FIVE quality classes (QCs) defined by the WFD based on ecological

quality ratio (EQR), for Europe’s aquatic ecosystems.

EQRs are defined for each region and ecosystem type on the basis of

the least impacted localities in the area. High-quality sites are those for

which EQR ≈ 1 (similar to reference conditions).

According to the WFD, ecological status the sites in QCs III–V need

to be brought up to acceptable ecological status through

managing and/or restoring (adapted from EC, 2000).

Douro Basin covers mediterranean-type (1-3) and temperate-type

streams with high biodiversity.

Aquatic macroinvertebrates in Douro inhabit a vast array of

environmental conditions, including seasonal intermittency (1-2), cool

fast flowing waters (4), canyons (5), and the large river Douro (6).

The human pressure is present from pristine to highly impacted areas,

mainly due to pasture, intense agriculture and reservoirs.
