Hortia superba

Declining

Overview

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

Hortia superba faces severe pressure from deforestation and agricultural expansion throughout its limited range in Brazil's Atlantic Forest. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, as remaining forest patches become increasingly isolated. Mining activities and urban development further reduce available habitat, while the slow growth rate typical of Rutaceae family trees limits the species' ability to recover from population losses.

Threat summary

Habitat

Hortia superba is endemic to the Atlantic Forest (Mata Atlântica) of southeastern Brazil, where it grows in humid montane forests at elevations between 800-1,500 meters. The species requires well-drained soils and partial canopy cover, typically occurring in secondary growth forests and forest edges.
