Northland launch campaign on fork-leaved hakea
Jul 13, 2004
Author:

Fork-leaved hakea is fast growing, shade tolerant, nutrient sucking, drought resistant, salt resistant and is a serious weed problem in parts of Australia and South Africa. Two sites have been found at Whangarei Heads. You can help save Northland from this weed.

The Department of Conservation is launching a campaign to survey Northland for fork-leaved hakea and if possible to eradicate it, before it spreads further. We are very interested in discovering the distribution of this species in the wild and in gardens around Northland.

You can help by letting us know if you have seen it and the exact location. It would also be helpful to know how to contact you so staff can come and look at the site. The Department will remove it for FREE if you wish, and provide native plants as replacements.

Fork-leaved hakea is a fast growing tree native to Western Australia and it is been declared an invasive weed in South Africa and parts of Eastern Australia.

Fork-leaved hakea occupies open, sunny positions, although will tolerate some shade. It has the potential to overtop or replace other plants. Hakeas have a distinctive root system (proteoid roots) consisting of tight groupings of many small “rootlets”. These enable the plants to more efficiently take up nutrients from the nutrient-deficient soils where they occur, rapidly replacing native plants.

In addition, they are drought, salt and wind resistant, and release large quantities of seeds from hard distinctive nut-like pods. Hakeas are regarded as the hardiest genus of the Australian Proteaceae, this means it has the potential to become a serious weed if allowed to spread.

Fork-leaved hakea look much like other hakeas, however the stiff leaves are forked into many needle-like leaflets that have pointed tips. The sharpness of the leaf points and the density of the foliage originally made it popular as a hedging plant. Clusters of fragrant small white flowers bloom in April to August.

There is no report of fork-leaved hakea in Northland other than two sites found at Whangarei Heads in 2003.
