Common trees of Pennsylvania

A practical field guide presents concise identification keys, diagrams and plates to help recognize fifty native and four introduced tree species in Pennsylvania by leaves, twigs, bark, buds, fruit and growth habit. It opens with an accessible foreword on trees' ecological and human uses, explains technical terms, illustrates leaf types and arrangements, and outlines tree structure and functions. Each species entry summarizes distinctive features, seasonal notes on fruiting and size classes, and timber or ornamental value, supported by sketches and measurement cues for seasonal identification.
