Habitat type 91E0 in Croatia extends to approximately 80,000 ha. It contains 16 types according to the National habitat classification of Croatia (NHC). They are based on phytosociological principles and are aligned with the level of association. They are:
E.1. Riparian alluvial willow forests (Salicion albae Soó 1930), poplar (Populion albae Br.-Bl. 1931) and white alder forests (Alnion incanae Pawl. in Pawl. et al. 1928)
Riparian alluvial willow and poplar forests (Salicion albae, Populion albae)

The article contains a description, area of distribution in Croatia, and diagnostic indicators for each type. For each type related types are listed, the corresponding code according to EUNIS-classification, and literature in which is described in more detail.
This article has practical importance because it helps in the identification and mapping of forest habitat types, and these tasks are currently being implemented in the Croatian forestry.
