This book is divided into two sections, Pictorial Keys and Master Pages. The Keys section provides an easy visual comparison of details to narrow the identification of a tree to one of a small group--the family or genus. The Master Pages then further narrow the differences within a family group to determine the exact species of the tree. More than 1500 photographs, many shown in actual size, are used to provide details such as, leaves, fruit, etc.

A new method for the practical identification and recognition of trees -- and an important supplement to existing botanical methods. The book is in two parts: Pictorial Keys and Master Pages. The Keys are designed for easy visual comparison of details which look alike, narrowing the identification of a tree to one of a small group -- the family or genus. Then, in the Master Pages, the species of the tree is determined, with similar details placed together to highlight differences within the family group, thus eliminating all other possibilities. The details of the Oak trees on this plate are an example of the system. All of the more than 1500 photographs were made specifically for use in this book and were taken either in the field or of carefully collected specimens. Where possible, details such as leaves, fruit, etc., appear in actual size, or in the same scale.

A system for regenerating land, storing carbon, and creating climate resilience The concept of silvopasture challenges our notions of both modern agriculture and land use. For centuries, European settlers of North America have engaged in practices that separate the field from the forest, and even the food from the animal. Silvopasture systems integrate trees, animals, and forages in a whole-system approach that offers a number of benefits to the farmer and the environment. Such a system not only offers the promise of ecological regeneration of the land, but also an economical livelihood and even the ability to farm extensively while buffering the effects of a changing climate: increased rainfall, longer droughts, and more intense storm events. Silvopasture, however, involves more than just allowing animals into the woodlot. It is intentional, steeped in careful observation skills and flexible to the dynamics of such a complex ecology. It requires a farmer who understands grassland ecology, forestry, and animal husbandry. The farmer needn't be an expert in all of these disciplines, but familiar enough with them to make decisions on a wide variety of time scales. A silvopasture system will inevitably look different from year to year, and careful design coupled with creativity and visioning for the future are all part of the equation. In this book, farmer Steve Gabriel offers examples of diverse current systems that include: A black locust plantation for fence posts coupled with summer grazing pastures for cattle in central New York; Oxen and pigs used to clear forested land in New Hampshire to create space for new market gardens and orchards; Turkeys used for controlling pests and fertilization on a cider orchard and asparagus farm in New York; and Sheep that graze the understory of hybrid chestnut and hickory trees at a nut nursery in Minnesota. All of these examples share common goals, components, and philosophies. The systems may take several years to establish, but the long-term benefits include healthier animals and soils, greater yields, and the capacity to sequester atmospheric carbon better than forests or grasslands alone. For all these reasons and more, Silvopasture offers farmers an innovative and ecological alternative to conventional grazing practice.
