This book describes the results of the Covered Catchment Project at Gardsjon in Sweden. This is a major project in which a large roof has been erected under a forest canopy to shelter the soil from acid rain in that area, which is replaced with clean rain to see whether the soil and water recovers from acidification, and if so, how quickly. The project has been underway for over five years and is producing interesting results which have important implications for emission control policy.
