BBC News has this report about Keepers of Time: A Statement of Policy for England's Ancient and Native Woodland, a massive English Forestry Commission project to replace non-native trees with native ones. Long ago English forests were depleted for ship building and home construction, and they were replanted with a variety of fast-growing, non-native conifers, including Norway spruce (Picea abies) and North American species of spruce and pine. Now many of these trees and other non-natives are going to be cut down to make way for what officials are hoping is a massive regeneration of native trees. The plan also calls for conversion of plantation lands back to forest.
