The class Galio-Urticetea comprises nutrient-demanding highly productive perennial or in a few cases annual vegetation types of mesic to wet habitats, dominated by broad-leaved dicots. Many stands are species-poor and have a single dominant species. Some vegetation types within Galio-Urticetea are natural, e.g. those growing at the fringes of mesic forests and scrub, in canopy openings, on water banks, game trails and in places with a high density of animals. Other stands occur in anthropogenic habitats, e.g. on roadsides, in waste places, unmanaged parks and gardens or along the banks of regulated waterways. The class Galio-Urticetea includes a larger proportion of native species than other types of ruderal vegetation, and some of these are shared with mesic meadows or mesic forests. It is more common in cooler and wetter areas than the other classes of ruderal vegetation. At higher altitudes it is the most common type of ruderal vegetation.
