Scientific name: Semi-evergreen Vine Thicket in the Brigalow Belt South and Nandewar Bioregions
Gazetted date:
24 Dec 1999
Profile last updated:
23 Mar 2022
Description
A low, dense form of dry rainforest generally less than 10 m high, made up of vines and rainforest trees as well as some shrubs. This community often stands out as a bright green against surrounding woodland due to many species having bright-coloured leaves. The main canopy is dominated by rainforest species such as Red Olive Plum (Cassine australis var. angustifolia), Wilga (Geijera parvifolia) Native Olive (Notelaea microcarpa var. microcarpa) and Peach Bush (Ehretia membranifolia), with taller eucalypts and cypress pines from surrounding woodland vegetation emerging above the main canopy. Currant Bush (Carissa ovata) is often present and typical vines include Gargaloo (Parsonsia eucalytophylla) and Wonga Vine (Pandorea pandorana).
Distribution
A scattered distribution near Gunnedah, Barraba, Bingara and north of Warialda on the NSW North West Slopes and Plains, and also in Queensland.
Habitat and ecology
- This community often occurs on rocky hills, in deep, loam, high nutrient soils derived from basalt or other volcanic rocks, in areas which are sheltered from frequent fire.
- The community is comprised of vines, shrubs, and evergreen, semi-evergreen (or facultatively deciduous), and deciduous tree species which have affinities to coastal subtropical rainforest trees.

Threats
- Clearing of habitat for agriculture and grazing.
- Grazing and trampling by domestic stock.
- Clearing and damage to habitat by road maintenance works.
- Fragmentation and risk of extinction due to small, scattered remnants
- Lack of value and understanding of the TEC by landholders and managers of the TEC
- Overbrowsing by both domestic and wild goats
- Risk of fire both wildfire and hazard reduction burns
- Climate change leading to longer dry periods altering vegetation structure and composition
- Invasion and establishment of weed species changing community structure and floristic composition, particularly Green Panic Grass, Sabi Grass, Tiger Pear, and Tree Pear.
- Fox predation on Brush Turkeys
- Impact of pigs on Brush Turkeys and on germination of key plant species through consumption of fruit
- Increase in goannas, caused by dumping of carcasses, leading to higher mortality rates of brush turkeys.
