Report
` This volume can be recommended for its detailed ecological approach to management, and more importantly, for the attitude that it conveys concerning the conservation and active management of semi-natural species-rich plant communities for their own intrinsic value. '
S. Collins in Quarterly Review of Biology, vol. 65, June 1990
