Threats

Major Threats

The pollution of water, as well as the intensive pumping of groundwater for irrigation in the Souss plain, threaten the habitat as this results in increased salinity that could lead to important changes in the vegetation.

Wikipedia

Spergularia media

Spergularia media (syn. S. maritima) is a species of flowering plant in the pink family known by the common name greater sea-spurry. It is native to Eurasia and the Mediterranean, where it grows in many types of habitat, including disturbed areas, including places with saline substrates, such as salt marshes and beaches. It is known in many other parts of the world as an introduced species and a common roadside weed. In North America it is a "highway halophyte", often springing up at the margins of roads that are heavily salted in the winter.[1] It is an annual or perennial herb producing a narrow stem lined with fleshy linear leaves. The small flowers have five pointed sepals and five oval white or pink-tinged petals. The tiny seeds have winged margins.

Notes

Comments

Although a proposal to reject Spergularia media as a confused name (J. Lambinon 1981) was rejected, some authors still favor that argument, preferring to use the name S. maritima for this species.

Spergularia media is one of the “highway halophytes” (A. A. Reznicek 1980) that have spread along highways that are heavily salted during the winter, where saline areas have been created. Spergularia distribution has been investigated in Ohio (A. W. Cusick 1983), where such records were first noted in the early 1970s.
