AB Halophyte species growing under stressful conditions, such as the annual species of theSalicornia genus, have been recognized as a source of metabolites of pharmacological and nutraceutical interest. Therefore, planning the extraction of individual plants from wild populations in a sustainable way is especially important in the case of annual species. We studied the environmentalmatrix and population dynamic of four Salicornia ramosissima populations growing at two elevationsin salt pans under a Mediterranean climate. In elevated areas, S. ramosissima populations presented maximum plant densities of between 628–6288 plants m−2that remained almost constant until fruiting. In contrast, populations in depressed zones presented five-times greater soil-seed-bank densitiesand maximum plant densities than populations in elevated zones. In this context, populations indepressed zones lost c. 60% of their maximum plant densities from the end of spring and throughsummer. In whatever way the environmental matrix seemed to control the population dynamic ofS. ramosissima in depressed zones, the effects of a stressful environment would interact with plantdensities. In this sense, we recorded the density-dependent mortality for the densest population(max. 51,558 plants m−2). Our results are useful for planning a sustainable harvesting of naturalpopulations of S. ramosissima
