Following the conference presentations, a researcher summit was held at the Morton Arboretum to assess the current state of root and soil research and identify future research needs. Seven distinct subgroups were identified within the broader topic of urban soils and root systems. They include: Nursery Production and Planting; Structural Root Depth; Construction and Infrastructure; Tree Stability; Root Growth and Development; Soils (physical, chemical, and biological properties); and Soils Management and Root Responses. Overall research priorities developed were distributed across all seven of these areas (see Top 10 Research Priorities, page 391). Throughout each of these subgroups, several overarching themes emerged. They include a need for more collaboration, the establishment of long-term studies, translation of existing research into many languages, and a greater understanding of the complexity of the many issues that span all segments of the green industry. To maximize the impact of root and soil research on the industry, results and conclusions must be synthesized and distributed in a means suitable for the intended audience. The list of potential audiences include city officials, consumers, tree care and other green industry professionals, urban planners, civil engineers, and landscape architects. Educating consumers and industry groups that professionalism and quality have value is a key step in promoting tree health.
