ISA offers a variety of educational materials to help arborists improve their arboricultural knowledge. Each week we will feature a product, or group of products that will enhance your arboriculture education. This week, ISA is featuring The Landscape Below Ground IV.

Convened in 2018, an international group of presenters introduced the latest research and management practices related to all aspects of tree root development in urban soils. The papers included in these proceedings contribute to the growing body of knowledge on these topics and represent an important resource for practitioners, managers, and policymakers involved in tree care in cities.

The first Landscape Below Ground in 1993 began as an idea to highlight the Morton Arboretum root and soil research program to a regional audience. The Morton Arboretum established the Landscape Below Ground series of conferences to provide a forum for presentation of the latest research and management practices related to all aspects of tree root development in urban soils.

Over the last 25 years, the Landscape Below Ground has become a premier outlet for the dissemination of research that supports tree care practices, and the impact has been significant. This information will help practitioners, managers, and policy­makers choose, site, plant, and care for healthier, longer-lived trees by focusing on trees’ critical and vulnerable root systems and the soil that surrounds them.

Additionally, for a limited time purchase The Landscape Below Ground III at a discounted price. With the 40 percent discount, The Landscape Below Ground is only $10 for ISA members ($12 for non-members).
