North Dakota has roughly 20 arboreta, though many of them are in decline. NDSU Extension developed an arboretum improvement project that included field visits, site inventories, and educational programming. North Dakota’s arboreta are a diverse group with over 70 genera and more than 500 tree and shrub species represented. Soil Conservation District (SCD) arboreta have an average of 31 species per arboretum while non-SCD arboreta average about 70. Labeling methods and accuracy, condition, and maintenance varied greatly. We conducted four educational workshops for arboretum managers, but attendance was relatively low: only 21 individuals attended. Attendees include SCD employees, Extension agents, and arboretum managers. A follow-up evaluation indicated that all respondents found the labeling infographic or the arboreta locations map helpful. Roughly 62% of arboretum managers gained knowledge and skills that align with the project’s objectives. However, a change in behavior amongst many arboretum managers is yet to be seen.
