THIS DATA IS A SNAPSHOT AS AT 31ST MARCH 2025 The Register provides information on the availability of surplus land for those government departments and their sponsored bodies which fall under the responsibility of English Ministers. The Register is also used on a voluntary basis by NHS trusts and Welsh Government. The land records are presented as points data. This dataset does not include the land parcel boundaries. The Register helps to ensure that wider Government objectives, including housing needs are factored into land disposal decisions. Through the Register, the disposing body provides details of the site and there is a window of 40 working days during which certain public sector bodies can identify new uses for the land. The dataset available on data.gov.uk covers all sites that are outside the 40 working day ‘window’. Such sites may be included in the disposal strategies that have been published by a number of individual government departments. In addition, these sites may now be ‘on the market’ and being actively marketed. The ‘Register of Public Sector Land’ dataset provides details of any sites that are being disposed of through the Register of Surplus Public Sector Land and are outside the 40 working day ‘window’ Certain properties may have more than one entry in the data extract as government has more than one ‘interest’ in that property. Again, the extract provides information about the ‘owning’ government department and the ‘property centre’, i.e. that part of the government department responsible for that property. In addition, it has a property reference (the ‘ePIMS Property Ref’) that allows it to be linked to the other data extracts. The scope of the data includes land and property information for those government departments, together with any arms’ length bodies for which they are responsible, including their non-departmental public bodies (NDPBs), which fall under the responsibility of English Ministers. These assets are primarily located in England, but are also located in the devolved administrations of Northern Ireland, Scotland and Wales as well as overseas. Also, some Local Authorities have chosen to publish their property data as part of our transparency exercise.

THIS DATA IS A SNAPSHOT AS AT 31ST MARCH 2025 A property is defined as a separate unit, comprising an area of land with or without buildings. The ‘Property’ dataset provides information about the location, size, tenure and type of property. Certain properties may have more than one entry in the data extract as government has more than one ‘interest’ in that property. For example, there may be two leases in the same property. It also provides information about the ‘owning’ government department and the ‘property centre’, i.e. that part of the government department responsible for that property.

THIS DATA IS A SNAPSHOT AS AT 31ST MARCH 2025 Vacant Space is defined as floor space available for occupation either at a holding or occupation level. The ‘Vacant Space’ dataset provides details of any vacant space that is available in buildings occupied by government departments. Certain buildings may have more than one entry in the data extract as government has more than one ‘interest’ in that property.

THIS DATA IS A SNAPSHOT AS AT 31ST MARCH 2025 Basic information about the occupation. A property may consist of a single building or many buildings, associated with one or many holdings. A holding should have at least one occupation record relating to the holding owner. If there is more than one occupier then multiple occupation records may exist. The ‘Occupation’ dataset provides key information about the tenant of each property, the amount of space that they occupy and the nature of that occupation. As certain properties may have more than one tenant, there may be more than one entry in the data extract as government has more than one ‘interest’ in that property. It should be noted that the list of tenants only includes government tenants. It does not include either commercial tenants or tenants from other parts of the public sector.

The Solent system is situated midway along the English channel on the Hampshire and Sussex coasts, and is bounded on its southern side by the Isle of Wight. It includes the Eastern and Western arms of the Solent proper, Spithead, Chichester, Portsmouth and Langstone Harbours, Southampton Water, Newtown Harbour, and the Hamble, Itchen, Test, Beaulieu, Lymington, Afon, Yar, Medina and Wootton estuaries. This represents a total area of approximately 360 km2. The coastline is relatively sheltered from wave action apart from the eastern and western ends of the Isle of Wight, and the shore between gosport and Chichester Harbour which are moderately exposed. The estuaries and harbours are all very sheltered. A complex tidal regime in the region results from the system having two entrances to the Engish Channel some 35 km apart. The tidal curve varies in shape between the eastern and western entrances, and also btween spring and neap tides. In general, there is a prolonged stand at high water followed by a shortened ebb flow, and a stand also occurs during the flood phase. The mean tidal range varies between 1.5m at the western entrance to 3m at the eastern end. The unusual tides, coupled with the configuration of the Solent, results in fast tidal currents, especially on the ebb. Currents are quickest in the constricted Hurst Narrows, and in the comparatively narrow entrances to the three large eastern harbours. Salinity is reduced and variable in all the estuaries and inlets bordering the Solent. The salinity of the central region of the Solent proper is also slightly reduced in comparison to its outer ends, although mean surface salinity is always above 34'/00. Benthic habitats are predominently sedimentary in nature with extensive intertidal mud and sand flats, and areas of gravelly and pebbly sediments. Hard substrata are limited to the relatively small limestone outcrops on the Isle of Wight, dock walls and other man made structures in the harbours and dock areas, and to cobbles and pebbles overlying the muddy sediments. Subtidally, benthic habitats are also sedimentary, and range from silty mud in the more sheltered inlets to tidally swept stones, shells and coarse sand in the main body of the Solent. Southampton and Portsmouth are centres of industry and international shipping, and this part of the coast is also densely populated and urbanised. Major petro-chemical industries, including an oil refinery, are sited on Southampton Water and the latter is served by an ocean terminal that can accomodate tankers of over 200,000 tons displacement. The coastline to the west, backed by the New Forest, and the Isle of Wight are still comparitively rural in character. Other major uses of the Solent system are in the fishing and recreation industries. The Solent and adjacent areas of the English Channel are nationally important fishing grounds for demersal fish, mackerel, bass, crustaceans and molluscs. The most important shellfisheries are for the native oyster, Ostrea edulis, and for the introduced clam species, Mercenaria mercenaria. The area is used intensively for recreation which includes all the persuits normally carried out in populus coastal areas, but with a special emphasis on yacht racing and cruising. The area has long been of scientific interest, both biologically and physiographically, and is currently used for both educational and research purposes. The importance of the extensive mudflats and marshes in botanical and ornithological terms, is well recognised and is detailed in the 21 SSSI designations in the region. Although mainly unspecified, the marine biological resources of these sites are important as an integral part of the environment. The designation for the Bembridge Ledges SSSI, however, acknowledges the scientific interest of the diverse algal populations and also the fact that the Solent lies more or less on a physical and biogeographic discontinuity separating the English Channel into distinct eastern and western basins. The Solent system is also of marine biological interest in that it is a focal point for the introduction and subsequent spread of alien species to the British Isles. The present survey, carried out in July, 1986, aimed to collect information on the variety of habitats and communities present subtidally in the West Solent, together with similar information for the few rocky intertidal areas on the north coast of the Isle of Wight. No Man's Land Fort in Spithead was also studied. Little published data exists for these areas in comparison with the remainder of the Solent system. A total of 35 sites were sampled of which 31 were subtidal. At each site, the abundance of epiflora, epifauna and conspicuous infaunal species was recorded in situ. Subtidal sites were sampled using a combination of trawling, dredging and diving techniques. Dredge samples were sieved over a 1.0mm mesh to obtain specimens of infauna. During the survey, a total of four intertidal and nine subtidal habitats were distinguished. Epifaunal and algal diversity was generally low, for reasons which probably included scarcity of stable hard substrata, strong tidal currents and turbidity. All rocky shores were algal dominated, mainly by fucoids and Audouinella sp. The most widespread conspicuous animals species were Semibalanus balanoides and Littorina littorea although population levels at any one site were generally low. In the sublittoral, algae typical of the extensive shallow stony sediments included Griffithsia floculosa, Hypoglossum woodwardii, Gracilaria verrucosa, Polysiphonia nigrescens, Sargassum muticum, and brown filamentous and red encrusting species. Diversity was highest on shallow boulder habitats and on No Man's Land Fort. Most of the sessile or encrusting epifaunal species were ubiquitous, and were characterised by Balanus crenatus, Pomatoceros spp., Dendrodoa grossularia and Halichondria panicea. The slipper limpet, Crepidula fornicata, was dominent on sediments everywhere apart from mobile sand. Tubularia indivisa and Halichondria panicea dominated on stable boulders subjected to the fastest currents. The diversity of epifauna and conspicuous infauna was highest in Stanswood Bay. Infaunal communities of the West Solent were polycheate dominated, and of low diversity and density. The main characteristics of the communities found do notappear to have changed significantly over the last fifteen years. There is no data available against which to judge the degree of change attributable to the spread of Crepidula fornicata in the earlier half of this century. The scientific interest and nature conservation importance of the Solent system has been assessed using standard criteria and the conservation importance provisionally graded as of Regional, National or International importance. Habitats and species not encountered during the relatively limited survey work have been assessed on the basis of published and unpublished data, and on information gained locally through interviews and correspondance. Much of the Solent's intertidal area is well recognised of being of importance for botanical and ornithological reasons. The marina fauna and flora are thus afforded protection through these interests but should, in addition, be recognised for their own scientific interest and as a facet of the ecology of the region. Most of the species assessed as being of conservation importance are recent introductions to the British flora and fauna, and may require reassessment in the light of any future distributional expansion, as was shown by Sargassm muticum for instance. Threats to the conservation interests within the Solent system include unnecessary loss of intertidal habitat through reclamation works, industrial and domestic pollution (particulary in the larger enclosed harbours), the effects of organotin antifouling compounds used on ships and yachts, bait digging and the development of nearshore oil production facilities. Records currently considered sensitive have been removed from this dataset.

Six mainland lochs south of Oban were surveyed during 1989 as part of the survey of Scottish sealochs. Loch Feochan, the most northerly, opens into the Firth of Lorne and is protected from the west by Mull, but has a broad exposure gradient. It lies in a lava plateau and is fiordic with two shallow sills and deep basins. The remaining five lochs, Melfort, Craignish, Crinan, Caolisport and West Loch Tarbert, are situated on the Sound of Jura in an area of Dalradian rocks and are sheltered by the Jura-Islay chain of islands. They are all oriented NE-SW apart from Loch Crinan which faces NW. Loch Craiginish is the most complex, with two sheltered lateral arms and five sills. The main body of the loch is filled with shallow sediments but there are depths of 100m at the entrance in an area of strong tidal streams. Loch Crinan shares this entrance but has no sill; it is shallow with a steep bank at its entrance and estuarine sediments at the head. Loch Melfort has a limited exposure gradient, one sill, a basin reaching 73m and depths of 30-40m throughout. West Loch Tarbert has a single sill but is predominantly shallower than 10 m. Loch Caolisport, with no sill, is moderately exposed at its head. Tidal ranges in West Loch Tarbert are amongst the smallest in the British Isles whilst those in Loch Feochan are more typical of the Scottish west coast; strong tidal streams running through the complex of offshore islands are one of the dominating features of the region. The area as a whole has a limited exposure gradient with nowhere more than moderately exposed, a limited range of sublittoral sediments and a moderate range of rocky substrata. There is a considerable amount of boat traffic through the Crinan Canal and yachting is an important activity. All of the lochs apart from Crinan have salmon and shellfish farms but there is no other industry. There are two MCA's, one pMNR (Loch Sween) and several SSSIs in the area. Much littoral work has been carried out in the area, most noticably by Lewis (1957) and Lewis and Powell (1960a,b) but there have been few sublittoral studies. Sixty-two sites were surveyed of which 4 were littoral and 58 were sublittoral; 26 habitat/community types were described. Infralittoral bedrock communities ranged from rich Laminaria hyperborea forests in the tide exposed areas, through mixed forests of L.hyperborea and Laminaria saccharina to L.saccharina and Chorda filum in the most sheltered regions. Sheltered circalittoral rock in upper Loch Feochan supported the anemone Edwardsiella carnea where as in Loch Melfort brittlestar aggregations dominated the rock surfaces and reduced the diversity. This was the only loch where Protanthea simplex was found. Excellent examples of tide-swept rock communities were present in the Craignidh-Crinan area, supporting a great variety of species including Swiftia pallida, sponges, ascidians, brachiopods and echinoderms. Several communities were represented in a small area and an unusually large number of interesting species were found. The sills in Loch Feochan and West Loch Tarbert also supported diverse communities exposed to tidal streams. Sediments were less varied and were primarily muddy. Three main community variants were described, these being dominated by Virgularia mirabilis, Cerianthus lloydii and burrowing brittle stars. Coarser, moderately exposed sediments held a wide range of algal species. Deep soft mud inhabited by Nephrops norvegicus was found in Loch Melfort, but Funiculina quadrangularis, often found in similar habitats, was not recorded. Shallow muds in the heads of the lochs supported Philine aperta; this habitat extended over 9km in West Loch Tarbert. Seven habitat/community types and twenty-three species have been provisionally assessed to be of Regional or International importance. Records currently considered sensitive have been removed from this dataset.

Loch Sween is situated on the east side of the Sound of Jura, in south-west Scotland. It opens to the south-west and its mouth is partially protected by the small MacCormaig Isles. The main body of the loch is relatively straight, with a fringe of rocks or gravel giving way to a sandy or muddy seabed. There are a number of arms to the loch which add considerably to the diversity of habitats present. Linne Mhuirich forms an arm to the west, with a constricted mouth into Loch Sween forming an area of tidal rapids. At the head of the loch, arms include the silled Caol Scotnish. Adjacent to Loch Sween, once connected to it but now separated by causeway, is Loch na Cille. Loch Sween has been proposed as a Marine Nature Reserve by NCC on account of the high scientific interest and conservation importance of the habitats and communities within the loch. Although a site of historical marine biological recording and research, NCC commissioned extensive systematic littoral and sublittoral surveys in 1982. Further information was required on the distribution and types of littoral habitats and communities present to assess the relative importances of individual areas and the integrated importance of the whole loch. The aims of the shore surveys in 1985 were; to investigate the shores around Ceann an t-Sailein; to assess any temporal variation in faunal communities, particularly molluscan, in the Linne Mhuirich area; and to describe the shores of Loch na Cille. Survey work was carried out during spring and autumn visits. Descriptions of all the sites are included in the report, which also contains a detailed species list and tables showing the numbers of Mollusca associated with algae. The discussion is limited to a summary of the more important information found during the spring surveys. The report concludes that Ceann an t-Sailein adds another habitat type (a shallow tidal bay with a clay floor) to those already known in Loch Sween. Several community types were recorded from the sediment shores. Further variability in molluscan populations was noted but showed no clear pattern which could be related to seasonality. Several mollusc species new to Loch Sween were recorded. Records currently considered sensitive have been removed from this dataset.
