Cycas collina

Cycas collina is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Cycas collina faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development across its limited range in the Philippines. Mining activities and quarrying operations have directly destroyed several known populations, while overcollection for horticultural trade has further reduced wild numbers. The species' extremely slow growth rate and limited reproductive capacity make recovery from these pressures particularly challenging.

Cycas collina occurs in China, and Vietnam. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.

The main threats to Cycas collina are 2.1, 4.1, 5.3, and ai-1. The full IUCN-classified threat record for this species is detailed on the species page.
