A nature-based conservation framework that aligns opportunities for bird biodiversity, climate mitigation, and human...

Area of Science:

• Ecology
• Conservation Science
• Climate Change Mitigation

Background:

• Nature-based solutions (NbS) are crucial for addressing the climate crisis and enhancing biodiversity and human well-being.
• Identifying optimal locations for NbS is essential for maximizing their effectiveness and co-benefits.

Purpose of the Study:

• To map critical habitats for birds under climate change and identify carbon stocks/sinks in the US.
• To assess the alignment of these areas with human well-being and land-dependency factors.
• To pinpoint High Priority NbS areas, especially those with irrecoverable carbon, for focused conservation.

Main Methods:

• Spatial analysis integrating bird habitat suitability, carbon data, and human well-being indicators.
• Mapping of protected lands and identification of unprotected priority areas.
• Assessment of co-occurrence between priority areas and local communities.

Main Results:

• Only <3% of protected US lands align with priorities for birds, carbon, and human well-being.
• 71% of identified priority areas (312 million acres) lack legal protection.
• 80% of priority areas overlap with communities having cultural and socioeconomic ties to the land.

Conclusions:

• Targeting unprotected priority areas for NbS conservation and restoration is vital for equitable climate benefits.
• NbS can guide conservation investments toward marginalized communities and protect climate-critical biodiversity habitats.
• Collaborative approaches with local communities are imperative for successful NbS outcomes.
