Northmoor Trust's Forestry Research
Northmoor Trust's Forestry Research
The Northmoor Trust tree improvement programme was established at Paradise Wood in 1992. The programme includes breeding trials of 60,000 (mainly broadleaved) trees, improving the quality and, therefore the value of British forests.
This will reduce reliance on imports, maintain woodland in our landscape and reduce our global footprint.
Northmoor Trust's Forestry Research
- The research follows traditional selection and breeding techniques, employed by land managers for centuries. The best individuals are selected from across a species range. (perhaps from several countries).
- Seeds are then collected, grown under uniform conditions in a nursery, and then planted out in experimental trials where they undergo a rigorous, prolonged (15 years) testing phase. After testing, those individuals that are least good are culled from the trial, to leave the best performing individuals to cross fertilise.
- Trials are replicated across a number of separate sites to ensure that those trees that perform best, do so because they ARE best and not just growing well in one location. That is to say, an individual is superior over other individuals across a wide range of sites.
Walnut - An Alternative To Tropical, Dark Hardwood
- The Northmoor Trust is currently working on and promoting walnut as an alternative to tropical, dark, hardwood species.
- Walnut is not native to Britain, but was introduced by the Romans as a food source, and, more recently, from North America in 1656. It was valued for fruit (fresh, pickled and dried) and timber (furniture, gunstocks).
- There are several species, although only two are of interest in Britain today the common or English walnut (Juglans regia) and the black walnut (Juglans nigra).
- Foresters are now keen to plant walnut as it is one of the most valuable hardwood species. Good quality veneer walnut sells for £1600 per m3 whilst oak is valued at £300 per m3 (at 2004 prices).
- They are however concerned by proneness to frost damage and site sensitivity and hitherto walnut has had a low research priority in the UK.
- There is increased potential with the likelihood of future milder climates. The Northmoor Trust is doing extensive research on both walnut species, believing in their great potential and immense commercial value.
Tree Species and Climate Change
- Existing UK tree species need help to survive in the expected climate change.
- The Trust is developing research to test new sources of our native trees such as ash, oak, rowan and beech to help them cope with predicted climate change.
- Beech is a characteristic species of the chalk escarpments of southern Britain. It could disappear by 2080 unless we assist the species to adapt by sourcing material from further afield.
