Global Pasture Watch - Annual buffalo density layers at 1-km for 2000–2022 (including 95% prediction interval)

Global annual layers of buffalo density at 1-km spatial resolution convering the period of 2000–2022. The layers were produced using harmonized and used as reference data (55,336 census polygons and 313,604 individual data entries), random forest predictive models and a large stack of multi-source harmonized gridded/raster spatial layers (128 individual raster spatial layers harmonized at 1 km spatial resolution). 

Raster cell values represent heads km2 including:

• Mean predicted values (_m_)
• Upper prediction interval based on 97.5th percentiles (_p.975_)
• Lower prediction interval based on 2.5th percentiles (_p.025_)

Based on 95% probability quantiles, prediction intervals are relatively wide; therefore, for a more effective use, we recommend converting them to standard deviation by dividing the range (p.975 - p.025) by four.

Raw/Uncalibrated headcounts are also provided and were computed by multiplying the density values by the actual area of potential land for livestock production.
