raised bog - Opis:
- We pres ent the last mil len nium of his tory of a peatland lo cated in north ern Po land. Our re sults are based on two rep li - cate mono liths taken from a Bal tic raised bog. We ap plied a high-res o lu tion ap proach and ra dio car bon dat ing to the peat ma te rial to ob tain a de tailed palaeoenvironmental re con struc tion. To re con struct past peatland mois ture, we used three prox ies: tes tate amoe bae, plant macrofossils and pol len. De spite dif fer ent peat ac cu mu la tion and ex ten sive hi a tus in the for merly stud ied core, both mono liths show a sim i lar pat tern of changes. How ever, the core from this study pro - vides us with more de tailed data on S. fuscum dis ap pear ance which cor re lates well with the data from the other Bal tic bog, S³owiñskie B³oto. Our re search shows that pris tine Bal tic bogs can be dated to AD 1350. S³owiñskie B³oto palaeohydrology con firms AD 1300 as the be gin ning of the hy dro log i cal dis tur bance. In the case of the St¹¿ki and S³owiñskie B³oto bogs, the Lit tle Ice Age (LIA) is re corded be tween AD 1500 and AD 1800. How ever, this cli ma tic change might have been blurred by hu man im pact. In the case of the Bal tic bogs, their ref er ence vir gin state can be dated to AD 1200. Af ter this date, we ob served in creas ing hu man im pact and cli ma tic in sta bil ity con nected with the LIA. How ever, be tween AD 1800 and 1900, bogs were wet, most pos si bly due to cli ma tic forc ing. This fact sug gests that de spite hu man im pact, re cent peat de pos its can still re flect cli mate. Our re search pro vided in for ma tion re lated to the time of ex is tence, lo ca tion and char ac ter is tics of the nat u ral/pris tine state. High-res o lu tion peatland palaeo ec ol ogy is cru cial for res to ra tion ac tiv i ties, e.g., rewetting and en vi ron men tal man age ment. The palaeohydrological con text (sup ported by other prox ies) of the last 1000 years pro vides a re li able an swer to the ques tion: ‘To rewet or not to rewet?’
