Impact & Risk Assessments The project requires altering river flows and clearing forested Key biodiversity actions include:
land, potentially posing significant risks to land habitat.
Identify locations with high biodiversity value and quantify biodiversity impact metrics.
To mitigate these impacts, TNB has implemented several Naturalizing Detention Ponds
Implementing Biodiversity Action Plans (BAPs) biodiversity measures: Ponds built for stormwater management are repurposed with fish and aquatic plants,
forming vibrant ecosystems on-site.
Tailor site-specific strategies to address identified potential impact according to the
mitigation hierarchy to support meeting biodiversity goals. Wildlife Monitoring
