Overview

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

Werner's Largescale Lizard faces significant pressure from deforestation and agricultural expansion throughout its limited range in the northern Andes. Mining activities and infrastructure development have fragmented its cloud forest habitat, while climate change threatens to shift suitable temperature and humidity zones upslope beyond the species' elevational range. The lizard's specialized habitat requirements and small population size make it particularly vulnerable to these ongoing environmental changes.

Threat summary

Habitat

This species inhabits montane cloud forests and humid tropical forests at elevations between 1,200-2,400 meters in the northern Andes. It requires areas with high humidity, dense vegetation cover, and stable microclimatic conditions typical of undisturbed cloud forest ecosystems.
