soil rehabilitation had been effective in improving degraded red soils but the degrees of effectiveness varied. Soil organic carbon was the most sensitive of the 3 major soil nutrients considered with regard to land-cover change during ecological
. These findings are important for land use and ecologicalrehabilitation decision-making such as the selection of a soil rehabilitation pathway and the determination of priority areas for ecologicalrehabilitation.
Based on journal publications and a meta-analysis approach, this paper investigates the effects, and their spatiotemporal variations, of different land covers on red soil rehabilitation in China. Results indicate that all the land covers used in red
rehabilitation. Coniferous and broadleaf mixed forest was detected as the most effective land cover in red soil rehabilitation. Some spatiotemporal trends of land-cover effectiveness on red soil rehabilitation exist in a statistically significant sense

The karst of Southwest China is a typical representative of poverty-stricken region with impoverishment-degradation spiral. To essentially break away from this vicious circle, the local ecology, economy and society should be rehabilitated, and hence

Bed elevation, feature adjustments, and spawning use were monitored at three Chinook salmon spawning habitat rehabilitation sites to measure project longevity in a regulated river, Mokelumme River in California. Of the mechanisms monitored, gravel
deflation was the greatest contributor to volumetric reductions, followed by hydraulic scour. As sites matured, volumetric reductions decreased. While complexity is an extremely important aspect of ecological function, artificial production of highly diverse

This study was carried out at Banthra Research Station (BRS) of the National Botanical Research Institute, Lucknow. The goals were (1) to evaluate the effect of long term (5 decades) rehabilitation of sodic land through cropping system on soil
properties) of rehabilitated sodic land (RSL) were compared with adjacent degraded sodic land (DSL) and non-sodic soil (NSS). Microbial biomass and enzyme activities were negatively correlated with soil sodicity parameters : pH, EC, exchangeable sodium
percentage (ESP) and sodium adsorption ratio (SAR), except alkaline phosphatase activity. Rehabilitation of degraded sodic land through cropping showed 79% (mean gain %) improvement in soil quality. It is concluded that rehabilitation of degraded sodic lands

This paper introduces geoecological mapping as a possible method for the scientific foundation of regional environmental rehabilitation. The main argument of the author is that geoecological mapping can be very well used for the individual

. Data on the physical habitat and on channel morphology were collected on a 600-m-long reach in 1963 (immediately prior to the rehabilitation work), in 1966, and in 1999, to evaluate the adjustments. In the morainic section, most structures are no longer
efficient and the channel is unstable. The success of the rehabilitation is therefore conditioned by the physical context of the river.

This article draws on participant observation and interview fieldwork and socioeconomic scholarship to critically examine the dual processes of making and unmaking lively companion commodities, at ARCAS Wildlife Rehabilitation Center in northern

This paper discusses some of the issues involved in planning mine rehabilitation, in particular the need to assess the future state of the rehabilitated mine site, and presents a geomorphologic perspective on this issue. A number of examples
are drawn from the rehabilitation of uranium mines in the Alligator Rivers Region of the Northern Territory and elsewhere in Australia, and methods of assessing the rehabilitation of uranium mines are described for the Alligator Rivers Region.

The aim of this study was to determine efficient ecological model for the restoration of degraded sodic land. The bulk density, pH, electrical conductivity (EC) and exchangeable sodium percentage (ESP) reduced during restoration under both, pure
plantations as well as mixed forest. Increase in water holding capacity (WHC), organic carbon, soil nutrients, microbial biomass (MB), microbial counts, CO2 flux and enzymatic activities showed significant improvement in the soil quality of rehabilitated sites
. The results showed that afforestation with multiple tree species restored soil properties more efficiently than monoculture plantations, and is a relatively good option for sustainable rehabilitation of sodic lands.
