“…Lishawa et al (2019) suggested that restoration techniques of cattail dominant areas should focus on periodic treatments including biomass removal, in order to preserve the native biodiversity. Vroom et al (2018) proposed that T. latifolia can be utilized for the restoration of peatlands after their rewetting, because of the species capacity to control nitrogen and phosphorus concentrations from surface and pore water, as well as regulate CH 4 and N 2 O emissions. Nevertheless, the selection of cattail species for potential phytoremediation must be based upon the species invasiveness risk (Bonanno and Cirelli, 2017;Gikas et al, 2018).…”

Changes in weed communities due to changes of climate and agricultural practices have already been indicated. Cattail (Typha spp.) is considered as a noxious invasive species with an increasing dispersal in Greece and other countries, where it starts to become a serious problem particularly in wet areas and especially for perennial crops. Pot and field experiments were conducted in order to evaluate the efficacy of several herbicides and mowing against cattail. The results of the present study revealed the low efficacy of several herbicides (like imazamox, 2,4-D and MCPA) against Typha spp. plants. On the other hand, pot experiments showed that especially glufosinate and glyphosate (in high rate) killed the majority of cattail plants grown by rhizomes. Moreover, they key result of our field experiment is the strong indication of a synergistic action of mowing and chemical control, especially in the case of glufosinate and glyphosate. The case of Typha spp. confirms that the integration of several control methods and agronomic practices may ensure an efficient, long-term management of noxious and invasive weeds.

Large-scale re-establishment of wetland buffer zones (WBZ) along rivers is regarded as an effective measure in order to reduce non-point source nitrogen (N) and phosphorus (P) pollution in agricultural catchments. We estimated efficiency and costs of a hypothetical establishment of WBZs along all watercourses in an agricultural landscape of the lower Narew River catchment (north-eastern Poland, 16,444 km2, amounting to 5% of Poland) by upscaling results obtained in five sub-catchments (1087 km2). Two scenarios were analysed, with either rewetting selected wetland polygons that collect water from larger areas (polygonal WBZs) or reshaping and rewetting banks of rivers (linear WBZs), both considered in all ecologically suitable locations along rivers. Cost calculation included engineering works necessary in order to establish WBZs, costs of land purchase where relevant, and compensation costs of income forgone to farmers (needed only for polygonal WBZs). Polygonal WBZs were estimated in order to remove 11%–30% N and 14%–42% P load from the catchment, whereas linear WBZs were even higher with 33%–82% N and 41%–87% P. Upscaled costs of WBZ establishment for the study area were found to be 8.9 M EUR plus 26.4 M EUR per year (polygonal WBZ scenario) or 170.8 M EUR (linear WBZ scenario). The latter value compares to costs of building about 20 km of an express road. Implementation of buffer zones on a larger scale is thus a question of setting policy priorities rather than financial impossibility.

“…The fate of organic carbon and nitrogen is also influenced by microbial communities associated with methane cycling and nitrogen cycling in which CH 4 and N 2 O are produced [13, 14]. While decent efforts were invested to investigate the influence of rewetting on the emissions of greenhouse gases (GHGs) [15-18], extracellular enzyme activities [19], dissolve organic carbon [20, 21], and water chemistry [15, 19], little is known about the changes of microbial communities driving these processes.…”

23Background: Drainage of high-organic peatlands for agricultural purposes has led to increased greenhouse 24 gas emissions and loss of biodiversity. In the last decades, rewetting of peatlands is on the rise worldwide, 25 to mitigate these negative impacts. However, it remains still questionable how rewetting would influence 26 peat microbiota as important drivers of nutrient cycles and ecosystem restoration. Here, we investigate the 27 spatial and temporal dynamics of the diversity, community composition and network interactions of 28 prokaryotes and eukaryotes, and the influence of rewetting on these microbial features in formerly long-29 term drained and agriculturally used fens. Peat-soils were sampled seasonally from three drained and three 30 rewetted sites representing the dominating fen peatland types of glacial landscapes in Northern Germany, 31 namely alder forest, costal fen and percolation fen. 32Results: Costal fens as salt-water impacted systems showed a lower microbial diversity and their microbial 33 community composition showed the strongest distinction from the other two peatland types. Prokaryotic 34 and eukaryotic community compositions showed a congruent pattern which was mostly driven by peatland 35 type and rewetting. Rewetting decreased the abundances of fungi and prokaryotic decomposers, while the 36 abundance of potential methanogens was significantly higher in the rewetted sites. Rewetting also 37 influenced the abundance of ecological clusters in the microbial communities identified from the co-38 occurrence network. The microbial communities changed only slightly with depth and over time. According 39 to structural equation models rewetted conditions affected the microbial communities through different 40 mechanisms across the three studied peatland types. 41 Conclusions:Our results suggest that rewetting strongly impacts the structure of microbial communities 42 and, thus, important biogeochemical processes, which may explain the high variation in greenhouse gas 43 emissions upon rewetting of peatlands. The improved understanding of functional mechanisms of rewetting 44 in different peatland types lays the foundation for securing best practices to fulfil multiple restoration goals 45 including those targeting on climate, water, and species protection. 46
