Notholebias fractifasciatus

Declining

Overview

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

Notholebias fractifasciatus faces severe threats from habitat destruction as its extremely limited wetland habitats are drained for agricultural development and urban expansion. The species' restricted range makes it particularly vulnerable to water pollution from agricultural runoff and domestic waste, which degrades the water quality essential for its survival. Climate change poses an additional threat through altered precipitation patterns that could dry up the seasonal pools this killifish depends upon for breeding.

Threat summary
