Abstract
Trickle irrigation, during establishment, increased survival two fold for seven species of shrubs and trees planted on coal mine spoil in the semiarid area of northeastern Wyoming, USA. Increased survival of irrigated plants persisted for five years after initiation of this study, which included two growing and winter seasons after cessation of irrigation. Species included green ash (
Fraxinus pennsylvanica), Russian olive (
Elaeagnus angustifolia), silver buffaloberry (
Shepherdia argentea), Siberian peashrub (
Caragana arborescens), American plum (
Prunus Americana), ponderosa pine (
Pinus ponderosa) and Rocky Mountain juniper (
Juniperus scopulorum).
