Habitat & Geographic Range

Cliff Mining Bee

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Denmark, Luxembourg, Norway, and Sweden.

bous

Habitat

Found across multiple habitat types including flooded grasslands and savannas, deserts and xeric shrublands, and temperate broadleaf and mixed forests, among 6 distinct biome types spanning the Afrotropic and Palearctic and Indomalayan realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (4 countries), Asia (Iran, Pakistan, Taiwan), Europe (7 countries), North America (Canada, United States), Oceania and the Pacific (Australia, New Zealand), and South America (4 countries).

Cliff Mining Bee

The Cliff Mining Bee, Andrena species in the family Andrenidae, is a solitary ground-nesting bee that excavates tunnels in cliff faces, earthen banks, and compacted sandy or loamy soils, where the loose or friable substrates exposed in cliff profiles provide ideal nesting conditions. Mining bees in the genus Andrena are among the most species-rich solitary bee genera in the world, with hundreds of species across the Holarctic region, many narrowly specialized in their choice of pollen host plants. Female cliff mining bees construct vertical or angled burrows in cliff faces, with lateral cells off the main shaft, each containing a pollen ball and a single egg. Males are typically smaller and emerge before females to establish territories near nesting sites. Many Andrena species are oligolectic, collecting pollen from only a small number of plant species, making their populations sensitive to the availability of specific flowering plants in the landscape surrounding nesting areas. Cliff and bank nesting habitats provide well-drained, sun-warmed substrates essential for brood development. The loss of natural cliff faces and earthen banks to development, vegetation succession, and quarrying reduces available nesting habitat for cliff mining bees.

bous

<em>Phragmites australis</em>, the common reed, is one of the most widely distributed vascular plants on Earth, placed in the family Poaceae, order Poales. Its range encompasses all inhabited continents, including Africa, Asia, Europe, North America, Oceania, and South America, typically colonizing freshwater margins, brackish marshes, lake shores, riverbanks, and coastal wetlands. The species is assessed as Least Concern by the IUCN, with globally abundant populations, though some regional variants are subject to conservation concern. Common reed typically forms dense monoculture stands reaching heights of two to six meters, providing critical habitat structure for a wide range of wetland birds, invertebrates, and small mammals. It is a rhizomatous perennial grass, spreading vegetatively through extensive underground root systems as well as by wind-dispersed seeds. As an autotroph, <em>Phragmites australis</em> obtains energy through photosynthesis and plays a major role in nutrient cycling and carbon sequestration within wetland ecosystems. The species has significant economic value in thatching, basketry, and constructed wetland wastewater treatment systems. In North America, an introduced European genotype has become invasive, displacing native plant communities. Biological traits vary considerably across its global range.
