Cider Gum

The cider gum (Eucalyptus gunnii) is a medium to large eucalyptus tree native to the highlands of Tasmania, Australia, where it grows at elevations up to 1,400 meters in subalpine and montane environments. It is one of the most cold-hardy eucalypts, tolerating severe frosts and occasional snow, which has made it widely popular in cultivation far beyond its native range, particularly in Britain, Ireland, France, and other temperate parts of Europe. In Tasmania, cider gum typically grows along the margins of highland lakes and in subalpine moorland and wet sclerophyll communities. The species reaches 15–35 meters in height, with smooth, pale gray-green to white bark that peels in ribbons. Young foliage is distinctive round and silver-blue, aging to more elongated sickle-shaped adult leaves. The name cider gum derives from the practice of Tasmanian Aboriginal people fermenting the sweet sap that pools in natural wounds to produce a mildly fermented drink. The species is classified as Not Evaluated by the IUCN. Eucalyptus gunnii provides habitat for several Tasmanian endemic species and is considered an important component of highland vegetation communities. In its introduced European range, it is a popular ornamental and windbreak tree. Concerns exist about its naturalization in some European countries where it has established self-sustaining populations.

Common Pipistrelle

<em>Pipistrellus pipistrellus</em>, the common pipistrelle, is a small bat in the family Vespertilionidae and one of the most abundant and widespread bat species in Europe. It is typically one of the first bats to emerge at dusk, flying with rapid, jerky wingbeats as it pursues small flying insects over gardens, woodland edges, water bodies, and urban areas. The species roosts in crevices in buildings, bat boxes, and tree holes, often forming large maternity colonies in summer. <em>Pipistrellus pipistrellus</em> echolocates at a characteristic frequency of around 45 kHz, which allows it to be identified using bat detectors. It is distributed across Europe, with confirmed records from Belgium, Denmark, Luxembourg, Norway, and Portugal, among many other countries. The species is assessed as Vulnerable on the IUCN Red List, reflecting population declines driven by loss of foraging habitat, reduction in insect prey biomass, disturbance of roost sites, and pesticide use. Biological traits such as average lifespan, body size, weight, and detailed dietary composition across its range remain poorly documented in the scientific literature, though the species is known to consume large numbers of small moths, midges, and other aerial insects each night.
