Eucalyptus scoparia (a tree) - endangered species listing

NSW Scientific Committee - final determination



The Scientific Committee, established by the Threatened Species Conservation Act, has made a Final Determination to list the treeEucalyptus scoparia Maiden as an ENDANGERED speciesin Part 1 of Schedule 1 of the Act. Listing of endangered species is provided for by Part 2 of the Act.

The Scientific Committee has found that:

1.Eucalyptus scoparia(family Myrtaceae) is described by G.M. Chippendale,Flora of AustraliaVolume 19 (1988) as:

Tree to 15 m. Bark smooth, powdery throughout, white to pale grey. Juvenile leaves opposite to subopposite, petiolate, narrowly elliptic, green, slightly discolorous. Adult leaves alternate, narrowly lanceolate to linear-lanceolate, acuminate; lamina 10-15 cm long, 0.6-1 cm wide, shining, green; lateral veins faint, at 12-15 degrees; intramarginal vein up to 1 mm from margin; petiole terete, 8-12 mm long. Peduncle slightly flattened or terete, 4-8 mm long; pedicels terete, 2-4 mm long. Buds ovoid; operculun conical, slightly rostrate, c. 3 mm long, 3-4 mm wide; hypanthium cylindrical, 2-3 mm long, 3-4 mm wide. Fruits ovoid, 4-5 mm long and wide; disc ascending; valves usually 3, level or slightly exserted.

2. The species occurs in Queensland and reaches its southern limit in New South Wales, where it has only recently been discovered. In New South Wales, it is found on well drained granitic hilltops, slopes and outcrops, often as scattered trees in open forest and woodland.

3. There are only three known locations within NSW, all near Tenterfield in the far northern New England Tableland Bioregion. Population sizes are small and none occur within conservation reserves.

4. Clearing of native vegetation may be a threat in some locations. The species is further threatened due to small population size and stochastic events.

5. In view of the above the Scientific Committee is of the opinion that Eucalyptus scopariais likely to become extinct in nature in New South Wales unless the circumstances and factors threatening its survival or evolutionary development cease to operate.
