edible shoots prized for centuries

Size
Height: 30–60 cm
Lifespan
10–20 years
Diet
Not applicable (fern)
Habitat
Lowland and coastal forests, stream banks and damp, shaded sites. Prefers moist, fertile soils with partial to full shade. Often found on banks and among rocks in the forest understorey environment.
Range
Throughout New Zealand from Northland to Stewart Island. Most common in lowland and coastal forests. Also found on the Chatham Islands and in Australia, indicating a wider distribution beyond New Zealand shores.
Endemism
Native
Main Threats
Habitat loss from land clearance is the primary threat to populations. Browsing by introduced possums and deer poses additional risk. Climate change affecting forest habitats may impact future distribution and stability.
Population
Populations are considered stable and widespread. The species is common in lowland forests throughout New Zealand. It is threatened by ongoing habitat loss and browsing. Protection of lowland forest is important for long-term survival.
Conservation Status
Not Threatened
This fern is the same species as the hen and chicken fern. Asplenium bulbiferum. But while the hen and chicken fern is known for its bulbils, pikopiko is known for its koru. The young, coiled fronds are a traditional food. Gathered in spring. Eaten raw or cooked. They are crisp, tender, and mild. A taste of the forest waking up after winter. The culinary value defines this perspective. It shifts the focus from morphology to utility. The plant grows in lowland and coastal forests throughout New Zealand. It is common. Widespread. Not threatened. But its habitat is threatened. Lowland forests are cleared for farms. For housing. For roads. The fern survives in fragments. In reserves. In the corners of the landscape that have not yet been converted. The persistence is precarious. It relies on the remaining patches. The fronds are soft, bright green, and finely divided. Lacy and delicate-looking. They arch up from the base. Reaching about a metre in length. The bulbils appear on the upper side of the frond. Usually near the tip. Looking like small green bumps. As they grow, they develop roots and leaves. The frond begins to droop under their weight. The structure is functional. It supports reproduction. Reproduction occurs by spores and by bulbils. The bulbils are tiny plantlets that grow on the fronds. They drop to the ground and root. This creates new plants. It is a master of asexual reproduction. It surrounds itself with its offspring. The strategy is efficient. It minimises risk. It maximises local presence. The colony expands from the parent. In a world where reproduction is risky, where spores might not land in the right place, where seeds might get eaten, pikopiko has found a better way. It makes babies on its own body. It drops them at its feet. It surrounds itself with its offspring. The proximity ensures survival. The method is reliable. It bypasses the uncertainties of wind dispersal. But the forest is shrinking. The lowland forests are being cleared. The pikopiko still grows in the fragments. Still sends up its koru each spring. Still offers its tender fronds to anyone who knows where to look. But for how long? The question lingers. The habitat loss continues. The fern adapts to the edges. It persists in the margins. It waits for the next season. The cycle continues despite the pressure. The resilience is notable. It endures in the modified landscape. It remains a source of food. It remains a symbol of the forest. No one told it otherwise.
