    The History of Arboriculture


    Arborist, author and historian, Donald F. Blair helps the ISA celebrate its 90th anniversary by sharing some its history. Attitudes about the use of spurs in 1881 or topping in 1907 may surprise you. Some long-forgotten ISA history may also be a surprise. Think the ITCC got its ISA start in 1976 in St. Louis? Come and find out when the first competition actually place. Follow the progress of arborist equipment, practices, safety and training over the past 150 years and gain a better understanding of how the National Shade Tree Conference came to be founded in 1924.
