tanekaha with fine feathery foliage on steep slopes

Size
Height: 15–20 m
Lifespan
200–400 years
Diet
Herbivorous – absorbs nutrients through extensive root system. A slow-growing, shade-tolerant tree that thrives in well-drained, acidic soils. Prefers stable, undisturbed forest conditions. Does not tolerate drought or fire.
Habitat
Lowland and montane forests, particularly in well-drained, acidic soils. Prefers sheltered valleys and slopes with stable humidity. Often found in association with kauri, rimu, and taraire. Requires mature forest with minimal disturbance.
Range
Found throughout the North Island and northern South Island in lowland and montane forests. Most common in North Island (Northland, Auckland, Waikato, Coromandel, Bay of Plenty) and northern South Island (Nelson, Marlborough).
Endemism
Endemic
Main Threats
Habitat loss from forest clearance is the primary threat. Also threatened by slow regeneration, predation of seeds by rats and possums, and competition from invasive weeds. Old-growth stands are increasingly rare due to historical logging for timber.
Population
Tanekaha is a distinctive celery pine with feathery, fern-like phylloclades (flattened branchlets). Found in lowland forests of North Island and northern South Island, often in association with kauri. Wood traditionally used by Māori for making bird spears and other tools. Bark used for tanning leather, giving the tree its common name.
Conservation Status
Not Threatened
The feathery celery pine of the northern forest. A tree that looks like a fern. Tanekaha has a foliage that looks more like a fern than a tree. At fifteen to twenty metres in height, it is a medium-sized tree, with a straight trunk, dense crown, and distinctive, feathery, fern-like phylloclades (flattened branchlets) that give it a soft, lacy appearance. The bark is dark brown and furrowed. A tree that wears a disguise. A tree of the kauri forest. Tanekaha grows in lowland and montane forests of North Island and northern South Island, often in association with kauri, rimu, and taraire. Prefers sheltered valleys and slopes with stable humidity, requiring mature forest with minimal disturbance. A tree that needs the old forest. A slow-growing, long-lived species, taking centuries to reach maturity. It produces small, berry-like cones eaten by birds, particularly kererū and tūī, which disperse its seeds across the forest. The wood is pale, straight-grained, and durable, used by Māori for making bird spears and other tools. A tree that made weapons. Tanekaha was also valued for its bark, which is rich in tannins. Early European settlers used the bark for tanning leather, giving the tree its common name (tanekaha means tanning bark). The bark was stripped from trees, ground into a powder, and used to treat animal hides, producing a soft, durable leather. A tree that turned animal skins into clothes. To see a Tanekaha is to see a tree that has been shaped by both nature and culture. Its feathery foliage is a reminder of the beauty of the New Zealand forest, and its bark is a reminder of the ingenuity of the people who lived here. The kauri forest is dark. The tanekaha grows, feathery and fern-like, straight trunk rising toward the light. The birds eat its cones. The bark was stripped for leather. The tree does not complain. It has been here for centuries. It will be here as long as the forest remains.
