Berthold Public School Arboretum is an arboretum on school grounds in Berthold, North Dakota. The Berthold Public school Arboretum was begun in the 1970s when the then science teacher, Tom Hove, and vocational agriculture teacher, Richard Debertin, combined efforts to make an arboretum on the school grounds. Several grants from outside sources and free materials from other public conservation agencies allowed the addition of about 125 varieties of trees and shrubs to the school grounds. About 100 of those varieties were established. Signs and information are minimal. The best source of information is to look up the retired vocational agriculture teacher who still lives in Berthold. This became a valuable project for students who worked in its establishment and a resource for agriculture students studying horticulture and tree and shrub identification.
