(1) What is the yield of first, second and third grade Jarrah saw logs from the marginal Jarrah areas to the west of Sues Road near Brockman Highway, compared with the total tonnage of trees cut in those areas?
(2) What is the normal yield of Jarrah saw logs of the different grades in the main areas harvested for Jarrah saw logs?
(3) What happens to the rest of the timber cut from the marginal Jarrah areas as described above?
(4) If these areas of forest are not designated as being old growth forest, can the Minister inform when those areas were previously harvested for timber production?

(1) It has been assumed that the area referred to encompasses the Schroeder 0503 and 0511 coupes located immediately west of Sue's Road and to the north of Brockman Highway.
The area of these two coupes totals 2573 hectares, of which 1094 hectares was harvested over approximately a four year period from 2008 to 2012. The area produced a combination of first, second and third grade sawlogs, as well as bole sawlogs. As bole sawlogs include portions of all sawlog grades, it is not possible to provide a breakdown of only first, second and third grade logs.
The total quantities produced from these coupes from 2008-12 are:
Bole sawlog - 3402 tonnes
First grade sawlog - 3076 tonnes
Second grade sawlog - 1550 tonnes
Third grade sawlog - 675 tonnes
Other green jarrah products - 4800 tonnes
Total quantity from this area from 2008-12 is:
Sawlog products - 8703 tonnes
All green jarrah harvested products (including sawlog) - 13 503 tonnes.
Note that this figure does not include the dead wood products that were harvested during this operation.
There is no measurement taken of total quantity of trees cut, only the quantity of products removed from harvested trees.
(2) The yield of sawlog from the jarrah forest is variable. It can range from five tonnes per hectare to greater than 50 tonnes per hectare. On average, the yield of jarrah sawlog products is approximately 20-25 tonnes per hectare.
(3) A proportion of the timber that does not achieve sawlog quality is marketed as domestic firewood. Green firewood makes up the majority of the 4800 tonnes of other green products identified in (1). Timber remaining after the removal of domestic firewood remains in the forest. In these coupes the area has subsequently been made available by the Department of Environment and Conservation as a Public Firewood Area where the public can utilise remaining accessible timber from the forest floor.
(4) The area does not contain any patches of designated old growth forest. Cutting records indicate that approximately 95 per cent of the area was harvested in the 1950s with the remainder being harvested in the1960s.
