“…Soil environmental characteristics such as soil salinity, total nitrate, and clay content of P. australis in tidal marsh were significantly lower than the soil environment of Suaeda community in lower area (Lee et al 2016(Lee et al , 2018. Overall soil pH, electric conductivity, and other exchangeable cation concentrations were lower than the previous studies on the tidal marsh (Ihm et al 2007;Lee et al 2016).…”

To assess the environmental factors determining the zonation between Phacelurus latifolius and Phragmites australis, vegetation survey and soil analysis were performed at a tidal marsh. The vegetation of the tidal marsh was classified into P. latifolius and Suaeda japonica dominated quadrats, P. latifolius and P. australis dominated quadrats, P. australis dominated quadrats, and P. australis and other land plants dominated quadrats. The density of P. latifolius (83.7 ± 5.5 shoots m −2) was higher than that of P. australis (79.3 ± 12.1 shoots m −2) in each dominated quadrat but height of two species were similar. Soil environmental characteristics of P. latifolius dominated quadrats appeared to be affected by tide based on higher soil electric conductivity (EC PL = 1530 ± 152 μS cm −1 ; EC PA + PL = 689 ± 578 μS cm −1 ; EC PA = 689 ± 578 μS cm −1) and lower pH (pH PL = 5.96 ± 0.16; pH PA + PL = 6.28 ± 0.31; pH PA = 6.38 ± 0.22). In redundancy analysis, environmental characteristics of P. latifolius dominated quadrats and P. australis dominated quadrats were clearly separated and those of P. latifolius and P. australis co-dominated quadrats were similar to P. australis dominated quadrats. From our investigation, P. latifolius showed relatively high competitiveness when compared to P. australis in lower tidal zone rather than upper tidal zone. Zonation of P. latifolius and P. australis seems to be a transitional zone between halophytes and land plant species.

“…For example, to calculate the effect of m , evaporation (ET o ) was calculated using equation 6 of Allen et al and has an annual mean value of 2380 (mm) [35]; Pedotransfer functions were used to estimate the soil's field capacity and wilting point [36], which were determined as 35% and 22%, respectively. Furthermore, the EC e data was gathered from the literature to determine the impact of soil salinity on the rate of decomposition [37]. Due to the study areas proximity and similar climatic conditions, the difference in mean value of is very close, and almost equal.…”

Since coastal wetlands have been severely degraded and polluted by human activities, they have increasingly become a significant source of greenhouse gases (GHGs), so understanding the characteristics of their emissions is critical for devising future climate change mitigation strategies. This study modified a model based on carbon balance to forecast carbon stored and CO2, CH4 emissions in four types of typical tidal flats—Phragmites australis (PA), Spartina alterniflora (SA), Suaeda japonica (SJ), and Bare Tidal Flat (BTF) in Korea’s Ganghwa province from 2017 to 2047. The model was built using biomass data from salt plant species collected in different locations. The results indicate that the total annual simulated flow of CH4 increased over time in all four areas, most notably in SA, while CO2 remained relatively stable. The mean CO2 and CH4 fluxes in the four types of representative tidal flats were in the range of 0.03 to 19.1 mg m−2 d−1 and 0.007 to 5.23 mg m−2 d−1, respectively, across all seasons. Besides, the results indicate that the amount of carbon accumulated in the top soil increases linearly over time in nearly all areas studied, ranging from 0.01 to 0.13 (kgC m−2 yr−1). In general, the study provides a model for Korean tidal flats that incorporates carbon storage and GHG emissions in the intertidal zone in order to develop potential GHG reduction scenarios.

“…Whether inland saline habitats have natural origins or owe their existence to the salt industry [ 8 ] or secondary salinization [ 9 ], their flora has a high representation of specialists (halophytes). They are well-adapted to such permanent abiotic stresses as soil salinity and an unstable water regime [ 10 ] and are excellent indicators of soil salinity [ 11 , 12 , 13 ]. Low species richness and high vegetation variability of saline habitats is governed by the salt content and moisture of the soil [ 14 ] which are key factors determining wetland and steppic saline habitats.…”

Little is known about the suite of ecological conditions under which characteristic species may continue to develop under the pressure of recent habitat deterioration. We aimed to determine the niche of three indicator species of the priority habitat Pannonic salt steppes and to find out how their vegetation composition, land use, and soil chemistry mirror the current condition of their typical habitat. A plot-based vegetation survey was conducted in degraded and in pristine (reference) inland salt steppes in East-Central Europe. We confirmed decreased habitat quality at their northern geographical limit. Most of the sites there showed a strong prevalence of generalists (e.g., Elytrigia repens) and lack of specialists, both resulting from lowered habitat extremity and inappropriate land use (abandonment). A small proportion of plots (19%) were in the same good condition as the reference vegetation in the central area. Soil analyses revealed that the studied halophytes are able to persist on desalinized soils if the land use is suitable. The occurrence of the annual Camphorosma annua (Amaranthaceae) was driven largely by abiotic stress; grazing alone is insufficient for its long-term persistence, while the perennial Artemisia santonicum (Asteraceae) and Tripolium pannonicum (Asteraceae) have higher survival chances as they are able to coexist with generalists. Overall habitat quality can be reliably determined from the analyzed ecological conditions of indicator species. The outcomes of the presented work are relevant for conservation practice and can serve as a quick tool for assessing the current stage of other grassland habitats.
