Pine Plantation Rotation

  1. 1. Timber Production in NSW State Forests<br />The pine plantation rotation<br />
  2. 2. Radiata pine<br />Radiata pine is a native tree of North America<br />It is grown commercially in Australia and supplies timber for 1 in 4 houses built in NSW<br />
  3. 3. Where is it grown?<br />Radiata pine plantations are located near Bathurst, Tumut, Bombala and Walcha<br />It is also grown commercially in New Zealand, Chile and Spain<br />
  4. 4. What is a plantation?<br />Plantations are like farms for trees<br />Plantations have a cycle of about 32 years<br />
  5. 5. Age 0 - Growing the seeds or cuttings and preparing the site<br />Germinate the seeds or establish cuttings<br />Seed is sown during September and October ready for planting from June to August the following year<br />The containerised nursery at Tumut produces 10 million seedlings each year<br />
  6. 6. Age 0<br />The site needs to be prepared for planting<br />Plantations are grown on cleared land<br />Site preparation involves ripping (breaking up compacted soil with a bulldozer) and mounding (creating rows of soil mounds to allow young seedlings to establish their roots quickly)<br />
  7. 7. Age 1 – Planting the Seedlings<br />Planting takes place in winter when the seedlings are dormant (not growing)<br />One seedling is planted every 2.5 metres along the rows of mounds<br />About 1000 plants / hectare<br />
  8. 8. Age 2 – Seedlings grow into small trees<br />After two years the seedlings reach about 2 metres in height<br />Competing vegetation is suppressed<br />Fertiliser is used to give plants a boost<br />
  9. 9. Ages 13, 21, 28 - Thinning<br />Thinning is where the smaller and weaker trees are removed allowing the remaining trees more space, light, water and food to help them grow <br />Timber removed during thinning is mostly used for pulpwood and processed into woodchips for newspaper, particle board and kitchen cupboards<br />
  10. 10. Age 32 – Final Harvest<br />Plantation pine trees are harvested between age 30 and 35<br />The logs from this harvest produce timber for houses and furniture<br />
  11. 11. What machine is that? <br />A feller buncher is used to cut the trees down.<br />It is a vehicle with tracks which rotate like an excavator and moves through the forest felling and bunching trees into a clear area. <br />
  12. 12. What machine is that?<br />A processor looks like an excavator or feller buncher. <br />It picks up the trees, removes the branches and cuts the log into different lengths. <br />
  13. 13. What machine is that?<br />A forwarder is a large vehicle with rubber tyres. <br />It has a cabin at the front and an arm with a grapple in the centre for loading logs into the tray at the back. <br />The forwarder picks up the logs and takes them to the log dump <br />
  14. 14. What machine is that?<br />Cable logging equipment is often used in steep country because it is the most efficient option and it minimises erosion <br />A yarder with a vertical pole has a skyline cable extends down into the forest to where the trees are being logged <br />The trees are felled by a person with a chainsaw and are attached to the cable. <br />They are then pulled up to the yarder where the logs are processed and loaded onto a truck <br />
  15. 15. What happens next? <br />Logs are carried by trucks to sawmills where they are sawn and dried to produce timber<br />
  16. 16. What products are made?<br />Pulpwood is used to make paper, particle board and kitchen cupboards<br />Small logs become treated posts for landscaping<br />Sawlogs are used for furniture and house frames<br />
  17. 17. After harvesting, what’s next for the plantation?<br />Back to Age 0 – a new plantation <br />After harvesting the trees, the land is prepared for a new pine plantation and the cycle continues<br />
  18. 18. What are growth rings?<br />A radiata pine tree adds a growth ring on the outside of its trunk under the bark each year. <br />The colour and thickness of the rings are affected by the season – spring produces a lighter coloured ring and summer, a darker ring<br />
