The representation of vegetation is important to the orienteer because it affects runnability and it also provides features for map reading.


The basic principle is as follows: - white represents runnable forest.
- yellow represents open areas divided into several categories.

- green represents the density of the forest and undergrowth according to its runnability and is divided into several categories.

Open land
Open land with scattered trees
Rough open land

Forest: easy running
Forest: slow running
Undergrowth: slow running
Forest: difficult to run
Undergrowth: difficult to run
Vegetation: very difficult to run, impassable
