Studying coral health in St. Thomas. Ecosystem health is a metaphor used to describe the condition of an ecosystem. [1] [2] Ecosystem condition can vary as a result of fire, flooding, drought, extinctions, invasive species, climate change, mining, fishing, farming or logging, chemical spills, and a host of other reasons.
Ecological indicators are used to communicate information about ecosystems and the impact human activity has on ecosystems to groups such as the public or government policy makers. Ecosystems are complex and ecological indicators can help describe them in simpler terms that can be understood and used by non-scientists to make management decisions.

Such assessments, in conjunction with contamination and human health risk assessments, help to evaluate the environmental hazards posed by contaminated sites and to determine remediation requirements. [1] In ecological assessment many abiotic and biotic indicators, reflecting the pluralistic components of ecosystems, are used.
