• Development and implementation of a Fox Control Program for council reserves 2004 - ongoing • Indoor Cat Education Program commenced in 2004 • Environmental weeds list developed and included in Vegetation DCP • Greenhouse Gas Reduction Strategy 2005-2009 The following data sets and reports provide the basis for Council’s biodiversity knowledge: • List of endangered and vulnerable species, endangered ecological communities and key threatening processes. • Threatened flora and fauna species profiles for staff on intranet provide detailed descriptions, photos and diagrams, locations found and where conserved, management and survey issues. • Comprehensive local scale vegetation mapping at a scale 1:8,000. This excludes National parks and state forests and classification is consistent with regional vegetation classifications. • Environmental data layers on Council’s Geographic Information System include local vegetation mapping, acid sulphate soils, threatened species locations (DEC Atlas data), aerial photography, Aboriginal sites (DEC AHIMS). • Flora and fauna species lists (see Appendices 3 and 4). • Flora and fauna survey data for Western COSS (45 flora survey plots). • Comprehensive Vegetation Mapping (50 flora survey plots). • Targeted and systematic fauna surveys (27 survey sites) undertaken for GCC. • Regional Biodiversity Strategy including fauna modelling and regional vegetation mapping (HCCREMS). • Coastal lagoons Data Compilation Study • Brisbane Water Processes Study • Targeted studies for flora Prostanthera junonis, P. askania, for fauna Bush Stonecurlew, Green and Golden Bell Frog, Yellow-bellied Glider. • Specific environmental studies such as for Davistown, Yattalunga, Bensville, Western COSS Investigation • Brisbane Water Estuarine Biodiversity and Estuary Plankton Study. • Specific water quality and riparian management studies. • Bush regeneration plans for Bushcare sites. • Individual site assessments and environmental impact statements for development applications and Council projects.

A - 3.2 Appraisal of biodiversity projects undertaken 2000 – 2004 Council has initiated a number of key projects aimed at reducing impacts on native species, improving conservation measures for native vegetation, increasing community awareness of the importance of native wildlife and bushland areas and improved environmental assessment under its Biodiversity Program. Many of these activities have been across different areas in Council. In addition, many have been collaborative projects with key agencies and community groups. This method recognises that biodiversity conservation requires a broad, strategic and collaborative approach across all land tenures and areas of responsibility. Projects that have been completed or substantially completed in the period 2000 – 2005 as part of the implementation of the Biodiversity Management Program are reviewed below. A - 3.2.1 Gosford Biodiversity Action Plan Council developed a Gosford Biodiversity Management Action Plan in early 2002. This identified high, medium and low priority actions for Council under eight themes. Actions included data collation, environmental management and assessment, education, monitoring and research. The majority of high and medium actions identified in this plan have been implemented (See below). Further details on many of these projects are described in further detail in the following sections. A - 3.2.2 Systematic and Targeted Fauna Biodiversity Surveys 2000/2001 Council commissioned two systematic and targeted fauna surveys as part of the development of the Biodiversity Plan. The aims of the study were to gain an understanding of the range of fauna values present across the various ecosystems in the City and obtain a set of objective data to establish a baseline systematic dataset for ongoing monitoring projects. Twenty seven sites were selected across the City. The first survey was undertaken in late summer-autumn 1999 by the Australian Museum Business Services (2000). The second study was undertaken in winter and spring 2000 by Conacher Travers (2001). The sites selected cover a range of ecosystems on different soil landscapes. Estuarine and beach habitats were not surveyed. The methodology followed the methods established under the Comprehensive Regional Assessment (CRA) vertebrate surveys (NSW NPWS 1999). The major conclusions from the second study were that fauna species richness tended to be higher within wetter habitats associated with gullies and lower in more exposed sandstone ridges. The report found that the denser vegetation types and moister habitats tended to provide habitat for a greater range of amphibians, reptiles, birds and terrestrial mammals. Overall, twelve threatened species were found at 16 of the 27 sites. Generally this correlated with sites that also had a higher number of common species. Habitat types containing older growth forest trees were characterized by the presence of hollow dependent fauna. Fauna species richness was found to be lowest in areas in close proximity to, or isolated by, urban settlement and in areas where connectivity was poor. Edge effects such as weed invasion, refuse dumping and entry of domestic animals were greatest at the sites that were more isolated. Sites that showed greater connectivity to the coastal ridgelands reserves showed moderate to high fauna values. Tall open forest types such as those at MacMasters Beach and Cockrone Lagoon were found to provide specialist habitat for a number of arboreal mammals such as the Yellow-bellied Glider and Greater Glider. Moderately high fauna values were found within swamp forest at Avoca Lake whilst values were generally lower within sites at Somersby and Niagara Park. It was suggested that although connectivity existed to areas such as Biodiversity - Technical Report Page 56
