The literature guides environmental planning and, specifically, how to use ecological rehabilitation projects to achieve long-term
planning goals and landscape-scale environmental sustainability. There is, however, a perceived gap between principles in
the literature and the use of them by practitioners involved in smaller-scale ecological rehabilitation projects. Using interviews
with practitioners involved in 11 projects within the Regional Municipality of Waterloo, Ontario, Canada, we tested whether
practitioners used five principles for effective planning and implementation of ecological rehabilitation that we derived
from the literature. These five principles were: establishing political and ecological context, using ecologically appropriate
objectives and practices, using comparative multidisciplinary and cross-scale approaches, using adaptive planning and implementation,
and establishing good communication within and external to projects. Few projects followed all five principles, and practitioners
indicated that they used three more project-specific principles: obtaining political/social support, promoting projects and
changing attitudes about projects, and securing sufficient and persistent funding to maintain a project's life. While the
literature emphasizes that ecological rehabilitation is only effective if projects are coordinated on a watershed basis, most
practitioners focused solely on the goals of their specific project. The gap between literature and practice may arise because
most practitioners are new to the field of ecological rehabilitation and still are focused on the methods involved. Time pressures
force practitioners to obviate the literature and get projects started quickly, lest support evaporate. Complicating these
difficulties is decreased support from federal and provincial governments for large-scale environmental planning. It is unclear
whether ecological rehabilitation projects in Waterloo Region (at least) will ever become effective at promoting landscape-scale
ecological goals or remain smaller-scale stop-gaps. 相似文献

The CSM is the first French waste disposal facility for radioactive waste. Waste material is buried several meters deep and
protected by a multi-layer cover, and equipped with a drainage system. On the surface, the plant cover is a grassland vegetation
type. A scientific assessment has been carried out by the Géophen laboratory, University of Caen, in order to better characterize
the plant cover (ecological groups and associated soils) and to observe its medium and long term evolution. Field assessments
made on 10 plots were complemented by laboratory analyses carried out over a period of 1 year. The results indicate scenarios
and alternative solutions which could arise, in order to passively ensure the long-term safety of the waste disposal system.
Several proposals for a blanket solution are currently being studied and discussed, under the auspices of international research
institutions in order to determine the most appropriate materials for the storage conditions. One proposal is an increased
thickness of these materials associated with a geotechnical barrier since it is well adapted to the forest plants which are
likely to colonize the site. The current experiments that are carried out will allow to select the best option and could provide
feedback for other waste disposal facility sites already being operated in France (CSFMA waste disposal facility, Aube district)
or in other countries. 相似文献
