Model Forests

As part of the Green Plan, introduced by the Federal Government in late 1990, a network of model forests was developed to demonstrate the concept of sustainable forest management in practical terms on a working scale. This annual report describes the competitive site selection process, the forests involved in the project, program milestones, the operation of model forests, and highlights of the project. Financial data is included.

Canada is experiencing an unparalleled crisis involving forests and communities across the country. While municipalities, policy makers, and industry leaders acknowledge common challenges such as an overdependence on US markets, rising energy costs, and lack of diversification, no common set of solutions has been developed and implemented. Ongoing and at times contentious public debate has revealed an appetite and need for a fundamental rethinking of the relationships that link our communities, governments, industrial partners, and forests towards a more sustainable future. The creation of community forests is one path that promises to build resilience in forest communities and ecosystems. This model provides local control over common forest lands in order to activate resource development opportunities, benefits, and social responsibilities. Implementing community forestry in practice has proven to be a complex task, however: there are no road maps or well-developed and widely-tested models for community forestry in Canada. But in settings where community forests have taken hold, there is a rich and growing body of experience to draw on. The contributors to Growing Community Forests include leading researchers, practitioners, Indigenous representatives, government representatives, local advocates, and students who are actively engaged in sharing experiences, resources, and tools of significance to forest resource communities, policy makers and industry.

Understanding the patterns of biodiversity and their relationship with environmental gradients is a key issue in ecological research and conservation in forests. Several environmental factors can influence species distributions in these complex ecosystems. It is therefore important to distinguish the effects of natural factors from the anthropogenic ones (e.g., environmental pollution, climate change, and forest management) by adopting reliable models able to predict future scenarios of species distribution. In the last 20 years, the use of statistical tools, such as Species Distribution Models (SDM) or Ecological Niche Models (ENM), allowed researchers to make great strides in the subject, with hundreds of scientific research works in this field. This book collects several research articles where these methodological approaches are the starting point to deepen the knowledge in many timely and emerging topics in forest ecosystems around the world, from Eurasia to America.

Over the past two decades, the author has developed and refined an extremely useful simulation model of forest growth. The JABOWA model was the first successful application of digital computer simulation to a complex natural ecosystem. Effects of global warming, acid rain, and commercial forest harvesting practices have been analyzed with this model. Offering a fresh perspective on ecological phenomena, Forest Dynamics provides all the information necessary to understand and use the model. Written for students and professionals in forestry and ecology, the book sets the forest model within the broader context of the science of ecology and the ecological issues that confront society in the management of forests. It also explains the theoretical foundations of the model.

The aim of this book is to improve the understanding of forest dynamics and the sustainable management of forest ecosystems. How do tree crowns, trees or entire forest stands respond to thinning in the long term? What effect do tree species mixtures and multi-layering have on the productivity and stability of trees, stands or forest enterprises? How do tree and stand growth respond to stress factors such as climate change or air pollution? Furthermore, in the event that one has acquired knowledge about the effects of thinning, mixture and stress, how can one make that knowledge applicable to decision-making in forestry practice? The experimental designs, analytical methods, general relationships and models for answering questions of this kind are the focus of this book. Given the structures dealt with, which range from plant organs to the tree, stand and enterprise levels, and the processes analysed in a time frame of days or months to decades or even centuries, this book is directed at all readers interested in trees, forest stands and forest ecosystems. This work has been compiled for students, scientists, lecturers, forest planners, forest managers, and consultants.
