Leproplaca proteus

Härjedalsorangelav (Leproplaca proteus) is critically endangered primarily due to its extremely limited distribution and vulnerability to habitat degradation. This lichen species faces severe threats from air pollution, climate change effects on its specialized substrate requirements, and potential habitat loss from human activities in its restricted range.

Harpactea hombergi

Harpactea hombergi faces severe population declines primarily due to habitat destruction and fragmentation of its specialized cave and rocky crevice environments. Urban development, quarrying activities, and changes in groundwater levels have significantly reduced the availability of suitable microhabitats this endemic spider requires for survival.

Rosa tomentosa

Rosa tomentosa faces severe population declines due to habitat loss from agricultural expansion and urban development, particularly affecting its specialized shrubland and woodland edge habitats. Hybridization with other Rosa species and invasive plant competition further threaten the genetic integrity and survival of remaining populations. Conservation status may vary by region or assessment authority.

Oxyptilus ericetorum

Oxyptilus ericetorum is declining primarily due to habitat loss and degradation of heathland and moorland ecosystems across its range. Agricultural intensification, urban development, and changes in traditional land management practices have significantly reduced the availability of suitable breeding and feeding habitats for this specialized plume moth.

Acaulon mediterraneum

Acaulon mediterraneum faces severe threats from habitat destruction and degradation of its specialized Mediterranean coastal environments. Urban development, agricultural expansion, and climate change are rapidly reducing the availability of suitable sandy and rocky substrates where this moss species can establish and persist.

Psychoides verhuella

Asplenium scolopendrium

Hart's-tongue fern faces significant population declines primarily due to habitat loss and degradation from agricultural intensification, urban development, and quarrying activities that destroy its specialized limestone habitats. Climate change and increased drought frequency further threaten this moisture-dependent species, while invasive plant species compete for suitable growing sites in its remaining fragmented populations.

Hydaticus aruspex

The Haruspex Predaceous Diving Beetle faces severe threats primarily from habitat destruction and water pollution in its limited freshwater environments. Agricultural runoff, urban development, and water extraction have degraded the quality of ponds and streams where this species depends for survival and reproduction.

Otidea leporina

Otidea leporina faces significant decline due to habitat loss from deforestation and land conversion, particularly affecting the old-growth and mature forest ecosystems it depends on. Climate change is altering precipitation patterns and temperature regimes that are critical for this fungal species' reproductive cycles and mycelial development.
