Habitat & Geographic Range

Alder leaf beetle

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, Norway, Sweden, and United States.

Common Juniper

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, temperate grasslands and steppes, and flooded grasslands and savannas, among 6 distinct biome types spanning the Neotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Libya), Europe (6 countries), North America (United States), Oceania and the Pacific (Australia), and South America (Argentina, Brazil). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Alder leaf beetle

The Alder leaf beetle (Agelastica alni) is a species in the genus Agelastica. It is currently classified as Least Concern on the IUCN Red List. Typically found in virtually all terrestrial and freshwater habitats.

Common Juniper

Common Juniper (<em>Juniperus communis</em>) is a coniferous shrub or small tree in the family Cupressaceae and one of the most widely distributed woody plants in the Northern Hemisphere. It is classified as Vulnerable on the IUCN Red List, indicating population declines driven by habitat loss, overgrazing, and changes in land management. The species has a remarkably broad native range spanning Africa (Libya), Europe (six countries), North America (United States), Oceania (Australia), and South America (Argentina and Brazil). It typically inhabits six distinct biome types and occurs within both the Neotropic and Palearctic biogeographic realms. Common Juniper grows in heathlands, rocky slopes, calcareous grasslands, open woodlands, and alpine environments, often colonizing nutrient-poor soils where competition from other plants is limited. Its berries are widely used as a flavoring for gin and in traditional cuisine. Biological traits of this species remain poorly documented in the scientific literature.
