This book describes the ecoregions of Saskatchewan, following a hierarchical framework for terrestrial ecosystems in Canada. The introduction reviews ecological land classification and the various interrelated factors that are involved in the development of ecosystems: geology, water, climate, vegetation, soils, wildlife, and human impacts. The main section describes the province within the context of the four ecozones and 11 ecoregions that were identified in the framework. For each ecoregion, the book provides a description of the physical setting, such as geology & climate, as well as the biological features that have developed in response to this physical environment. The impact of human activities on the ecology of the area concludes each of these descriptions. Appendices include lists of animal & plant species found in Saskatchewan and a glossary.

A discussion of the direct and indirect mechanisms by which fire and climate interact to influence carbon cycling in North American boreal forests. The first section summarizes the information needed to understand and manage fires' effects on the ecology of boreal forests and its influence on global climate change issues. Following chapters discuss in detail the role of fire in the ecology of boreal forests, present data sets on fire and the distribution of carbon, and treat the use of satellite imagery in monitoring these regions as well as approaches to modeling the relevant processes.

Boreal Shield Watersheds: Lake Trout Ecosystems in a Changing Environment brings together the work of a renowned international group of scientists who specialize in aquatic science and environmental management. They explore the functioning of Boreal Shield ecosystems, focusing on the lake trout, the classic coldwater species of northern glaciated lakes, using it as an indicator of environmental change and as a model to measure the effectiveness of management actions. This book demonstrates how boreal waters have served as a crucible for decades of environmental research into the impacts of nutrient additions, trace contaminants, acid rain, climate change, sport fishing, invasive species, and watershed disturbances. The text builds on this substantial research legacy and explores our ability to manage human interactions with ecosystems across the vast Boreal Shield ecozone of North America, and with other important ecosystems worldwide. It also provides models and new methods of assessing the risk to and the durability of ecosystems in relation to local, regional, and global human activities. Maps and descriptions of several important long-term monitoring sites and an atlas describing more than 3,000 lake trout lakes in the region are special components of the book.

Leonardo da Vinci, the eminent Renaissance scholar and philosopher said, "water is the driver of nature". Many may have considered it to be an overstatement in the past, but at the beginning of the third millennium, no sane individual would disagree with Leonardo's view. Water is becoming an increasingly scarce resource for most of the world's citizens. The current trends indicate that the overall situation is likely to deteriorate further, at least for the next two decades, unless the water profession eschews its existing "business as usual" practices, which can only allow incremental changes to occur. Somewhat surprisingly, the water profession as a whole neither realised nor appreciated the gravity of the global water situation as late as 1990, even though a few serious scholars have been pointing out the increasing criticality of the situation from around 1982. For example, the seriousness of the crisis was not a major issue, either at the International Conference on W ater and the Environment, which was organised by the UN system in Dublin and also at the UN Conference on Environment and Development at Rio de Janeiro. Held in 1992, both are considered to be important events for the water sector of the past decade. It is now being increasingly recognised that the Dublin Conference was poorly planned and organised, and thus not surprisingly it produced very little, if any, worthwhile and lasting results.
