As one of the main terrestrial carbon reserves, peatland ecosystems are of the great interest in obtaining highly detailed orthophotoplans. At the same time, there is a lack of publications devoted to the total carbon dioxide fluxes in each type of bog microforms. This paper presents the results of our study, which aimed to develop methods for mapping peatland microlandscapes and for estimation of integral carbon dioxide fluxes between the peatland surface and the atmosphere. Based on a highly detailed orthophotoplan compiled using unmanned aerial vehicles, we assessed the areas of major microform groups (swamps, hollows, and ridges) in a bog located in the Central Forest State Nature Biosphere Reserve (European Russia). The classification accuracy ranged from 79% to 93%. The areas of ridges, hollows, and swamps were 0.16 km 2 , 0.32 km 2 , and 0.12 km 2 , respectively. To make an integral estimation of carbon dioxide fluxes, we used earlier data on carbon dioxide emissions (ecosystem respiration), uptake (gross ecosystem exchange), and balance (net ecosystem exchange) measured by soil chamber method on representative experimental plots of respective microform types. After recalculating fluxes to areas of microforms, the integral values for different classes in the summer seasons of 2014, 2016 and 2017 were 15-91 kg CO 2 × h-1 for ecosystem respiration, 21-190 kg CO 2 × h-1 for gross ecosystem exchange, and from-122 kg CO 2 × h-1 to 41 kg CO 2 × h-1 for net ecosystem exchange. The results of the study confirmed that highly detailed orthophotoplans, obtained with the use of unmanned aerial vehicles, make it possible to distinguish the boundaries of such bog microforms as swamps, hollows and ridges with a high accuracy, despite the presence of some errors in the classification. The study of the structural and functional organisation of the bog should be carried out with considering its seasonal and interannual dynamics as well as all microform types.

The goal of this rapid response assessment, carried out on behalf of UN Environment and based on the efforts of more than 30 contributors, is to raise awareness about the importance of the world's peatlands and to encourage immediate action to preserve them.

However, because the character of this diversity differs from that of other ecosystem types, the value of peatlands for biodiversity has often been overlooked. Fundamentally, this arises because peatland ecosystems direct part of the energy captured by primary production into long-term storage within a peat layer, and thus establish a structural and functional basis for biodiversity maintenance that is not found elsewhere. This article examines the far-reaching implications for the assessment of peatland biodiversity as well as for the drivers, methods and targets of peatland conservation and restoration initiatives. It becomes clear that a robust framework for the management and restoration of peatland biodiversity must be founded in structuralfunctional ecosystem analysis, and such a framework is developed. The authors draw on a broad base of historical and contemporary lit...

The history of forested peatlands formation is comparable in duration to that of large peatbog massifs formation. An increase in wood-macrofossils content in peat is characteristic of warm periods of the Holocene. Conversely, a decrease in wood-macrofossils content accompanied by an increase in sphagnum moss remains, intensive growth of the deposit, and paludification of the adjacent forests were timed to the cold periods. The climatic factor was shown to determine the general direction of forested peatlands development, whereas the hydrological features of the site determined the variety of scenarios and resistance to environmental changes.

An annotated list and dicussion on general bryophyte complexes of reserve are given. A collection of V. Medvedskaya-Romanenko, made in 1938 allows evaluation of changes in bryoflora since that time. The main changes: (1) epixylic hepatic flora has become poorer, and some rare species (Bazzania tricrenata, Di plophyllum taxifolium) are probably disappeared; (2) Hamatocaulis vernicosus, a moss of minerotrophic bogs, has not been recollected; (3) southern epi phytic mosses have probably become rarer (Anomodon viticulosus, Hypnum vaucheri haven't been found); Leucodon sciuroides and Anomodon longifolius were found on only one trunk each. Pylaisiella selwynii can be considered to have recently become established in the flora of this area.

The ES values were defined through stakeholder analysis, while the mapping was based on the biophysical traits of the ecosystems and related spatial distribution of ecosystem functions. The mapped ecosystem values differ from the perceived ones. The assessment identified conflicting land uses and groups of stakeholders, including Indigenous Peoples vulnerable to future climate change-induced deficits in access to ES. The ES that are important for climate change mitigation and adaptation are not valued highly by Indigenous Peoples. ES mapping is suggested as an appropriate method for the development of straightforward recommendations for Nature Park management.

In this regard, zoning legitimately balances influential stakeholders versus weak ones, and can leverage stakeholders to exercise their rights. This study explores how various stakeholders employ zoning in the Numto Nature Park in the oil-rich Russian Khanty-Mansi Autonomous Okrug-Yugra to advance their interests and how they use scientific information to achieve this. Through stakeholder interviews, analysis of electronic media and literature review, we conclude that a participatory and sciencebased zoning exercise stimulates the necessary deliberation. However, legal ambiguity, deficient law implementation and informal practices limit the zoning's potential to balance stakeholders' interests. All the stakeholders calculatingly used scientific information to legitimize their own ambitions, activities and claims. Hence, zoning and the underlying information claims should be interpreted as both a resource and a battleground in nature-use conflicts.

They often present the best preserved areas, habitats, and shelters for biological species. Peatlands form a specific environment and play a significant part in the regulation of climate due to their participation in the water and carbon cycles. They are characterized by a wide range of biodiversity; spatial heterogeneity; and a particular structural and functional integrity, which is determined by the interrelations between excessive moisture, peatland vegetation, and peat. The scope of all the features mentioned presupposes a specific, often ambiguous, response of peatlands and their biodiversity to climate change.
