Habitat & Geographic Range

Common Gromwell

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Range

Widely distributed across Asia (Japan), Europe (7 countries), North America (Canada, United States), Oceania and the Pacific (Australia), and South America (Colombia). Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

Comoro Flying Fox

Habitat

Typically found in diverse terrestrial and aquatic ecosystems.

Common Gromwell

<em>Lithospermum officinale</em>, commonly known as common gromwell, is a herbaceous perennial plant belonging to the genus Lithospermum within the family Boraginaceae. This species occupies diverse terrestrial habitats from tropical forests to temperate regions and has a broad intercontinental range, including Japan in Asia, seven European countries, Canada and the United States in North America, Australia in Oceania, and Colombia in South America. Notably, <em>Lithospermum officinale</em> is assessed as Near Threatened on the IUCN Red List, indicating that while it does not currently meet the criteria for a threatened category, it is close to qualifying or is likely to qualify in the near future without ongoing conservation attention. The species typically favors dry, calcareous grasslands and open scrubland. Biological traits of this species remain poorly documented in the scientific literature.

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.
