Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Cycas siamensis faces severe pressure from overcollection for the horticultural trade, where mature specimens command high prices as ornamental plants. Habitat destruction through agricultural expansion and urban development has fragmented remaining populations across its limited range in Thailand and Cambodia. The species' extremely slow growth rate, taking decades to reach reproductive maturity, makes recovery from population declines particularly challenging.
Habitat
Cycas siamensis inhabits dry deciduous forests and rocky limestone outcrops in Thailand and Cambodia. The species typically grows in well-drained soils on hillsides and forest edges at elevations up to 500 meters.
