“…The obtained data imply that those smaller mires originated in the middle to late Holocene (between 3301 BC to AD 1137 according to radiocarbon dating), and that there was a strong human impact on vegetation since the Middle Ages, enhanced by a drainage network built in the 19th century. Soil studies carried out by [26,27,[29][30][31][32] revealed internal layering of the phytogenic sediments and their degradation due to draining of the mires. Since all those studies provided information on mire subsurface structure limited to randomly located boreholes, the actual morphology of the phytogenic sediment basement and their internal structure remain unknown.…”

“…As a consequence of climate change and draining, mires have become more susceptible to wildfires, which are especially difficult to tackle when smouldering fires develop [6,7]. The need for protection of wetlands is undisputable at present, and efforts are being made to restore local hydrological systems and original ecosystems, e.g., by damming drainage ditches, as has occurred in the Stolowe Mountain National Park area in Poland [8,9]. One of the key problems in the protection and restoration of drained mires is that anthropogenic changes have obliterated their morphological and environmental features, making their original boundaries difficult to determine in the field.…”

Long-term draining of peatlands results in transformation of vegetation and obliteration of their morphological features. In many areas, efforts are made to restore the original ecosystems and increase their water retention potential. Using combined analyses of a LiDAR-based digital terrain model (DTM), colour-infrared (CIR) imagery data, ground-penetrating radar (GPR) data and electrical resistivity tomography (ERT) data, we tested the applicability of these methods in outlining the extent and subsurface structure of drained mires located in the Stolowe Mountains National Park area, Poland. The LiDAR-DTMs enabled parameterisation of physiographic features of the mires and determination of their extent, runoff directions and potential waterlogging areas. CIR analysis enabled classification of vegetation types. GPR prospecting revealed the bedrock morphology, thickness and internal structure of the peat deposits, showing that this technique can also provide data on variability in the decomposition of phytogenic deposits. The obtained ERT sections indicate both the thickness of peat deposits and variability in the bedrock internal structure. The results show that integrated analyses of data obtained with different methods can be an effective tool in outlining the original extent of peatlands, with potential application in the planning of peatland ecosystem restitution.

“…In contrast, peat soils characterized by low mineral nutrient content, low pH, low soil oxygen content and high soil water content enhance plant communities dominated by peat mosses (Sphagnum spp.) (Bragazza and Gerdol, 2002;Glina et al, 2019;Bengtsson et al, 2021).…”

Draining peatlands for forestry in the northern hemisphere turns their soils from carbon sinks to substantial sources of greenhouse gases (GHGs). To reverse this trend, rewetting has been proposed as a climate change mitigation strategy. We performed a literature review to assess the empirical evidence supporting the hypothesis that rewetting drained forested peatlands can turn them back into carbon sinks. We also used causal loop diagrams (CLDs) to synthesize the current knowledge of how water table management affects GHG emissions in organic soils. We found an increasing number of studies from the last decade comparing GHG emissions from rewetted, previously forested peatlands, with forested or pristine peatlands. However, comparative field studies usually report relatively short time series following rewetting experiments (e.g., 3 years of measurements and around 10 years after rewetting). Empirical evidence shows that rewetting leads to lower GHG emissions from soils. However, reports of carbon sinks in rewetted systems are scarce in the reviewed literature. Moreover, CH4 emissions in rewetted peatlands are commonly reported to be higher than in pristine peatlands. Long-term water table changes associated with rewetting lead to a cascade of effects in different processes regulating GHG emissions. The water table level affects litterfall quantity and quality by altering the plant community; it also affects organic matter breakdown rates, carbon and nitrogen mineralization pathways and rates, as well as gas transport mechanisms. Finally, we conceptualized three phases of restoration following the rewetting of previously drained and forested peatlands, we described the time dependent responses of soil, vegetation and GHG emissions to rewetting, concluding that while short-term gains in the GHG balance can be minimal, the long-term potential of restoring drained peatlands through rewetting remains promising.

“…Within peat ecosystems, many community activities are carried out, especially those that are related to the social economy. Related research results were carried out [14,15,[19][20][21][22][23]. Regarding land conservation and management, research that has been carried out include studies [9][10][11][12].…”

The majority of regions in Riau Province are coastal areas and many communities live on land that is dominated by peat. Peat ecosystems have unique characteristics, as they are classified as wetland areas, while also possessing regions of terrestrial land. Poor maintenance of these ecosystems can cause a variety of issues such as forest fires, drought, flooding, biodiversity loss, increasing emissions, climate change, and social community changes. The purpose of this paper is to formulate a model of peatland utilization based on local wisdom and community welfare, in an effort to support the sustainable management of peat ecosystems in Riau Province. The main commodities of the coastal community are agriculture, coconut, rubber, oil palm, sago, coffee, cocoa, areca nut. Therefore, an understanding of the use of peatlands is needed. This is to prevent damage to the peatland ecosystem, maintain biodiversity, store carbon, produce oxygen, and manage water. Policies and strategies for managing the peat ecosystem are carried out through the development of socio-economic and community culture to realize people's welfare based on local wisdom. The management and use of peatlands have contributed to the economy, even as the main source of livelihood for coastal communities. Utilization of peatlands based on local wisdom can maintain a sustainable peat ecosystem.
