Northern Shrike

CR

Lanius excubitor

Pop: Not assessed|Trend:

The Northern Shrike faces severe population declines across much of its range due to habitat loss from agricultural intensification and urbanization, which eliminates the open woodlands and shrublands it requires for hunting. Climate change is altering prey availability and breeding conditions, while pesticide use reduces insect populations that form a crucial part of its diet, particularly during the breeding season when feeding young.

Pseudoinonotus dryadeus

Pop: Not assessed|Trend:

Oak Click Beetle

CR

Lacon querceus

Pop: Not assessed|Trend:

The Oak Click Beetle faces severe population declines primarily due to the loss and fragmentation of ancient oak woodlands across its range. Intensive forest management practices, urbanization, and climate change have dramatically reduced the availability of suitable dead wood habitats essential for larval development. Conservation status may vary by region or assessment authority, but the species remains highly vulnerable to continued habitat degradation.

Oak Toothcrust

VU

Radulomyces molaris

Pop: Not assessed|Trend:

Oak Woodwax

CR

Hygrophorus nemoreus

Pop: Not assessed|Trend:

Oak Woodwax faces severe population declines due to widespread destruction and fragmentation of its specialized old-growth forest habitats. Climate change is altering the delicate moisture and temperature conditions this mycorrhizal species requires, while pollution and habitat degradation further compromise the health of its host oak trees and forest ecosystems.

Calocybe obscurissima

Pop: Not assessed|Trend:

Obscure graafwants

CR

Ochetostethus opacus

Pop: Not assessed|Trend:

Ochetostethus opacus faces severe population declines due to widespread habitat destruction from agricultural expansion and urban development across its range. The species' specialized habitat requirements and limited dispersal ability make it particularly vulnerable to fragmentation of remaining suitable areas.

Ochre-Bellied Crayfish

CR

Euastacus mirangudijn

Pop: Not assessed|Trend:

The Ochre-Bellied Crayfish faces severe threats from habitat degradation and water quality decline across its limited range in southeastern Australia. Agricultural runoff, urban development, and altered water flows have significantly impacted the pristine freshwater systems this species requires for survival.

öländsk svavellav

CR

Calogaya schistidii

Pop: Not assessed|Trend:

Öländsk svavellav faces severe threats from habitat degradation and loss of suitable limestone substrates on Öland island. The species' extremely restricted range and specialized ecological requirements make it highly vulnerable to environmental changes and human disturbances in its coastal limestone habitats.

Oldgrowth Rag Lichen

VU

Platismatia norvegica

Pop: Not assessed|Trend:

Oldrose Bolete

CR

Imperator rhodopurpureus

Pop: Not assessed|Trend:

The Oldrose Bolete faces severe threats from widespread deforestation and habitat fragmentation across its range, particularly affecting the mature forest ecosystems it depends on for survival. Climate change is altering precipitation patterns and temperature regimes critical for this mycorrhizal species, while pollution and soil contamination from agricultural and industrial activities are degrading the forest floor environments where it occurs.
