Sisymbrella aspera is a widespread and abundant species with stable populations. It is not believed to approach the criteria for listing in a threatened category. It is therefore listed as Least Concern.
|Range Description:||Sisymbrella aspera is a western Mediterranean species. |
In the Mediterranean region it is found in Portugal, Spain, France, Morocco and Algeria. Its extent of occurrence surpasses 1,000,000 km², with several locations.

mountains of oriental Morocco and the Rif;
- Algeria: fairly common, occurring in the Constantinois Saharan Atlas (Aurès) and the Oranais Tellien Atlas (Tlemcen mountains);
- Spain: very common, present in 195 sites;

|Current Population Trend:||Stable|
|Habitat and Ecology:||It is a perennial plant (Hemicryptophyte) that inhabits the edges of rivers, brooklets, springs, pools, ditches and other habitats that are humid in winter. Flowering occurs during spring.|
|Major Threat(s):||The agricultural usage and drainage of this species' habitat are the main threats. Droughts are likely to affect the species, in addition to intrinsic factors such as its restricted range and limited dispersal.|
|Conservation Actions:||In France, the species is under regional protection (Rhones-Alpes and Ile-de-France). There are no other conservation measures in place except for research on taxonomy, habitat status, biology and ecology. More information on population numbers and range as well as habitat maintenance and conservation are needed.|
