broom moss with upright stems like a tiny green forest

Size
Height: 3–8 cm
Lifespan
3–7 years
Diet
Photosynthetic. Absorbs water and dissolved minerals directly through leaf surfaces. Requires consistent moisture and acidic soil.
Habitat
Grows on the forest floor, on rotting logs, and on the banks of streams throughout New Zealand. A creature of the open forest, the sunny clearing, the places where the light filters through and the ground is damp. Forms upright, tufted colonies of dark green leaves that lean in one direction.
Range
Found throughout the North and South Islands on forest floor, rotting logs, and stream banks. Most common in open, sunny locations with consistent moisture. Also found in temperate and cold regions worldwide.
Endemism
Native
Main Threats
None significant. This species is common and widespread in open, damp habitats. Localised threats include habitat loss from land development, drainage of wetlands, and trampling by hikers.
Population
Not Threatened. Broom moss is common in forests throughout New Zealand, particularly in open, sunny locations on the forest floor and on rotting logs. It is a widespread species found in temperate regions around the world.
Conservation Status
Not Threatened
Human Risk
harmless
Handling Note
common moss, safe to handle
Conservation Note
Native moss; not assessed by NZTCS as bryophytes are generally outside the scope of current threat classifications.
Te Ao Māori
No recorded Māori name distinguishes the broom moss from other mosses. Mosses were generally called pūkohu (mosses and lichens) or rimu (a general term for small, low-growing plants). The leaning, windswept tufts on the forest floor would have been noticed. They looked like a crowd of people leaning in to hear a secret. But no distinct name survives. The broom moss was sometimes used as a bedding material. The soft, tufted mats were gathered and dried. Then used to line sleeping places.
It leans in one direction. Broom moss looks like it is listening. It has stems that are upright. Reaching 3 to 8 centimetres in height. With leaves that are long, narrow, and pointed. The leaves are dark green and glossy. With a distinctive toothed margin near the tip. But the most striking feature is the way the leaves lean. All in the same direction. Like a field of grass bent by the wind. Or a crowd of people turning their heads toward a sound. It is the moss of the leaning tuft. The one that looks like it has heard something interesting. What makes it special is the directionality. Broom moss is one of the few mosses that consistently leans in one direction. The leaves are not arranged in a spiral around the stem. They are arranged in a fan. All facing the same way. This gives the moss a distinctive, windswept appearance. As if it has been shaped by a prevailing wind. In fact, the leaning may be an adaptation to light. The leaves orienting themselves to capture the maximum amount of sunlight. It is the moss of the sunny clearing. The one that reaches for the light. The one that looks like it is straining to hear a secret. The leaves are long, narrow, and sharply pointed. With a toothed margin near the tip. The leaf base is broad and sheathing. Wrapping around the stem. The leaves are glossy and dark green. Giving the moss a rich, vibrant appearance. Under a hand lens, the teeth on the leaf margin are visible. Tiny sawtooth edges that catch the light. Biologically, the broom moss reproduces by spores. Released from capsules at the tips of tall, reddish-brown stalks. The capsules are curved and asymmetrical. Like little urns perched on slender stems. To find broom moss is to find the leaning tufts on the forest floor. It is dark green, glossy, and leaning. A crowd of tiny plants all listening to the same sound. You can see the way the leaves bend. The way they point. It is the moss of the leaning tuft. The one that looks like it has heard something and turned its head to listen. The one that proves that even the smallest plants can have a sense of direction.
