Common heathgrass

The common heathgrass, <em>Danthonia decumbens</em>, is a grass species belonging to the family Poaceae. It is typically found in grasslands, wetlands, and forested habitats, with a distribution that includes Europe, North America, Oceania, and South America. <em>Danthonia decumbens</em> is a perennial grass characteristically associated with nutrient-poor, acidic soils, and is a frequent component of heathland, moorland, and dry grassland communities across its range. It is assessed as Near Threatened on the IUCN Red List, suggesting that degradation and loss of its specialized low-nutrient habitats may be contributing to population declines. The species typically forms small tufts and produces cleistogamous flowers that self-fertilize without opening, as well as normal open flowers. No dietary information has been provided for this species. Biological traits of this species remain poorly documented in the scientific literature.
