SSSI selection and conservation


Sites notified for their biological interest are known as Biological SSSIs, and those notified for geological or physiographic interest are Geological SSSIs. SSSIs may be divided into management units, with some SSSI areas including units that are notified for both biological and geological interest.

Biological SSSIs


Biological SSSIs may be selected for various reasons, 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 taxonomic groups may be selected (for example bird

Geological SSSIs


Geological SSSIs are selected by a different mechanism to biological SSSIs, 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

 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

Geological SSSIs fall into two types, having different conservation priorities:

Exposure sites

Deposit sites


These are features which are limited in extent or physically delicate—for example, they include small lenses

—but not the sea below Mean Low Water.

SSSIs are not necessarily open to the public, nor are they necessarily owned by a conservation organisation or by the British government—in fact, their access and ownership are no different from the rest of the countryside.

The formal notification of SSSIs is made to a number of different people: central government, local planning authorities

.

The notification includes a description of the interest (citation), a map of the boundary, and a list of activities requiring consultation (see below).

The law protects the interest features of SSSIs from development, from other damage, and (since 2000) also from neglect. Protection is not necessarily absolute—generally it requires the SSSI interest to be considered properly against other factors.

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
Road
A road is a thoroughfare, route, or way on land between two places, which typically has been paved or otherwise improved to allow travel by some conveyance, including a horse, cart, or motor vehicle. Roads consist of one, or sometimes two, roadways each with one or more lanes and also any...

 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
Wetland

 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 to consult the appropriate conservation body if they want to carry out (or permit) activities on the land. Activities requiring consultation are listed in the notification, and are called Potentially Damaging Operations (PDOs), or more correctly Operations Likely to Damage the SSSI interest (OLDs) (in Scotland these are known as Operations Requiring Consent - ORCs). In practice, there is a standard list of OLDs which is almost the same for each SSSI—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

 (which are covered by the local planning authority consultation process). Purely geological SSSIs often have much shorter OLD lists. The OLDs are not "banned" activities—the list includes activities which would damage the interest, but also many which might be beneficial. For example, "grazing
Grazing
Grazing generally describes a type of feeding, in which a herbivore feeds on plants , and also on other multicellular autotrophs...

" (a standard item on the list) would require consultation, even on a chalk grassland or heathland where grazing is an essential part of management.

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, consent cannot be issued, and the activity must not be carried out. Sometimes a consent will be issued with conditions, for example limiting the timing, location or intensity of an activity. The process is slightly different where the owner or occupier is a public body, but the effect is broadly similar.

The appropriate conservation body sends all SSSI owners and occupiers a statement of what the ideal management should be (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.

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 fly-tipping

, 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 loophole

New SSSIs


The process of designating a site as a Special Scientific Interest is called notification; this is followed by consultation with the site's owners and occupiers, and the notification is then confirmed or withdrawn (in whole or part).

Renotification


At the time of the passing of the Wildlife and Countryside Act in 1981 many SSSIs were already in existence, having been notified over the previous decades under the National Parks and Access to the Countryside Act 1949. Each of these was considered in turn, and either denotified, or renotified—brought under the provisions of the new Act, often with boundary changes. This complex process took some ten years to complete for the several thousand SSSIs.

Areas of Search


For the purposes of selecting candidate SSSIs, Natural England and its predecessors use a system termed "Areas of Search" (AOSs). In England these are largely based on the 1974-1996 administrative counties
Metropolitan and non-metropolitan counties of England
