A survey of hedgerows in the parish of Ingatestone and Fryerning in Stock Lane - which stands at around the 40 m contour- and the Woolpack public house at the top of Fryerning Lane, which is close to 95 m. the maximum height above sea level in the parish. Unless you are fit you'll probably need a drink by the time you get there! If you fancy a pub crawl, then it's fairly flat going along the top of the ridge to, firstly, The Cricketers, then The Viper, where the land falls away again. The map depicting the surface geology of Essex printed in Jermyn (1974) was partly based on old series geology maps dating back to the early 19th century but, fortunately, most of Ingatestone & Fryerning was covered by updated information that became available just prior to publication. This clearly shows that the parish lies on the boundary between the London Clay to the south and the more recent (in geological terms) Chalky Boulder Clay to the north and west. Basically, the tops of the Fryerning-Mill Green ridge are capped with acidic Bagshot Pebble and Gravel Beds, below which lie an extensive area of Bagshot Sands. As the land descends, these merge with the Claygate Beds and finally with the London Clay, the latter of which contains areas of mixed soils, known as Head, close to the River Wid. The map also depicts a few small pockets of Chalky Boulder Clay close to the surface. These are most evident where the soil has been disturbed, such as at Handley Barns, where the recent construction of a fishery revealed a considerable area of calcareous material. As, however, the majority of parish soils are neutral to acidic, this obviously influences the species composition of the hedgerows. Shrubs like Buckthorn Rhamnus cathartica, Guelder Rose Viburnum opulus and Wych Elm Ulmus glabra - which are often common in hedgerows a few miles to the north and west - are rare or unknown locally while both Spindle Euonymus europaeus and Dogwood Cornus sanguinea arc commonest on farms where the pockets of boulder clay occur. The evolution of the parish landscape: 1600-2000 As Oliver Rackham and other authors have pointed out, several misconceptions regarding the evolution of the farmland landscape in eastern England have gained credence at one time or another in recent years. One of the most persuasive - often propounded by irresponsible landowners - was that even the oldest hedges in this part of the country were planted during the half century following the Enclosure Acts of the late 18th century, and many much later than this (Rackham 1980, p.26). Thanks to the works of Rackham it is now well known that this is true only of one half of lowland England; the other, dubbed by Rackham as Ancient Countryside was enclosed many centuries before, and is "the England of hamlets, medieval farms in hollows in the hills, lonely moats and great barns in the clay- lands, pollards and ancient trees, cavernous holloways and many footpaths, fords, irregularly shaped groves with thick hedges colourful with maple, dogwood and spindle - an intricate land of mystery and surprise" (Rackham 1980, p.4). Its landscape often dates back to Saxon times, if not earlier. Ingatestone & Fryerning sits firmly in the middle of that ancient countryside and still retains many of the features that signify a thousand or more years of historical continuity. Another misconception was that the destruction of so many hedgerows and other historical features of the landscape since 1950 was unavoidable, as the countryside had always been changing in the light of agricultural improvements, and the current changes were no different. That has an element of truth to it, of course, but overlooks the fact that some of the most destructive periods in the past were associated with agricultural protectionism, as they are now. In particular, the widespread grubbing out of ancient woodland and hedgerows in the first half of the nineteenth century was directly connected to the failure by politicians to repeal the Corn Laws, following the Napoleonic Wars. Which resulted in the price of wheat remaining at an artificially high level, despite a downturn in agriculture as a whole. The evidence is that, as Rackham (1980 p.26) states, changes have happened at some times and in some places but not others. This is certainly the case in Ingatestone and Fryerning, where changes between 1600 and 1950 tended to be piecemeal rather than wholesale. 156 Essex Naturalist (New Series) 21 (2004)
