Environmental and Qualitative Indicators

Few environmental and qualitative indicators exist, and certainly very few are examined on a regional or national scale. Potential indicators within this category include tree health and mortality, water quality measures, wildlife population and intrusion indicators, and public metrics. Many of these indicators would form the basis for an improved drought monitoring system that places far greater reliance on impacts to assess drought status and to corroborate physical data, an attribute of drought monitoring that is currently almost nonexistent in the United States and in most countries. The importance of these indicators cannot be overlooked as potential drought monitoring tools.
