Regions of Provenance (0)

Regions of Provenance Great Britain is divided into four Regions of Provenance.$FILE/FRMGuidelinesRoPmap.pdf These are defined areas within which similar ecological and climatic characteristics are found. They provide a framework for specifying sources of Forest Reproductive Material (FRM). For native species, these Regions of Provenance have been split into a total of 24 non-statutory native seed zones. Seed zones are in turn divided where appropriate into two altitude zones, below 300m and above 300m. There is a different set of seed zones for native Scots Pine. Definitions of Origin and Provenance The origin of FRM describes that part of the natural range of the species from which the material originally derived. The term provenance is used to describe the location of the source from which the reproductive material was collected.

Pinewood Zone (1)

Pinewood Zone - The pinewood zone is the area within Scotland where Scots pine - pinus sylvestris is deemed a native species; outside of this zone it is believed that pine is not native.

Caledonian Pinewoods (4)

Caledonian Pinewoods Description: Scots pine (Pinus sylvestris L.) has the largest natural distribution of any conifer in the world, ranging from northern Norway to Spain, and from Scotland across Europe and Asia to Siberia and north-east China. It can grow on a range of soil types, surviving where the rainfall is as low as 200mm, and/or where the temperature drops to -64 degrees C. In Scotland, pines were an important component of post-glacial natural forests (the so-called Wood of Caledon) which covered an estimated 70% of the country. They were largely confined to the poorest soils, often occurring in association with birch, but they also grew in mixture with other species in natural transitions to oak, ash and elm dominated woodland on the better soils, and to willows and alder on wet areas. Over many centuries vast areas of these ancient forests were cleared, and pinewood regeneration was prevented, either by allowing the land to be grazed or by replanting it with other tree species, usually of non-native origin. Other adverse effects were the browsing of deer and 'muirburning' to improve the grazing or the age structure of heather on adjacent grouse moors. Pinewoods vary enormously in size, structure and natural species diversity. In Deeside, Strathspey and the Beauly catchment the pine-dominated woodlands are relatively extensive, but in Glen Falloch and Glen Loyne there are only a few old trees scattered over a large area. Other pinewoods occur on steep cliff faces, or in gorge woodlands, such as at Glen Avon, Allt Chaorunn and Attadale, where there may be several age classes present. The wet western pinewoods are more fragmented and isolated than most, and are generally regarded as being in the poorest condition, occasionally merging with oak, alder and other woodland types, indicating that there is scope for re-creating large new mixed native forests in those areas. There are also biochemical differences between pinewoods; these are indicative of genetic variation. Of the seven Regions of biochemical similarity identified, the North West Biochemical Region, near Kinlochewe, is the most distinct, exhibiting considerable differences between individual pinewoods. It is known from the analysis of pollen records taken from peat bogs that pine has been present in North West Scotland for at least 8500 years, but when combined with the genetic information one may begin to speculate that the pines we see now are the direct descendants of trees which survived the last ice age either in Ireland, or possibly on areas of the continental shelf exposed by the lowered sea levels at that time. The pinewoods of the South West Biochemical Region, around Fort William, are another distinct group. They show less variation between the fragments, although it is believed that they had a similar history to those in the North West Biochemical Region. The biochemical characteristics of the other pinewoods in Scotland are not so dissimilar, and these pinewoods seem to have more in common with Central Europe pinewoods. In 1959 Steven and Carlisle published their book 'The Native Pinewoods of Scotland', in which they listed and described most of what they regarded as surviving (ex-Caledonian Forest ) pinewoods. This stimulated an interest in pinewood conservation, and in due course the introduction of a number of incentives to support pinewood management and expansion. More recently the native pinewoods of Scotland have been listed as an endangered habitat in the EC Habitats Directive. They are also the subject of a costed Habitat Action Plan (prepared under the UK Biodiversity Plan) which gives quantitative targets for the protection, restoration and expansion of the pinewoods by both natural regeneration and replanting. These targets are based on an earlier version of this Inventory. ----------------------------------------------------------------------------------------------------------------------------- To prepare the Caledonian Pinewood Inventory, the current extent of the native pinewoods named by Steven and Carlisle, have been investigated. Some of the pinewood fragments which they thought were too small to form discreet pinewood habitats, have also been considered. The total pinewood area now included in the Inventory is nearly 18000 hectares, and comprises 84 separate pinewoods of various sizes. In all cases the balance of probability suggests that they are genuinely native, that is, descended from one generation to another by natural seeding. In addition, each pinewood has: • a minimum density of 4 pine trees per hectare, excluding trees less than 2 metres in height, or at least 50 pine trees per hectare where sites have been extensively underplanted but are deemed capable of restoration to a more natural state; • a minimum of 30 individual trees, unless the wood has historical, aethetic or biological significance; • vegetation which is characteristic of native pinewood, although possibly of a depleted diversity; • a semi-natural soil profile, but accepting also sites with superficial cultivation such as shallow ploughing or scarification with some widely spaced drains. -------------------------------------------------------------------------------------------------------------------------- Inventory Rules: PINEWOOD FRAGMENT Recorded separately if more than 1.5km from another fragment. REGENERATION ZONE Standard 100m but more if conditions indicate spread is likely to be greater (e.g. Glen Tanar). Where regeneration is likely to be less, such as a fragment of pine in an oakwood, then a smaller regeneration zone may be indicated (e.g. Loch Maree Islands). Area does not normally include open water unless the whole of the open water is within the pinewood and regeneration zone. BUFFER ZONE Standard 500m beyond regeneration zone but can be extended further:- 500m beyond watershed or 700m above sea level (e.g. Gleann Fuar) link fragments together (e.g. Barisdale) Buffer zones will not include extensive areas of open water (e.g. South Loch Arkaig) unless the whole of the open water is within the buffer zone. Where the buffer zone includes some ground on the other shore of a loch then the water will be part of the buffer zone (e.g. Loch Hourn). PLANTED AREAS If of correct local origin then accept as pinewood if less than a third of total area of pinewood. The planted areas would be hatched on the maps and recorded as part of the regeneration zone not as part of the pinewood. Planted areas of correct origin, which are alongside pinewood, can have the regeneration zone round them (e.g. Doire Darach). Where a planted area has just been planted or is to be planted and is more than a third of the area of the pinewood, then it may be considered as part of the buffer zone and the buffer zone may be extended to 500m beyond the planted area (e.g. Breda). Planted areas of local origin which are more than 500m from the pinewood will be ignored.

Forest Reproductive Material Sites (5)

Forest Reproductive Material Sites Forest Reproductive Material (FRM) is the generic name for the seeds, cones, cuttings and planting stock used in forest establishment. The 46 tree species and the genus Populus (including aspen, black poplar and grey poplar) covered by the Regulations are known as the “controlled species”. The Forest Reproductive Material (Great Britain) Regulations 2002 regulate the marketing of FRM. These Regulations came into force on 1st January 2003 and implement EC Directive 1999/105. The Forestry Commission is the Official Body that is responsible for the FRM Regulations in England, Scotland and Wales. The Forestry Commission maintains the National Register of Approved Basic Material for Great Britain (The National Register). Each entry of basic material (or unit of approval) in the National Register is given a unique register reference that encodes: Species name Type of basic material Category of reproductive material to be produced Region of provenance Native seed zone (where appropriate) Altitude zone (if the species is native to GB) Origin (that part of the species’ natural range from which the material derives). The attributes of each polygon in this dataset are restricted to the National Register Identification Number (NRID), a national grid reference (NGR), a Basic Material 'category' symbol and the land area, in hectares. All other details mentioned above are available in the National Register. Basic Material is the plant material from which the Forest Reproductive Material (FRM) is derived and includes seed stands, seed orchards, parent material held by tree breeders in archives, individual clones and mixtures of clones. There are six types of basic material: Seed sources: This covers all material from a single tree to any collection of trees within a region of provenance or seed zone. Stands: Specifically identified areas or groups of trees with identified boundaries . Seed orchards: Sources based upon known individuals derived from tree breeding. Parents of families: Sources based upon known individuals derived from tree breeding. Clones: Individually identified trees from which the FRM will be produced through vegetative propagation . Clonal mixtures: Individually identified trees from which the FRM will be produced through vegetative propagation. Forest Reproductive Material (FRM) is cones, fruits and seeds, all parts of plants obtained by vegetative propagation, including embryos and plants produced from any of these. Normally, only FRM that comes from registered basic material can be marketed. There are four categories of reproductive material according to the basic material from which it is collected and these are recorded in this dataset: Source identified FRM (symbol SI): Comes from general or specific locations within a single region of provenance or seed zone altitude band in which no specific superior qualities are recognised. Selected FRM (symbol SE): Collected from stands showing superior characteristics, e.g. better form, growth rate and health. Qualified FRM (symbol QU): Derives from the selection of superior individual trees which have not undergone any form of testing. Tested FRM (symbol TE): Derives from the selection of individual trees or stands that have undergone evaluation for genetic quality or have been shown to be superior, in comparison to accepted standards.

Native Woodland - Integrated Habitat Network (6)

Native Woodland - Integrated Habitat Network This dataset provides an Integrated Habitat Network (IHN) for native woodlands in Scotland. Its purpose is to aid the scoring process when assessing Forestry Grant Scheme (FGS) applications made under the SRDP (2014-2020) programme. It identifies three levels of information:- - core native woodlands - primary zones that are within a 'least-cost distance' of 500m - secondary zones that are within a 'least-cost distance' of 2,000m These latter two zones represent the differing dispersal abilities of generic woodland species across surrounding land which is not source native woodland.

Forest Research Experiment Sites (7)

Forest Research Experiment sites This dataset records Forest Research Experiment sites on the National Forest Estate and private land. Objective is to avoid accidental damage to Forest Research experiments and sample plots during Forest Enterprise operations and to provide Forest Enterprise Districts with contact details for experiments and sample plots so that they can enquire as to suitability of operations in surrounding forest.
