Digital Mapping Reveals Hidden Crisis for Andean Puya Plants

In the high Andes, the striking Puya plants face a silent crisis. A comprehensive new assessment of all 229 species in this genus has confirmed they are highly threatened by human activities like agriculture, mining, and construction.

Currently, the official International Union for Conservation of Nature (IUCN) Red List has only formally evaluated 83 of these species. To get a complete picture, researchers built a new database and used two different geospatial tools, GeoCAT and ConR, to analyse the entire genus.

The results were stark. One tool placed every single species into a risk category, while the other identified 145 as threatened and flagged 52 as 'Data Deficient', meaning we lack sufficient information. This research highlights how crucial it is to use multiple methods for assessment and to prioritise further botanical exploration. With a clearer view of the widespread risk, specific conservation strategies can now be developed to protect each unique species before it is too late.
