Helvella spadicea

Pop: Not assessed|Trend:

noords kaardertje

CR

Dictyna major

Pop: Not assessed|Trend:

Dictyna major faces severe population declines due to habitat destruction from urbanization and agricultural expansion, which eliminates the specific microhabitats this specialized spider requires. Climate change and pollution further threaten remaining populations by altering the delicate ecological conditions necessary for web construction and prey availability.

CR

Chrysis zetterstedti

Pop: Not assessed|Trend:

Chrysis zetterstedti faces severe population declines due to habitat loss from agricultural intensification and urban development in its limited range. The species' specialized parasitic lifestyle makes it particularly vulnerable to disruptions in host species populations and the degradation of sandy, open habitats essential for both the wasp and its hosts.

Norfolk Damselfly

EN

Coenagrion armatum

Pop: Not assessed|Trend:

The Norfolk Damselfly is critically threatened by habitat loss and degradation of its specialized wetland environments on Norfolk Island. The species' extremely limited range makes it highly vulnerable to environmental changes, invasive species, and human disturbance of its freshwater breeding sites.

Norfolk Hawker

CR

Aeshna isoceles

Pop: Not assessed|Trend:

The Norfolk Hawker faces severe threats from habitat loss and degradation of its specialized wetland environments, particularly through drainage of grazing marshes and water level management changes. Climate change poses additional risks through altered precipitation patterns and increased frequency of extreme weather events that can disrupt breeding cycles and larval development in shallow water bodies.

Norfolk Skullcap

CR

Scutellaria hastifolia

Pop: Not assessed|Trend:

Norfolk Skullcap faces severe threats from its extremely limited distribution on Norfolk Island, where habitat degradation from invasive plant species and historical land clearing have significantly reduced suitable growing areas. The species' small population size makes it highly vulnerable to stochastic events and genetic bottlenecks, while ongoing pressure from introduced weeds continues to degrade its remaining habitat.

Northern Damselfly

CR

Coenagrion hastulatum

Pop: Not assessed|Trend:

The Northern Damselfly faces severe threats from climate change, which is causing the warming and acidification of its specialized bog and moorland habitats. Habitat destruction through peat extraction, drainage of wetlands, and agricultural conversion has significantly reduced available breeding sites, while pollution from agricultural runoff and atmospheric deposition further degrades water quality in remaining habitats.

Northern Emerald

CR

Somatochlora arctica

Pop: Not assessed|Trend:

The Northern Emerald faces severe threats from climate change, which is altering the cold, pristine bog and fen habitats essential for its survival.
