The report of 2016–2017 describes riverside forests of the mid-high basin of Tâmega with alders, ash trees and willows, and birch trees in the smaller courses. It mentions often narrow strips, limited by crops. It is a regional description of that study, which covers Cabeceiras and other municipalities.

The margin, the water and the bottom are connected, but offer different conditions. The salamander-lusitan depends on humid environments and reproduces in the water; the young river mussel lives buried in the bed and needs oxygen. The scheme allows to explore these general relationships without representing a place where all these species have been observed together.
