Description

The citation for the SSSI says:

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.^[1]

History

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.

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".^[2]
