Abstract
Soil and vegetation development were studied on abandoned mine sites in Ward County, North Dakota. The sites studied were 1, 7, 17, 30, and 45 years old since abandonment; unmined sites were also studied to provide measures of comparison. Species diversity was the highest at unmined sites and lowest at the 1-year-old site; sites 7, 17, 30, and 45 years old had 37, 52, 43, and 68 species, respectively. Stand ordination revealed that site ages were the most important in influencing species diversity and composition. Stand-environmental complex ordinations encompassing 53 variables showed topographic variables to be the most important followed by site ages. Species distributional diagrams are provided to show habitat preferences that may be helpful in formulating species prescriptions for revegetation.
