lives on the stable bark of old trees

Size
Width: 2–4 cm
Lifespan
5–10 years
Diet
Grows on bark of old trees, rocks, and rotting logs in damp, shaded forests. Requires high humidity, stable bark surfaces, and clean air. Sensitive to habitat disturbance, drought, and air pollution.
Habitat
Grows on the bark of trees, on rocks, and on rotting logs in damp, shaded forests throughout New Zealand. A creature of the old forest, the stable bark, the places where the tree has been standing for centuries and the air is always damp.
Range
Found in the South Island's beech forests and the North Island's western ranges. Most common in old-growth forests with high rainfall and stable humidity. Endemic to New Zealand. Populations declining due to habitat disturbance, drought, and forest fragmentation.
Endemism
Endemic
Main Threats
Habitat loss from forest clearance and fragmentation is the primary threat. Also threatened by drought, air pollution, and climate change reducing forest floor humidity. Classified as At Risk - Declining, with populations declining in many parts of New Zealand.
Population
At Risk – Declining. Balantiopsis liverwort is sensitive to habitat disturbance, drought, and air pollution. Its populations have declined in many parts of New Zealand, particularly in areas with forest fragmentation and climate change. It is still found in some old-growth forests, but it is becoming harder to find.
Conservation Status
Not Threatened
Human Risk
harmless
Handling Note
common liverwort, safe to handle
Conservation Note
Endemic liverwort; not assessed by NZTCS as bryophytes are generally outside the scope of current threat classifications.
Te Ao Māori
No recorded Māori name distinguishes the balantiopsis liverwort from other liverworts. Liverworts were generally called pūkohu (mosses and lichens) or grouped with other small, damp-loving plants. The delicate, pale green mats with a pinkish blush would have been noticed. They looked like the colour of the dawn. Like the blush of a leaf. But no distinct name survives. The balantiopsis liverwort was not used as a medicine or a dye. It was too rare. Too delicate. Too easy to overlook. It was simply part of the forest. A quiet, beautiful presence on the bark. Now fading away.
It looks like green lace. Balantiopsis liverwort has creeping and branching stems. They form loose, leafy mats on the bark. The leaves are arranged in two rows along the stem. They overlap like the scales of a fish. The leaves are oval to oblong. With a rounded tip and a finely toothed margin. The colour is pale green to yellowish-green. Often with a pinkish tinge. A blush of rose that gives the species its name. Rosea means rose-coloured. It is the liverwort of the fading blush. The one that is slowly being edited out of the forest. What makes it special is the delicacy. Balantiopsis liverwort is one of the most delicate liverworts in New Zealand. Its leaves are thin and translucent. With finely toothed margins that give them a lacy, fragile appearance. The pinkish tinge is a blush of colour on the pale green leaves. This makes it one of the most beautiful liverworts in the country. It is the liverwort of the fading beauty. The one that is slipping away before our eyes. The one that makes you catch your breath when you find it. Why is it declining? Habitat disturbance and climate change. Balantiopsis liverwort needs old-growth forest. With stable bark surfaces, high humidity, and clean air. It is sensitive to forest fragmentation. This dries out the forest interior. It is also sensitive to drought. Which is becoming more common as the climate warms. It is the liverwort of the disappearing forest. The one that cannot survive in a changing world. The one that is being edited out of the ecosystem one patch at a time. The leaves lie flat against the bark. The leaf margins are toothed. Each tooth ends in a sharp point. The pinkish tinge is most visible on young leaves. And on plants growing in high light. Under a hand lens, the teeth are visible. Tiny spikes along the edge of the leaf. Biologically, the balantiopsis liverwort reproduces by spores. Released from capsules on short stalks. It grows on the bark of native trees. On rocks. And on rotting logs in damp, shaded forests. It is endemic to New Zealand. Found nowhere else in the world. A unique part of our natural heritage. To find balantiopsis liverwort is to find the delicate, pale green mats. With a blush of pink on the tree bark. They are beautiful, fragile, and fading. A quiet decline on the trunk. You need to look closely. And you need to be lucky. It is the liverwort of the fading blush. The one that is slowly being edited out of the forest. The one that reminds us that not everything lasts forever.
