Habitat & Geographic Range

Common carpetgrass

Habitat

Typically found in grasslands, wetlands, forests, and cultivated landscapes.

Range

Widely distributed across Africa (9 countries), Asia (7 countries), Europe (5 countries), North America (4 countries), Oceania and the Pacific (8 countries), and South America (Brazil, Colombia).

Laysan Duck

Habitat

Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and Mediterranean forests and woodlands within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Belgium, France, Netherlands, Norway, and United Kingdom. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Common carpetgrass

<em>Axonopus fissifolius</em>, commonly known as common carpetgrass, is a grass species with a broad global distribution spanning Africa, Asia, Europe, the Americas, and Oceania. It typically thrives in grasslands, wetlands, forests, and cultivated areas, often tolerating poorly drained and low-fertility soils. Common carpetgrass belongs to the genus <em>Axonopus</em> within the family Poaceae. It is a low-growing, stoloniferous grass that typically forms dense mats along roadsides, disturbed areas, lawns, and pastures in warm and humid climates. The species is frequently used as a lawn and pasture grass in tropical and subtropical regions due to its tolerance of mowing and its ability to spread vegetatively. Biological traits such as average lifespan, plant height, and biomass of this species remain poorly documented in the scientific literature. The species has not yet been formally evaluated by the IUCN, and its global conservation status therefore remains undetermined. Its widespread occurrence across multiple continents and highly varied habitats suggests strong ecological adaptability.

Laysan Duck

Laysan Duck (Anas laysanensis) is classified as Critically Endangered (CR) on the IUCN Red List. Facing an extremely high risk of extinction in the wild due to severe population decline and habitat loss.
