What Is Forest Landscape Restoration?
نویسنده
چکیده
The extent and distribution of global forests is a matter of considerable concern. The overall rate of deforestation remains high although recent reports suggest it is fi nally beginning to decline (FAO 2011 ) . But this hides regional differences. In temperate regions net forest cover is increasing because of afforestation and natural expansion of forests. By contrast, net forest cover in most tropical regions continues to decline and few of the remaining forests are being managed on a sustainable basis (Asner et al. 2010 ; Foley et al. 2005 ) . This means that more and more tropical countries are changing from being exporters of forest products to being importers. Across the globe most deforestation has been carried out to create agricultural lands but a large proportion of these lands have subsequently been abandoned (Ramankuty and Foley 1999 ) . In upland mainland Southeast Asia, for example, Fox and Vogler ( 2005 ) note that as much as 49% of these new agricultural lands are reported to have been subsequently abandoned and become shrub, brush or other forms of secondary forest. At the same time the Millennium Ecosystem Assessment found 60% of the world’s

OP IN ION ART ICLE Forest Landscape Restoration: increasing the positive impacts of forest restoration or simply the area under tree cover?
Restoring forest landscapes is critical in the face of continued global forest loss and degradation. In this article, we explore some challenges underlying the delivery of global commitments to restore forest landscapes. We propose that three fundamental questions need to be resolved upfront for the effective implementation of Forest Landscape Restoration and related commitments: (1) What socia...
متن کاملCultural drivers of reforestation in tropical forest groves of the Western Ghats of India
Sacred forest groves in the Western Ghats of India are small fragments of tropical forest that have received protection due to religious beliefs and cultural practices. These forest fragments are an example of community-based conservation and they serve as refugia for many forest-dwelling species in otherwise highly anthropogenic tropical forest-agriculture landscapes of the Indian Western Ghat...
متن کاملLandscape Modeling for Forest Restoration: Concepts and Applications
Abstract-Restoration planning, evaluation, and implementation are of paramount importance in many areas where the magnitude of the abiotic and biotic disturbance agents has altered the resources and conditions of forest landscapes. However, the effect of restoration practices is difficult to measure, and in many areas the restoration goals are yet less clear. Landscape modeling provides useful ...
متن کاملA global meta-analysis on the ecological drivers of forest restoration success
Two billion ha have been identified globally for forest restoration. Our meta-analysis encompassing 221 study landscapes worldwide reveals forest restoration enhances biodiversity by 15-84% and vegetation structure by 36-77%, compared with degraded ecosystems. For the first time, we identify the main ecological drivers of forest restoration success (defined as a return to a reference condition,...
متن کاملSwanson WHAT CAN HISTORY TELL US ABOUT FOREST LANDSCAPE DYNAMICS ?
Historical forest landscape dynamics include consideration of spatial and temporal distributions of forest conditions over recent history and also historical disturbance regimes. Understanding of historical landscape dynamics in these senses is relevant to planning future management of federal forest lands on both policy and ecological grounds. Although some particular elements of our policy fr...
متن کاملWhen is a forest a forest? Forest concepts and definitions in the era of forest and landscape restoration
We present a historical overview of forest concepts and definitions, linking these changes with distinct perspectives and management objectives. Policies dealing with a broad range of forest issues are often based on definitions created for the purpose of assessing global forest stocks, which do not distinguish between natural and planted forests or reforests, and which have not proved useful i...
