Ecological Roles and Adaptations

Like many mosses, Scapania heterophylla M.Howe plays a vital role in its ecosystem. It serves as a pioneer species, colonizing bare or disturbed areas and paving the way for other plants to establish themselves. Additionally, this moss acts as a sponge, absorbing and retaining moisture, creating a microhabitat for various invertebrates and microorganisms.
