The biggest cause was storms, floods and other natural causes (5%), after which forest can grow back. Almost none of it was deforestation, meaning forest cleared for good.

What is the tree count in Puno?

How are Puno's air quality and tree cover measured?
Air quality comes from ground monitoring stations via OpenAQ where one reports nearby, and otherwise, as here, from the Open-Meteo / CAMS model, which may differ from street-level monitors. Tree cover is measured from Sentinel-2 L2A (ESA Copernicus) via Earth Search satellite imagery at 10 m detail across a 2 km radius around Urb Barrio Porteño; the tree count is an estimate derived from that cover.
