        Terms in the glossary are arranged alphabetically. In some instances, terms within a family (for example, thinning) are grouped together to make it easier for the reader to compare them. In such cases, each member of a family (for example, precommercial thinning) is also listed alphabetically, but the reader is referred to the family name.

        Each term appears in boldface letters and is followed by its equivalent term in French in brackets. Terms used as both nouns and verbs are identified as such by n and v, respectively. The generic of the French equivalent term is offered in this edition, and refers to the dominant noun when the equivalent is not a single word.

        The number in parentheses following a term refers to the source of the definition. These sources are listed below. In many cases, definitions taken from such sources have been paraphrased and/or edited to agree with house style. This publication is the source of those definitions not followed by numbers in parentheses.
