New Zealand has 194 native species and 35 introduced species of ferns and lycophytes. They range from freshwater to alpine habitats, and from just a few millimetres long to 20-metre-tall tree ferns. Just under half of the native species cannot be found anywhere else.
Dominant in native bush, and important traditionally to Māori for food and medicine, ferns have also become pervasive as a symbol of New Zealand identity. The fern motif is featured in commercial logos, creative design, and on national sports team jerseys.
