About BSUD

Designing cities that benefit both people and nature will help to conserve threatened species and improve human wellbeing. By considering biodiversity from the beginning of the planning process, BSUD helps to simplify biodiversity-friendly design, which can then deliver a broad range of nature conservation and liveability outcomes.

The BSUD framework was created by Garrard et al. (2018) to be applied across a range of urban development types. The aim of the framework is to create suburbs that are of net benefit to native species and ecosystems through the provision of essential resources.

BSUD is innovative in the field of sustainable urban development as it focusses on creating onsite gains for biodiversity. By identifying synergies between development and biodiversity objectives, BSUD improves the transparency of decision making and represents a fundamental shift in the way we think about including biodiversity in urban planning.

the building blocks

The 5 Principles of BSUD

1. Maintain or create habitat for target species
2. Facilitate dispersal
3. Minimise disturbance and other threats
4. Facilitate natural processes (such as pollination)
5. Facilitate positive human-nature interactions

The Implementation Framework:

Document Biodiversity Values

Native plants & animals, incl threatened.

Landscape context, including geological & hydrological features, spatial arrangement, and connectivity. Potential threats to biodiversity.

Identify Biodiversity Objectives

Maintain or improve viability of threatened species & ecosystems. Opportunities for rewilding.

Identify BSUD Actions

Considering 5 principles for BSUD.

Seek solutions that address biodiversity & development objectives. Address key threats to biodiversity.

Identify Development Objectives

Building & infrastructure requirements. Population & dwelling targets. Liveability targets.

Assess BSUD

Assess the contribution of BSUD using appropriate metrics: Population viability, occupancy, abundance. Use tools such as PVA & expert elicitation.

Decide

Determine BSUD that best meets biodiversity & development objectives.

Manage trade-offs between objectives using tools such as: Project Prioritisation Protocol and participatory approaches.
