Introduction

Abstract

This book examines urban forests in cities around the world. It will ask questions about the history, composition, structure, and management of trees in urban areas. Data for this book was collected in 33 cities across broad geographical areas known as biomes. The concept of the biome is explained. Previous biome classifications are reviewed and classification involving eleven biomes was developed for the book. Three cities in each biome were chosen for study. Constraints and opportunities imposed on urban forest composition, design, and management by the ecological characteristics of these biomes will be examined. The book will also address the cultural and historical factors that influenced the characteristics of urban forests around the world.
