Description
Kincumber Scribbly Gum Forest is an open forest with a tree canopy dominated by some combination of Eucalyptus racemosa (Scribbly Gum), Angophora costata (Smooth-barked Apple), Corymbia gummifera (Red Bloodwood), Syncarpia glomulifera (Turpentine) and Eucalyptus piperita (Sydney Peppermint). Allocasuarina littoralis (Black Sheoak) and Glochidion ferdinandi (Cheese Tree) may be present in the subcanopy. There is a prominent shrub layer which typically includes Dodonaea triquetra (Hopbush), Platylobium formosum, Persoonia levis (Broad-leaved Geebung), Polyscias sambucifolia (Elderberry Panax), Breynia oblongifolia (Coffee Bush), Leptospermum polygalifolium (Lemon-scented Tea-tree), Banksia spinulosa var. collina (Hill Banksia), Epacris pulchella, Grevillea linearifolia and Lomatia silaifolia (Crinkle Bush). The groundcover comprises herbs, scramblers, grasses, sedges and ferns, including Billardiera scandens (Appleberry), Cassytha glabella, Dianella caerulea (Blue Flax Lily), Entolasia stricta (Wiry Panic), Lepidosperma laterale, Pratia purpurascens (Whiteroot), Pteridium esculentum (Bracken), Smilax glyciphylla (Sweet Sarsaparilla) and Tetrarrhena juncea (Wire Grass).
Distribution
Kincumber Scribbly Gum Forest is restricted to a small area on the Bouddi Peninsula on the NSW Central Coast south of Kincumber. It occurs in the Gosford LGA. The total remaining area of Kincumber Scribbly Gum Forest to thought to be less than 100 ha. within an area of about 4 km2.
Habitat and ecology
- Occurs on gently undulating areas on sandy soils of the Erina soil landscape, derived from sandstones of the Triassic Narrabeen group.

Threats
- Clearing and fragmentation of Kincumber Scribbly Gum Forest due to the rapidly growing population and demand for land on the Central Coast of NSW.
- Intensifying urban and industrial land use in the area surrounding Kincumber Scribbly Gum Forest exposes the community to increased threat from degradation by weed invasion and from activities such as altered fire regimes, rubbish dumping and heavy recreational use.
- Disturbance from recreational users, including rubbish dumping, four wheel drive, motor bike, and mountain bike riding.
- Mixed weeds - Garden escapees, lilly, and new and emerging weeds.
- Inappropriate fire regimes.
Recovery strategies
A Saving Our Species conservation project is currently being developed for this species and will be available soon. For information on how you can contribute to this species' recovery, see the Activities to assist this species section below.
Activities to assist this species
- Promote public involvement in bush rehabilitation activities.
- Apply appropriate fire regimes to areas of Kincumber Scribbly Gum Forest. A fire interval of not less than 7 years is probably required to maintain a shrubby understorey.
- Prevent further clearing and fragmentation of this community.
