Tmeticus affinis

Unknown

Overview

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

Tmeticus affinis faces significant pressure from habitat degradation in its specialized coastal and wetland environments. Urban development and agricultural expansion have reduced available nesting sites, while pollution from agricultural runoff affects the aquatic invertebrates that form its primary food source. Climate change-induced sea level rise threatens the low-lying coastal areas where this species predominantly occurs.

Threat summary

Habitat

This species inhabits coastal wetlands, salt marshes, and adjacent grasslands, typically within 5 kilometers of the shoreline. It shows a strong preference for areas with dense vegetation cover and access to shallow water bodies that support abundant invertebrate prey.
