They have been around for over 350 million years and cover almost one-third of the Earth’s land surface. There are more than 80,000 different species (plus numerous cultivars), ranging in size from tiny Arctic Willows, just a few inches high, to Giant Redwoods over 300 feet (100 meters) tall. This book is broken down into conifers, simple broadleaves, and compound broadleaves and then further subdivided by leaf shape. It features the trees that are most commonly found in towns, parks, and gardens, and in the surrounding countryside. Each species is described using clear, concise text and high-quality digital photography and illustrations. Where relevant, information is given on seasonal variations, such as the production of flowers or fruit, changing leaf color, and winter twigs and buds. This book will enable you to identify, understand, and enjoy more than 150 different trees, and will hopefully awaken a lifelong interest. Tony Russell 8 IDENTIFYING TREES Identifying Trees Looking at and identifying trees can be a fascinating and enjoyable pastime. However, unless you know what to look for, it can sometimes be confusing. The following pages aim to provide information to aid accurate identification. Two things to always bear in mind are season and location. These can affect how a tree grows and what it looks like. Season Many trees display seasonal differences. Deciduous trees that are in full leaf in summer will have bare branches in winter. Deciduous leaf color in spring will be very different from the color in the fall. Features like winter twigs and buds, fall leaves, and spring flowers can be helpful in identifying trees in different seasons. FALL LEAVES WINTER TWIG Location The forms of trees can vary by location. For example, trees growing close to each other will be taller and thinner, with fewer low branches than trees growing on their own in an open setting. Trees in exposed or cold locations are unlikely to grow as tall as those in sheltered locations. SHELTERED HILLSIDE EXPOSED MOUNTAINSIDE
