Once the reference condition has been established, any site suspected of being impacted can be assessed by comparison to the reference sites, and its status determined. The Reference Condition database, once formed, can be used repeatedly.978-1-4613-4705-7978-1-4419-8885-0

s the Reference Condition Approach. This is a significant advancement in biomonitoring because it solves the problem of trying to locate nearby control or reference sites when studying an ecosystem that may be degraded, a problem that bedevils traditional approaches. Rather than using upstream refer

Variation in the Reference Condition, rather than being a problem, is a characteristic to be “captured” for the region being studied. We must measured and characterize it before we can assess a test site.
