Briefings

A new Nature study using iNaturalist data predicts that nearly 1,000 cactus species will lose significant habitat by 2100 due to rising temperatures and droughts. Researchers found that over a quarter of species could lose at least 80% of their habitat, with some suffering from sublethal effects like reduced flowering rather than immediate death. Conservation experts warn that while some species may migrate north, many cannot survive in current climates and require relocation to botanical gardens for protection.

Key points

• Nearly 1,000 cactus species face habitat loss by 2100 due to rising temperatures and droughts.
• Over a quarter of species could lose at least 80% of their habitat by 2100.

Context

This research analyzes cactus resilience using citizen science data from iNaturalist, contrasting public perception of drought tolerance with scientific reality. The study highlights how climate change threatens desert ecosystems through heat stress and water scarcity, requiring conservation strategies for species relocation.

Limitations

Data relies on iNaturalist observations with potential sampling gaps. Future predictions remain uncertain and depend on continued climate modeling accuracy. Some specific extinction events like the Key Largo tree cactus are noted as historical examples rather than current forecasts.
