According to Dale and English (1999),“environmental indicators are tools for different environmental decision-making situations. There are three types of tools aiding environmental decision-making: bits of information, or data; tools to gather data; and tools to organize and analyze data, including models to describe relationships among units of information. They may be quantitative or qualitative”. According to the above, environmental indicators are direct and indirect forms to measure the environmental quality. They define the present state and the tendencies of the environmental capacity to sustain ecological and human health (EPA and SEMARNAP 1997). They are designed to quickly and easily inform decision makers about environmental information dealing with natural conditions. If used for monitoring, over time they may communicate information about ecosystem changes and trends.As management tools, they may provide awareness over developing problems and actions needed.There have been various efforts to design environmental indicators trying to make them analogous and comparable to economic or social indicators. For instance, an exotic species can be a variable to measure vegetation quality that is an environmental health indicator; income is a variable to measure poverty, a socio-economic indicator related to social health.
