Biological

Biological SSSI/ASSIs may be selected for various reasons, which for Great Britain is governed by published SSSI Selection Guidelines. Within each area, a representative series of the best examples of each significant natural habitat may be notified, and for rarer habitats all examples may be included. Sites of particular significance for various

Geological

Geological SSSI/ASSIs are selected by a different mechanism to biological ones, with a minimalistic system selecting one site for each geological feature in Great Britain. Academic geological specialists have reviewed geological literature, selecting sites within Great Britain of at least national importance for each of the most important features within each geological topic (or ''block''). Each of these sites is described, with most published in the
Geological Conservation Review The Geological Conservation Review (GCR) is produced by the UK's Joint Nature Conservation Committee and is designed to identify those sites of national and international importance needed to show all the key scientific elements of the geological a ...
series, and so becomes a ''GCR site''. Almost all GCR sites (but no other sites) are subsequently notified as geological SSSIs, except some that coincide with designated biological SSSI management units. A GCR site may contain features from several different topic blocks, for example a site may contain
strata In geology and related fields, a stratum ( : strata) is a layer of rock or sediment characterized by certain lithologic properties or attributes that distinguish it from adjacent layers from which it is separated by visible surfaces known as ei ...

Legal status

Following devolution, legal arrangements for SSSIs (Scotland, England, Wales) and ASSIs (Northern Ireland) differ between the countries of the UK. The Isle of Man ASSI system is a separate entity. NatureScot publishes a summary of the SSSI arrangements for SSSI owners and occupiers (other than public bodies) which can be downloaded from its website. Legal documents for all SSSIs in Scotland are available on the SSSI Register, hosted by The

. The extent to which an SSSI/ASSI may extend seawards differs between countries. In Scotland an SSSI may include the intertidal land down to mean low water spring or to the extent of the local planning authority area, thus only limited areas of estuaries and coastal waters beyond MLWS may be included. In England, Natural England may notify an SSSI over estuarial waters and further adjacent waters in certain circumstances (section 28(1A & 1B) of the Wildlife and Countryside Act 1981 as amended by Part 2 of Annex 13 of the

of the relevant country. Most SSSIs/ASSIs are in private ownership and form parts of working farms, forests and estates. In Scotland, people may use their rights of responsible access to visit SSSIs. When designating an SSSI/ASSI, the relevant nature conservation body must formally notify the interested parties and allow a period for them to make representations before confirming the notification. When creating a new SSSI/ASSI the designation has legal effect from the date of notification. The interested parties include central government, local planning authorities, national park authorities, all the owners and occupiers of the land, relevant public bodies such as the utility providers e.g.,
water companies The water industry provides drinking water and wastewater services (including sewage treatment) to residential, commercial, and industrial sectors of the economy. Typically public utilities operate water supply networks. The water industry doe ...
. In Scotland, NatureScot must also notify the relevant community councils and community group having registered an interest in the land. The notification includes a description of the land and the natural features for which it is notified ("the citation"), a boundary map, and a list of the acts or omissions (activities) that the nature conservation body regulates through the issue of consents.). The various laws protect the interest features of SSSIs from development, from other damage, and (since 2000 in England) also from neglect. Protection is not necessarily absolute—generally it requires the SSSI interest to be considered properly against other factors. Local planning authorities are required to have policies in their
development plan A development plan sets out a local authority's policies and proposals for land use in their area. The term is usually used in the United Kingdom. A Local Plan is one type of development plan. The development plan guides and shapes day-to-day dec ...
s which protect SSSIs. They are then required to consult the appropriate conservation body over planning applications which might affect the interest of an SSSI (such a development might not be within or even close to the SSSI itself). The effect of this is to prevent development which harms the interest – except where the value of that interest is over-ridden by some more important factor, for example a requirement for a major road or port or oil pipe. The requirement for consultation covers any development which might affect the interest, not just developments within the SSSI itself – for example, a development a long way upstream of a
wetland A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils. The ...
SSSI might require consultation. Note that some developments might be neutral or beneficial, even if they are within the SSSI itself – the critical point is whether they harm the interest features. The owners and occupiers of SSSIs are required (Scotland, England, Wales) to obtain consent from the relevant nature conservation body if they want to carry out, cause or permit to be carried out within the SSSI any of the activities listed in the notification. Formerly these activities were called 'potentially damaging operations' or PDOs. Under the current legal arrangements they are called 'operations requiring consent' or ORCs (Scotland), or 'operations likely to damage the SSSI interest' or OLDs (England & Wales). The list of ORCs/OLDs for each SSSI is unique to that site – though all are derived from a standard list for that country. The ORCs/OLDs are not "banned" activities – the list includes activities which would damage the interest, but also many which might be beneficial. For example, "
grazing In agriculture, grazing is a method of animal husbandry whereby domestic livestock are allowed outdoors to roam around and consume wild vegetations in order to convert the otherwise indigestible (by human gut) cellulose within grass and other ...
" (a standard item on the list) would require consent, even on a chalk grassland or heathland where grazing is an essential part of management. In England and Wales the list of OLDs is almost the same for each SSSI – and the list for an SSSI will only omit activities impossible on the particular SSSI (such as fishing where there is no water), and things requiring
planning permission Planning permission or developmental approval refers to the approval needed for construction or expansion (including significant renovation), and sometimes for demolition, in some jurisdictions. It is usually given in the form of a building perm ...
(which are covered by the local planning authority consultation process). In Scotland, and following the implementation of the Nature Conservation (Scotland) Act 2004, Scottish Natural Heritage (the former name for NatureScot) reviewed the ORC lists for each SSSI and removed those activities that were unlikely to happen and if they were to would be unlikely to damage the protected natural features, and other activities adequately regulated by other statutory regimes. The intention of this was to remove the need for owners and occupiers to obtain SSSI consent as well as licences/ permits from other authorities (who must consult NatureScot prior to determining such applications). Purely geological SSSIs often have much shorter OLD lists. If a proposed activity would not affect the interest or is beneficial to it, then the conservation body will issue a "consent" allowing it to be carried out without further consultation. If it would be harmful, the conservation body may issue consent subject to conditions or refuse the application. If consent in writing is not given the operation must not proceed. Conditions may cover any relevant aspect of the proposed operation and may, for example, limit its timing, location or intensity. The process is slightly different where the owner or occupier is a public body, but the effect is broadly similar. The relevant nature conservation body sends all SSSI owners and occupiers a site-specific 'site management statement' describing the ideal management (there may be grants available to help fund management). Owners and occupiers are encouraged to carry out this management, which in many (but not all) cases will be a continuation of the historical management of the land. Where an owner or occupier is unwilling or unable to carry out management, ultimately the conservation body can require it to be done. Public bodies which own or occupy an SSSI have a duty to manage it properly. Site management statements for SSSI in Scotland are available to download from the NatureScot website using the "Sitelink" facility. The law protecting SSSIs now covers everyone, not just public bodies and the owners and occupiers of SSSIs. Previously, activities by "third parties" were not illegal under the SSSI legislation. This meant that damaging activities such as

, intensive bait-digging or trail biking on an SSSI were only prevented if done (or permitted) by the owner or occupier – not if done by trespassers or under public rights. The effect was, for example, to allow control of legal trail biking on SSSIs (where damaging to the interest), but not illegal trail biking. This
