Abstract Mangroves are implemented as nature‐based solutions (NbS) for coastal protection, climate change mitigation (carbon sequestration) and other services. They play a core role in providing benefits biodiversity, livelihoods human well‐being. Ecological research has informed the use of mangroves NbS, but failure NbS projects often been due to misconceptions about mangrove ecology limited wide range ecological knowledge available. Enhanced spatial temporal variation processes, differentiation among tree species assemblages (including fauna microbial communities) provision ecosystem functions services, will support successful NbS. Knowledge responses interacting pressures uses zone resilient projects. Synthesis . The success can be improved with increased incorporation plants, animals microbes by sharing co‐producing within societies.

Abstract Precise identification of wetland boundaries has become increasingly important as society’s view ecology evolves. With climate change, various environmental issues have significantly impacted public discourse. One these “uncomfortable” questions is the establishment protection regimes in areas. To address this, accuracy and correctness determining are essential. This particularly relevant for land users, vegetation certain areas becomes protected if it grows wetlands or water zones. The exact boundary determined by a surveyor during measurements. However, such measurements often lead to errors, subjective determination can play significant role, along with factors moisture level at time measurement. As result, deviations occur, causing shift one direction another. Accurately ensures proper implementation requirements enables optimal use economic activities. During this research, were conducted different levels within wetland. carried out accordance legal regulations criteria boundaries. measurement data analyzed, discrepancies between presented, reasons inconsistencies discussed.
