“…P. australis is a cosmopolitan wetland grass typically associated with standing water up to 1 m deep or even as a floating mat but also with damp ground or wet soil, a proxy indication of previously inundated land. The connection between the presence and abundance of P. australis and wetland soil types is well established, as a voluminous literature is available on the strong correlation between the two [39][40][41][42][43][44][45][46]. In suitable habitat conditions, e.g., hot summers and fertile growing conditions, P. australis effectively spreads (5 m or more per year) through a strong network of rhizomes, horizontal runners putting down roots at regular intervals, and a rich-soil seedbed.…”

“…Its competition-related functional phenotypic traits [47,48], e.g., fast growth rate, low wood density, high leaf area, and fast recovery after disturbance, besides its worldwide spread, may explain "reeds" sensu lato persistence, expansion, and invasiveness [46][47][48][49][50][51][52][53]. Then, one might easily identify the polysemic status of the species in the literature according to authors' research and conceptual priorities, e.g., conservation or biogeochemistry [54,55].…”

This study explores the historical occurrence of wetland ecosystems in Greece by using recurring Phragmites australis (common reed) burnings as an indicator. Phragmites australis, a plant closely associated with wetlands, provides excellent insights into wetland distribution. We establish a substantial association between reed fires and historical wetland existence in Greece using geographical and statistical analysis, with these fires exhibiting remarkable constancy across time. Using Corine land-cover (CLC) data, we extend our analysis into land-use dynamics, demonstrating that places with the highest reed-bed-fire rates were originally wetlands, particularly those converted into permanent irrigated land and areas with complex agriculture patterns. We find spatial commonalities between reed fires and past wetland existence by analyzing fire occurrence across three main categories: reed fires, agricultural land fires, and grassland fires. Historical records of wetland conversion into agricultural land (or land reclamation works) in locations such as Yianitsa and Kopaida give context to our findings. Visualizations confirm the clustering of reed fires around these converted agricultural regions. In summary, our study offers a unique indicator based on Phragmites australis burnings that can be used to identify previous wetland-type ecosystems, with Mediterranean-wide implications. Despite data constraints, this study adds to the conversation about wetland preservation and sustainable land-use management.

This study determines the extent of degradation of soils in Khubelu wetland in Lesotho and the impact this may have on its water purification potential. 72 soil samples are collected at different sites and depths around the wetland and characterized for different properties. The values of these properties are then used to determine the chemical degradation index (CDI) of the wetland soils. The soils are non‐saline (electrical conductivity < 0.25 mS cm−1), mostly acidic (4.5 < pH < 5.22) with moderate organic matter content (2.06–3.9%). Soil properties vary with depth and from upstream to downstream of the wetland. Values for soil CDI are 3.42, 3.25, and 3.06 for soils from upstream, midstream, and downstream of the wetland respectively, indicating a decrease in soil degradation from upstream to downstream. The dominance of emergent vegetation in the wetland indicates a potential to get rid of sediments in wetland influents but the soil characteristics may present a challenge in the removal of nutrients and organic and inorganic pollutants from these influents. The characteristics of the soils and the extent of soil degradation present some challenges in the wetland’s ability to filter out nutrients and organic and inorganic pollutants.

Disparities in pH, conductivity, organic carbon (OC), nutrients, and moisture between the Asan Wetland and its periphery in the Western Himalaya, India, highlight the need to investigate influencing factors. This study thus addresses two gaps: (1) identifying key drivers for alkaline pH and elevated wetland concentrations and (2) understanding how different values outside the wetland relate to ecological processes. Asan Wetland soil samples, collected on April 15, 2023, underwent analysis for pH, electrical conductivity (EC), organic carbon (OC), organic matter (OM), available nitrogen (N), available phosphorus (P), potassium (K), sodium (Na), calcium (Ca), moisture content (M), total organic carbon (TOC), and total organic matter (TOM) using standard laboratory procedures, APHA, CPCB, and standard manual techniques. Within the wetland, results indicated that the soil is more alkaline (pH 8.50 ± 0.13) than the periphery in the concentrations of EC, N, K, and M were found to be higher compared to the corresponding concentrations outside the wetland, with mean values of 1.10 ± 0.15 ds/m, 364 ± 117.13 kg/ha, 86.42 ± 21.64 kg/ha, and 20.87 ± 1.50%, respectively. Conversely, outside the wetland, higher values of OC, OM, P, Na, Ca, TOC, and TOM were recorded (0.39 ± 0.23%, 0.66 ± 0.39%, 0.82 ± 0.35 ppm, 80.45 ± 8.46 ppm, 268.12 ± 61.12 ppm, 56.80 ± 0.33%, and 97.70 ± 0.57%, respectively). pH, EC, K, Ca, Na, and moisture content variations indicate location‐based differences. pH, TOM, TOC, and soil moisture were positively correlated within wetlands but negatively correlated with Na and N. In addition, moisture was positively correlated with pH and N but negatively correlated with Ca, K, Na, and P. The study concluded that the Asan Wetland exhibits distinct soil characteristics compared to its periphery, exhibiting location‐based differences while emphasizing these factors' interconnectedness.
