32 Datganiad Cadwraeth Clawdd OffaOffa's Dyke Conservation Statement 32clawdd, mae goblygiadau cadwraeth ar gyfer ffabrig ygwrthglawdd ei hunan, yn ogystal ag ar gyfer ei leoliad ffisegolehangach. Un mater penodol yw gwarchod llinellau gweld yrhenebyn, fel bod modd parhau i werthfawrogi ei natur unionlin.6.6 Mae’r cysyniad o reoli Clawdd Offa fel rheoli coridorgweledol a hanesyddol cyfun y mae’r ardal HenebynRhestredig yn rhan ddaearyddol fechan yn unig ohono, ynfater yr un mor bwysig. Mae’r broses o gynlluniocadwraeth Mur Hadrian wedi sefydlu gosodiad diffiniediga gwarchodedig ar gyfer yr henebyn (English Heritage1996), ac onid yw’n dilyn ei bod yn briodol ystyrieddatblygu dulliau o drin cadwraeth Clawdd Offa yn yr unmodd.there is a conservation implication not just for the fabric of theearthwork itself, but also for the wider physical setting it sitswithin. A particular issue is to protect sightlines to themonument so that its linear nature can still be appreciated.6.6 The concept of the management of Offa’s Dyke as themanagement of a visually and historically integrated corridorof which the area of the Scheduled Ancient Monument is onlya geographically small part is as an important issue. Theconservation planning process for Hadrian’s Wall hasestablished a defined and protected setting for the monument(English Heritage 1996), and it is surely appropriate to look todevelop approaches to the conservation of Offa’s Dyke in thesame way.Fframweithiau ymchwil archaeolegol6.7 Er ei holl arwyddocâd hanesyddol, nid yw Clawdd Offayn strwythur a ddeallir yn dda yn archaeolegol, gydagastudiaethau ohono yn dangos llawer llai o gynnydd na rhai arhenebyn cymharol megis Mur Hadrian. Mae llawer o waith i’wwneud eto er mwyn esbonio cwestiynau sylfaenol megis maintgwreiddiol y clawdd, ei swyddogaeth a’i ffurf strwythurolfanwl, ei berthynas â gwrthgloddiau tebyg megis Clawdd Wat,a lleoliad unrhyw fynedfeydd gwreiddiol. Yn wir, efallai fodgwerth archaeolegol ychwanegol sylweddol i’r clawdd osafbwynt gwarchod haenau amgylcheddol hynafol nad yw hydyma wedi ei archwilio na’i fesur yn ddigonol. O ben i ben, maeangen arwyddocaol i chwilio am fwy o dystiolaeth sylfaenol,yn ogystal â datblygu yn greadigol prosesau o ddeall adehongli’r deunydd sydd gennym eisoes.6.8 Mae gan yr ansicrwydd archaeolegol hwn oblygiadaupwysig o ran rheolaeth a chyflwyniad dehongliadol y clawdd,ac mae’r angen am ymchwil archaeolegol bellach a dwynynghyd yr hyn sy’n bodoli ar hyn o bryd, yn fater cadwraethpwysig ynghyd â diddordeb academaidd pur.Archaeological research frameworks6.7 For all its historical significance, Offa’s Dyke is not anarchaeologically well understood structure, with its studymuch less advanced than that of a comparable monument likeHadrian’s Wall. A great deal of work remains to be done toclarify fundamental questions such as the original extent ofthe dyke, its function and detailed structural form, itsrelationship to other similar earthworks such as Wat’s Dyke,and the location of any original entrances. Indeed, the dykemay also have a considerable additional archaeological valuein terms of the preservation of ancient environmental depositswhich is as yet little explored or quantified. Overall, there is asignificant need not just to look for more primary evidence,but also to creatively develop processes of understanding andinterpreting the material we already have.6.8 These archaeological uncertainties have importantimplications for the informed management and interpretativepresentation of the dyke, and the need for furtherarchaeological research, and the pulling together of that whichcurrently exists, is a pressing conservation issue as well asone of purely academic interest.Agweddau pragmatig tuag at reolaeth6.9 Mae angen i unrhyw agwedd tuag at ddelio â materioncadwraeth ar Glawdd Offa wynebu’r gwirionedd bod‘achosion’ y niwed i’r gwrthglawdd yn aml yn fynegiant o’runion brosesau a greodd gymeriad nodedig yr henebyn yn ylle cyntaf, ac sydd wedi hwyluso ei oroesiad hyd heddiw.6.10 Er enghraifft, byddai’n amlwg yn gamgymeriadystyried rheolaeth amaethyddol y dirwedd fel un sydd oreidrwydd yn ‘broblem’ i Glawdd Offa; i’r gwrthwyneb,dyma’r brif gyfrwng sydd wedi creu llawer o gymeriad yPragmatic approaches to management6.9 Any treatment of conservation issues on Offa’s Dykeneeds to confront the reality that the ‘causes’ of damage tothe earthwork are often an expression of the very processeswhich created the distinctive character of the monument in thefirst place, and have facilitated its survival to the present day.6.10 For example, it would clearly be quite wrong to project theagricultural management of the landscape as necessarily a‘problem’ for Offa’s Dyke; on the contrary, this is the primaryagency which has created much of the ‘feel’ of the dyke as it
