Book excerpt: Producing Christmas trees is big business. Every year, growers in the United States and Canada deliver 30 to 40 million trees to consumers, earning $2 billion in revenue. Growers in Europe produce an additional 110 million trees, earning $1.64 billion. To prepare for future crops, growers also plant up to three times as many trees as they harvest every year. Bringing each crop to market involves years of intensive management. The critical information needed to manage diseases and disorders of all types of conifer trees is provided in Compendium of Conifer Diseases, Second Edition. Written by 102 experts from 18 countries, this new edition presents the modern world of forest pathology. Forests today grow under increasing stress from an ever-growing human population, newly identified and invasive species of pathogens, and a changing climate. And since publication of the first edition of this compendium in 1997, diagnostic tools have evolved considerably, enabling more precise identification of pathogens, greater understanding of population genetics, and better understanding of evolutionary relationships among various species. All of these factors are addressed in the new compendium.
