grasvelden

Grasvelden are fields in which grasses are the dominant vegetation. They encompass natural grasslands as well as cultivated pastures and hay fields. In natural grasslands, grasses form a continuous herbaceous layer, often interspersed with forbs, and their structure and composition depend on soil type, moisture, land use, and disturbance. Managed grasvelden are kept for agricultural purposes, mainly as forage for grazing livestock or for the production of hay, silage, or seed.

Common forage grasses in temperate regions include perennial ryegrass (Lolium perenne), meadow fescue (Festuca pratensis), cocksfoot (Dactylis glomerata), and timothy (Phleum pratense). These are frequently grown in mixtures with leguminous plants such as red clover (Trifolium pratense) or white clover (Trifolium repens) to improve nutritional value and soil nitrogen.

Production and management practices vary. Grazing systems may be continuous or rotational, and hay or silage is typically produced with one or two annual cuts. Fertilization, especially with nitrogen, can increase yield but may reduce plant diversity if overused. Drainage, pasture improvement, and selective cultivar choice influence productivity and resilience to drought or cold.

Ecology and biodiversity: grasvelden provide habitat for a range of insects, birds, and soil organisms, but species richness is influenced by mowing frequency, grazing intensity, and nutrient input. In many regions, biodiversity benefits are maximized by diverse sward compositions and periodic restoration or set-aside areas.

Threats and conservation: intensification, abandonment, and nutrient enrichment can decrease diversity and alter ecosystem function. Conservation approaches include restoration of species-rich meadows, agri-environment schemes, and appropriate mowing or grazing regimes.
