environmental monitoring and rest or at ion requires efficient access to large amounts of spatial information. the geographic information system (gis) and remotely sensed data are related to both physical and man-mad e features. in order to handle this task, the environmental scienc es section (ess) created the environmental data atlas (eda) that uses spatial keys to link all data sources to a ...

Methods Capture data for 15 diadromous and 15 non-diadromous fish species from 13,369 sites throughout New Zealand were analysed to establish features of their geographic ranges. Statistical models were used to determine the main environmental correlates of species’ distributions, and to establish the environmental conditions preferred by each species. Environmental predictors, chosen for their...

Ecological ranking is a prerequisite to many kinds of environmental decisions. It requires a set of “objects” (e.g., competing sites for species reintroduction, or competing alternatives of environmental management) to be evaluated on the basis of multiple weighted criteria, and then ranked from the best to the worst, or vice versa. The resulting ranking is then used to choose the course of an ...

This study illustrates how remotely-sensed data and GIS can be utilized to allow planners to evaluate the relationship between land use, environmental protection policies, and resource availability. The case study examines St. Tammany Parish in Louisiana which has experienced tremendous population growth and land use change in the past two decades. To date, work has been completed on developing...

Resumen. Millions of hectares of forest are destroyed by fire worldwide each year. In order to prevent this ecological and economic disaster, the efficiency of brushwood clearing operations has been proven. It is especially important around urban areas where human lives and properties are at risk. However in France, even if such operations are imposed by the law, it is not always followed in pr...

Land use planning means managing our land and resources and it focuses on the functions of ecosystems. The main purpose of this study is to determine the places and sites with necessary capabilities for ecotourism, environmental conservation, agricultural activities, range management, forestry, afforestation, aquaculture, city planning and industrial development in the studied area. This resear...
