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. |

English oak |
Quercus robur |
A very strange, unexplained stem!! Forest of Dean, Gloucestershire, England, UK. Not the result of a super long tree shelter! Root collar instability and total loss of apical dominance in early years may explain it? The crown was a stunted "lollipop" shape. |

English ivy |
Hedera helix |
A large, old stem growing up oak (Quercus petraea). Ogwen Woods, Bethesda, N. Wales, UK. Since sheep relish ivy, there are suspicions that this one got above their browse in a period of agricultural recession, maybe the 1920's. The fresh growth on the left is ungrazed because the wall behind was recently repaired. |

harvesting |
|
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. |

planting |
|
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. |
| 5170003 |
foxglove |
Digitalis purpurea |
Multi stemmed flowering plant next to a windrow of brash. Gwydyr Forest, N. Wales, UK. The site had been clear felled and replanted a couple of years previously. This plant probably came from the soil seed bank and was enjoying the brief opportunity before being overtaken by the next rotation of conifers. |

Tree planting. Establishment and protection. Tree shelters. Community Forest. Reclamation and restoration of coalfield/colliery/power station workings and spoil. NW. Midlands, UK. Landscaping on a widespread, industrial scale. Ground contamination widespread and often capped with top soil. The canes supporting the shelters were not strong enough, weed control could have been better and Voles (Microtus agrestis)were destroying stems! |

One of many tree shelter experiments that I have worked on. Here, oak(Quercus petraea), was the subject and can just be seen in some of the shelters. Earlier work had indicated the need to use strong stakes,hence those on the left. |

Juncus spp. |
View of Braich Melyn, Bethesda, N. Wales, UK. Moonrise over a forestry plantation of Sitka spruce (Picea sitchensis). Changes in land use. The dead tree in the plantation was oak(Quercus petraea), probably ringbarked, when the conifers were planted. Changes and declines in agricultural practices on marginal areas, such as this, allow the income of Rush and Bracken. |

European white birch |
Betula pendula |
View of old,walled field system. Braich Melyn, Bethesda, N. Wales, UK. Silver birch and Bracken slowly taking over as grazing pressure is reduced on this marginal ground. In time, if grazing was stopped, this view would naturally be dominated by a cyclical dominance of birch and oak. |
| 5169086 |
European white birch |
Betula pendula |
A UK native and a pioneer species but not very long lived. In UK, generally not regarded as a timber tree unless for firewood but it has great ecological value and is an important component of the Western oak woodlands in UK. Image from Braich Melyn, Bethesda, N. Wales. The foxgloves (Digitalis purpurea) in the foreground have benefited from the bracken (Pteridium aquilinum) having been killed off the previous year with herbicide. |
| 5169087 |
Sitka spruce |
Picea sitchensis |
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. |
| 5169088 |
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. |
| 5169089 |
Sitka spruce |
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. |
| 5169083 |
rhododendron |
Rhododendron ponticum |
An alien,invasive,weed species in much of the cooler,damper parts of western UK. Able to tolerate a wide range of situations it can rapidly swamp out all other plants and cause considerable damage to the local ecology. Now known to be a hybrid with R.maximum and R. catawbiense which confers greater cold hardiness. In UK it has also established a mycorrhizal association which compounds the problem. |
| 5169084 |
Sitka spruce |
Picea sitchensis |
Polytunnels, Forestry Commission nursery, Lob's Slack,Delamere,Cheshire,UK. These tunnels are fitted with misting systems for the bulk,vegetative propagation of genetically improved Sitka spruce(Picea sitchensis). |

parsley fern |
