For the first time, a synthesis on the research work done in Europe on all Bark And Wood Boring Insects In Living Trees (BAWBILT) is presented. As final product of a four-year research project gathering together 100 scientists from 24 countries, the book is the fruit of a real collective synthesis in which all European specialists have participated. It reviews and comments on all the European literature, while considering the biological (trees, insects, associated organisms, and their relationships) and forest management aspects. However, although focused on the European forest, it also compares the available information and interpretations to those concerning similar species in other continents. It ends with propositions of research priorities for Europe. The enclosed CD contains a relational database gathering all the BAWBILT research papers published in Europe during the last 30 years and some important older ones, and a series of colour pictures. The book is directed to all scientists and students concerned with forest entomology and ecology, as well as to forest managers and all scientific public interested in forest biology.
Familiar species, common plants, and natural phenomena are introduced in these beautifully illustrated guides to nature and the outdoors. Printed on laminated, water-resistant paper in a folded format, Pocket NaturalistÂ® Guides are highly durable for use in the field as each title provides a portable reference to a variety of mammals, birds, reptiles, amphibians, fishes, butterflies, and insects. Nature enthusiasts, from the beginner to the seasoned explorer, will relish the abundance of detailed information packed within these handheld guides.
This lightweight, foldable guide fits easily into a pocket or backpack and is perfect for exploring the meadows, lakes, waterfalls, forests, and tundra of the Rocky Mountain National Park. With detailed illustrations of the regional plant life, the guide arranges wildflowers by color for easy identification, making novice explorers feel like professional botanists. A helpful map of the area that highlights visitor and ranger stations throughout the park is included, and the guide was produced in collaboration with the Rocky Mountain Nature Association; part of the proceeds from each sale support the organization's work in public awareness and education.
Valued for their lumber, their shade, and the beauty of their flowers and foliage as well as the nuts that nourish wildlife and humans alike, trees play important economic, ecological, and aesthetic roles in our lives. From honey and black locusts to white and chinkapin oaks to yellow and river birches, Trees in Your Pocket gives us identification and natural history information for about forty prominent deciduous species found in the Upper Midwest states of Minnesota, Wisconsin, Illinois, Iowa, and Missouri. Botanist Tom Rosburg provides diagnostic color photographs of leaves, acorns and other fruits, and bark along with descriptions of leaves, fruits, and measurements of blades. The composition, arrangement, shape, and margin of leaves are most important for tree identification. Fruits can help confirm identification of species with similar leaves. The bark of a tree can be very helpful for identifying some species; as a tree ages, older bark (lower on the tree) can be quite different from younger bark (higher and on branches). In addition to these essential markers, Rosburg gives information about range, habitat--savannas, moist forests, dry slopes, sandy soils, and so on--life-span, and tolerance of shade, fire, drought, and flood. Each state in this region maintains a Big Tree program that honours the largest individual tree of each species. Champion trees are determined by adding together measurements of trunk circumference, height, and canopy spread. Rosburg identifies the trees with the largest diameter and the tallest trees among the champion trees in the Upper Midwest by their county and state. Together his superb photographs and key information make this guide the perfect companion for enjoying the diversity of trees in all kinds of environments.
