A Site of Special Scientific Interest (SSSI) in Great Britain or an Area of Special Scientific Interest (ASSI) in the Isle of Man and Northern Ireland is a conservation designation denoting a protected area in the United Kingdom and Isle of Man. SSSI/ASSIs are the basic building block of site-based nature conservation legislation and most other legal nature/geological conservation designations in the United Kingdom are based upon them, including national nature reserves, Ramsar sites, Special Protection Areas, and Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I".

Guildford is a large town in Surrey, England, 27 miles (43 km) southwest of London on the A3 trunk road midway between the capital and Portsmouth.

Surrey is a subdivision of the English region of South East England in the United Kingdom. A historic and ceremonial county, Surrey is also one of the home counties. The county borders Kent to the east, East and West Sussex to the south, Hampshire to the west, Berkshire to the northwest, and Greater London to the northeast.

This is an area of ancient forest on a south facing slope. It has a variety of woodland types due to the geological diversity of the escarpment at different levels. At the bottom is a stream with poorly drained woodland dominated by alder and a ground layer with plants such as marsh marigold and pendulous sedge.^[5]

Alnus glutinosa, the common alder, black alder, European alder or just alder, is a species of tree in the family Betulaceae, native to most of Europe, southwest Asia and northern Africa. It thrives in wet locations where its association with the bacterium Frankia alni enables it to grow in poor quality soils. It is a medium size, short-lived tree growing to a height of up to 30 metres (100 ft). It has short-stalked rounded leaves and separate male and female flower in the form of catkins. The small, rounded fruits are cone-like and the seeds are dispersed by wind and water.

Several public footpaths go through the site.

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
