    Norway maple (NOM)

    Norway maple is a large tree and the most widespread of the European native maple species. Introduced to Britain in 1683 it has been widely planted but is mainly known for its horticultural interest. Cultivars such as the variegated leaved ‘Drummondii’ and purple almost black leaves of ‘Crimson King’ are frequent trees in parks and gardens. An adaptable species suited to the climate and conditions of Britain and has become naturalised in some areas. Norway maple is categorised as a Secondary tree species.  These are species that have demonstrated positive silvicultural characteristics in trial plots but gaps in our knowledge constrain their wider use. These species are being actively evaluated to increase understanding and inform future deployment.

    Common walnut (CWA)

    The common walnut is a long lived large, deciduous tree, reaching a height up to 25+ often with an expansive crown on a large trunk. It has been widely cultivated throughout its range for thousands of years and is thought to have been introduced to Britain by the Romans. In Britain it is mainly seen as a tree in urban parks and gardens. The fruit or nuts are widely used as a food with other parts used in various traditional medicines. The wood is durable, strong attractive and prized. With a warming climate and its potential as a high value timber tree it could offer a place as an alternative to ash on good sites. The additional value of edible nuts could also see this species considered for Agri-forestry planting. Common walnut is categorised as a Secondary tree species.  These are species that have demonstrated positive silvicultural characteristics in trial plots but gaps in our knowledge constrain their wider use. The species are being actively evaluated to increase understanding and inform future deployment.

    Norway spruce (NS)

    Norway spruce is a European native and was present in Britain pre-glacial. As an early reintroduction (before 1550) it was widely planted and is an important forest tree but fell out of favour when the more productive Sitka spruce (Picea sitchensis) became available. More recently the arrival in Britain of the European spruce bark beetle (Ips typographus) poses a distinct threat to both species. However, with active control of Ips, Norway spruce remains a viable alternative to Sitka spruce, particularly on drier sites but not on poor, wet and exposed sites where Sitka is the best choice. Norway spruce is categorised as a Principal tree species. These are tree species where silvicultural knowledge provides confidence to enable successful deployment across Britain. The species are either already widely used or are increasing in usage. They will continue to be important unless affected by a new pest or disease or become adversely affected by climate change.

    Scots pine (SP)

    Scots pine is one of three native conifers but is the only one of commercial importance. An early re-coloniser after the last ice age and considered native in north and west Scotland and colloquially known as the Caledonian pinewoods; they are of significant ecological importance. Elsewhere in Britain it is well suited to many sites where its vigour and robustness make it an important timber species. Scots pine is tolerant of dry conditions which makes this an increasingly valuable species for sites in eastern Britain where drought risk is likely to increase under climate change. Scots pine is categorised as a Principal tree species. These are tree species where silvicultural knowledge provides confidence to enable successful deployment across Britain. The species are either already widely used or are increasing in usage. They will continue to be important unless affected by a new pest or disease or become adversely affected by climate change.
