Neocalyptrocalyx nectarius

Declining

Overview

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

Neocalyptrocalyx nectarius faces severe pressure from deforestation and agricultural expansion across its limited range in Southeast Asian tropical forests. Mining activities and infrastructure development have fragmented remaining habitat patches, while climate change threatens the specific microclimatic conditions this species requires. The species' narrow ecological niche and small population size make it particularly vulnerable to habitat degradation and environmental fluctuations.

Threat summary

Habitat

This species inhabits primary and secondary tropical rainforests, typically found in the understory and mid-canopy layers where it depends on specific microhabitat conditions. It shows preference for areas with high humidity and dense vegetation cover, often associated with stream valleys and forest edges.
