Trodds Copse (grid reference) is a 25.23 hectare biological Site of Special Scientific Interest (SSSI), in central Hampshire, notified in 1989. It comprises ancient semi-natural woodland, unimproved meadows and flushes.
The Ordnance Survey National Grid reference system is a system of geographic grid references used in Great Britain, distinct from latitude and longitude. It is often called British National Grid (BNG).
The hectare is an SI accepted metric system unit of area equal to a square with 100-metre sides, or 10,000 m2, and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about 0.405 hectare and one hectare contains about 2.47 acres.
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".
The copse is situated to the north-west of Chandler's Ford between Flexford Road and Hook Road and adjoins the Eastleigh to Romsey railway line.
Chandler's Ford (originally The Ford and historically Chandlersford is a largely residential area and civil parish in the Borough of Eastleigh in Hampshire, England, with a population of 21,436 in the 2011 UK Census.

Trodds Copse Site of Special Scientific Interest comprises ancient semi-natural woodland, unimproved meadows and flushes overlying Bracklesham Beds, Bagshot Sand, peat and alluvium. The habitats are drained by tributaries of the Monks Brook, a branch of the River Itchen. The diverse geology and varied drainage conditions give rise to a wide range of habitats. At least ten woodland types can be identified, of which four are considered nationally rare. The diversity of woodland types is matched by an extremely rich ground flora. The antiquity of the woodlands is reflected in the very high number of ancient woodland indicator species recorded within the site. Over fifty such species occur, including a number of rare or local plants such as tutsan ( Hypericum androsaemum ) making it one of the botanically richest woods in Hampshire.
In geology, the Bagshot Beds are a series of sands and clays of shallow-water origin, some being fresh-water, some marine. They belong to the upper Eocene formation of the London and Hampshire basins, in England and derive their name from Bagshot Heath in Surrey. They are also well developed in Hampshire, Berkshire and the Isle of Wight. The following divisions are generally accepted:
Peat, also known as turf, is an accumulation of partially decayed vegetation or organic matter. It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. The peatland ecosystem is the most efficient carbon sink on the planet, because peatland plants capture CO2 naturally released from the peat, maintaining an equilibrium. In natural peatlands, the "annual rate of biomass production is greater than the rate of decomposition", but it takes "thousands of years for peatlands to develop the deposits of 1.5 to 2.3 m [4.9 to 7.5 ft], which is the average depth of the boreal [northern] peatlands". Sphagnum moss, also called peat moss, is one of the most common components in peat, although many other plants can contribute. The biological features of Sphagnum mosses act to create a habitat aiding peat formation, a phenomenon termed 'habitat manipulation'. Soils consisting primarily of peat are known as histosols. Peat forms in wetland conditions, where flooding or stagnant water obstructs the flow of oxygen from the atmosphere, slowing the rate of decomposition.
Alluvium is loose, unconsolidated soil or sediment that has been eroded, reshaped by water in some form, and redeposited in a non-marine setting. Alluvium is typically made up of a variety of materials, including fine particles of silt and clay and larger particles of sand and gravel. When this loose alluvial material is deposited or cemented into a lithological unit, or lithified, it is called an alluvial deposit.
Trodds Copse and surrounding land has been well documented since the late 16th century. The whole site was enclosed from common land prior to 1588 and woodland boundary banks can be clearly discerned. Some areas were managed as wood pasture but by the early 19th century this practice had ceased, the land being converted to pasture or coppice woodland.
Pasture is land used for grazing. Pasture lands in the narrow sense are enclosed tracts of farmland, grazed by domesticated livestock, such as horses, cattle, sheep, or swine. The vegetation of tended pasture, forage, consists mainly of grasses, with an interspersion of legumes and other forbs. Pasture is typically grazed throughout the summer, in contrast to meadow which is ungrazed or used for grazing only after being mown to make hay for animal fodder. Pasture in a wider sense additionally includes rangelands, other unenclosed pastoral systems, and land types used by wild animals for grazing or browsing.
The site is threatened by the north-westerly expansion of Chandler's Ford. In 1990, a planning application to build 200 houses and a golf course at neighbouring Broadgate Farm, Ampfield was refused as it "would result in the destruction of part of the Trodds Copse Countryside Heritage Site".
Ampfield is a village and civil parish in the Borough of Test Valley in Hampshire, England, between Romsey, Eastleigh, and Winchester. It had a population at the 2001 census of 1,474, increasing to 1,583 at the 2011 Census.
Among the many tree and plant species found at Trodds Copse are:
The wide range of habitats is reflected by the diverse invertebrate fauna present within the site, including:
Gordano is an area of North Somerset, in England. It has been designated as a National Nature Reserve.
Yanal Bog is a 1.6 hectare biological Site of Special Scientific Interest on the southern edge of the North Somerset Levels, just north of the village of Sandford, North Somerset. It was notified as an SSSI in 1988.
Lambert's Castle is an Iron Age hill fort in the county of Dorset in southwest England. Since 1981 it has been designated as a Site of Special Scientific Interest (SSSI) on account of its geology, archaeology and ecology.
Scotstown Moor is in the north of Aberdeen, Scotland.
Purple moor grass and rush pastures is a type of Biodiversity Action Plan habitat in the UK. It occurs on poorly drained neutral and acidic soils of the lowlands and upland fringe. It is found in the South West of England, especially in Devon.

Cefn Blaenau is a 23-hectare Site of Special Scientific Interest in a small upland valley in Carmarthen & Dinefwr, Wales. It was designated an SSSI in 1989 primarily for its flush and spring vegetation as well as the diverse mosaic of unimproved pasture, ‘ffridd’ land, marshy grassland, wet heath, acid grassland, broadleaved woodland, streams, and small rock outcrops. These habitats, which are well represented at this site, have been greatly reduced in north Carmarthenshire due to land improvement, agricultural intensification, and afforestation. Only about 140 hectares of flush and spring vegetation remain in the county.

The moors are asserted to be of national importance by Natural England for the extent, quality and diversity of upland types including heaths, fens, wet grassland, flushes, mires and blanket bogs, together creating an extensive mosaic habitat supporting an exceptional community of amphibians. The moors are important, too, for their relict juniper woodland and scrub.
