Scientific name: Umina Coastal Sandplain Woodland in the Sydney Basin Bioregion
Gazetted date:
06 Dec 2002
Profile last updated:
07 Sep 2017
Description
A low woodland dominated by trees of Eucalyptus botryoides and Angophora floribunda with a diverse understorey of sclerophyllous shrubs species including Banksia integrifolia, Banksia serrata, Monotoca elliptica, Macrozamia communis, Acacia ulicifolia, Platysace lanceolata, Acacia suaveolens and Allocasuarina littoralis. Eucalyptus botryoides is the dominant tree in the zone immediately behind the beach, while Angophora floribunda is dominant in the zone beyond up to 2 km from the beach. The community contains many more species and other references should be consulted to identify these.
Distribution
Largely restricted to coastal sands on the Umina, Woy Woy and Ettalong Sandplain, a beach ridge system within the Gosford local government area. Including ecotonal areas, less than 10% (being less than 10 hectares) of the community's estimated original cover of about 80 hectares remains. This comprises four main remnants at Umina, while a few smaller remnant patches and scattered trees around Pearl Beach and Patonga and elsewhere on the 'Peninsula' indicate its former distribution.
Habitat and ecology
- Occurs on sandy soils (iron podzols) of the Woy Woy Soil Landscape which are distinguished from the humus podsols generally associated with foothill talus slopes further away from the coast on which Angophora costata predominates.

Threats
- Habitat loss through developmental pressures.
- Inappropriate fire regime due to unplanned fires/arson.
- Encroachment into the TEC from neighbouring properties including slashing and mowing.
- Rubbish dumping including rubbish left by recreational users and squatters.
- Invasion of remnants by non-native plant species, including environmental weeds.
- Increase disturbance and fragmentation of TEC from motorbikes and the creation of trails.
- Lack of knowledge of location and condition of TEC.
- Grazing and disturbance caused by rabbits.
- Vulnerable to coastal processes.
- Encroachment into the TEC from rail corridor, roads and utilities.
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
- Manage fire frequency consistent with the ecological requirements of the community, particularly in the main remnants.
- Manage rubbish dumping.
- Encourage individual remnant tree retention and recruitment in drainage reserves and other small remnant areas by reducing slashing and mowing.
- Fence suitable areas strategically to discourage inappropriate informal track creation.
- Manage weed infestation.
- Encourage bush regeneration activities in the remaining remnants.
