Section 2 - Statutory StatementsEnvironmental Programs Summary - cont.Aquatic and Marine Biodiversity• High nutrient levels including from on-site waste-water systems into waterways• Illegal dumping of rubbish in aquatic areas• Spread of invasive flora and fauna• Stormwater discharges reducing water quality• Anchoring and ballast water from boats spreading weeds and exotic species of fauna• Moorings damaging sea-grass beds• Increasing frequency and intensity of storm events• Replacement of swimming nets• Climate change impacts including sea level rise; increased intrusion of salt water vegetation intofreshwater ecosystems in coastal area; altered rainfall and runoff patterns; and increased occurrenceof eutrophication of lagoons, wetlands and estuariesRegional response to biodiversity issuesBiodiversity issues were addressed as part of the SHOROC SoE community consultation meeting held on6 August 2009. Participants in the consultation were asked to identify priority issues of concern to themrelating to biodiversity, and to work together to make recommendations for addressing these issues. Thepriority biodiversity issues and recommendations identified are provided below:IssueRetain/improve/protectareas of remaining nativevegetationLack of <strong>Council</strong> ability toenforce environmentalconditionsRecommendation• <strong>Council</strong>s to survey, identify and rank remaining natural areas on bothpublic and private land, including consideration of climate change• Develop ways to protect biodiversity through Plans of Management, LocalEnvironment Plans and Development Control Plans• Implement targeted education programs about the significance and valueof natural areas• Improve ranking and identification of natural areas to enable appropriatezoning of land• Allocate resources in councils to improve enforcement of environmentalconditions often attached to developments e.g. restrictions relating to catsand dogs<strong>Pittwater</strong> Programs - BiodiversityEradication of Bitou Bush and Boneseed from Sand Dunes, Headlands and SeacliffsThis initiative is part of the <strong>NSW</strong> Threat Abatement Plan (TAP) – ‘Invasion of native Plant Communitiesby Chrysanthemoides Monilifera (Bitou Bush and Boneseed) Project funded by the Sydney Metropolitanand Hawkesbury Nepean Catchment Management Authorities; a 5 year project which commenced in2007/08.The project aims to restore endangered ecological communities (e.g. Themeda Grasslands and LittoralRainforest) on coastal cliffs and headlands to a healthy condition by removing invasive weeds such asBitou bush, Boneseed and Asparagus Fern and facilitate natural regeneration. Asparagus Fern will also betargeted where it occurs within the Bitou infestation as it is envisaged that Asparagus Fern will proliferateafter Bitou removal and hence threaten endangered ecological communities if it too is not controlled.Restoration of Coastal Shale Heath and Littoral Rainforest at Little Head & Norma ParkLittle Head Reserve and Norma Park Reserve are composed of Coastal Shale Heath, a forest type verydifferent from what is found in the Sydney basin area, which is mostly sandstone. Coastal Shale Heath isfound intermixed with Littoral Rainforest on several headlands of the <strong>Pittwater</strong> peninsula. <strong>Pittwater</strong> <strong>Council</strong>,the <strong>NSW</strong> Environmental Trust, and Bushcare Volunteers are engaged in a joint project to help restore andprotect this endangered ecological community in <strong>NSW</strong>. This project is also made possible through thefinancial support of the local community.<strong>Pittwater</strong> Spotted Gum Forest Restoration<strong>Pittwater</strong> Spotted Gum Forest is listed under the Threatened Species Conservation Act 1995 as anendangered ecological communitY. <strong>Pittwater</strong> Spotted Gum Forest is home to a large number of local nativeanimals, including many bird species and the endangered Squirrel Glider.Community workshops revealed that the community values and identifies with the “leafy” look of <strong>Pittwater</strong>.The Spotted Gums and other Eucalyptus trees make up much of this valued “green look”. Over 70% of<strong>Pittwater</strong> Spotted Gum Forest is found on private land, with only 30% existing in <strong>Council</strong> bushland reserves.<strong>Council</strong> will continue to work with local property owners to ensure this forest community is going to bearound for generations to come. <strong>Council</strong> has undertaken works to help restore and protect the natural stateof the <strong>Pittwater</strong> Spotted Gum Forest in critical areas, especially in public reserves.38
