Abstract: Damage to exotic trees in North Canterbury caused by severe drought conditions during 1955-56 is reviewed. The effects are discussed under five headings, from slight foliage injury to death of trees. The species concerned are listed under six drought-damage categories; these in turn are related to site differences based on soil type, topography, rainfall, and other variables. It is shown that in many places in Canterbury a deficiency of soil moisture influences tree growth and survival.
Broad recommendations are made for assessing the potentialities of sites in the area, and emphasis is placed on the role hardwoods can play in afforestation on the drier sites.
