Following is a map of the elm species' and cutivars' locations at the Holbrook elm plantation. The plantation is located in Holbrook next to the Navajo County Fairgrounds, between the Fairgrounds and the Hunt Community Center. Trees are spaced on a 12X12 ft grid of 21 rows and 14 columns. Column and row headings are shown along with tree locations by number. Following the map is a key to the locations of the elm species and cultivars, and a table listing some of the attributes of the elm selections. Note: rows R20 and R21 have only 13 locations each.
