grassassociated

grassassociated is an adjective used in ecology, botany, and agricultural science to denote relationships, organisms, or processes that are tied to grasses and grass-dominated ecosystems. It describes anything connected with grasses of the Poaceae family or with habitats where grasses are dominant, including wild grasslands, pastures, meadows, and turfgrass systems. The term is often used to categorize species or interactions that occur specifically in association with grasses, rather than in other plant communities.

Grass-associated relationships span a range of interactions. They include mutualists such as endophytic fungi living within grass tissues and arbuscular mycorrhizal fungi in the root zone, which can influence plant health and nutrient uptake. They also include herbivores and pathogens specialized on grasses, such as certain insects, fungi, and rusts, as well as non-pathogenic commensals in the phyllosphere and rhizosphere. Wildlife and domesticated grazers can be described as grass-associated due to their reliance on grassland resources. In turf and forage sciences, the term helps distinguish management considerations that target grasses and their associated biota from those applicable to other crops.

In practice, researchers use the concept to study ecosystem functioning, biodiversity in grasslands, and the health of lawns and pastures. Management practices, including grazing regimes, irrigation, and fungicide or fertilizer choices, are often evaluated for their effects on grass-associated communities.
