Scientific name: Kurnell Dune Forest in the Sutherland Shire and City of Rockdale
Gazetted date:
29 Jan 1999
Profile last updated:
13 Nov 2024
Description
A low open sclerophyll forest community with a distinctive moist forest component in its flora. The community occupies coastal dune sand and is often found in association with areas of sclerophyll heath and scrub. Characteristic sclerophyll tree and shrub species include Angophora costata, Banksia ericifolia, Banksia serrata, Eucalyptus botryoides, Eucalyptus robusta, Leptospermum laevigatum and Monotoca elliptica. The moist component of the flora is characterised by species including Breynia oblongifolia, Cissus antarctica, Cissus hypoglauca, Clerodendrum tomentosum, Cupaniopsis anacardioides, Elaeocarpus reticulatus, Endiandra sieberi, Glochidion ferdinandi, Maclura cochinchinensis, Notelaea longifolia, Rapanea variabilis and Stephania japonica var. discolor.
Distribution
Occurs within the local government areas (LGAs) of Sutherland and Rockdale. Within Sutherland LGA, major occurrences of the community are found on the Kurnell Peninsula, with other stands near Bundeena. Within Rockdale LGA, the community is recorded from Leo Smith Reserve.
Habitat and ecology
- Occurs on coastal dune sand.
- Can be differentiated from the Eastern Suburbs Banksia Scrub (ESBS) endangered ecological community by the following features: Kurnell Dune Forest (KDF) contains a considerable mesomorphic element in the flora, which is absent or less dominant in ESBS; KDF has a forest structure rather than the predominantly scrub structure of ESBS; and KDF occurs on younger sands than those of ESBS.

Threats
- Habitat degradation by woody weed invasion especially bitou bush, lantana and asparagus fern.
- Disturbance of vegetation by visitors and recreational users to sites in some cases accessing it illegally.
- Inappropriate fire regime varying from too frequent fire to lack of fire
- Risk of extinction from isolated fragments on non-secure tenures
- Clearing for infrastructure, potentially F6 motorway
- Feral deer causing disturbance including tracking and browsing leading to erosion.
- Inundation from sea level rise and increased extreme storm events
- Lack of knowledge about the distribution, classification and mapping of the community.
- Disturbances associated with the installation and maintenance of utilities.
- Inappropriate plantings in and around remnants.
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
- Support and provide information to land managers and maintenance crews regarding appropriate management.
- Determine and apply appropriate fire management practices.
- Implement measures to control inappropriate water flows.
- Install gates, fencing, formal tracks and signs to manage access and prevent rubbish dumping.
- Protect remnants from clearing and further fragmentation.
- Restore degraded habitat using bush regeneration techniques.
- Prepare and implement site specific plans of management.
