Invasive environmental weeds were identified as a potential long-term issue in the Dubbo Gully Plan of Management, Gosford City Council 1999. Strategic priority areas were identified by Councils Water & Sewerage Directorate staff and bush regeneration management plans were developed and implemented with support of local community, the Local Government Advisory Group, the Hawkesbury-Nepean Catchment Management Authority & the DIPNR. The plans involved selectively removing the most invasive weeds in the catchment by employing qualified bush regenerators, assisted by supervised TAFE students and local community volunteers to work along one kilometre of Mangrove Creek riparian zone and adjacent areas to favour native bush regeneration. Figures 3.21 – 3.22 Riparian zone lined with weeds before works. Privet control techniques being demonsrated and community training and reforestation planting day (G. Woolcock). An area of over 6.37 hectares of highly environmentally invasive weed trees were treated by bush regeneration contractors and Councils weeds team. These strategic works have reduced the spread of millions of invasive environmental & noxious weeds in the catchment over the last three years. Highly disturbed riparian areas were temporarily fenced by Wesley United Employment teams, environmentally invasive weeds treated by qualified bush regeneration teams and key areas planted out with endemic native trees such as Eucalyptus amplifolia and E. deanii to provide a stable vegetated creek edge and extend the riparian habitat corridor. Refer to before and after photos Figures 3.24 and 3.25. Investigations are underway for the feral animal control programs.

Woolcock). Community Education 1. Schools Waterwatch Program Biodiversity - Technical Report Page 73
Three public schools in the catchment area joined in the local streamwatch program. Students and teachers were provided with training in water quality testing and invertebrate sampling techniques. Mangrove Creek has one of the highest species diversity of the major rivers on the central coast and contains invertebrates only found in high quality waterways. The schools were provided with their own streamwatch kits by Council for analysing the health of their local streams. Schools can upload the water quality research onto the streamwatch website and compare results with other groups in NSW. 2. Community Flora and Fauna Surveys Mangrove and Mooney Creek (photos: G. Woolcock). Gosford Scouts and Rovers conducted flora and fauna surveys in the Mangrove Creek Catchment. The surveys identified common and threatened species from animal call playback and spotlighting. The Gosford Rovers were trained in vegetation sampling to assess the potential changes along the riparian zone from bushfires, people and cattle. A - 3.3.5 Kincumber Creek Riparian Rehabilitation Project Stage 1 of the Kincumber Creek Riparian Rehabilitation Project was initiated in response to an acknowledgement of the poor water quality in Kincumber Creek and the potential for rehabilitation of the riparian zone as a means to not only improve water quality, but also to create habitat for native animals, increase biodiversity and improve visual amenity. Kincumber Creek was identified as being one of the worst creeks in Gosford City based on water quality data and the degraded health of the riparian zone. Through the Environmental Levy funds were allocated towards a riparian rehabilitation project and Kincumber Creek was identified as a priority. Thus, the Kincumber Creek Riparian Rehabilitation project was initiated in 2001, and a partnership was formed with the then Central Coast Community Environment Network (CCCEN). The Kincumber community was consulted throughout the project, which was implemented through a Council/Central Coast Community Environment Network partnership and funded through Gosford City Council’s Environmental Levy. Stage 1 of the project included the development of the Kincumber Creek Riparian Management Plan, which outlined present conditions along the creek and made recommendations in the form of an action plan for 2003. A Kincumber Creek Riparian Management Plan (GCC and CCCEN 2003) was prepared which outlined the current state of the creek, and problems and assets within each section. Strategies to address priority sections and issues were outlined. These actions included professional bush regeneration, seed collection and plant propagation, community workshops, and development of educational material, initiating a Waterwatch group, installation of signs and fencing, community planting days and tree giveaways. The evaluation report for Stage 1 of the project (CCCEN 2004) found that most of the goals for the project were achieved. Biodiversity - Technical Report Page 74
