Pilocarpus sulcatus

Declining

Overview

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

Pilocarpus sulcatus faces severe pressure from deforestation and habitat fragmentation across its Atlantic Forest range in Brazil. The species is particularly vulnerable due to its limited distribution and slow growth rate, making population recovery difficult once local populations are eliminated. Commercial harvesting for pharmaceutical compounds, particularly pilocarpine used in glaucoma treatment, has historically placed additional pressure on wild populations.

Threat summary

Habitat
