Scorpion Mud Turtle
VUKinosternon scorpioides
Scotch Argus
CRErebia aethiops
The Scotch Argus faces severe population declines due to habitat fragmentation and loss of its specialized grassland environments. Climate change poses additional pressure by altering the temperature and moisture conditions required for its host plants and larval development. Conservation status may vary by region or assessment authority, but localized extinctions have been documented across portions of its range.

Scottish-briar
VURosa spinosissima

Sea Holly
VUEryngium maritimum

Sea Purslane
CRHalimione portulacoides
Sea Purslane faces severe threats from coastal development, sea level rise, and habitat degradation of its specialized salt marsh environments. The species is particularly vulnerable to climate change impacts that alter salinity levels and flood patterns in its narrow coastal habitat range, while urban expansion and infrastructure development continue to fragment and destroy remaining populations.
Sea Rush
ENJuncus maritimus

Sea Storm Lichen
VUCetrelia olivetorum
The specific threats to Sea Storm Lichen have not yet been assessed by scientists, so the main dangers this species faces are currently unknown. Without this threat assessment, researchers cannot determine what factors might be causing population declines or putting the species at risk. It is unclear whether threats to this lichen are increasing, stable, or decreasing since no formal evaluation has been conducted.
Sea Wormwood
CRArtemisia maritima
Sea Wormwood faces severe threats from coastal development, sea level rise, and habitat destruction of its specialized salt marsh environments. The species' narrow ecological requirements and fragmented populations make it particularly vulnerable to climate change impacts and human encroachment on coastal areas.

Sea-aster Groundling
ENScrobipalpa salicorniae
Sea-wormwood Weevil
VUPolydrusus pulchellus

Seaside Dock
ENRumex maritimus
Seaside Dock is declining primarily due to habitat loss from coastal development, agricultural conversion, and sea-level rise affecting its specialized saltmarsh and mudflat habitats. The species is also threatened by changes in water management and increased disturbance from human activities in coastal areas.

Seathorn Groundling, Seathorn Spinner
ENGelechia hippophaella

Sedge Darner
VUAeshna juncea

Sedge Warbler
ENAcrocephalus schoenobaenus
Seibon
CRPachira emarginata
Pachira emarginata faces severe population declines due to extensive deforestation and habitat conversion throughout its native range in Central and South America. The species is particularly vulnerable to agricultural expansion, urban development, and logging activities that fragment and destroy the wetland and riparian forests it depends on for survival.
seledderkopp
VUMetopobactrus prominulus
Sematophyllum Moss
VUSematophyllum demissum

Semi-aquatic bugs
VUHebrus pusillus
Semifree Morel
VUMorchella semilibera

Semiplumbeous Hawk
VULeucopternis semiplumbeus
sen piprörsgräsmal
VUElachista elegans
Señorita
VUAgeneiosus pardalis
Sepia Pinkgill
VUEntoloma jubatum
Serashi
CRTrichilia trifolia
Serashi faces severe population declines primarily due to widespread deforestation and habitat fragmentation across its native range in tropical America. Agricultural expansion, urban development, and logging activities have significantly reduced available habitat, while remaining populations are increasingly isolated and vulnerable to local extinctions.

Serotine Bat
VUEptesicus serotinus
The Serotine Bat faces significant population declines primarily due to habitat loss from agricultural intensification and urban development, which reduces both roosting sites and insect prey availability. Additional pressures include building renovations that destroy roost sites, pesticide use that depletes food sources, and climate change affecting insect populations and hibernation patterns.
serpent coral
VUPachyseris rugosa
Serpentine Four-toed Galliwasp
ENCelestus agasepsoides
serpentinkalklav
VUEndocarpon psorodeum

Sessile Earthstar
VUGeastrum fimbriatum
Sessile-leaved Rhodothamnus
CRRhodothamnus sessillifolius
Sessile-leaved Rhodothamnus faces severe threats from habitat loss and fragmentation due to tourism development, infrastructure expansion, and climate change in its restricted alpine range. The species' extremely limited distribution in the Eastern Alps makes it particularly vulnerable to localized disturbances and environmental changes. Conservation status may vary by region or assessment authority.
sexmaskros
CRTaraxacum obtusilobum
Taraxacum obtusilobum faces severe threats from habitat loss due to agricultural expansion and urban development in its specialized alpine and subalpine environments. Climate change poses an additional critical threat as warming temperatures force this cold-adapted species to retreat to increasingly limited high-elevation refugia. The species' restricted range and small population size make it particularly vulnerable to local extinctions from human disturbance and environmental changes.
Seychelles Fineliner
VUTeinobasis alluaudi

Seychelles House Snake
ENLamprophis geometricus
Shade Bramble
VURubus nemorosus

Shaggy Bracket
VUInonotus hispidus
Sharp Rock-bristle
VUSeligeria acutifolia

Sharp-flowered Rush
CRJuncus acutiflorus
Sharp-flowered Rush faces severe threats from wetland habitat destruction and degradation due to agricultural intensification, drainage projects, and urban development. Climate change-induced alterations to hydrological regimes and increased frequency of extreme weather events further compromise the specialized acidic wetland conditions this species requires for survival.

Sharp-leaved Fluellen
ENKickxia elatine

Sharp-scaly Pholiota
VUPholiota squarrosoides

Sharp-tailed Tyrant / Sharp-tailed Grass-Tyrant
VUCulicivora caudacuta

Sharpbill
VUOxyruncus cristatus
Sharpsnout Torrent Frog
CRTaudactylus acutirostris
The Sharpsnout Torrent Frog faces severe threats from chytrid fungus disease, which has caused widespread amphibian declines across Australia's wet tropics. Additional pressures include habitat degradation from land clearing, water pollution, and climate change impacts on its specialized stream environments.
Shasta Salamander
VUHydromantes shastae
Sheep's Bit Dufourea
VUDufourea halictula

Sheep's-bit Conch
VUClepsis pallidana

Shepherd's Needle
ENScandix pecten-veneris

Shetland Pondweed
CRPotamogeton rutilus
Shetland Pondweed faces severe threats from habitat degradation and loss due to water pollution, eutrophication, and human disturbance of its aquatic environments. The species' extremely limited distribution makes it particularly vulnerable to localized threats, while climate change and altered water chemistry further compromise its survival prospects.

Shillong Bush Frog
CRRaorchestes shillongensis
The Shillong Bush Frog faces severe threats from rapid habitat destruction due to urbanization and agricultural expansion in the Khasi Hills region of Meghalaya, India. Its extremely limited range and specialized habitat requirements make it particularly vulnerable to environmental changes and human encroachment. The species' small population size and fragmented distribution further increase its extinction risk.
Shiner Milkcap
CRLactarius uvidus
The Shiner Milkcap faces severe threats from habitat loss due to deforestation and forest fragmentation, which destroys the specific mycorrhizal relationships essential for its survival. Climate change is altering forest conditions and disrupting the delicate ecological balance required for this fungus to fruit and reproduce. Conservation status may vary by region or assessment authority, but declining populations reflect the vulnerability of specialized forest fungi to environmental changes.
Shingle Moss
VUNeckera pennata
Shingle Moss (Neckera pennata) is declining primarily due to habitat loss and degradation from deforestation, air pollution, and climate change affecting the specific microclimate conditions it requires. The species is particularly vulnerable because it depends on old-growth forests with stable humidity and temperature conditions that are increasingly rare.
