The principle methods are described by the example of the Tokar delta, which is one of the most important desert locust breeding areas. The upsurge of a new plague in the Tokar delta region was reported by the FAO in January 1993. For detecting
desert locust biotopes multitemporal Landsat Thematic Mapper data and ground truth information are analysed.

Assessment of ecological conditions associated with the 1980/1981 desert locust plague upsurge in West Africa using environmental satellite data

Hurricane-borne African Locusts (Schistocera gregaria) on the Windward Islands in Caribbean hurricanes.

The restoration effects of black locust (Robinia pseudoacacia L) plantation on surface soil properties and carbon sequestration on lower hillslopes in the semi-humid region of Coruh Drainage Basin in Turkey
This study investigated the effects of black locust (Robinia pseudoacacia L.) plantations on surface soil properties in eroded sand loam (SL) soils. Two land use types were selected in the semi-humid region of Artvin, Turkey: a black locust
site. The highest carbon sequestration was measured at a soil depth of 0-10 cm in the BLP site. The black locust plantation (BLP) had a positive impact on surface soil properties and carbon sequestration in eroded lower hillslopes in the semi-humid
region of Coruh Drainage Basin (CDB) in Turkey. The planting of black locust might be useful in soil reclamation projects in this type of eroded sites in semi-humid regions.

The aim of this study was to determine the changes in physical and chemical properties of the soil and plant growth in Pamukcular watershed in Artvin city, 10 years after the plantation of black locust and mixed species (black locust + stone pine
), which were used for rehabilitation of the semi-arid eroded sites in this area. As a result: Although these species didn't showed good growth in the study area black locust plantation (BLP) and mixed species plantation (MSP) had a positive impact

Identification and monitoring of Australian plague locust habitats from Landsat

Effect of spatial variation of tree root characteristics on slope stability. A case study on Black Locust (Robinia pseudoacacia) and Arborvitae (Platycladus orientalis) stands on the Loess Plateau, China

collected from five 37-year-restored lands of abandoned farmland, korshinsk peashrub land, black locust land, Chinese pine land and mixed forest land of amorpha and Chinese pine. It is shown that vegetation recovery decrease rill erodibility but increase

and Potassium (K) contents and enzyme activities in soils were tested and analyzed. The study showed that after 30 years of restoration, nutrients content in the soil of mixed forest of black locust and amorpha increased significantly. However, nutrients content

with the black locust (Robinia pseudoacacia). Reforestation measures induced soil profile development on the gully slopes with distinct humus horizons. The overall effect of the observed changes is an increase in the aggregate stability of these reforested gully
