Climate change is also emerging as a significant threat, altering the distribution and phenology of both the butterfly and its host plants.

Gro’s Manticores
ENMorunasaurus groi
Gro's Manticores face severe population declines primarily due to habitat destruction from agricultural expansion and urban development in their limited range. Mining activities and infrastructure development have further fragmented their already restricted habitat, while climate change threatens to alter the specific environmental conditions they require.

groene didea
CRDidea alneti
Didea alneti faces severe population decline primarily due to habitat loss from deforestation and agricultural expansion in its limited range. Climate change is altering the species' specialized ecosystem requirements, while invasive species compete for resources and disrupt native food webs.
groene spoorspin
ENCheiracanthium virescens
The groene spoorspin (Cheiracanthium virescens) is declining primarily due to habitat loss and fragmentation from agricultural intensification and urban development. Climate change and pesticide use in agricultural areas further threaten remaining populations of this specialized spider species.
grootbladig puntmos
VUCalliergon megalophyllum

grootoog-bollenzweefvlieg
VUEumerus ornatus
Großer Rettich-Dickfuß
VUCortinarius diosmus

Großer Scheibenbovist
ENDisciseda bovista
Großer Scheibenbovist (Disciseda bovista) is declining primarily due to habitat loss and degradation of its specialized dry grassland environments. Agricultural intensification, urban development, and changes in land management practices have significantly reduced the availability of suitable sandy, nutrient-poor soils where this fungus can establish and reproduce.

Großsporige Morcheltrüffel
VUGautieria morchelliformis

grote gevlekte langlijf
CRSphaerophoria interrupta
Sphaerophoria interrupta, a hoverfly species, faces severe population declines primarily due to habitat loss and degradation of its specialized wetland and grassland environments. Agricultural intensification and urbanization have eliminated much of the species' required breeding and foraging habitat, while climate change may be altering the availability of suitable microhabitats.
grote heidehangmatspin
CRLinyphia tenuipalpis
The grote heidehangmatspin (Linyphia tenuipalpis) is critically endangered primarily due to severe habitat loss and fragmentation of its specialized heathland ecosystem. Agricultural intensification, urban development, and changes in traditional land management practices have dramatically reduced the availability of suitable heathland habitats. Climate change may further threaten the species by altering the microhabitat conditions required for its survival.

grote nachtwolfspin
VUTrochosa robusta
grote piraat
ENPirata piscatorius
Pirata piscatorius faces severe population declines primarily due to habitat loss from wetland drainage and agricultural conversion of its specialized aquatic environments. Water pollution and hydrological changes from human activities further degrade the quality of remaining suitable habitats.
grote spinneneter
VUEro tuberculata
Grote tandklauw
CRCalathus ambiguus
Calathus ambiguus, known as Grote tandklauw, is critically endangered primarily due to habitat loss and degradation of its specialized coastal dune and sandy grassland environments. The species faces severe population decline from urban development, agricultural intensification, and changes in land management practices that have eliminated or fragmented its remaining habitat patches.
grotthuvudspindel
VUWalckenaeria incisa

Ground Beetle
CRCalosoma sycophanta
Calosoma sycophanta, the forest caterpillar hunter, faces severe population declines primarily due to habitat loss from deforestation and forest fragmentation. The species is also threatened by pesticide use in agricultural and forestry practices, which reduces both the beetle populations directly and their prey species. Climate change and altered forest management practices further compound these pressures on remaining populations.
Ground Robber Frog
