One of the major concerns about the NSW government’s biodiversity laws is the fundamental flaws in the Biodiversity Offsets Scheme, which will lead to the widespread clearing of remnant bushland in the Greater Sydney area, in return for developers' cash payments – see STEP Matters Issue 191. The application of these payments is unlikely to make up for the biodiversity that is lost. Several groups are so concerned that they have written a joint open letter to the premier. It is not only environment groups involved. Others are the Heart Foundation, the Institute of Landscape Architects and the National Trust.

The letter (see below) calls for action from the government to make the rhetoric a reality that the legislation will improve biodiversity within Sydney. Members of the general public are invited to sign the letter.

Dear Premier

With Sydney’s population projected to grow to 6.4 million by 2036 and the worsening climate change-related urban heat island effect, we write to urge you to ensure that adequate levels of green space are provided to all Sydney-siders and Sydney’s unique bushland and wildlife is protected.

Sydney-siders highly value access to a range of formal and informal green spaces – trees, bushland, parks and sporting fields. This is borne out in previous public surveys and the strong community reaction whenever public green space is sold-off or alienated for development.

Extensive research, both in Australia and overseas, clearly shows that the environmental, social, spiritual and economic benefits of green spaces are irrefutable. Green spaces cool our city, reduce energy costs, increase property values, promote healthy lifestyles, improve air and water quality, reduce net carbon emissions, prevent stormwater runoff and provide important wildlife habitat.

Sydney's green spaces also play a key role in the health of Sydney's iconic blue spaces. For example, the revitalisation and resilience of Greater Sydney's six major river systems – Hacking, Georges, Cooks, Parramatta, Nepean and Hawkesbury, as well as Botany Bay and Sydney Harbour depends on the health and connectivity of the surrounding vegetation.

Despite these benefits, current NSW government policy and legislation is failing to protect Sydney’s green spaces as these are actively being depleted by clearing and alienation for grey urban and industrial infrastructure development. The Total Environment Centre’s SOS Green Spaces map highlights over 70 green spaces currently at risk of destruction. This includes peri-urban areas undergoing rapid development and the impacts of major transport infrastructure projects such as the South East Light Rail and WestConnex. This deteriorating situation must be addressed as a matter of urgency.

A Plan for Growing Sydney Direction 3.2 aims 'to create a network of interlinked, multipurpose open and green spaces across Sydney' also known as the Green Grid. This concept is also supported by the work of the Greater Sydney Commission. However, specific actions, policies, legislative changes and funding are required to shift this concept from rhetoric to reality.

As key stakeholders representing a wide range of interests and expertise about urban green spaces, we urge you to:

• Assign responsibility for planning, implementing and monitoring Sydney’s green spaces to an independent body with the mandate, skills, funding and resources to achieve a comprehensive network of formal and informal green spaces designed to maximise benefits to Sydney-siders and protect Sydney's unique bushland and wildlife in the long-term.
• Prevent the clearing of bushland in the Greater Sydney area unless strict like-for-like offsets can be located and protected in perpetuity within the close vicinity of the bushland being cleared (note: under the government’s current draft Biodiversity Conservation Regulation 2017, the proposed Biodiversity Offsets Scheme will lead to widespread clearing of Sydney’s remnant bushland, including threatened species habitat, particularly in Western Sydney).
• Prevent the alienation of community and Crown land, as well as removal of the tree canopy, from Sydney’s green space network.

Sydney's green spaces are a vital component of its liveability and resilience as a city. Your positive action in protecting and enhancing our green spaces would strengthen your leadership in Australia’s much-loved and admired iconic first city, for current and future generations.

We, the sixteen signatories to this open letter look forward to an opportunity to discuss this important issue further with you.
