### Description

LemuRank is an easy-to-use index that identifies and prioritizes key areas for conservation worldwide. It applies a *Spatial Conservation Prioritization* approach at global and regional scales, using 1 km² grid cells as the unit of analysis.

The index integrates multiple factors related to biodiversity and ecosystem services. Values range from 0% to 100%, with higher values corresponding to areas of greater conservation importance. These are zones where preservation is most critical to ensure long-term ecological sustainability.

### What it measures

- Conservation priority at global and regional scale.
- Integration of biodiversity, ecosystem services, and human pressures.
- Relative value of each grid cell (0–100%).

### How to interpret

- **Low values (near 0%):** Lower relative conservation need.
- **High values (closer to 100%):** Highest priority areas for biodiversity and ecosystem service preservation.

### Unit / Scale

Percentage (0–100%).  
Spatial resolution: 1000 m.  
Temporal coverage: 2024.  
Update frequency: Annual.
