ABSTRACT Rewetting is considered a strategy for mitigating carbon dioxide (CO 2 ) emissions from drained peatlands, with associated climate benefits often derived by applying emission factors (EFs). However, data rewetted sites are lacking, particularly boreal peatland forests established on nutrient‐poor fens. Instead, their EFs have been developed primarily based natural mires, implying similar (C) cycles. In this study, we integrated eddy covariance measurements of ecosystem CO and methane (CH 4 exchanges dissolved C export estimates to compare the net balance (NECB) recently minerogenic two nearby undisturbed fen‐type mires in northern Sweden. We found that was an annual source mean NECB +77 ± 34 g m −2 year −1 (±SD) over initial 3 years following rewetting. comparison, were nearly neutral or sink 3‐year ranging between +11 −34 . The declined about half third coinciding increase gross primary production. Annual CH steadily increased but remained at 32% 49% first year, respectively, relative mires. further noted differences key environmental response functions fluxes peatlands.

Thus, our study demonstrates may not immediately resemble This highlights need separate dynamic improve short‐term benefit rewetting measures.

The fires of the forest and peatland are serious environmental threats. In addition to damaging ecosystems, these also cause extensive health, social, economic impacts. middle mitigation efforts, social capital plays an important role in strengthening capacity local communities prevent deal with disasters. This study aims explore fire using a qualitative approach. case was implemented Tanjung Belit Village, Bengkalis, involving in-depth interviews stakeholders, such as Disaster Care Community (MPB), communities, government. results indicate that form trust, shared norms, networks key elements driving collective action increasing effectiveness programs. active involvement understanding wisdom, synergy between actors main drivers prevention efforts success fire. concludes is strategy must be prioritized community-based disaster policies achieve sustainability.

Restoration of forestry‐drained peatlands aims to restore near‐natural hydrology and peat‐forming vegetation. Particularly, Sphagnum mosses are important for carbon (C) sequestration through peat accumulation. We investigated the new moss layer in 18 restored circa 10 years after restoration. The sites were monitored vegetation, water level, chemistry. post‐restoration had grown on average 14.9 ± 5.2 cm thickness, measured from cores. An independent method using rooting depths small pines ( Pinus sylvestris ) indicated a 15.4 5.4 thickness newly formed layer. dry mass was 2882 1318 g/m 2 . Apparent accumulation rates 132.5 59.8 g m −2 yr −1 C 2.36 0.91 nitrogen (N). Growth significantly connected mire type, latitude, quality. Thick cover developed well under relatively wet baseline conditions with level rise near pre‐restoration surface. Moss growth generally greater open “oligotrophic” than forested or “mesotrophic” sites. N concentration, pH, electric conductivity pore correlated negatively growth, while phosphorus showed no significant correlations. Our results indicate that thick forms rapidly during first successful restoration, commonly exceeding those pristine bogs. south‐boreal acidic, nutrient‐poor where forest drainage has been unsuccessful appears most promising regarding by mosses.

Aapa mires are distinctive base‐enriched northern peatland systems, often with pronounced flark‐string (deep‐pool) surface features. used by specialist breeding migratory waterbirds (particularly Broad‐billed Sandpiper Calidris falcinellus , Jack Snipe Lymnocryptes minimus Taiga Bean Goose Anser fabalis and Pintail Anas acuta ) support high densities of other nesting wader species (Wood Tringa glareola Spotted Redshank erythropus Ruff pugnax Common Gallinago gallinago Curlew Numenius arquata Whimbrel phaeopus compared landforms. Remote sensing, palynology peat stratigraphy studies confirm rapid massive loss aapa through recent drainage, but now also climate change. Botanists report that warming has caused enhanced successional expansions in ombrotrophic raised mire vegetation to engulf mires, destroying their unique nutrient characteristics. As the waterbird associated cannot survive on acidic base‐poor this ecological change places populations jeopardy. While acknowledging need reduce means, these changes prioritize for international cooperation extend improve site‐safeguarding intact restoration damaged as well effective conservation affected avian throughout full annual cycle safeguard them, bird communities future generations.
