Lesson 1: It’s Not Just Business As Usual And A Few More Trees With Claire Wansbury

Short video excerpt


In Lesson 1, Claire Wansbury will introduce you to some concepts and the rest of the course.

The Concept of Biodiversity Net Gain: Claire introduces us to the idea of biodiversity net gain (BNG), a pivotal strategy for ensuring that development projects in England contribute positively to the environment.

Legislation and Policy: We discuss the recent inclusion of BNG in the Environment Act of 2021 and its implications for the Town and Country Planning Act, marking a significant shift towards mandatory environmental responsibility in construction.

Beyond Compliance: Biodiversity net gain isn’t just a tick-box exercise; it represents a harmonious blend of environmental, societal, and economic benefits. We’ll explore why BNG is essential for sustainable development.

Measuring Success: Our guest breaks down the metric-based framework used to evaluate biodiversity net gain, explaining the mitigation hierarchy—avoidance, mitigation, compensation—and the goal of achieving a minimum of a 10% net increase in biodiversity.

Holistic Habitat Design: The conversation will delve into the importance of qualitative measures alongside quantitative ones, emphasising the need for thoughtful habitat design that serves both people and wildlife.

Collaborative Progress: Claire highlights the value of shared experiences and learning in perfecting the application of BNG. As we progress, it’s about building a collective understanding to implement these principles more effectively.

A Vision for the Future: Finally, we look at the broader objective of using BNG, among other tools, to work towards a future where nature isn’t just preserved but is actively enriched by development activities.

Lesson 4: How To Observe Bats As Indicators – Dr. Carol Williams

Short video excerpt

Biodiversity Indicators: Bats are more than just mysterious creatures of the night; they are key indicators of a healthy ecosystem. Carol Williams explains how their presence and diversity reflect the state of biodiversity in Britain.

Britain’s Bat Species: We’ll learn about the 17 unique species of bats in Britain, each with its distinct behaviours and habitats. Understanding these differences is essential for effective conservation.

Legal Protection for Bats: Bats in Britain enjoy legal protection, which extends to their roosts, feeding areas, and movement routes. Carol underscores the importance of this protection for their survival, especially in light of their decline over the past century.

Integrating Conservation in Development: The text presents a three-step approach for incorporating bat conservation into development projects, highlighting the importance of identifying sustenance zones, understanding habitat needs, and mitigating impacts on foraging areas.

Building Resilience: By intersecting core sustenance zones, we can enhance resilience for other bat roosts. Carol shares actionable measures like creating green corridors, preserving flight paths, and employing sensitive lighting.

Enhancing Roosting Potential: Discover how strategies such as installing bat boxes can improve roosting opportunities. The show discusses the mitigation hierarchy, which emphasises avoiding and minimising impacts before compensating for them through biodiversity net gain.

Biodiversity Net Gain Concept: The episode delves into how biodiversity net gain is essential for ensuring that bat populations not only survive but thrive in the face of development. This concept is vital for species recovery and enhancing the quality of life for all species, including humans.
