Gorse is a nitrogen-fixing plant, meaning it extracts nitrogen from the air to help it grow. Research shows this process causes gorse to leach a huge amount of nitrogen into ground water, which then makes its way to the lake. Too much nitrogen in the lake causes algal blooms to grow, damaging the overall quality of water.
Put simply, gorse is a stubborn weed that offers no land productivity or environmental benefits. It’s also hard to eradicate – if left unmanaged after clearing, it will most likely grow back.
The Bay of Plenty Regional Council is helping landowners remove gorse off their property through sustainable land use changes.
To help you eradicate mature gorse once and for all, we may be able to help support the conversion of mature gorse to productive forestry, native bush, or other low nitrogen leaching activities.
