nursery operations |
|
"Electrodyne" bench.Forestry Commission,Corris,Wales. Used for applying an electrostatically charged spray of persistent insecticide to forestry plants prior to planting.The conveyor is earthed and thus ensures that the spray only attaches to the plants. Efforts to minimise chemical use as well as the withdrawl of many insecticides have encouraged research into other methods of control of Hylobius and Hylastes. Field scale use of nematodes and stump removal have given promising results. |

Forestry harvesting and extraction. Forestry Commission, Cannock, UK. Modified "Thetford Tongues" for skid extraction of Pine (Pinus nigra maritima). Mounted on Ford County tractor. This was a much favoured combination for "hotlog" extraction at Cannock in the 1980's-90's. County and Ford County tractors were for years the stalwart workhorses in UK farm and forestry and still have a place, as well as a small but dedicated fan base. |

|
Tree planting and establishment techniques.This was a large demonstration plot in an ex-industrial area of NW Midlands. UK. Planted to show participants in a Community Forest project various techniques. In this view,black plastic and wood chip mulches are shown. Control of competitive weeds is very important in the establishment of young transplants. The Short-tailed Vole (Microtus agrestis) can be a problem under the plastic sheet mulch, finding it much to their liking and damaging/destroying the base of the trees by gnawing. |

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. |

kapuka |
Griselinia littoralis |
A New Zealand shrub or, in time, a small, multi-stemmed tree.Not hardy throughout UK, especially inland, but in the milder West it makes an excellent hedge or wind break being very tolerant of salt laden winds. Very easy to propagate from Autumn hardwood cuttings. In favoured areas it will set seed but as yet does not seem to be an invasive. Can be cut back hard or even coppiced if required. |

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. |
