Abstract

In order to increase knowledge about the vegetative structure and environmental conditions, two coastal areas (north and south) in Sonora, Mexico, where Salicornia bigelovii develops in natural form were investigated. Based on the abundance of Salicornia, three locations were selected in the two areas. Transects in each of the three sites were developed. The sediments in the northern areas showed higher values compared with the south areas of Sonora in organic matter. Plant biomass, density, height and frequency of occurrence were higher in frequently flooded areas compared to sparsely or less often by the tides. The average total biomass ranged from 2.23 to 6.33 kg (dry weight) m-2 and is composed primarily of surface components. The maximum values of biomass of Salicornia were observed in February to May in both areas. The growth of Salicornia bigelovii is influenced mainly by the frequency of flooding, duration of exposure to air during low tide, rainfall, salinity and salt content of the ambient water and sediment, respectively. The carbon content increased with plant age, while protein content decreased by 233.6%. The steady increase in human pressure on coastal areas where Salicornia and other halophytes growth, require immediate protection order to prevent vulnerabilities in their populations.
