Among Flowering Plants, Thousands of Evolutionary Oddities at Risk of Extinction
Abatify Summary
Nature & Climate Perspective
**The extinction of ancient flowering plant lineages undermines the genetic resilience and structural complexity essential for long-term carbon sequestration in LULUCF projects. **
- Loss of rare evolutionary lineages disrupts specialized pollinator networks, potentially collapsing the biodiversity co-benefits required for high-quality nature-based solutions (NbS).
- Ancient plant species often hold unique genetic blueprints for drought and pest resistance, which are critical for the climate adaptation and carbon permanence of forest biomes.
- The degradation of these 'evolutionary oddities' reduces the functional diversity of ecosystems, leading to less stable Net Primary Productivity (NPP) in protected areas.
Market & Policy Outlook
**Biodiversity loss is increasingly categorized as a material financial risk, forcing a shift toward ICVCM-aligned credits that provide verifiable sustainable development impacts beyond simple carbon accounting. **
- Projects failing to protect rare lineages may fall short of the ICVCM Core Carbon Principles (CCPs) regarding 'Sustainable Development Benefits,' potentially leading to a 'biodiversity discount' in market pricing.
- Emerging Article 6.4 frameworks and the Taskforce on Nature-related Financial Disclosures (TNFD) are expected to mandate more rigorous monitoring of species richness to avoid corporate greenwashing claims.
- The integration of biodiversity metrics into SBTi-validated targets is creating a new demand for 'Nature Positive' credits, where ancient lineage preservation acts as a high-integrity signal for institutional investors.
