Written by specialists in the field, the Collections of CEU Articles feature compilations of CEU articles published in Arborist News. Each Collection focuses on a different theme selected to help increase your knowledge and provide a better understanding of the subject matter for arborists. 

The topics of available compilations offered include: Tree Science, Urban Forestry, Tree Biology, Plant Health Care (Volumes 1 and 2), Tree Diagnosis and Treatment, Tree Maintenance, Tree Selection and Planting, Trees and Their Environment, Safe Work Practices, and Tree Risk Assessment.  

The ten collections that make up Volume 1 can also be purchased individually or as a set—Collection of All CEU Articles-Online Version. 

*You may earn CEUs for the quizzes in these collections of articles even if you previously completed the Arborist News quiz from the same article. However, the CEUs for these collections of articles may be earned only once during the lifetime of your certification.
