❓ A WA parliamentary question investigates herbicide use in post-logging thinning operations in state forests, including water catchment areas, and seeks details on precautions, trials, and effectiveness. The response provides some specifics but deflects detailed information on trials to another Minister.

QuestionView source ↗
With regard to post-logging thinning operations in State Forests, will the Minister please advise -
(1) In what forest blocks has herbicide application to cut stumps been used in -
(a) 2004;
(b) 2003; and
(c) 2002?
(2) Is this method used in forest blocks which are catchment areas for -
(a) drinking water supplies; and
(b) non-drinking water supplies?
(3) What precautions are required regarding spillage, the amount of herbicide solution used on each stump, the concentration of herbicide solution used, and disposal of excess herbicide solution?
(4) In the case of drinking water supply catchments, are any additional precautions required?
(5) If yes, what are they?
(6) If not, why not?
(7) What trials, if any, have been carried out regarding the effectiveness of thinning operations for various intended outcomes?
(8) Where were the trials conducted and for what reasons?
(9) What were the outcomes and costs of those trials?

(b) Arklow, Catterick, Darrell, Hovea, Hunt Inglehope, Mullalyup, Preston, Towers, Wells. (c) Arklow, Curara, Darrell, Kennedy, Hedges, Plavins, Preston, Pindalup, Ross. 2.(a) & (b) Yes 3. Precautions recommended by the manufacturer and relevant bodies and agencies are applied to the storage, transport, application and disposal of chemicals. 4-6. Additional precautions are not required for water supply catchments because the precautions taken are considered adequate in all circumstances. The Forest Products Commission liaises with the Water Corporation about this and other aspects of management of harvesting and silviculture operations in active catchments. 7-9. The scope of these questions is extremely broad given the extent of research into forest thinning over many years. Some relevant references to which the Hon Member may wish to refer are: Abbott, I. and Loneragan, O. (1983c) The response of jarrah (Eucalyptus marginata) regrowth to thinning. Australian Forest Research 13, 217-29. Dell, B., Havel, J.J. and Malajczuk (1989) The Jarrah Forest. Kluwer Academic Publishers. 408 pages. Stoneman, G.L, Crombie, D.S., Whitford, K, Hingston, F.J., Giles, R, Portlock, C.C., Galbraith, J.H. and Dimmock, G.M. 1993. Growth and water relations of Eucalyptus marginata (jarrah) stands in response to thinning and fertilisation. Tree Physiology, 17; 267-274 For more specific information on thinning trials in the jarrah forest it would be more appropriate to direct questions through the Minister for the Environment as the Department of Conservation and Land Management is the custodian of this information.
