Harvesting in progress (Photo: R. MacCurrach)
I've written about the small commercial woodland at Ty Gwyn in an earlier post. This year, Ty Gwyn became a 'Certified Woodland' as the management has been certified to the Sustainability Criteria of the Forest Stewardship Council.
The commercial spruce from about half of the woodland at Ty Gwyn is being harvested in late 2009. The timber has been sold as "standing trees" and so the purchaser is responsible for felling and carrying away.
Harvesting in modern woodlands is largely automated and the 'Harvester' is central to the operation. This tracked or partially-tracked vehicle can work in difficult terrain. The jib is a little like that on a 'JCB' but instead of a bucket, there is a complex harvester head which splits so as to pass around the trunk of the tree to be felled. The head then firmly grasps the trunk and a built-in chain-saw cuts through the trunk. The felled tree is then lowered to a horizontal position so that minor branches can be automatically stripped as the trunk is passed through the harvester head. Finally, the trunk is chain-sawed into preset lengths which are laid on the ground to await collection by the Forwarder.
The Forwarder is another vehicle adapted for harsh conditions, usually with some sort of 'Hiab' crane for lifting logs into the load space. Forwarders are often articulated with large tractor-type wheels. Their job is to transfer logs to a suitable loading point with road access where conventional timber lorries can take away the logs.
