Résumé
Temporary (one season) sprinkler irrigation was investigated as a means of promoting revegetation of arid coal mined lands in southwestern Wyoming. Responses of soil and vegetation attributes to non-irrigation and all combinations of 5 irrigation schedules and 3 irrigation rates were evaluated during both the year of irrigation (1984) and the year following irrigation termination (1985). In 1984, irrigation stimulated greater plant establishment than that under non-irrigation, and differences in plant response among irrigation treatments were apparent. While annual species were stimulated by irrigation of two months or longer, perennial/biennial species also responded positively to these treatments. Most irrigation treatments yielded significantly higher perennial grass biomass production in 1985 than in 1984. Perennial grass and total perennial/biennial cover in 1985 were highest under schedules longer than two months and with rates 2 and 3, while biomass was highest under the season long and spring-early summer schedules at these rates.
