Parliamentary Questions


Question Without Notice No. 338 asked in the Legislative Council on 9 April 2019 by Hon Diane Evers

Parliament: 40 Session: 1

ALCOA — JARRAH FOREST REHABILITATION

338. Hon DIANE EVERS to the Minister for Environment:

I refer to the minister's response to my question without notice 138 on 12 March 2019.

(1) How much jarrah forest, rehabilitated by Alcoa after bauxite extraction, has been returned to the state government to manage since 2000?

(2) Will the minister please table any maps showing this area?

(3) What management has the government undertaken on these forests since being returned to its control, and what has been the cost annually to do so?

(4) With reference to the thinning trials and planting at lower stem densities undertaken by Alcoa, when did this occur?

(5) Have any reviews been conducted on the successes or otherwise of these trials; and, if yes, what was the result?

Hon STEPHEN DAWSON replied:

I thank the honourable member for some notice of the question. Member, just note that this question was asked on 2 April, so the answer is current as of that date.

(1) A total of 1 355 hectares.

(2) I table the attached document.

[See paper 2580.]

(3) These areas are part of the broader state forest mosaic managed by the Department of Biodiversity, Conservation and Attractions to protect the natural environment and balance the many social and economic benefits the community receives from these forests. It is not possible to provide a separate cost for the specific areas returned to the state.

(4) Thinning trials occurred in 2002 and were repeated during 2013 to 2015. Separate trials on establishing lower stem densities commenced in 2009.

(5) I am not aware that Alcoa has undertaken any reviews; however, monitoring is undertaken by Alcoa and it is responsible for reporting any results.
