & Johnson 1991). It occurs on plateaux in highly dissected areas, often in heath patches surrounded by woodland of Red Bloodwood (Corymbia gummifera), Yertchuk (Eucalyptus consideniana) and a 'Scribbly Gum', probably E. racemosa (Brooker 2001 pers. comm; Hill & Johnson 1991).
The isolated northern population occurs on skeletal soils on rocky sloping Nowra Sandstone outcrops along Bomaderry Creek, in woodland dominated by Grey Gum (E. punctata), but sometimes with Spotted Gum (C. maculata) present. The woodland habitat has a shrubby midstorey comprising species such as Sweet Pittosporum (Pittosporum undulatum), Tick Bush (Kunzea ambigua), Bracelet Honey-myrtle (Melaleuca armillaris), Black Sheaok (Allocasuarina littoralis), Tea-tree (Leptospermum spp.) and Sandpaper Fig (Ficus coronata) (NSW OEH 2012c; NSW SC 2010).
The northern population occurs at an altitude of 30–40 m above sea level (asl) whilst the southern populations occur at between 130–255 m asl (NSW OEH 2012c).
The Albatross Mallee is recorded to flower between May and June (Brooker & Kleinig 1999), with insects the suggested pollinators (Briggs 2009 pers. comm. cited in NSW OEH 2012c). Pollination of plants is limited spatially (NSW SC 2010), with an estimate of pollen movements for eucalypts of less than 1 km, with rare events of greater than 5 km (Potts et al. 2003, cited in NSW OEH 2012c). Seed dispersal is also over limited distances, with estimates of less than twice a tree's height, though distances of up to 310 m may occur in favourable conditions. Therefore isolated populations of this species may have gene combinations that are not present in other populations (NSW SC 2010). Vigorous regrowth has been observed from plants that have been burnt only occasionally, however regrowth becomes weak on frequently burnt plants and no seedling regrowth has been observed within the isolated northern population (NSW OEH 2012c).
The Albatross Mallee may be mistaken for the Yellow-top Mallee Ash (E. luehmanniana), which has its southern most extent in Bulli approximately 90 km north of Nowra. The Yellow-top Mallee Ash has duller, grey juvenile leaves and coarser buds and fruit (Brooker & Kleinig 1996). It can also be mistaken for the Faulconbridge Mallee Ash (E. burgessiana) found in the Blue Mountains area, which does not have flattened stems and has narrower adult leaves (2.5 cm wide), smaller buds (7–10 mm long and 3–4 mm wide) and lacks the distinctly winged shoots of the Albatross Mallee (Brooker & Kleinig 1999; NSW DECCW 2005du; Plantnet 2012).
The main identified threats to Albatross Mallee are (Hill & Johnson 1991; NSW OEH 2012c):
- residential and recreational development and related infrastructure such as road, power, trail and pipeline construction/maintenance
- illegal rubbish dumping
- weed invasion suppressing seedling establishment
- trampling of seedlings and damage to new growth from stems and lignotubers by recreational users of the area in which the population occurs.
The main potential threats to Albatross Mallee include (Hill & Johnson 1991; NSW OEH 2012c):
- habitat loss through clearing, with some individuals likely to be lost if the central route of the proposed Bomaderry Link Road is approved
- inappropriate fire regimes with frequent fire events combined with drought conditions responsible for the death of several individuals over the past 20 years
- stochastic events such as fire and drought due to the small population size and restricted distribution.
Management documents relevant to the Albatross Mallee are at the start of the profile.
