| In the U.S., state reclamation laws call for revegetation, area cleanup and protection of surface and groundwater. |
|
| She said the continued revegetation efforts of community groups had prompted Active Community Environmentalist members to launch the nursery. |
|
| Officials have targeted 750 acres for revegetation each year for the next half-century. |
|
| However, literature on North Slope wetland restoration suggests that objectives of revegetation are vague. |
|
| Or perhaps to set up revegetation programs, there's no reason why you couldn't use a metalliferous plant material as your mulch or your compost. |
|
| From safaris to ski tours to revegetation projects, Sierra Club Outings has a trip for you. |
|
| Next year we will have soil and revegetation materials on it, and by 2020 it'll look very much like the landscape surrounding the mine itself. |
|
| If there was any significant recovery, it probably resulted from spontaneous regrowth rather than artificial revegetation and artificial erosion control. |
|
| After spreading, the ground surface should be roughened to provide micro-sites suitable for revegetation. |
|
| Take all the necessary steps to control bank erosion through stabilization and revegetation techniques. |
|
| Closure will focus on dismantling and removing all buildings and equipment, resloping and revegetation. |
|
| Slope grading and revegetation will, in most cases, serve to control erosion in the pit. |
|
| Only minor scarification, grading, and revegetation will be required to return trails to their natural topography and to provide proper drainage. |
|
| Thus, evolutionary dynamics that effect plants species, such as revegetation, succession and fire, are relevant to this theme. |
|
| Mining techniques take environmental needs into account: tailings stored in stabilised heaps, control of water run-off and revegetation. |
|
| This includes studies into every aspect of improving oil sands reclamation, including revegetation, watershed management and the development of better reclamation materials. |
|
| Images from an airborne sensor were collected in the summers of 1996, 1998 and 1999 to illustrate progress in revegetation over tailings areas at the site. |
|
| Sump morphology or revegetation of the sump can promote the accumulation of snowdrifts, which insulate the ground and warm permafrost temperatures. |
|
| Based on the results, Boudreau and his colleagues would not recommend beach pea be used in revegetation efforts in areas with similar soil. |
|
| The 1997 White Paper on the Conservation and Sustainable Use of South Africa's Biodiversity also supports provisions for the use of local, indigenous species in rehabilitation and revegetation schemes. |
|
|
|
| For example, the department is developing improved science and technology for the safe and effective stabilization, disposal and revegetation of mine sludge to minimize and prevent metal leaching and mobilization. |
|
| They also have worked together to enhance trout habitat through riparian revegetation, livestock exclosures, and non-native fish removal. |
|
| In response to a follow-up question from the Commission on this revegetation plan, COGEMA noted that no woody species would be planted because they would not be able to compete with the initially dominant grasses and legumes. |
|
| Moore said the rangers' work had achieved significant revegetation and they were beginning to see the return of threatened species, but the social impact had been hugely important. |
|
| Active revegetation, such as seeding, can be done during the fall so that the winter snow layer can provide plants with a water source the following spring. |
|
| We have forwarded a revegetation manual and a wetlands manual. |
