Palo Overo

Chloroleucon chacoense

Unknown

Overview

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

Palo Overo faces severe pressure from agricultural expansion and cattle ranching throughout the Gran Chaco region, where its dry forest habitat is being rapidly converted for soybean cultivation and pastureland. Selective logging for its valuable timber compounds the threat, as the species produces high-quality wood prized for construction and furniture. Climate change is intensifying drought conditions in its already arid habitat, reducing regeneration success and increasing tree mortality rates.

Habitat

Palo Overo is endemic to the dry Chaco forests of northern Argentina, Paraguay, and southeastern Bolivia, thriving in semi-arid woodlands with sandy and clay soils.
