Mannophryne speeri

Local name: Speer’s Collared Frog

Declining

Overview

Mannophryne speeri, or Speer's collared frog, is a frog in the family Aromobatidae. It has been found in the Sierra de Portuguesa in Lara, Venezuela.

Mannophryne speeri faces severe threats from habitat destruction due to agricultural expansion and urban development within its extremely limited range in Venezuela's coastal mountains. The species' restriction to small, isolated cloud forest fragments makes it particularly vulnerable to environmental changes and human encroachment. Mining activities and infrastructure development have further fragmented the remaining suitable habitat, while climate change poses additional risks to the specialized montane ecosystems this frog depends upon.

Threat summary

Habitat

This species inhabits montane cloud forests and humid forest edges in the Cordillera de la Costa of northern Venezuela, typically at elevations between 800-1,500 meters. It requires areas with consistent moisture, dense vegetation cover, and suitable breeding sites near streams or temporary water bodies within these specialized high-altitude ecosystems.
