Cycas nongnoochiae

Declining

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Cycas nongnoochiae faces severe pressure from habitat destruction as limestone karst forests in Thailand are cleared for agriculture and urban development. The species is further threatened by overcollection for the horticultural trade, where mature specimens command high prices due to their rarity and ornamental value. Climate change poses an additional long-term threat by altering the specific microclimate conditions required in its limestone cave and cliff habitats.

Threat summary

Habitat

This cycad is endemic to limestone karst formations in eastern Thailand, specifically growing on steep limestone cliffs, cave entrances, and rocky crevices. It thrives in the unique microclimate created by these geological formations, requiring well-drained alkaline soils and partial shade provided by the karst topography.
