Draw a river inside
Middle and upper Tâmega basin · landscape studied in 2016–2017
The river has a woodland too
The 2016–2017 report describes riverside woodland in the middle and upper Tâmega basin with alders, ashes and willows, and birches along smaller waterways. It notes that these strips are often narrow, constrained by cultivated land. This is the regional description from that study, which covers Cabeceiras and other municipalities. Bank, water and riverbed are connected but offer different conditions. The gold-striped salamander depends on damp environments and reproduces in water; young freshwater mussels live buried in the riverbed and need oxygen. The diagram explores these general relationships without representing a place where all these species have been observed together.
Vamos experimentar?
- Draws a bank, water and the bottom of the river.
- Opens each area of the scheme and chooses a relationship to represent in the drawing.
- Use arrow keys to connect environments; a species may depend on more than one zone.
An activity with paper and pencil, from the scheme. It is not necessary to enter the water or collect organisms.
