Protecting land mammals requires conserving 11% of Earth to safeguard 10% of their ranges. This global analysis highlights the urgent need for conservation strategies to prevent extinction risks for terrestrial mammals.
Area of Science:
- Conservation biology
- Zoology
- Biodiversity research
Background:
- A significant portion of terrestrial mammal species and populations face extinction risks.
- Factors contributing to risk include rarity, human impacts, and political boundaries.
Purpose of the Study:
- To conduct a global conservation analysis for land mammals.
- To identify priority areas for conservation to preserve mammal biodiversity.
Main Methods:
- Utilized a new global database of land mammals.
- Employed a complementarity analysis to select priority conservation areas.
- Assessed the land area required to protect mammal geographic ranges.
Main Results:
- Approximately 11% of Earth's land surface needs management for conservation.
- This area aims to preserve at least 10% of terrestrial mammal geographic ranges.
- A substantial fraction of mammal populations are at risk.
Conclusions:
- Global conservation efforts must focus on specific land areas to protect mammals.
- A combination of reserve protection and landscape enhancement is necessary.
- Urgent action is needed to address the extinction crisis facing land mammals.
