Gorse (Ulex europaeus) is a major invasive plant species in New Zealand and millions of dollars are spent on its control.
Gorse is one of the most widely recognised agricultural weeds in New Zealand. It covers 700,000 hectares (1,700,000 acres) at varying densities — a total of 5% of the land area of New Zealand when excluding existing indigenous forest, vegetated sub-alpine and alpine areas.[1]
Introduced from Western Europe in the very early stages of European settlement, it was recorded by Charles Darwin during his voyage through New Zealand waters in 1835 as growing in hedges in the Bay of Islands.[2] Its spread and development as a weed in New Zealand's temperate climate was rapid, but settlers failed to recognise the threat; gorse seed continued to be imported and plantings deliberately established into the 1900s. The seed can lie dormant on the ground for up to 50 years, germinating quickly after the adults have been removed. Unfortunately, most methods of removing adult gorse plants, such as burning or bulldozing them, create the ideal conditions for the gorse seeds to germinate.
Large spreading infestations over hundreds of hectares resulted, peaking in the late 1940s. Gorse became New Zealand's most costly weed to control and total eradication with current technology seems impossible.
