Scientific name: Corynocarpus rupestris subsp. rupestris

Description
Glenugie Karaka is a small tree or large shrub 2 – 5 m tall. Its trunk is usually multi-stemmed and has smooth, semi-corky bark with broad, shallow fissures. It is densely bushy with large, stiff glossy leaves, 5 – 18 cm long. Leaves on young plants or on the lower parts of adult plants are so strongly and sharply toothed that they appear to be of a different species. Some intermediate leaves are usually present. The small white flowers are held in clusters 10 – 21 cm in length. Fruits are red, round and 1 cm in diameter, with a tiny point on the end.
Distribution
This tree is known from Glenugie Peak Flora Reserve, south-east of Grafton, north to Wardell.
Habitat and ecology
- Dry rainforest on steep basalt boulder slopes. Soil is scarce but relatively high in nutrients and very well-drained.
- Fire is generally excluded by the rocky terrain and absence of ground litter.

Threats
- Fire.
- Risk of extinction because population is small and habitat is restricted.
- Damage to plants and habitat by visitors.
- Invasion of habitat by weeds, particularly Lantana.
- Risk of extinction because habitat and distribution restricted.
Recovery strategies
Priority actions are the specific, practical things that must be done to recover a threatened species, population or ecological
community. The Office of Environment and Heritage has identified
20 priority actions
to help recover the Glenugie Karaka in New South Wales.
Activities to assist this species
- Protect known habitat from fire.
- Protect areas of habitat from damage or disturbance.
- Protect rainforest from disturbance by visitors to Glenugie Peak.
- Control weeds in known habitat.
- Report new occurrences of Glenugie Karaka to OEH.
- Assess ecological requirements, seed germination and propagation requirements.
- Monitor known populations threats and population dynamics.
- Establish live ex-situ population and maintain viable ex-situ seed storage.
- Investigate options for linking, enhancing or establishing additional populations.
