| 1 | Ecosystem management in paludified boreal forests:enhancing wood production,biodiversity,and carbon sequestration at the landscape level显示文摘Canada's boreal forest represents an important contributor of the world's wood supply industry. However,maintaining or increasing productivity of the boreal forest may be challenging in areas dominated by forested peatlands. Moreover, sustainable management of these forests must also consider other important aspects of the forest ecosystem such as biodiversity and carbon sequestration. To address these concerns, ecosystem-based management has been implemented in some Canadian jurisdictions, such as in regions where a large portion of the boreal forest is dominated by forested peatlands. The objectives of this paper are(1) to summarize our current understanding of how natural disturbances influence stand dynamics and biodiversity in forested peatlands, and(2) to review the main differences between natural and managed forest stands with respect to soil properties, stand productivity, understory plant communities. We also discuss how even-age management regime succeeds or fails to preserve old forests and how this loss affects both forest structure and habitat diversity at the landscape level.We conclude by showing how, in boreal forested peatlands, forest management could contribute to carbon sequestration and mitigate projected climate change. | Benoit Lafleur Nicole J.Fenton Martin Simard Alain Leduc David Paré Osvaldo Valeria Yves Bergeron | 2018 | Forest Ecosystems2018，5，4： | 1 |
| 2 | Forecasting the development of boreal paludified forests in response to climate change: a case study using Ontario ecosite classification显示文摘Background:Successional paludification,a dynamic process that leads to the formation of peatlands,is influenced by climatic factors and site features such as surficial deposits and soil texture.In boreal regions,projected climate change and corresponding modifications in natural fire regimes are expected to influence the paludification process and forest development.The objective of this study was to forecast the development of boreal paludified forests in northeastern North America in relation to climate change and modifications in the natural fire regime for the period 2011–2100.Methods:A paludification index was built using static(e.g.surficial deposits and soil texture)and dynamic(e.g.moisture regime and soil organic layer thickness)stand scale factors available from forest maps.The index considered the effects of three temperature increase scenarios(i.e.+1°C,+3°C and+6°C)and progressively decreasing fire cycle(from 300 years for 2011–2041,to 200 years for 2071–2100)on peat accumulation rate and soil organic layer(SOL)thickness at the stand level,and paludification at the landscape level.Results:Our index show that in the context where in the absence of fire the landscape continues to paludify,the negative effect of climate change on peat accumulation resulted in little modification to SOL thickness at the stand level,and no change in the paludification level of the study area between 2011 and 2100.However,including decreasing fire cycle to the index resulted in declines in paludified area.Overall,the index predicts a slight to moderate decrease in the area covered by paludified forests in 2100,with slower rates of paludification.Conclusions:Slower paludification rates imply greater forest productivity and a greater potential for forest harvest,but also a gradual loss of open paludified stands,which could impact the carbon balance in paludified landscapes.Nonetheless,as the thick Sphagnum layer typical of paludified forests may protect soil organic layer from drought and deep burns,a significant proportion of the territory has high potential to remain a carbon sink. | Benoit Lafleur Nicole J Fenton Yves Bergeron | 2015 | Forest Ecosystems2015，2，1： | 0 |
