The species' specialized habitat requirements and small population size make it particularly vulnerable to environmental changes and human disturbance.

Hypsosinga sanguinea

Habitat loss due to heathland conversion for agriculture and urban development poses the primary threat to heidepyamaspin populations. Climate change and the encroachment of invasive plant species are further degrading the specialized microhabitats this spider requires for web construction and prey capture.

Gnaphosa leporina

Gnaphosa leporina faces severe population declines primarily due to habitat loss from agricultural intensification and urban development in its limited range. The species' specialized habitat requirements and small population size make it particularly vulnerable to environmental changes and human disturbance.

Myrmica sulcinodis

Myrmica sulcinodis faces severe population declines primarily due to habitat loss and degradation of its specialized heathland and moorland ecosystems. Climate change and agricultural intensification have further reduced the availability of suitable nesting sites and altered the microclimatic conditions this species requires.

Hennediella heimii

Limnonectes heinrichi

Dermoloma josserandii

Crossocalyx hellerianus

Hygrophorus lindtneri

Hygrophorus lindtneri faces severe population declines primarily due to habitat loss from deforestation and agricultural conversion of its specialized forest ecosystems. Climate change is altering the moisture and temperature conditions essential for this mycorrhizal fungus, while pollution and soil contamination further degrade its habitat quality.

Marpissa nivoyi

Marpissa nivoyi faces severe population declines primarily due to habitat destruction from urban development and agricultural expansion in its limited range. The species' specialized habitat requirements and small population size make it particularly vulnerable to environmental changes and human disturbance.

Clubiona frisia

Helvella solitaria

Aethes beatricella

Adaina microdactyla

Hemp Agrimony Plume (Adaina microdactyla) faces significant decline primarily due to habitat loss and degradation of wetland areas where its host plant Hemp Agrimony grows. Agricultural intensification, drainage of marshy areas, and urban development have reduced suitable breeding habitats across its European range.

Grifola frondosa

Hyoscyamus niger

Henbane (Hyoscyamus niger) faces significant population declines primarily due to habitat loss from agricultural intensification and urban development. The species is particularly vulnerable because it depends on disturbed soils and waste ground that are increasingly being converted to intensive agriculture or built development.

Heppia lutosa

Heppia lutosa, a crustose lichen species, faces significant threats from habitat degradation and loss due to air pollution, particularly nitrogen deposition and sulfur compounds that alter the chemical composition of its substrate. Climate change and urbanization further threaten the specialized microhabitats this species requires for survival.

Cottus rondeleti

The Hérault sculpin is critically endangered due to its extremely limited range, being endemic to a small section of the Hérault River basin in southern France. The species faces severe threats from habitat degradation, water pollution, and hydrological modifications that have drastically reduced suitable spawning and nursery areas. Climate change and drought conditions further exacerbate these pressures by reducing water flow and increasing water temperatures beyond the species' tolerance levels.

Oligotrichum hercynicum

Osmoderma eremita

The Hermit beetle is critically endangered primarily due to the loss and fragmentation of old-growth deciduous forests containing ancient hollow trees, which are essential for its larval development. Modern forestry practices that remove dead and dying trees, along with urbanization and agricultural expansion, have severely reduced suitable habitat across Europe. The species' extremely slow development cycle and limited dispersal ability make populations particularly vulnerable to habitat disturbance.

Larus argentatus

Miscophus spurius

Miscophus spurius faces severe population declines due to habitat destruction from agricultural expansion and urbanization across its limited range. The species' specialized parasitoid lifestyle makes it particularly vulnerable to pesticide use and the decline of its specific host species, creating cascading effects that threaten remaining populations.

Fabriciana adippe

The High Brown Fritillary has experienced severe population declines across its range due to habitat loss and degradation, particularly the loss of traditional woodland management practices that maintained the warm, sheltered clearings this species requires. Climate change and habitat fragmentation have further reduced suitable breeding sites, while the abandonment of coppicing and other woodland management has led to increased canopy closure that eliminates the sun-dappled conditions needed by both the butterfly and its violet host plants.
