Improved growth of stands To maximise the growth of pruned stems, plantations are thinned at around age 10-12 years. As well as improving the silvicultural management of the stand, thinning also provides a good supply of pulpwood and small sawlogs. After thinning, approximately 300-350 stems are left to grow into high quality sawlogs and veneer logs. Forestry Tasmania also has a program to model the risk of windthrow to a stand that allows planners to schedule thinning at an appropriate time to avoid loss or damage to the stand. Product recovery Forestry Tasmania has two main processes in place to ensure the recovery of wood volumes and values are maximised. This includes the carrying out of pulpwood audits at mills and landings to determine the presence of any sawlogs that may have been misclassified as pulpwood and the conducting of post logging residue assessments (LRAs) to quantify the merchantable forest residue remaining after harvesting operations. Information collected from the pulpwood audits that conducted in 2007/08 indicate that 59 tonnes (0.04 per cent) of sawlogs were recovered out of total 156,016 tonnes audited. This was based on a sample size of seven per cent, which is over the prescribed standard of five per cent. Forestry Tasmania is committed to maximising the use of all felled trees from harvested areas. This is achieved through the selection of craftwood, special species timbers, high quality sawlogs and veneer with the remainder being available as pulpwood where it meets specification. In 2007/08 LRAs were conducted in 93 harvested areas. These assessments are a measure to ensure the efficient removal of forest products, and minimise merchantable wood being left on the forest floor. The standard of less than five merchantable tonnes per hectare was achieved in 92 per cent of the production areas sampled that represented a decrease of five per cent over last year’s performance. Contractors were required to return to remove residual timber in five instances where the target was not achieved. 6,187 480 139 Special species timbers Special species timbers have an iconic association with Tasmania. They are used to produce high value furniture and craftwood products. Examples include blackwood, black-heart sassafras, myrtle and celery-top pine. Forestry Tasmania is committed to the ongoing supply of these timbers to these important industries. With the exception of blackwood, the other special species are currently mostly derived from harvesting operations in wet eucalypt forests (predominantly oldgrowth). As a result of moving towards non-clearfell harvesting techniques, the volumes of special species timbers from this resource is anticipated to decrease. To accommodate this, approximately 5% (36,000 hectares) of the native forest wood production areas within State forests have been designated as special timbers management units (STMUs). Such units have defined management prescriptions and will be selectively harvested based on ecological requirements. 1,104 1,427 608 621 11,137 blackwood blackheart sassafras celery top pine white sassafras eucalypt / mixed species silver wattle myrtle Huon huon pine Figure 14. Breakdown (in tonnes) of the individual species making up the total quantity of high quality special species sawlogs.
During 2007/08, 21,703 m 3 of high quality special species sawlog was sold, with blackwood (11,137 tonnes) making up 51 per cent of this volume. In addition to this volume of high quality sawlogs, Table 8 shows the volumes of special species made available for craftwood purposes. In association with Forestry Tasmania, the Woodcraft Guild Tasmania, has commissioned a study into Tasmania’s woodcraft industry. The project will involve people who work in and depend on special timbers including sawmillers; manufacturers of high-value finished goods such as furniture, boats and musical instruments; hobbyists, and anyone else who uses native timbers from Tasmanian forests for commercial and non-commercial purposes. The study will provide an overall profile of the woodcraft sector and its characteristics and will help develop a comprehensive understanding of: • • • • the number of people and types of jobs involved economic value of these enterprises type of goods being produced how value is being added to raw materials to generate the valuable finished goods. The study will also look at skills development, growth, and the use of technology in milling, design, production and distribution. Table 8.
