Handroanthus arianeae

Declining

Overview

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

Handroanthus arianeae faces severe pressure from deforestation and habitat conversion throughout its limited range in the Atlantic Forest of Brazil. The species is particularly vulnerable due to its restricted distribution and the ongoing fragmentation of its forest habitat for agriculture and urban development. Selective logging targeting valuable timber species in the Bignoniaceae family poses an additional direct threat to remaining populations.
