Cones from 275 Juniperus trees were collected throughout the Great Plains from 1973 to 1976 and then sown and grown in a nursery in Nebraska in August of 1977. In 1980 the 2-year old seedlings were distributed to plantations across the Great Plains. This dataset contains the height of the surviving trees after 5 years (measured in 1984), in 6 different plantations that were determined to be the best representation of environmental conditions in the Great Plains. The plantations were located in Towner and Mandan, North Dakota; Plattsmouth and Hastings Nebraska; Colby, Kansas; and Big Spring, Texas. With the exception of the Texas plantation, the datasets also contain the following information for each tree: crown spread (from north to south, and then from east to west), number of terminals, tree vigor, sex of flower, abundance of flowering, branch angle, foliage density, and presence of galls from cedar apple rust disease. The two Nebraska datasets also contain height measurements taken before and after the 5 year heights in 1984, and a winter burn rating recorded in 1984.

Juniperus seeds were collected from stands throughout the Great Plains of North America, which is a vast region encompassing nearly one-fourth of the land mass of the United States. It extends uninterrupted through the central part of the continent from t
