Hon Giz Watson questions the Minister for Environment about adjusting sustainable yield projections in the Forest Management Plan to account for declining rainfall, referencing an EPA audit. The Minister's response indicates consideration of rainfall outlooks in future planning and adaptive settings within the current plan.

FOREST MANAGEMENT PLAN — EFFECTS OF DECREASING RAINFALL
Given that, in making assumptions about the growth rate of native forests, the Department of Environment and Conservation has not taken into account further decreases in annual rainfall, and that the Environmental Protection Authority’s recent audit report on the implementation of the forest management plan warns that declining rainfall and other threats will seriously reduce the regrowth capacity of forests in the medium and low rainfall zones, I ask — (1) Have the minister and DEC adjusted their projections for sustainable yield and allowable cut of sawlogs and other forest products to take these facts into account? (2) If yes to (1), in what way or ways? (3) If no to (1), why not? Hon DONNA FARAGHER

I thank the honourable member for some notice of this question. (1)–(3) In response to question without notice 780 asked on 13 October 2010, I informed the member that I support the sustainable harvesting of native forest carried out in accordance with the forest management plan, and that the Environmental Protection Authority’s advice outlined in its bulletin 1362 and long-term rainfall outlooks will be considered in the preparation of the next forest management plan. This is consistent with the EPA’s advice. I further advise that the current forest management plan includes a number of adaptive settings that take into consideration the possible impacts of climate change on sustained yield of wood. The Department of Environment and Conservation continues to undertake inventory to monitor forest growth and health, to improve predictive growth modelling, and to better quantify the impact of factors that influence tree growth rate. New information will be incorporated in the models that will be used to determine sustained yield figures for the next forest management plan.
