Brook Alder

The Brook Alder (Alnus maritima) is a species in the genus Alnus. It is currently classified as Endangered on the IUCN Red List. Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Common Ivy

<em>Hedera helix</em>, commonly known as common ivy or English ivy, is a woody evergreen climber and groundcover in the family Araliaceae. It is classified as Least Concern on the IUCN Red List, with a very wide global distribution across the Palearctic realm and beyond, encompassing temperate and Mediterranean habitats. The species is native to Europe and western Asia and has been widely introduced elsewhere. It typically grows in woodlands, hedgerows, cliffs, walls, and urban green spaces, tolerating deep shade and a wide range of soil conditions. Common ivy provides important ecological services, offering shelter and late-season nectar and fruit resources for wildlife. Diet information for this species is not available in current records. Biological traits of this species remain poorly documented in the scientific literature.
