Green Broom Moss
Dicranum viride
Overview
Green Broom Moss (Dicranum viride) is a distinctive bryophyte characterized by its bright green, glossy leaves that form dense cushions or mats on tree bark. This epiphytic moss plays a crucial ecological role in forest ecosystems by providing microhabitat for invertebrates, retaining moisture, and contributing to nutrient cycling in woodland canopies.
Green Broom Moss is declining primarily due to habitat loss and degradation from deforestation, agricultural expansion, and urban development that destroys the old-growth forests it requires. Air pollution and climate change further threaten this species by altering the specific microclimate conditions necessary for its survival on tree bark.
Habitat
Green Broom Moss grows exclusively on the smooth bark of mature deciduous trees, particularly beech, oak, and maple, in humid old-growth and semi-natural forests. It typically colonizes the lower trunk sections where bark pH and moisture conditions are optimal for establishment and growth.
