Occurrence

The distribution area includes Europe, Africa, West and Central Asia. It is a neophyte in Macaronesia, North and South America, Australia and New Zealand.

The tangled dock can be found scattered (and inconsistent) in patchy weed meadows, on ditches, banks, and also in fields. It loves nitrogen-rich, often moderately alkaline, moist, sandy, muddy or loamy-clay soils. It is absent in the rough areas of the lowlands and mountains. According to Ellenberg , it is a light plant, a moisture pointer, a pronounced nitrogen pointer and a class character of the creeping ostrich lawn or the flood lawn ( Agrostietea stoloniferae ). According to Oberdorfer , it appears in societies of the Agropyro-Rumicion, Bidention or the Atropetalia order.

It is a pioneer plant and can often cover backfilled soils with large stands within a short period of time. However, in contrast to the blunt-leaved dock ( Rumex obtusifolius ) and the curled dock ( Rumex crispus ), it can also be absent in entire regions.
