Fencing stakes, mid-Wales. These had been pressure treated with "Tanalith C"hence the colour. They had come from low/no value Sitka spruce(Picea sitchensis)thinnings and tops, gaining added value. Sitka spruce grows rapidly in the Welsh climate but the timber is not at all durable outside. Correct pressure treatment may give these stakes a service life of over 20 years. |

Picea sitchensis |
Forestry Commission nursery,Lob's Slack,
Delamere,Cheshire,UK. One of the tunnel bays in image 5169084 filled with cuttings of genetically improved Sitka spruce. Once rooted and then hardened off, they are lined out to grow on before going to the forest. Although the subsequent plants are more expensive than those grown from open pollinated seed they have greater vigour,better form and better timber.Their stems tend to be thicker,at planting,thus less prone to Hylobius damage. |
