A study of the effect of weeds on diameter and height growth of young plantation-grown radiata pine was undertaken in Rolleston Forest (Selwyn District) in the Christchurch region of the South Island of New Zealand. The objectives of the study were to identify practical and easily measurable indices of competition and to provide a method of quantifying inter-specific competition from non-crop vegetation in young plantations by deriving indices of competition using neighbourhood predictors. This thesis gives full details of the materials and methods used for the study, data analysis tools and procedures, as well as results of the study. One of the indications by some of the results of the study were that conventional weed control regimes as commonly used by forest managers in the region resulted in individual crop trees still experiencing high levels of inter-specific competition. The implications of these findings on present and future vegetation management regimes in the area and a brief mention of the economic implications are also mentioned herein.
