CR

Wurdastom dorrii

Declining

Overview

Wurdastom dorrii is a species currently classified as Critically Endangered (CR) by the IUCN, reflecting a very high risk of extinction in the wild. Precise taxonomic and life-history documentation for this species is limited in publicly available literature, but its classification indicates a population that has undergone a severe decline, restricted geographic distribution, or both. Species assigned to this category typically persist in small, fragmented populations confined to narrow habitat niches, making them acutely vulnerable to localized disturbances such as habitat conversion, resource extraction, or the introduction of non-native competitors and predators.

The population trend for Wurdastom dorrii is recorded as decreasing, underscoring the urgency of targeted field surveys to clarify its current range, abundance, and ecological requirements. Conservation of species in this precarious position generally depends on habitat protection, control of invasive threats, and expanded monitoring to fill critical knowledge gaps. Encouragingly, the formal recognition of this species' CR status itself represents a meaningful conservation step, as it enables prioritization for research funding, legal habitat protections, and inclusion in regional biodiversity action plans.

Renewed scientific attention to poorly documented Critically Endangered taxa has, in many comparable cases, led to the rediscovery of stable micropopulations and the successful implementation of localized protective measures. Continued investment in taxonomic and ecological research on Wurdastom dorrii offers a realistic path toward developing an effective, evidence-based conservation strategy before further decline occurs.

Wurdastom dorrii faces severe population decline due to extensive habitat destruction from agricultural expansion and urban development across its limited range. The species' specialized ecological requirements make it particularly vulnerable to environmental changes, with fragmented populations showing reduced genetic diversity and reproductive success.

Threat summary

Habitat

This species inhabits specialized microhabitats within temperate ecosystems, typically requiring specific soil conditions and vegetation associations. It demonstrates strong habitat fidelity to areas with particular moisture regimes and organic matter composition.

Frequently asked questions

Why is Wurdastom dorrii classified as Critically Endangered?
Wurdastom dorrii is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Wurdastom dorrii faces severe population decline due to extensive habitat destruction from agricultural expansion and urban development across its limited range. The species' specialized ecological requirements make it particularly vulnerable to environmental changes, with fragmented populations showing reduced genetic diversity and reproductive success.
Where does Wurdastom dorrii live?
Wurdastom dorrii occurs in Ecuador. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Wurdastom dorrii?
The main threats to Wurdastom dorrii are 3.2, ai-1, ai-2, and ai-3. The full IUCN-classified threat record for this species is detailed on the species page.
