Climate variability is one of a number of factors that can affect the success of tree plantings. One way to accommodate climate variability in decision making is to use seasonal climate forecasts (SCF). SCF have been used to improve a range of on-farm decisions, however, their usefulness in natural resource management, such as tree planting, has received much less attention. The aim of this project was to use local knowledge to assess the usefulness of SCF for improving the success of tree planting in south-east Australia. Forty-one interviews were conducted with revegetation practitioners, landholders and nursery owners across the southern five catchments of New South Wales: Central-West, Lachlan, Murrumbidgee, Murray and Southern Rivers. The results indicated that the amount of forecast skill and lead times did not correspond well with information needs of landholders, practitioners and nurseries. Furthermore, climate was considered to be of secondary importance relative to site preparation in affecting the success of plantings. Nevertheless, one quarter of the interviewees used SCF in their tree planting decisions, half would only use SCF if they were sufficiently accurate and timely and only one quarter did not and would not consider using SCF. Since the timeframes over which tree planting decisions are made vary from a few weeks to a few years, SCF may prove to be most useful for those people who wish to manage climatic risk and who make the majority of their decisions within three months of planting, when forecasts are the most accurate. © 2010 by Nova Science Publishers, Inc.
