This is a threatened ecological community.

Critical actions for this ecological community

The key threats to the viability of landscape-managed ecological communities are loss, fragmentation and degradation of habitat, and widespread pervasive factors such as impacts of climate change. Many of these threats are addressed by NSW planning, native vegetation, and biodiversity legislation, policy and programs including the offsets program (BioBanking, NSW Biodiversity Offsets Policy for Major Projects), Biodiversity Certification, management of environmental water and reservation under the National Parks and Wildlife Act 1974.

Threats to this ecological community are outlined here.

The actions listed in the action toolbox are supplementary to NSW legislation, policy and programs and can be used by stakeholders, where applicable to guide management at a site, regional or state scale.

Action DescriptionScale
Consult with landholders about participating in conservation agreements (preferably long-term in perpetuity) to protect the TEC on their property. Liaise with local aboriginal groups about TEC stewardship. Area, Site
Identify the 'best available' remaining remnants of the TEC in private lands and council reserves. These remnants should be targeted for potential conservation agreements and for creating corridors to reconnect island remnants through revegetation and the creation of buffer zones around established reserves. Site, Area
Liaise with Council to develop a new residents kit containing information about weed control, minimising disturbance (clearing, grazing and rubbish dumping) in the TEC, and provide an educational pamphlet drop for Landcare days. Site, Area
Identify and map green corridors with the aim of restoring TEC connectivity. Use the NSW government (2015) Biodiversity Investment Opportunities Map - Mapping Priority Investment Areas for the Cumberland Sub region, for the Cumberland plains areas. Replant corridors and buffer areas with native, appropriate TEC species. Seeds and tube stock for replanting should be collected from Council nurseries, herbarium or other regulated nurseries with known genetics to prevent disease introduction and inbreeding potential. Site, Area
Develop and run urban ecology programs e.g. native planting days, distribute free plants to local residents (TEC specific species to identified areas with TEC present), coordinate supervised landcare days in Reserves with the TEC. Site, Area
Consult with landholders about strategic grazing in TEC remnants i.e. do not allow goats in TEC areas, regularly rotate other livestock out of TEC remnants to prevent over browsing and loss of understorey species. Alternatively remove livestock altogether from TEC remnants and fence areas off (non-barbed wire). Please note that if livestock is removed mechanical/fire disturbance may be required to maintain/improve the condition of the TEC. Site, Area
Liaise with the Rural Fire Service and other land managers about minimising clearing in the TEC by using existing tracks/fire trials as fire breaks or preventing clearing for additional fire breaks. Site, Area
Control invasive grasses before seed sets by burning, waiting for new shoots to appear, and hand spraying new shoots (targeted only) with grass specific chemical treatment in localised patches and repeating when necessary. This may need to be repeated several times in the first year to remove the bulk of invasive grasses. Only use suitable herbicides that are safe in aquatic environments for treatment in close vicinity to waterways. Consider all non-herbicides methodology or a combination of chemical and non-chemical methods as a preferable technique. Site, Area
Undertake local, manual control of Bridal Creeper, Tiger Pear, and Mother of Millions then stock pile removed weeds under black plastic (solarisation). Site, Area
Develop long-term plan for ongoing burns of sections at 7–15 year intervals for entire mapped TEC. Continue to evaluate fire-frequency recommendations for this TEC as fire ecology for TECs evolve and ensure any adjustments are reflected in all relevant databases Site, Area
Consult with the Aboriginal community to investigate options for cultural burning in TEC remnants. Site, Area
Install post-fire fencing (temporary) at strategic locations after burning TEC remnants in reserves to control access and associated impacts of disturbance to exposed soils. Site, Area
Provide residents and local schools with information on the impacts of arson-lit fires on the TEC. Identify key access roads and install surveillance cameras to reduce the likelihood of arson occurring. Site, Area
Identify informal tracks in TEC remnants and close them using natural barriers such as logs and plantings (indigenous to the TEC). Work with land managers to prevent damage and disturbance by visitors by managing access to larger tracks/fire trails (including vehicular and pedestrian) through the installation of bollards, gates, and/or fencing at strategic locations and/or the use of deterrent signage. Revegetate or encourage natural regeneration following any track closure. Site, Area
Install signs at strategic locations both interpretive/educational and compliance/warning to help with the prevention of illegal entry to the bushland with vehicles and mountain bikes, as well as to prevent illegal dumping. Site, Area
Increase community awareness and education within reserves through discovery walks, holding landcare days, distributing information through the community and visitor centres. Conduct workshops in University farm facilities at Richmond demonstrating the importance of the TEC, good farming practice within the TEC, and appropriate recreational use within the TEC. Site, Area
Apply strict hygiene protocols in reserves for bush regenerators, managers, utility workers, and vehicles in areas down stream of Kemps Creek. The Saving our Species Plant Hygiene Protocol should be used as a guide to develop hygiene procedures. Site, Area
Monitor riparian and trackside areas of the TEC downstream of Kemps Creek Nature Reserve for signs of the 'new' phytophera(s) infection (two new pathogens identified). If the signs of the pathogen are suspected, soil testing must be undertaken and a plan of management to control the pathogens must be developed and employed as soon as possible. The Plan of Management may need to address the safe and responsible disposal of soils, sedimentation and waste water from the local market gardens. Site, Area
Research the two 'new' Phytophthora pathogens present in Kemps Creek Nature Reserve to determine the level of threat to the TEC within the reserve and downstream of the reserve. Site, Area
Implement control programs for deer populations in western Sydney. Culling programs are preferable but if new control techniques are identified these may be applied. Site, Area, State

How will this ecological community be managed?

Key management sites for this ecological community are being identified by the Office of Environment and Heritage and other program partners, where feasible, cost-effective and beneficial to the ecological community. Currently, 1 management site has been identified for this ecological community.
