stairstep moss

Hylocomium splendens

Stairstep moss is a soft, green plant that grows in layers, looking like little steps. It loves to live in cool, shady places and can often be found on forest floors.

Habitat: Forests

Appearance

The stairstep moss has a distinctive tiered growth pattern, resembling miniature staircases with new growth arising from the middle of previous year's shoots. It typically displays rich green fronds, often with reddish stems, creating a lush, carpet-like appearance on the forest floor.

Interesting facts

Each 'step' represents a new year of growth, just like rings on a tree!

Scientists can tell a forest's age by counting the 'steps' on older stairstep moss!

This moss can live for many decades, slowly building up its layered form.

Tiny critters like tardigrades often hide inside its dense, moist cushions.

Special abilities

Stairstep moss can absorb and hold many times its weight in water, which helps it survive dry periods.

Stairstep moss grows new segments annually on top of old ones, helping it slowly spread over obstacles.

Stairstep moss forms dense mats, which helps protect the soil from erosion caused by rain and wind.
