The issue

When conifers were introduced to New Zealand in the 1800s, few people understood how they would thrive here. Since then, wilding trees have spread from forests, erosion plantings and farm shelterbelts out into the surrounding countryside.

These trees can quickly form impenetrable forests of no economic value.They make farms unusable, take over native ecosystems, use up scarce water, and alter iconic landscapes.
