Aluskasvilajeja
Aluskasvilajeja is a Finnish ecological term used to describe the understory plant species that occupy the layer of vegetation beneath the forest canopy. It is a functional category rather than a formal taxonomic rank, encompassing a broad range of life forms that are adapted to shade, low light, and in many cases higher humidity. The exact composition of aluskasvilajeja varies by forest type, region, soil moisture, and disturbance history, but common groups include shade-tolerant herbs, ferns, mosses, and dwarf shrubs.
