NVC community SD2 (Honkenya peploides - Cakile maritima strandline community) is one of two strandline community in the British National Vegetation Classification system.
It is a fairly widely distributed community. There are no subcommunities.
Two constant species, Sea Rocket (Cakile maritima) and Sea Sandwort (Honkenya peploides), are found in this community.
One rare species, Ray's Knotgrass ( Polygonum oxyspermum ssp. raii), is also associated with the community:
This community is found in many localities in Scotland, on the east coast of England, in North Wales, the Isle of Man, and the Isles of Scilly.

Honckenya peploides, the sea sandwort (UK) or seaside sandplant (Canada), is the only species in the genus Honckenya of the flowering plant family Caryophyllaceae.

Cakile maritima, sea rocket or European searocket, is a common plant in the mustard family Brassicaceae. It is widespread in Europe, North Africa and western Asia, especially on coastlines. It can now be found in many other areas of the world where it has been introduced. It is present on the west and east coasts of North America, where it has the potential to become a noxious weed. This is an annual plant which grows in clumps or mounds in the sand on beaches and bluffs. The shiny leaves are fleshy, green and tinted with purple or magenta, and long-lobed. It has white to light purple flowers and sculpted, segmented, corky brown fruits one to three centimeters long. The fruits float and are water-dispersed.
Wingletang Down is a Site of Special Scientific Interest (SSSI) on the southern side of the island of St Agnes in the Isles of Scilly, England, UK, which is noted for its biological characteristics. The site is managed by the Isles of Scilly Wildlife Trust and is within the Isles of Scilly Heritage Coast and the Isles of Scilly Area of Outstanding Natural Beauty. It is the only site in Great Britain and Ireland for the small fern, least adder's–tongue. As of 11 September 2009 the SSSI was considered to be in ″unconditional recovering″ condition because European gorse and bramble are at unacceptable levels.
The Eastern Isles are a group of twelve small uninhabited islands within the Isles of Scilly Area of Outstanding Natural Beauty, part of the Scilly Heritage Coast and a Site of Special Scientific Interest (SSSI) first designated in 1971 for its flora and fauna. They have a long period of occupation from the Bronze Age with cairns and entrance graves through to Iron Age field systems and a Roman shrine on Nornour. Before the 19th century, the islands were known by their Cornish name, which had also become the name of the largest island in the group after the submergence of the connecting lands.
