National red listing beyond the 2010 target

Area of Science:

• Conservation Science
• Biodiversity Monitoring
• Environmental Policy

Background:

• National Red Lists (NRLs) are vital for tracking biodiversity status and trends, supporting international conservation targets like the 2010 Biodiversity Target.
• NRL data is increasingly important for national conservation priority setting and climate change adaptation strategies.
• Global assessments of NRL coverage are needed to identify gaps and guide future conservation investments.

Purpose of the Study:

• To conduct a global review of National Red Lists (NRLs) in 109 countries.
• To analyze geographic and taxonomic gaps in NRL coverage.
• To examine correlations between NRL comprehensiveness, GDP, and vertebrate species richness.

Main Methods:

• Global review of National Red Lists (NRLs) across 109 countries.
• Analysis of geographic and taxonomic gaps in NRL coverage.
• Statistical correlation analysis between NRL data, GDP, and vertebrate species richness.

Main Results:

• Significant geographic gaps in NRL coverage were identified in Oceania, middle Africa, the Caribbean, and western Africa.
• Major taxonomic gaps exist for invertebrates, fungi, and lichens.
• NRL comprehensiveness positively correlated with GDP and negatively with vertebrate species richness, indicating wealthier nations have better coverage despite lower biodiversity.

Conclusions:

• Regions with the highest biodiversity and greatest conservation needs often receive the least attention due to financial limitations.
• Improving NRL coverage requires targeted projects for underrepresented taxa/regions and capacity building for countries to develop their own lists.
• Enhanced knowledge transfer within and across regions is a priority for future investment in biodiversity monitoring.
