Water Germander

CR

Teucrium scordium

Pop: Not assessed|Trend:

Water Germander faces severe population declines due to widespread wetland destruction and drainage for agricultural conversion and urban development. The species' specialized habitat requirements make it extremely vulnerable to hydrological changes, water pollution from agricultural runoff, and habitat fragmentation that isolates remaining populations.

Water Lobelia

CR

Lobelia dortmanna

Pop: Not assessed|Trend:

Water Lobelia faces severe threats from habitat degradation due to eutrophication and acidification of its specialized aquatic environments. The species' extremely narrow ecological requirements make it highly vulnerable to water quality changes, while climate change and human activities continue to degrade the pristine lake conditions it depends upon for survival.

VU

Lythrum portula

Pop: Not assessed|Trend:

Water spangles

CR

Salvinia minima

Pop: Not assessed|Trend:

Water spangles faces severe threats from habitat degradation, water pollution, and competition from invasive aquatic species that can rapidly colonize and dominate freshwater ecosystems. Climate change and altered hydrological patterns further threaten the delicate balance of shallow water environments this species depends on. Conservation status may vary by region or assessment authority, but populations continue to decline due to human impacts on freshwater systems.

Water Speedwell

VU

Veronica anagallis-aquatica

Pop: Not assessed|Trend:

Water Speedwell faces significant decline due to habitat loss from wetland drainage, agricultural intensification, and water pollution. Urban development and changes in water management practices have severely reduced suitable aquatic and semi-aquatic habitats across its range.

Water Spider

VU

Argyroneta aquatica

Pop: Not assessed|Trend:

Water Sundew

CR

Drosera intermedia

Pop: Not assessed|Trend:

Water Sundew faces severe threats from habitat destruction due to wetland drainage, peat bog extraction, and agricultural conversion of its specialized carnivorous plant habitats. Climate change and altered hydrology further threaten the precise water level conditions this species requires, while pollution from agricultural runoff and development degrades the nutrient-poor environments essential for its survival.

Water-gladiolus

CR

Butomus umbellatus

Pop: Not assessed|Trend:

Water-gladiolus faces severe threats from habitat destruction due to wetland drainage, water pollution, and agricultural conversion of its native freshwater environments. Climate change and altered hydrological regimes further threaten remaining populations, while invasive species competition reduces available habitat niches.

water-meadow grasshopper

VU

Chorthippus montanus

Pop: Not assessed|Trend:

Water-soldier

CR

Stratiotes aloides

Pop: Not assessed|Trend:

Water-soldier faces severe population declines across its range due to habitat destruction and degradation of freshwater ecosystems. Eutrophication from agricultural runoff and urban pollution has dramatically altered water chemistry in many of its native habitats, while drainage of wetlands for development has eliminated critical breeding and feeding areas.

Waterawlwort

CR

Subularia aquatica

Pop: Not assessed|Trend:

Waterawlwort faces severe threats from habitat degradation and loss of its specialized aquatic environments. Climate change and human activities are reducing the availability of suitable shallow water habitats, while water pollution and eutrophication degrade remaining populations.

Wattled Guan

VU

Aburria aburri

Pop: Not assessed|Trend:

Wavy Waternymph

CR

Najas flexilis

Pop: Not assessed|Trend:

Wavy Waternymph faces severe threats from habitat degradation due to water pollution, eutrophication, and sedimentation that degrade the clear, nutrient-poor waters it requires. Urban development, agricultural runoff, and invasive species competition have led to dramatic population declines across much of its range. The species' sensitivity to water quality changes makes it particularly vulnerable to ongoing environmental pressures.

Wedge Flapwort

CR

Leptoscyphus cuneifolius

Pop: Not assessed|Trend:

Wedge Flapwort faces severe threats from habitat destruction due to deforestation, agricultural expansion, and urban development across its limited range. The species' specialized habitat requirements and small population size make it extremely vulnerable to environmental changes and human disturbance. Climate change poses additional risks by altering the moisture and temperature conditions essential for this bryophyte's survival.

Weeping Toothcrust

VU

Dacryobolus sudans

Pop: Not assessed|Trend:

Based on the available information, the primary threats to Weeping Toothcrust have not yet been formally assessed or documented by scientists. This means researchers have not systematically studied what dangers this fungus species might be facing in the wild. Without a proper threat assessment, it's unclear whether the risks to this species are getting worse, staying the same, or improving over time.

Weinland's Marsupial Frog

CR

Gastrotheca weinlandii

Pop: Not assessed|Trend:

Weinland's Marsupial Frog faces severe threats from habitat destruction due to deforestation, agricultural expansion, and urban development throughout its limited range in the Caribbean.
