Biodiversity Loss - Artensterben

Mehr Pflanzenarten sind nicht automatisch gut

More greenery does not necessarily mean more intact nature: many of Europe’s plant communities are shifting in favor of robust generalists. Image: Doreen Fräßdorf

Biodiversity: When more plant species are not a good sign

At first glance, it sounds like good news: in many European habitats, there are now locally more plant species than in the past. An international study led by Martin Luther University Halle-Wittenberg analyzed 57,390 vegetation time series from across Europe. In total, 199,282 individual vegetation surveys were included; some time

Nature on the doorstep: Why we hardly know many species anymore

Dandelions, daisies, stinging nettles or sparrows—many people can still name these species. But what about the plants and birds that are typical of meadows, pastures, field edges and arable fields? A new study by the Leibniz Centre for Agricultural Landscape Research (ZALF) on species knowledge shows that many characteristic species

Rotbindiger Samtfalter (Arethusana arethusa)

The false grayling (Arethusana arethusa) occurs in dry, warm open habitats in southern and south-eastern Europe. According to the respective Red Lists, it is now regionally extinct in Germany and Switzerland; the last records date from 1977 and 1974 respectively.

Europe’s butterflies: What Red Lists reveal about their decline

Many people are now reporting something similar: where numerous butterflies still flew over meadows, gardens, roadside verges or embankments in summer a few years ago, today there are often only a few—or none at all—to be seen. Such observations are initially personal and local; they depend on the weather, the

The dwarf bulrush (Typha minima) represents a habitat that has been heavily altered in Germany: dynamic river floodplains with open sandy, silty, and gravelly banks. Both subspecies listed in the Red List are considered extinct or no longer found in Germany. Image: Typha minima Funck Observed in France by Flavien Saboureau, CC BY 4.0, via GBIF

Extinct or lost: Plants that no longer occur in Germany

The current nationwide Red List of Germany’s ferns and flowering plants, published in 2018, shows how profoundly the country’s flora has already changed: more than a quarter of the assessed species and subspecies are threatened. In Germany, 65 taxa are even considered extinct or no longer found—equivalent to 1.8% of

Moorfrosch (Rana arvalis) - Moore als Lebensraum

The moor frog (Rana arvalis) is probably one of the most famous moor dwellers. It not only inhabits moors, but also other wet habitats such as swamp forests, wet meadows, swampy grassland and floodplains. Image: Depositphotos (Cooperation)

More than just carbon sinks: Peatlands as habitats for endangered species

Peatlands have long been seen as mysterious, hard-to-reach landscapes. In stories and films, they often appear as dangerous places with unstable ground, dark water and fog—places where someone might sink or disappear without a trace. Ecologically, however, they are far more than this old image: they are among the most

Some plant species have dwindled to fewer than ten mature individuals in the wild.

The world’s loneliest plants: Species with fewer than ten individuals

For some plant species, fewer than ten mature wild plants remain in nature—sometimes even just a single individual. Such species show how far a decline can go: habitats shrink, populations break apart, and in the end only isolated plants remain, their survival often depending on chance. 15 plant species with

Sacramento Mountains Checkerspot Butterfly (Euphydryas anicia cloudcrofti)

Sacramento Mountains checkerspot: the last known individual in human care, a caterpillar, died in May 2026. The subspecies has not been confirmed in the wild since 2022; whether it still occurs there is uncertain.

Sacramento Mountains checkerspot butterfly: last known caterpillar has died

May 5, 2026, ABQ BioPark in Albuquerque, New Mexico: The last known caterpillar of the Sacramento Mountains checkerspot butterfly dies—and with it, perhaps, the chance to save an entire butterfly subspecies from extinction. Researchers had hoped that the caterpillar would still transform into an adult butterfly. Then it might have

Plant Blindness: Zwergkrug (Cephalotus follicularis)

The Albany pitcher plant (Cephalotus follicularis) from Western Australia belongs to an evolutionarily unique plant lineage with no close relatives. This carnivorous plant catches insects with pitcher-shaped pitfall traps—and perhaps for that very reason shows how often people only notice plants when they seem to have "animal-like" traits.

Plant blindness: Why plant extinction often goes unnoticed

Many people barely notice plants consciously. On a theater stage, they would in a sense be the backdrop, while animals would stand in the foreground as the actual actors. Plants often appear only as a “green mass”, not as living beings in their own right, with individual species, complex adaptations

Meeres-Hundertfüßer (Strigamia maritima)

Red List 2026: Germany’s centipedes and millipedes are under pressure

A barely noticed animal world lives beneath our feet. Centipedes and millipedes move through their habitats among leaves, deadwood, roots, stones and crevices in the soil. In the process, they perform important tasks: centipedes hunt small soil animals, while millipedes break down dead plant material and thus contribute to the

Some of the rarest animal species in the world: from the nearly extinct vaquita to the red wolf, the Yangtze giant softshell turtle, the Okinawa spiny rat, and the northern white rhino. These species now survive only in tiny populations.

Fewer than 50 individuals: These animal species have almost disappeared

There are animal species worldwide whose populations have now shrunk to just a few dozen or even only single individuals. Many of them stand on the brink of extinction and survive only in small refuges or through elaborate conservation programs. The main cause of their decline is humans, for example
