Scientific name: Brogo Wet Vine Forest in the South East Corner Bioregion
Gazetted date:
17 Nov 2000
Profile last updated:
05 Sep 2023
Description
Brogo Wet Vine Forest is a tall forest with a sparse small tree layer, open shrub layer and grassy ground layer. Forest Red Gum (Eucalyptus tereticornis) and Rough-barked Apple (Angophora floribunda) are the dominant tree species. The small tree layer is made up of one or more of Kurrajong (Brachychiton populneus), Sweet Pittosporum (Pittosporum undulatum), Hickory Wattle (Acacia implexa) and occasionally Port Jackson Fig (Ficus rubiginosa). The shrub layer is diverse and may include Cassinia trinerva, Tree Violet (Hymenanthera dentata), Coffee Bush (Breynia oblongifolia) and Blackthorn (Bursaria spinosa). The groundlayer is dominated by the grasses Weeping Grass (Microlaena stipoides), Creeping Beard Grass (Oplismenus imbecillis) and Forest Hedgehog Grass (Echinopogon ovatus), the herbs Kidney Weed (Dichondra repens), Stinking Pennywort (Hydrocotyle laxiflora), Large Tick-trefoil (Desmodium brachypodum), Stellaria flaccida and Glycine clandestina, and the ferns, Cheilanthes sieberi and Sickle Fern (Pellaea falcata). The grass species Hillside Burrgrass (Cenchrus caliculatus) is almost exclusively associated with this community in the Bega Valley region and is moderately common. This community is distinguished from other communities in the south east forests of NSW by the dominance of Forest Red Gum and the abundance of shrubs and vines.
Distribution
The Scientific Committee determination states that the Brogo Wet Vine Forest is confined to the Bega Valley area on the far south coast of NSW. It is found on the margins of the valley between Myrtle Mountain, Tantawangalo and Brogo, from Brogo to Cobargo and on a few hills within the valley, including the Meringola Peak area. However there is also some possibility of occurrence in Eurobodalla Shire, such as around Tilba Tilba, and possibly a few small instances further north.
Habitat and ecology
- Occurs mostly on steep, north-facing slopes on granites.
- Large outcrops of granite are common throughout occurrences of the community.
- A naturally restricted community, because it has specific requirements for its development.
- The majority of the remnants are found on private land.
- About half of the estimated original extent of this community has been cleared for agriculture.

Threats
- Continued clearing or degradation of remnants for agricultural activities and the development of small holdings.
- Continuous heavy grazing and trampling of remnants by grazing stock, resulting in loss of key plant species, reduced community structure, erosion and other soil changes (e.g. increased nutrient status).
- Fire regimes that lead to a change in structure or composition of the community may result in loss of extent, or the loss of key habitat components such as woody debris and hollow bearing trees can cause a decline in condition and function of the community.
- Invasion of remnants by non-native plant species, including noxious weeds, pasture species and environmental weeds.
- Dieback associated with a number of factors including the establishment of large Noisy Miner (Manorina melanocephala) and Bell Miner (M. melanophrys) colonies.
- Overgrazing and trampling by non-native vertebrate pest species (including deer, goats and rabbits).
- Lack of understanding of ecosystem processes can limit understanding of necessary management and the community response to management
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
- Erect on-site markers to alert maintenance staff to the presence of a high quality remnant or population of a threatened species.
- Encourage regeneration by fencing remnants, eliminating stock grazing and undertaking supplementary planting, if necessary.
- Undertake weed control within remnants, and in adjacent areas (taking care to spray or dig out only targeted weed species).
- Protect all sites from further clearing and disturbance.
- In remnants with large populations of Miners, undertake a program to enhance the habitat.
- Mark remnants onto maps (of the farm, shire, region, etc) and use to plan activities (e.g. remnant protection, rehabilitation, and infrastructure maintenance work).
