Scientific name: Brogo Vine Forest of the South East Corner Bioregion

Conservation status in NSW: Not listed

Commonwealth status: Endangered

Profile last updated: 13 Mar 2024

Description

This community typically reaches 15 to 25 metres tall with sparse to moderate canopy and subcanopy cover. Vines and twiners are commonly found in both the shrub and groundlayers. The ground layer is often highly diverse. Mature trees often form multiple hollows which provide habitat for fauna. Vegetation structure will vary across the extent of the ecological community, in relation to management and landscape features.

The canopy is typically dominated by Eucalyptus tereticornis (forest redgum) or sometimes Angophora floribunda (rough-barked apple) in various proportions with less frequent (but occasionally dominant)species Eucalyptus bosistoana (coast grey box), E. globoidea (white stringybark) and E. globulus subsp. maidenii . A discontinuous subcanopy maybe present with Ficus rubiginosa (PortJackson fig) being dominant. Other subcanopy and mid-stratum species include Acacia implexa (hickory wattle), Acacia mearnsii (black wattle), Brachychiton populneus (Kurrajong), Pittosporum undulatum (sweet pittosporum), Cassinia trinerva (three-veined cassinia), Breynia oblongifolia (coffee bush) and Melicytus dentatus (tree violet). Less frequently, Abutilon oxycarpum (flannel weed) and Deeringia amaranthoides (deeringia) are present. A range of vine species is highly characteristic, including Celastrus australis (staff climber), Geitonoplesium cymosum (scrambling lily), Clematis glycinoides (headache vine), Eustrephus latifolius (wombat berry), Marsdenia rostrata (milkvine) and Stephania japonica (snakevine). The ground stratum consists of various grasses such as Cenchrus caliculatus (hillside burrgrass), Microlaena stipoides (weeping grass),Echinopogon ovatus (forest hedgehog grass) and Oplismenus imbecillis (creeping beard grass), forbs such as Oxytes brachypoda (large tick-trefoil), Dichondra repens (kidney weed) and Sigesbeckia orientalis (Indian weed) and ferns such as Cheilanthes sieberi (poison rock fern) and Pellaea falcata (sickle fern).

Distribution

Brogo Vine Forest occurs in New South Wales within the South East Corner Bioregion, mainly in the Brogo area, but more broadly between the Moruya River in the north and Towamba in the south.

Habitat and ecology

Typically occurs on steep, often rocky slopes with a northerly aspect, less commonly on relatively flat terrain and infrequently in gullies.
Typically occurs on soils derived from granitoid substrates, rarely on other volcanic or sedimentary soils.
Mainly occurs at elevations of 200 m to 290 m above sea level (ASL), however may occur at up to 500 m ASL. The majority of the community occurs in areas with a mean annual rainfall of 900 mm to 1050 mm, although it can occur between 820 mm and 1290 mm.

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
Drying of the environment associated with climate change, exacerbating the effects of overgrazing and likely to contribute to die-back events.

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 0 priority actions to help recover the Brogo Vine Forest of the South East Corner Bioregion in New South Wales.
