Wood-Pasture and Parks It is only relatively recently that lowland wood-pasture as a habitat type has been recognised. It is, by its simplest definition, an area of land where the growing of trees was combined with the grazing of animals. Included under this definition are wooded commons, ancient royal forests, chases and parks. The trees within a wood-pasture are characteristically pollards - trees cut at a height which would prevent livestock from browsing the re-growth. Parks stocked with deer in the medieval period differed from forests, in having a deer-proof perimeter fence - the pale - were privately owned and were not governed by a legal system or special administration. Hylands came late to this group. It was created in the early 18th century from a pre-existing agricultural landscape, as were many much earlier parks. Characteristically Hylands was surrounded by an oak pale; animals including cattle and sheep were grazed here and today a large herd of fallow deer (around a hundred head) roam the park, although the perimeter fence is no longer deer-proof. Pollard trees are present in the park, albeit in small numbers (and all are of hedgerow origin). As a park created for its visual amenity, rather than as a producer of venison, standard trees - including a number of sizeable oaks - are in the majority. Hylands is not of medieval origin, although it does incorporate elements of ancient landscapes within its current boundary. The Great Oak on Writtle Hills - possibly more than 500 years old - probably started life in the 15th or 16th century. Hylands is relatively young, at about 270 years old (in part). Parks such as this are sometimes termed 'pseudo-medieval', but there is no real justification for this term, since many medieval parks were created in this way as well and we don't refer to medieval parks as being 'pseudo-Saxon'. In 1320 Edward I gave leave ''to inclose 150 acres of demesne adjoining park of Waltham and High Easter called Le Plessie to enlarge that Park". The resulting enlarged Pleshey Great Park, comprising some 625 acres of coppiced woodland, hedgerows, trees and pasture, is little different in structure to the 570 acres of Hylands Park today. Even now. what is Britain's best studied deer park - Moccas Park in Herefordshire - (famous for its rare beetles and now a national nature reserve) may not be medieval in origin. There appears to be no record of a licence to empark (possibly one was not applied for) and the park is first recorded in the early 17th century. In 1617 some deer were sent from Moccas to stock a park in Ireland. The Lower Park at Moccas has ridge and furrow (probably medieval) and according to John Phibbs - ''Most of the veteran oaks stand on the ridge and furrow". Its most famous tree - the "Hypebaeus Tree" (named for a rare beetle only known in Britain from Moccas) - a very ancient oak pollard "appears to be in origin, a hedgerow tree". So Moccas in fact may be a 'pseudo-medieval' park created in part out of agricultural land that had gone out of cultivation much earlier, possibly during the 'BlackDeath'. The vast Richmond Park in Surrey, twice the size of Hatfield Forest and another National Nature Reserve, was emparked as late as 1637 by Charles I as a place to hunt red deer - hence its size. It too consisted of existing farmland, but also common land and woodland (relatively little Crown land was involved in its creation). Parks have been created virtually throughout England's history since the Conquest and still goes on today in the form of 'country parks', which are emparked for their wild-life and public amenity, not for their deer. At all times there has been an ebb and flow of park creation - thousands were made in the medieval period, hundreds disparked in the 17th and 18th centuries. A feature of Essex parks is that they were created and adapted from a pre-existing, sometimes agricultural, landscape of woodland, fields and pastures. Essex Parks: Section 1 - Parks in Essex 53
