Are we still planting cypresses on the right site?

This article addresses the siting requirement in planting cypresses. As a general macrocarpa has performed best in the cooler parts of New Zealand, principally but not exclusively the South Island. Several hypotheses have been suggested for the apparent increase in the incidence of cypress canker including changing climatic factors, the influence of planting stock genetics, planting off-site, a general increase in inoculum loadings as a result of increased plantings and possibly a change in the virulence of cypress canker. Other cypress hybrids, namely the Leylands and Ovens cypress are gaining in popularity. These hybrids are proving to be a reliable choice for those sites once considered good for macrocarpa.
