Applied Vegetation Science, Volume 28, Issue 1, January/March 2025.Ericaceous dwarf shrubs are foundation species in the boreal biome, and predicting their response to changes in forest structure is key for comparing the ecosystem effects of different forest management alternatives. We developed predictive models for Calluna vulgaris, Vaccinium myrtillus, and V.
