The success of any policy intervention, change in land use or its management practices needs to be evidenced by measurable indicators of success.
In order to measure environmental quality, its function and services that are provided by the environment, indicators are commonly used. Indicators of ecological or environmental quality are required or desirable for monitoring/reporting and provide the basis for many protection policies and monitoring programmes. Indicators help assess human and natural impacts on the environment and ecosystems, including degradation processes. They also identify the effectiveness (or otherwise) of sustainable land management practices and restoration candidates for indicators, and provide supporting methodological information around sampling or monitoring schemes for these indicators. Indicators need to be sensitive to pressure and able to reflect change in environmental/ecological quality status (the capacity of the system to function) at any given location and time. Here we develop statistical methods by which to identify the appropriate candidates for indicators and provide supporting methodological information around sampling or monitoring schemes for these indicators.
