Cornish Red Data (2009)

The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.

Atriplex longipes - Long-stalked Orache



Range & Status

Native; European Boreal-montane species; known from a few dozen coastal sites in

England and Wales and at one site in Cornwall.

Regional Distribution

Recorded at only one location in Penpoll Creek (SX15). Only four plants were seen in

1991 and two in 2004.

Habitat & Ecology

An annual species of the upper reaches of saltmarshes, in silty substrates, flooded with brackish water during highest tides. It grows along the border of a creek with other saltmarsh plants.

Threats

The colony is very small. Hybridisation with A. prostrata ( Atriplex x gustafssoniana ), could represent a threat as the hybrid has been recorded near the site, and in two other Cornish estuarine sites (West Looe River, SX25; Copperhouse Pool, SW53).

Conservation

Not known.
