Coastal Wattle
Coastal Wattle, also known as Sydney Golden Wattle, is a fast-growing Australian shrub or small tree that has become invasive in many of New Zealand's coastal environments.
Recognisable by its long narrow leaves and masses of bright golden-yellow flowers in late winter and early spring, Coastal Wattle spreads readily through seed and can quickly establish dense stands if left unmanaged.
Grows rapidly and forms dense thickets
In dune and coastal ecosystems, Coastal Wattle competes aggressively with native plants for light, moisture and space, reducing biodiversity and altering the natural structure of these fragile environments.
Seeds can remain viable in the soil for many years and are easily spread by water movement, soil disturbance and human activity, making long-term management and follow-up control important.
At Waikawa Beach, controlling Coastal Wattle helps create opportunities for native dune species to establish and supports the restoration of healthy coastal ecosystems.
Numerous small, puffy, pale to golden yellow flowers appear in cylindrical spikes
Leaves are hairless, occasionally curved, and usually have three prominent veins
