For centuries, Britain has been reforesting its depleted woods with conifer species native to places like North America and Australia. All that is about to change. The Guardian is reporting that the Forestry Commission has begun a century-long campaign to rid British forests of many of their conifer trees, and to encourage the growth of native broadleaf tree species, including ash (Fraxinus spp.), beech (Fagus spp.) and maple (Acer spp.). Several of the North American conifers, such as the noble fir (Abies procera) and the lodgepole pine (Pinus contorta), have escaped from cultivation in Britain, as well as in other parts of Europe to which they've been introduced.
