Kānuka dryland shrubland communities in South Island, New Zealand, feature a ground cover primarily composed of mosses, which play a crucial but under-researched role in this threatened ecosystem.
The study explored how moss influences hydrology, nitrogen availability, and interactions with vascular plants, particularly in relation to nutrient runoff from nearby farmland.
Findings indicated that moss layers regulate soil temperature and moisture, affect nitrogen levels, and impact vascular plant growth, but nutrient spillover promotes exotic grass invasion, underscoring the need to consider non-vascular plants and nutrient management in restoration efforts.
