Habitat & Geographic Range

Cluster Bat

Habitat

Typically found in diverse terrestrial and aquatic ecosystems.

Range

Found in United States. Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

Common Yew

Habitat

Found across multiple habitat types including temperate broadleaf and mixed forests, tundra, and tropical and subtropical moist broadleaf forests, among 6 distinct biome types spanning the Australasia and Oceanian and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Libya), Europe (10 countries), North America (United States), Oceania and the Pacific (New Zealand), and South America (Brazil). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Cluster Bat

Myotis sodalis, the Indiana bat or cluster bat, is a medium-sized insectivorous bat in the family Vespertilionidae endemic to the eastern United States. It is one of the most endangered bats in North America, listed as Endangered under the U.S. Endangered Species Act and classified as Near Threatened by the IUCN. The species is named for its behavior of clustering in extremely dense hibernation groups—sometimes thousands of bats per square meter—in specific limestone caves and mines during winter. These few critical hibernacula make the species extremely vulnerable to disturbance and disease. Since 2007, Indiana bats have suffered severe mortality from white-nose syndrome, a fungal disease caused by Pseudogymnoascus destructans that disrupts hibernation and causes mass starvation. During summer, Indiana bats roost under loose bark of dead trees and forage for insects over forested landscapes and riparian areas. Foraging individuals consume moths, beetles, and flying insects. Conservation efforts include cave gate protection, white-nose syndrome research, and summer habitat management on public and private lands across the eastern US.

Common Yew

<em>Taxus baccata</em>, the common yew or English yew, is a slow-growing evergreen conifer in the family Taxaceae, native to western, central, and southern Europe, northwest Africa, and southwest Asia. It is one of the longest-lived trees in the Northern Hemisphere, with some individuals estimated to be several thousand years old. The species grows in a variety of habitats including mixed deciduous woodland, calcareous scrub, chalk downlands, and rocky slopes, often as an understorey or emergent tree. Yews are dioecious; female trees produce distinctive bright red fleshy arils surrounding a single hard seed, the only non-toxic part of the plant. All other parts, including the leaves, bark, and seeds, contain highly toxic taxine alkaloids that are dangerous to humans and most animals. Average lifespan can exceed 1,000 years under suitable conditions. <em>Taxus baccata</em> is ecologically important as dense, long-lived woodland habitat and as food for birds that disperse its seeds. Medicinally, taxol derived from yew bark is used in cancer treatment. The species is assessed as Vulnerable due to habitat degradation, overgrazing, and historic overexploitation across parts of its native range, though it remains locally common.
