Implication

Analysis estimates annual costs to meet biodiversity goals, highlighting significant funding gaps and needs.

Key Points

  • This analysis aims to estimate the financial costs required to meet global biodiversity conservation targets and assess current funding levels.
  • Estimated costs of reducing extinction risk for globally threatened bird species and nonavian species.
  • Calculated financial needs for protecting and managing significant terrestrial conservation sites.
  • Evaluated current funding levels against estimated costs.
  • Estimated annual cost for bird species is between $0.875 and $1.23 billion, with only 12% currently funded.
  • Including nonavian species raises annual costs to $3.41 to $4.76 billion.
  • Total annual cost for managing Important Bird Areas is $65.1 billion, increasing to $76.1 billion when including sites for other taxa.
