Alison and John Smithies are sitting in front of wilding trees near Ōhau, where a few years previously there had been only tussock. Wilding trees spread from established plantations by wind-blown seed and establish themselves in open country or native forests. Their spread into tussock grasslands in the South Island is a major concern. In the Ōhau region the most common wilding trees are Pinus contorta and Pinus ponderosa.
