Authoritative, encyclopedic, lavishly illustrated guide to the trees of the state and region—from the Morris Arboretum, the official arboretum of the Commonwealth of Pennsylvania.

This is a guide to finding tree-roosts. It is the result of the collaborative efforts of professional surveyors and amateur naturalists across Europe as part of the Bat Tree Habitat Key project, and represents a combination of firsts: It is the first time legislation and planning policy have been reviewed and put to practical use to define an analysis framework with clearly identifiable thresholds for action. Yet, despite its efficacy in a professional context, it is also the first time a guide has been produced that is equally effective in achieving its objective for amateurs. It is the first time such a method has been evidence-supported throughout, with summary reviews of each aspect of the roosting ecology of the individual 14 tree-roosting species, with illustrative photographs and data to which the reader has open access. It is the first time a repeatable analysis framework has been defined against which the surveyor may compare their results at every stage, from the desk-study, through ground-truthing, survey and analysis, thereby ensuring nothing is overlooked and that every result can be objectively compared. The survey and analysis framework itself is ground-breaking in that it may readily be adapted for any taxa; from moths, through amphibians, reptiles, birds and all other mammals. Used diligently, these methods will reward disproportionately and imbue the reader with renewed confidence as they quickly progress from beginner to competency. Thus, this book is for everyone who has ever wanted to find a tree-roost, or to safeguard against inadvertently damaging one.

Invasions of non-native plants into forests of the Southern United States continue to go unchecked and only partially un-monitored. These infestations increasingly erode forest productivity, hindering forest use and management activities, and degrading diversity and wildlife habitat. Often called non-native, exotic, non-indigenous, alien, or noxious weeds, they occur as trees, shrubs, vines, grasses, ferns, and forbs. This guide provides information on accurate identification of the 56 non-native plants and groups that are currently invading the forests of the 13 Southern States. In additin, it lists other non-native plants of growing concern. Illustrations. This is a print on demand edition of an important, hard-to-find publication.

The definitive field guide to the trees of North America, featuring maps, detailed illustrations, and information on more than 600 species of trees, from the preeminent, bestselling author and illustrator “A beautiful, masterful, and much-needed work that will henceforth be our guide to the North American trees.”—Edward O. Wilson The Sibley Guide to Trees is an astonishingly elegant guide to a complex subject. It condenses a huge amount of information about tree identification—more than has ever been collected in a single book—into a logical, accessible, easy-to-use format. With more than 4,100 meticulous, exquisitely detailed paintings, the Guide highlights the often subtle similarities and distinctions between more than 600 tree species—native trees as well as many introduced species. More than 500 maps show the complete range, both natural and cultivated, for nearly all species. No other guide has ever made field identification so clear. Highlighted features include: • leaves (including multiple leaf shapes and fall leaf color) • bark • needles • cones • flowers • fruit • twigs • silhouettes Trees are arranged taxonomically, with all related species grouped together. By focusing on the fundamental characteristics of, for example, oaks or chestnuts or hickories, the Guide helps the user recognize these basic species groups the same way birders recognize thrushes, warblers, or sparrows. In addition, there are essays on taxonomy, on the cultivation of trees, and on conservation issues, reflecting Sibley’s deep concern with habitat preservation and environmental health. An important contribution to our understanding of the natural world, The Sibley Guide to Trees is a necessity for every tree lover, traveler, and naturalist.
