Eucalyptus macarthurii (a tree) - vulnerable species listing
The Scientific Committee, established by the Threatened Species Conservation Act, has made a Final Determination to list the tree Eucalyptus macarthurii Deane & Maiden as a VULNERABLE SPECIES in Schedule 2 of the Act. Listing of vulnerable species is provided for by Part 2 of the Act.
This Determination has been superseded by the 2014 Determination (Endangered species listing).
NSW Scientific Committee - final determination
The Scientific Committee has found that:
1. Eucalyptus macarthurii H Deane & Maiden (family Myrtaceae) is described by Hill (2002) in Harden, G. (ed.) Flora of New South Wales. Vol. 2. 2nd Edition University of New South Wales Press, Sydney, p. 132 as: Tree to 40 m high; bark persistent on trunk and larger branches, grey-brown, shortly fibrous, thick, smooth above, grey, shedding in short ribbons. Juvenile leaves opposite, ovate to broad-lanceolate, cordate, dull green. Adult leaves disjunct, narrow-lanceolate, 8-16 cm long, 0.8-1.5 cm wide, green, dull, concolorous. Umbellasters 7-flowered; peduncle narrowly flattened or angular, 2-9 mm long; pedicels terete, 1-2 mm long. Buds ovoid or fusiform, 3-5 mm long, 2-3 mm diam., scar present; calyptra hemispherical or conical, shorter than or as long as and as wide as hypanthium. Fruit hemispherical, conical or campanulate, 3-5 mm long, 3-6 mm diam.; disc raised; valves exserted.
2. Eucalyptus macarthurii has a moderately restricted distribution. It is currently recorded from the Moss Vale District to Kanangra Boyd National Park. In the Southern Highlands it occurs mainly on private land, often as isolated individuals in, or on the edges, of paddocks. Isolated stands occur in the north west part of the range on the Boyd Plateau. The only known record in the conservation estate is within Kanangra Boyd National Park.
3. Although large mature trees exist, grazing and other forms of disturbance preclude establishment of seedlings in many locations, so that the current mature cohort of individuals is unlikely to be replaced unless protective measures are implemented. Other threats include loss of habitat through development, clearing and weed invasion inhibiting recruitment.
4. In view of the above the Scientific Committee is of the opinion that the tree Eucalyptus macarthurii Deane & Maiden is likely to become endangered in New South Wales unless the circumstances and factors threatening its survival or evolutionary development cease to operate.
