Overview

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

Northern Jacob's-ladder faces severe pressure from climate change as warming temperatures push suitable alpine and arctic habitats to higher elevations and latitudes. The species' fragmented populations are increasingly isolated by habitat loss from mining activities and infrastructure development in its northern range. Small population sizes make individual colonies vulnerable to local extinctions from extreme weather events and human disturbance.
