New Zealand’s restiad bogs are most commonly found on low lying, flat and poorly drained environments but can also occur in montane and subalpine zones. The three main restiad bog species are:
- Empodisma minus (found in North, South, and Stewart Islands)
- Sporadanthus ferrugineus (found in North Island)
- Sporadanthus traversii (restricted to the Chatham Islands)
Restiad bogs are those characterised by plant species of the Restionaceae family and are most extensively developed in New Zealand.
The Restionaceae comprises jointed rush-like herbs with rigid or flexuose above-ground stems and reduced scale-like sheathing leaves growing on low fertility, seasonally moist or wet soils.
