The International Society of Arboriculture and The Morton Arboretum present the Landscape Below Ground IV International Workshop on Tree Root Development in Urban Soils, to be held in Lisle/Naperville, Illinois, USA, October 15-17, 2018.  The conference will provide a forum for scientists and professionals in academia, industry and government throughout the world to present their latest research findings and management practices in all aspects of tree root development in urban soils.  Like the three preceding conferences, it is anticipated that this event will foster closer cooperation between disciplines and geographic areas, and inform managers and policy makers about current research efforts, and have a significant impact on arboricultural practices.

The program committee is soliciting a call for presentations and posters for the conference.  Presentations will be 30 minutes in length.  Complimentary conference registration and partial travel support will be available for lead oral presentation presenters.  Proposals will be evaluated based on overall quality, appropriateness and timeliness of topic, well-defined focus, and practical applications of material.  Topics of interest include, but are not limited to:

  • Tree root development and management
  • Managing urban soil environments (physical properties, nutrient availability, biological processes)
  • Tree root system biomechanics
  • Root structure and stability
  • Tree production, planting and establishment
  • Infrastructure conflicts and solutions
  • Construction damage and preservation
  • Planting site design

Submit Abstract


The committee has extended the POSTER deadline (until poster selection is full).

When Joy Morton established The Morton Arboretum in 1922, he envisioned a “great outdoor museum” of trees. Today, our living collections inspire visitors to appreciate, learn about, plant, and protect trees. The Arboretum champions the world's trees through plant collections, science and conservation, education, and outreach.

The Morton Arboretum's 1,700 acres hold more than 222,000 live plants representing nearly 4,300 taxa from around the world. Situated on the rolling Valparaiso moraine and bisected by the East Branch of the DuPage River, the Arboretum is planned and planted to nurture and display trees and shrubs in environments conducive to their growth.

The Arboretum conducts leading scientific research on tree health and tree improvement, collects and displays trees for study and enjoyment on the grounds, offers educational programming for adults and children, and presents nature-related activities year-round for people of all ages and interests.

Also on the grounds are the Visitor Center with The Arboretum Store and Ginkgo Restaurant and Café, four-acre Children’s Garden, one-acre Maze Garden, Sterling Morton Library, Plant Clinic, nine miles of roads, and 16 miles of trails.
