Ecological parameter: altitude preference

Parameter group: region related parameters

Explanation:
The altitudinal preference of species is classified from high to low altitudinal regions. The classification follows the altitudinal division into eight zones from planar (< 300 m) to nival (> 3100 m) according to Ellenberg (1996).
