Taraxacum rubrolineatum

Pop: Not assessed|Trend:

Taraxacum rubrolineatum faces severe threats from habitat loss due to agricultural expansion and urban development in its limited range. Climate change poses additional risks through altered precipitation patterns and temperature shifts that affect its specialized alpine and subalpine habitat requirements.

Scheuchzeria palustris

Pop: Not assessed|Trend:

ranunkelvivel

CR

Bagous czwalinai

Pop: Not assessed|Trend:

Ranunkelvivel faces severe threats from habitat degradation and loss of its specialized wetland environments. The species' dependence on specific aquatic plant hosts makes it particularly vulnerable to water pollution, drainage of wetlands, and changes in water quality that affect its food sources.

Raspabalsa

CR

Sturisomatichthys frenatum

Pop: Not assessed|Trend:

Sturisomatichthys frenatum faces severe threats from habitat degradation due to deforestation, agricultural expansion, and water pollution in its native South American river systems. Dam construction and water diversions have fragmented populations and altered critical flow regimes. The species' limited distribution and specialized habitat requirements make it particularly vulnerable to environmental changes.

Red Balau

CR

Shorea kunstleri

Pop: Not assessed|Trend:

Red Balau faces severe threats from extensive deforestation and habitat conversion throughout its native range in Southeast Asia, particularly due to palm oil plantations, logging operations, and agricultural expansion. The species' slow growth rate and specific habitat requirements make recovery extremely difficult once populations are fragmented or eliminated. Conservation status may vary by region or assessment authority, but the overall trajectory indicates critical population declines.

Red Barbed Ant

VU

Formica rufibarbis

Pop: Not assessed|Trend:

Red Bartsia

CR

Odontites vernus

Pop: Not assessed|Trend:

Red Bartsia faces severe population declines due to widespread habitat loss from agricultural intensification and urban development across its range. The species' dependence on traditional low-intensity farming systems and semi-natural grasslands makes it particularly vulnerable to modern land-use changes and the abandonment of extensive grazing practices.

Red Elm Pigmy

CR

Stigmella lemniscella

Pop: Not assessed|Trend:

The Red Elm Pigmy faces severe population declines due to widespread loss of its elm host trees from Dutch elm disease and habitat fragmentation. Urban development and agricultural expansion have eliminated much of the species' remaining suitable habitat, while climate change threatens the delicate synchronization between the moth's lifecycle and its host plant phenology.

Red-backed Shrike

CR

Lanius collurio

Pop: Not assessed|Trend:

The Red-backed Shrike faces severe population declines across its range due to widespread habitat loss and agricultural intensification that eliminates the thorny scrubland and traditional farming landscapes it depends on. Climate change is altering the timing and availability of insect prey, while pesticide use has dramatically reduced food sources, pushing this species toward critical endangerment.

Red-billed Tyrannulet

VU

Zimmerius cinereicapilla

Pop: Not assessed|Trend:

Red-breasted Copra Beetle

VU

Necrobia ruficollis

Pop: Not assessed|Trend:

Red-breasted Merganser

VU

Mergus serrator

Pop: Not assessed|Trend:

Red-crested Pochard

CR

Netta rufina

Pop: Not assessed|Trend:

This critically endangered species faces severe population declines due to widespread wetland drainage and degradation across its range, particularly affecting crucial breeding and wintering sites. Additional pressures from hunting, pollution, climate change-induced habitat shifts, and human disturbance at remaining wetland refugia continue to push populations toward extinction.

Red-crowned Toadlet

VU

Pseudophryne australis

Pop: Not assessed|Trend:

Red-eyed Damselfly

Erythromma najas

Pop: Not assessed|Trend:

Red-Flanked Bluetail

EN

Tarsiger cyanurus

Pop: Not assessed|Trend:

Red-Footed Tortoise

CR

Chelonoidis carbonarius

Pop: Not assessed|Trend:

The Red-Footed Tortoise faces severe population declines across its range due to intensive hunting for food and the illegal pet trade, combined with widespread habitat destruction from deforestation and agricultural expansion. Large-scale collection of adults for consumption has dramatically reduced breeding populations, while habitat fragmentation isolates remaining groups and prevents natural population recovery.

Reddish Notchwort

CR

Lophozia longiflora

Pop: Not assessed|Trend:

Reddish Notchwort faces severe threats from habitat loss due to development, pollution, and climate change impacts on its specialized bryophyte communities. The species' extremely limited distribution and specific microhabitat requirements make it particularly vulnerable to environmental disturbances and fragmentation of suitable sites.

Reddish Pondweed

CR

Potamogeton alpinus

Pop: Not assessed|Trend:

Reddish Pondweed faces severe threats from habitat degradation and loss due to water pollution, eutrophication, and wetland drainage across its range. Climate change and altered hydrological regimes further threaten the specific water chemistry and temperature conditions this aquatic plant requires for survival.
