Arboriculture & Urban Forestry Arboriculture & Urban Forestry is a refereed, international journal that publishes high-quality research results on scientific and cultural aspects of the selection, establishment, culture, and maintenance of individual trees, as well as on the structure, function, and manage- ment of forests in and around human settlements. The journal welcomes reports of original research, reviews, and analy- ses that advance the professions of arboriculture and urban forestry. Subjects appropriate for submission include: tree biology, entomology, pathology, horticulture, biomechanics, risk management, soil science, urban forest benefits and management, and utility forestry. To be considered for publication, manuscripts must make a significant contri- bution to the advancement of knowledge and practice of arboriculture and urban forestry and have broad applicability and interest to an international audience. Contributions will be considered in the following categories: (1) Original Research: Original fundamental or applied research that contributes to the scientific foundations supporting the disciplines of arboriculture and urban forestry; (2) Reviews: Literature reviews or syntheses of previous work to identify trends, designate areas for new work, and/or compare competing theories; (3) Empirical Analyses: Appropriate for analysis of procedures, equipment, or management systems that will lead to the improvement of best management practices; (4) Features: History and current status of topics of interest to practicing arborists and urban foresters, with emphasis on application of research to practice; (5) Short Communications: Appropriate for original research investigations that report preliminary or novel results on limited data sets. They are subject to the same review policies as research articles; (6) Commentaries: These short opinion pieces are evaluated for con- tent by the Editors and may be sent to outside reviewers.
