Common Carder Bee

<em>Bombus pascuorum</em>, commonly known as the common carder bee, is a bumblebee species found across Europe, with documented occurrences in Belgium, Denmark, Norway, Portugal, Sweden, and additional European countries. It typically inhabits all terrestrial and freshwater environments, often foraging across a wide range of flowering plants in meadows, gardens, hedgerows, and farmland. The species is classified as Least Concern on the IUCN Red List, indicating a broadly stable global population. Common carder bee belongs to the genus <em>Bombus</em> within the family Apidae and is one of the more widely distributed bumblebee species in Europe. It often nests above ground in dry grass, moss, or other plant material, building compact nests characteristic of carder bees. As a generalist pollinator, it visits a diverse range of flowering species and contributes meaningfully to ecosystem pollination services. Biological traits such as average lifespan, body length, and mass of this species remain poorly documented in the scientific literature.

Eurasian beaver

Eurasian beaver (Castor fiber) is classified as Vulnerable (VU) on the IUCN Red List. Facing a high risk of endangerment in the wild, with declining populations and increasing habitat pressure.
