A report card is released each year, in early to mid April, providing an assessment of the previous year's health. Health is defined as progress of the six indicators towards established scientifically derived ecological thresholds or goals. A low score therefore means that the region rarely meets the ecological threshold levels. A high score means that the region often meets the threshold levels.
