Habitat & Geographic Range

clustered earth moss

Habitat

Native to Europe and North America, inhabiting ecosystems characteristic of the region.

Range

Distributed across Norway, Portugal, and United States.

Coastal wattle

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 8 distinct biome types spanning the Afrotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

clustered earth moss

Ephemerum cohaerens is a tiny, ephemeral moss in the family Pottiaceae (or Ephemeraceae, according to some classification schemes) with a distribution across Europe and North America. The genus Ephemerum consists of minute mosses that lack a persistent leafy gametophyte stage visible to the naked eye; instead, the dominant visible structure is the sporophyte, with the diminutive gametophytes bearing single stalked capsules close to the soil surface. E. cohaerens grows on moist, disturbed, bare soil in arable fields, garden beds, paths, and river margins. These ephemeral mosses are early colonizers of open mineral soils, completing their life cycle rapidly and then disappearing. They rely on conditions with minimal competition from taller vegetation. The species has not been formally evaluated by the IUCN for conservation status, reflecting the limited demographic data available for many bryophyte species. Ephemeral mosses of arable habitats are of some conservation interest in Europe, where intensification of agriculture has reduced the extent and frequency of winter-fallow bare soil conditions that these species require.

Coastal wattle

Coastal wattle (Acacia cyclops) is a dense, fast-growing shrub in the family Fabaceae, native to the southwestern and southern coastal regions of Western Australia, from Shark Bay south to the Nullarbor Plain. It grows on coastal dunes, sandy scrubland, and limestone substrates near the sea, where it tolerates salt spray, wind, and summer drought. Coastal wattle produces distinctive circular seeds with bright red arillate coatings, making them highly attractive to birds. Although valued in its native range for coastal stabilisation and revegetation, the species has become highly invasive in southern Africa, particularly South Africa, where it was introduced for dune stabilisation in the 19th century and has since spread extensively across the Cape Floristic Region, displacing native fynbos vegetation. It is listed among the 100 worst invasive species globally by the IUCN Invasive Species Specialist Group. In Australia, it is assessed as Least Concern. Management of invasive populations in South Africa involves mechanical removal and biological control efforts aimed at protecting the critically threatened fynbos biome.
