Mannophryne neblina

Declining

Overview

The Rancho Grande rocket frog also or known Rancho Grande poison-arrow frog and Aragua collared frog is a species of frog in the family Aromobatidae. It is endemic to Venezuela.

Mannophryne neblina faces severe threats from habitat destruction due to mining activities and agricultural expansion in the Venezuelan Guiana Shield. The species' extremely restricted range on tepuis makes it particularly vulnerable to localized environmental changes and climate shifts that could alter the unique cloud forest conditions it requires. Illegal gold mining operations have directly impacted stream habitats essential for this poison dart frog's reproduction and survival.

Threat summary

Habitat

This poison dart frog inhabits cloud forests and montane streams on tepuis (table mountains) in the Venezuelan Guiana Shield, typically at elevations between 1,200-2,000 meters. The species requires pristine freshwater streams with rocky substrates for breeding and dense cloud forest vegetation that maintains high humidity levels year-round.
