“…The highest EC was c. 60-80 mS cm −1 in late spring and summer, corresponding to c. 600-800 mM NaCl, which are values that have been reported as growth-limiting for S. europaea (>400 mM NaCl) [41]. The survivorship curve pattern for S. ramosissima in the depressed zones could be assimilated to Types II or III of [34] and describes a situation in which individuals are affected by high mortality rates from the beginning of their adult stage. Similar curves were observed by [25] for populations of S. ramosissima with densities of 3000-9000 plants m −2 in salt pans in the Odiel Marshes.…”

Halophyte species growing under stressful conditions, such as the annual species of the Salicornia 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 environmental matrix and population dynamic of four Salicornia ramosissima populations growing at two elevations in salt pans under a Mediterranean climate. In elevated areas, S. ramosissima populations presented maximum plant densities of between 628–6288 plants m−2 that remained almost constant until fruiting. In contrast, populations in depressed zones presented five-times greater soil-seed-bank densities and maximum plant densities than populations in elevated zones. In this context, populations in depressed zones lost c. 60% of their maximum plant densities from the end of spring and through summer. In whatever way the environmental matrix seemed to control the population dynamic of S. ramosissima in depressed zones, the effects of a stressful environment would interact with plant densities. 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 natural populations of S. ramosissima.

“…[33]. Although in some populations of S. ramosissima outbreeding by wind pollination is not completely avoided due to the existence of protandry [34], Salicornia species are seen as selfing species whose populations can be considered homozygous lineages with low genetic diversity [16,35,36].…”
