European biodiversity laws use species-specific price lists for fauna compensation, but these values are often unclear. Our study reveals hidden biases, showing mammals and birds are valued higher, influenced by traits and protection status.
Area of Science:
- Conservation Law and Policy
- Ecological Economics
- Biodiversity Valuation
Background:
- European biodiversity legislation utilizes species-level price lists for fauna to determine compensation for ecological damage.
- Current valuation methods lack transparency and robust justification, leading to concerns regarding fairness, consistency, and ecological relevance.
Purpose of the Study:
- To investigate the patterns and influencing factors behind monetary compensation values assigned to fauna in European biodiversity legislation.
- To uncover the implicit criteria guiding regulatory decisions in biodiversity damage compensation.
Main Methods:
- Analysis of a comprehensive dataset encompassing 9,971 species across 24 European countries.
- Statistical examination of species-level monetary values in relation to biological traits and taxonomic groups.
- Identification of factors such as generation length and protection status influencing species valuation.
Main Results:
- Species-level monetary values are significantly influenced by implicit biological traits and taxonomic biases.
- Mammals and birds receive disproportionately higher compensation values compared to other fauna.
- Key biological traits, including generation length and legal protection status, demonstrably impact species valuation.
Conclusions:
- Regulatory decisions in biodiversity compensation are shaped by hidden, non-uniform criteria.
- Current valuation practices may not fully align with ecological relevance or conservation priorities.
- Recommendations include integrating systematic, science-based criteria and fostering collaboration between conservation scientists and legal experts.
