Book Description
The Dipterocarp forests of South-East Asia constitute a dominant component of the world's tropical forests. As such, they are intertwined with a Pandora's box of problems that have plagued the world for decades; Over- and underdevelopment, poverty, hunger, population growth, exploitation of natural resources, environmental degradation, loss of biodiversity, the debt crisis and, of late, climate change. The world community has responded to the crucial role of these forests and the dangers facing them with funds, and a myriad of programmers, projects, institutions, conferences and networks. Apparently neither a lack of knowledge nor finance constrains the dissipation of sustainable management practices: the fate of the world's Dipterocarp forests will certainly depend on the involvement of scientists from many nations and disciplines, but will perhaps ultimately, rest with local policymakers, forest administrators and line foresters. Unfortunately, these two groups rarely share realms, readings or reasoning: practical foresters, invariably very involved with the challenges of day-to-day forest management in remote, isolated environments, may long remain oblivious to scientific developments. Traditionally though they do find solutions to problems, gain deep insights into forest responses and practical constraints, and sometimes even report in semi-obscure publications, which rarely reach the scientific circuit.The editors of the book, both experienced forest and soil scientists and practical forest managers, have attempted to bridge the gap between the realms of forest science and practice in Dipterocarp ecology, management and utilization.

Book Description
Ecological restoration, although a relatively new endeavour compared to other disciplines, has gained significant momentum during the last decade as accelerating global change becomes more apparent. It is now widely accepted by the scientific community that to avoid further devastating effects of climate change and biodiversity loss, humanity must determinedly move more to protect and restore natural ecosystems. Many restoration efforts of the past have been ad hoc, site and situation-specific and have often failed to achieve desired outcomes, but over the last decade, many countries are allocating increasingly significant amounts of financial investment towards restoration with the goal of achieving more systematic and predictable outcomes. Today, activities related to restoring ecosystems, natural assets and biodiversity are a global focus. This book covers a wide range of topics related to ecological restoration including for grasslands, wetlands, temperate and tropical forests and arid zones. Importantly, it also focuses on ecological restoration in human-disturbed landscapes such as for urban areas, farmlands, mine sites and transport corridors. It highlights the necessity for evidence-based approaches that are both nuanced and complementary with prescriptions for people-based restoration, that is socially inclusive and cognisant of historic and current community sentiment. Ambitious landscape and continental scale targets for ecological restoration have been set across the globe. However, without practical guidelines developed from restoration evaluations from the recent past to follow, future efforts are unlikely to be successful, nor -expected targets met. To that end, this book reviews and highlights a large number and variety of restoration stories from around the world. Most are presented as reader-friendly case studies, that feature innovative and systematic techniques for undertaking species-rich ecological restoration. Together they provide inspiration for current and future professionals and offer unique glimpses into state-of-the-art practice for this critically important discipline

Book Description
Southeast Asian dipterocarp forests are highly diverse tropical forest communities, with the family Dipterocarpaceae alone comprising hundreds of species. Dipterocarps are remarkable in that they exhibit supra-annual mass flowering events, which occur in irregular intervals of two to ten years, normally involving several dipterocarp species and sometimes including many other plant families as well, a phenomenon known as general flowering event. Dipterocarps are a leading species group on 85% of Southeast Asia's forested land base and they are also commercially important, representing a quarter of global consumption of tropical timbers. Southeast Asia's dipterocarp forests are also one of the most threatened tropical ecosystems in the world. Only 16% of the total original forested area remains classified as primary forest in Southeast Asia and less than 6% in the Philippines, which is a focus of this thesis. The overall objective of this thesis is to support and improve reforestation and community forestry initiatives in dipterocarp forests by contributing ecological insight and compiling local community knowledge, and by addressing major impediments to successful forest restoration in Southeast Asia. The first issue is the biology of dipterocarp reproduction that makes it hard to manage natural regeneration as well as reforestation. It is logistically difficult to mobilize resources to collect short lived dipterocarp seed without knowing in advance when flowering will occur. This thesis research investigates what environmental factors drive dipterocarp mass flowering and tests alternative resource accumulation and trigger models to predict mass flowering. Using a variety of candidate predictor variables (precipitation, cloud cover, minimum temperature and El Niño indices) a plausible environmental trigger could not be found (median AUCs around 0.55 indicating near random predictions), while the best resource accumulation model had a median AUC of 0.70, which could be improved to 0.75 when the date of previous flowering was included in the model. Further, the analysis revealed that a simple resource accumulation by individual trees can cause inter- and intraspecific flowering synchronization leading to community-wide general flowering events. The second issue is a lack of knowledge of which dipterocarps and which other native species are suitable for reforestation. Community based forest management programs typically use readily available exotic species that may not be desired by the local communities. Choosing species for reforestation programs or community forestry in species-rich tropical rainforest ecosystems is a complex task. Reforestation objectives, social preferences, and ecological attributes must be balanced to achieve landscape restoration, timber production, or community forestry objectives. In a case study for an upland tropical rainforest in the Philippines, socioeconomic preference in five forest-dependent communities were surveyed. In addition, ecological suitability of tree species for open-field plantations was inferred from growth rates, density and frequency of native tree species in long-term monitoring plots. Notably, ecological suitability indicators and socioeconomic preference ranks were generally negatively correlated, with few species being classified as both ecologically suitable and socioeconomically valuable. The results also highlight that reforestation species must be carefully chosen, and that species-rich tropical rainforests are not an easily renewable natural resource. Secondary and planted forests do not serve socioeconomic needs of forest-dependent communities as do original native forests.

Book Description
In Regreening the Bare Hills: Tropical Forest Restoration in the Asia-Pacific Region, David Lamb explores how reforestation might be carried out both to conserve biological diversity and to improve the livelihoods of the rural poor. While both issues have attracted considerable attention in recent years, this book takes a significant step, by integrating ecological and silvicultural knowledge within the context of the social and economic issues that can determine the success or failure of tropical forest landscape restoration. Describing new approaches to the reforestation of degraded lands in the Asia-Pacific tropics, the book reviews current approaches to reforestation throughout the region, paying particular attention to those which incorporate native species – including in multi-species plantations. It presents case studies from across the Asia-Pacific region and discusses how the silvicultural methods needed to manage these ‘new’ plantations will differ from conventional methods. It also explores how reforestation might be made more attractive to smallholders and how trade-offs between production and conservation are most easily made at a landscape scale. The book concludes with a discussion of how future forest restoration may be affected by some current ecological and socio-economic trends now underway. The book represents a valuable resource for reforestation managers and policy makers wishing to promote these new silvicultural approaches, as well as for conservationists, development experts and researchers with an interest in forest restoration. Combining a theoretical-research perspective with practical aspects of restoration, the book will be equally valuable to practitioners and academics, while the lessons drawn from these discussions will have relevance elsewhere throughout the tropics.

Book Description
This edited volume introduces dynamic approaches to the study of Southeast Asia’s environmental diversity from different disciplinary perspectives at the interface between the natural and social sciences. It brings together research on the region’s environmental resource use and shared ecological challenges in the context of present day globalization to offer insights for possible future directions. The book introduces unique approaches to the study of Southeast Asia’s environmental changes and resource management under the influence of intensifying economic change in the region. It also examines the slow erosion of Southeast Asia’s rich environment and addresses serious issues such as the decrease in biodiversity and tropical forests, and the degradation of peat lands. At the same time, it discusses the social issues that are tied to energy-dependent growth and have intensified over the last two decades. It also analyzes the new roadmaps being created to protect, conserve, and manage the environment. By investigating the many ecological issues surrounding us, the volume brings to light the constant struggles we face while trying to develop a more inclusive and equitable approach to natural resources governance. This volume is relevant for students, academics and researchers who have an interest in the Southeast Asian environment and the way in which we use and interact with it.
