Overview

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

Rannoch-rush faces severe decline due to drainage and destruction of its specialized bog habitats for agriculture and peat extraction. Climate change poses an additional threat by altering the hydrological conditions essential for maintaining the acidic, nutrient-poor wetlands this species requires. The species' extremely limited distribution in Scotland makes it particularly vulnerable to local habitat modifications and water table changes.

Threat summary

Habitat

Rannoch-rush is restricted to acidic, nutrient-poor bog pools and shallow waters within Sphagnum-dominated peatlands. It requires permanently waterlogged conditions with stable water tables in oligotrophic wetland systems, typically found in raised bogs and blanket mires.
