Question 1

What is a Biodiversity Development Assessment Report (BDAR)?

Accepted Answer

A BDAR is a formal assessment under the NSW Biodiversity Conservation Act 2016 that evaluates the potential impacts of a proposed development on native vegetation, threatened species, and their habitats. It must be prepared by a BAM-accredited assessor and is required when development triggers the Biodiversity Offset Scheme thresholds.

Question 2

When do I need a flora and fauna assessment in NSW?

Accepted Answer

A flora and fauna assessment is typically required by your local council as part of a Development Application (DA) when your proposed development may impact native vegetation, threatened species, or ecological communities. This requirement comes from the NSW Environmental Planning and Assessment Act 1979.

Question 3

What triggers the NSW Biodiversity Offset Scheme?

Accepted Answer

The Biodiversity Offset Scheme is triggered when a development exceeds area clearing thresholds based on the minimum lot size of the property, or when the land is identified on the Biodiversity Values Map. The area thresholds range from 0.25 hectares for smaller lots to 1 hectare for lots over 40 hectares.

Question 4

How much does an ecologist cost in Sydney and NSW?

Accepted Answer

Ecological consulting fees in NSW vary depending on the type and complexity of assessment. A basic flora and fauna assessment for a small residential DA may start from around $3,000-$5,000, while a full BDAR for a larger development can range from $8,000 to $30,000 or more.

Question 5

What is the difference between a BDAR and a Flora and Fauna Assessment?

Accepted Answer

A Flora and Fauna Assessment (FFA) is a broader ecological assessment under the EP&A Act using the Five-Part Test of Significance. A BDAR is a more rigorous, standardised assessment under the Biodiversity Conservation Act 2016 using the Biodiversity Assessment Method (BAM), required when the Biodiversity Offset Scheme is triggered.

Question 6

How long does an ecological assessment take?

Accepted Answer

A standard flora and fauna assessment typically takes 3-6 weeks. BDARs generally take 6-12 weeks due to more intensive survey requirements. Targeted threatened species surveys may require seasonal timing and can take several months. Contact us early in your project planning.

Question 7

What is PCT vegetation mapping?

Accepted Answer

PCT (Plant Community Type) mapping identifies and classifies native vegetation on a site using the NSW BioNet Vegetation Classification system. Each PCT is defined by its characteristic plant species composition, structure, and landscape position. PCT identification is essential for BDAR assessments.

Question 8

Do I need an ecologist for my development application?

Accepted Answer

You likely need an ecologist if your development site contains native vegetation, is near bushland or waterways, is on or near land mapped as having biodiversity values, or if your local council requires an ecological assessment. Most councils in Sydney, Hunter, Illawarra, and Central Coast regions require ecological input.
