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.

Comoro Flying Fox

<em>Pteropus livingstonii</em>, the Comoro flying fox or Livingstone's fruit bat, is a large fruit bat in the family Pteropodidae, endemic to the Comoro Islands in the western Indian Ocean, where it is restricted to Anjouan and Mohéli. It is one of the largest bats in the world, with a wingspan that can exceed one meter and a body weight reportedly ranging between 400–700 g. The species roosts colonially in tall native forest trees, particularly in humid upland forest fragments, and feeds on a variety of native fruits, nectar, and pollen, playing a critical role as a seed disperser and pollinator in Comoran forest ecosystems. Precise average lifespan data in the wild remain poorly documented, though captive individuals have lived over 20 years. <em>Pteropus livingstonii</em> is assessed as Critically Endangered by the IUCN, making it one of the most threatened bat species in the world. Primary threats include extensive deforestation driven by agricultural expansion and charcoal production, which has severely reduced suitable roosting and foraging habitat, along with historic hunting. Conservation efforts include habitat protection, community education programs, and captive breeding initiatives at several European zoos coordinated through an international species survival program.
