Understanding the NSW Biodiversity Offsets Scheme: A Practical Guide for Developers and Landholders

If you are planning a development project in New South Wales, there is a strong chance you will encounter the NSW Biodiversity Offsets Scheme (BOS). Established under the Biodiversity Conservation Act 2016, the scheme is designed to ensure that unavoidable impacts on biodiversity are offset by securing and managing land with equivalent or greater ecological value elsewhere. For developers, landholders, and project managers, understanding how this scheme works is essential to keeping your project on track and avoiding costly delays.

What Is the NSW Biodiversity Offsets Scheme?

The Biodiversity Offsets Scheme is the framework through which NSW manages the impact of development on native plants, animals, and ecological communities. When a development is likely to have a significant impact on biodiversity, the proponent is required to offset that impact by retiring biodiversity credits. These credits are generated by landholders who commit to long-term conservation management on their properties through Biodiversity Stewardship Agreements.

The scheme operates as a market-based system. Developers who need to offset their impacts purchase credits from stewardship site holders or pay into the Biodiversity Conservation Fund (BCF). The type and number of credits required depends on the specific biodiversity values affected and is determined through a Biodiversity Development Assessment Report (BDAR).

When Does the Biodiversity Offsets Scheme Apply?

The scheme is triggered in several circumstances. Understanding these triggers is critical for early project planning.

Firstly, it applies when the Biodiversity Offsets Scheme Threshold is exceeded. This threshold is based on the area of native vegetation to be cleared and varies depending on the minimum lot size under the relevant Local Environmental Plan (LEP). For properties with a minimum lot size of less than 1 hectare, the threshold is 0.25 hectares. For lots between 1 and 40 hectares, it is 0.5 hectares. For lots of 40 hectares or more, the threshold is 1 hectare.

Secondly, the scheme applies when a development is likely to significantly affect threatened species or ecological communities, as determined by the Five-Part Test of Significance under Section 7.3 of the Biodiversity Conservation Act 2016. Thirdly, the scheme is triggered when a development is proposed on land identified on the Biodiversity Values Map. Finally, the consent authority or the proponent may choose to opt in to the scheme voluntarily.

How Do Biodiversity Credits Work?

There are two types of biodiversity credits under the scheme. Ecosystem credits relate to impacts on ecological communities and their associated species. Species credits are required for impacts on individual threatened species that cannot be reliably predicted by their habitat alone and require targeted surveys.

The number and type of credits a project needs to retire is calculated through the Biodiversity Assessment Method (BAM), which is applied by an accredited assessor during the preparation of a BDAR. The BAM is a standardised methodology that quantifies biodiversity values at the development site and determines the offset obligation.

Options for Meeting Your Offset Obligation

Once a BDAR establishes the credit requirement, there are three primary ways to meet the offset obligation. You can purchase credits on the open market from holders of Biodiversity Stewardship Agreements, which are registered on the public credit register. Alternatively, you can make a payment into the Biodiversity Conservation Fund, managed by the Biodiversity Conservation Trust (BCT), at the published credit price. Finally, you may be able to secure your own offset site by entering into a Biodiversity Stewardship Agreement on suitable land you own or can access.

Opportunities for Landholders: Biodiversity Stewardship Agreements

For NSW landholders, the Biodiversity Offsets Scheme presents a significant opportunity. If your property contains high-quality native vegetation or habitat for threatened species, you may be eligible to establish a Biodiversity Stewardship Site. This involves entering into a perpetual agreement with the BCT to manage the land for conservation. In return, you generate biodiversity credits that can be sold on the open market, providing a long-term income stream while contributing to conservation outcomes.

The process requires an accredited assessor to prepare a Biodiversity Stewardship Site Assessment Report (BSSAR) using the BAM. This assessment quantifies the biodiversity values of the proposed stewardship site and determines the number and type of credits that can be generated.
