Bark beetles : the larger eight toothed bark beetle
The woodlands’ blog has reported on outbreaks of bark beetles in the States and Canada but as of 16th January this year, measures were put in place to protect the UK from the larger eight toothed spruce bark beetle (Ips typographus). This beetle has been a problem on continental Europe for many years; it has been estimated that Germany lost some 30 million cubic metres of timber (between 1945 and 1949) to bark beetles. Spruce is a commercially important species, with perhaps some 800,000 hectares in the UK. On the continent, the beetle has also been found living in pine, larch and douglas fir. The beetle was found in Kent last December. The special measures restrict the movement of spruce in a 50 km area around the outbreak. Details of this area can be found here. Read more...
Annual rings, drought and climate change.
Research workers in the States and Germany have been investigating the effect of drought on the subsequent growth of various types of trees. Because of climate change, droughts are expected to increase in frequency and severity.
The workers in the States found that trees took between two and four years to recover from drought and resume ‘normal’ growth.
The reduction in growth could be due to Read more...
Białowieża- “a national treasure for Poland and an international treasure for us all”
Białowieża is a forested area that lies on the border of Poland and Belarus. It includes some 1500 sq km of some of the tallest trees to be found in Europe, including towering hornbeams. It is a species-rich area, with carnivores such a lynx and wolves, 120 bird species (including the three toed woodpecker and pygmy owl), 60+ mammal species including the bison! The area has been described as a “national treasure for Poland and an international treasure for us all”.
The tracts of forest are special as they have never been felled, though it would be wrong to think of the woodland as ‘primaeval’ like the original ‘wildwood’. The woodland / forest supports a community through tourism, timber, hunting, honey and mushrooms, not to mention scientific researchers and the staff associated with the National Park. However, only 105 square km of the forest has been designated as National Park or a Unesco Heritage Site. Read more...
More productive forestry trees (and Dr Steve Lee).
Since 1960 commercial trees in the UK have become about 25% more productive. This has been achieved through selective breeding, mostly of Sitka Spruce and Scots pine where plants have been chosen for their rapid growth. It has also led to better quality timber which produces more sawlogs. Unfortunately according to the Forestry Commission's Steve Lee, no similar effort has been made with broadleaved trees so they have suffered a relative disadvantage compared to the progress with conifers. He says, "We dropped tree selection for broadleaved trees in the 1960s because it was thought to be not worthwhile."
Woodland types : Coniferous plantations
Coniferous plantations are found throughout the U.K. There are some 300,000+ hectares in England, 900,000+ hectares in Scotland, and circa 106,000 hectares in Wales. Large scale conifer planting ‘took off’ soon after the First World War. At about this time, the woodland cover had fallen to 5% (in Britain) so the Forestry Commission was established. This had the aim of ensuring that there would be a strategic reserve of timber.
Vast areas of ‘low grade’ land were pressed into service. Areas around Thetford and Kielder were used, as were some sandy coastal sites (e.g. Holkham in Norfolk) and many large tracts in Scotland (including the use of some natural peatlands). Read more...
Chatsworth Arboretum and Pinetum – highly managed woodlands
In the 1830s the 6th Duke of Devonshire, owner of the Chatsworth Estate in Derbyshire, was one of the first to plant a pinetum and arboretum. He did this in partnership with Joseph Paxton, who later became famous for building the Crystal Palace exhibition in London. Taking a few acres of grazing land above the great house at Chatsworth, they set about planting trees systematically in accordance with the botanical classification used at the time. It's very clear that both the Duke and Joseph Paxton had great fun in their creation of some large-scale landscape features. Read more...
VOC’s and Pine trees.
Boreal forest is found in Canada, Sweden, Finland, Norway and Russia. Essentially, it is coniferous forest with tree species such as pines, spruces, larches and aspens. In the U. K., this unique ecosystem is represented by the Caledonian Forest (a remnant of the vast sylvan wilderness that once existed here). One of the larger tracts of this native pine forest is the Black Wood of Rannoch.
One feature of the boreal forest or taiga is that it has areas of even-aged stands of trees. This uniformity arises through cycles of natural disturbance – from forest fires to outbreaks of insect pests such as pine beetle or spruce budworm, which periodically kill off large sections of forest – but these areas, in turn, regenerate.

Greenridge – my wood.
Having been born and brought up in rural Devon and then subsequently spending a career of 50 years at sea, the prospect of retirement with all its encumbrance of zimmer frames and wheel chairs was not sitting too comfortably on my shoulders. A year into this experience, at about the time the wife stopped talking to me, and with the feeling of guilt experienced every morning of really not doing very much constructive with my life, except walk the two Springers the obligatory six miles a day along the coast outside my home - it really felt as if the rot was well and truly starting to set in. That is until one day, whilst exploring a quiet part of Northumberland, I espied a Woodlands.co.uk for sale sign. Read more...
