Overview

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

Wiegmann's tree iguana faces mounting pressure from habitat destruction as agricultural expansion and urban development fragment its native forest ecosystems across Argentina and Chile. Climate change poses an additional threat through altered precipitation patterns and temperature regimes that affect the species' thermoregulation and breeding cycles. Collection for the pet trade has historically impacted local populations, though this pressure has decreased in recent years.
