Mae’n golygu delio gyda nodweddgymhleth yn y dirwedd y mae ei phresenoldeb parhaus yncysylltu gymaint gyda gwerthoedd cyfoes a gweithgareddaueconomaidd â chyda phrosesau hanesyddol y gorffennol.Introduction6.1 The long term conservation of Offa’s Dyke is not just asimple matter of identifying threats to the monument andremoving them and/or repairing their effects. It is aboutengaging with a complex landscape feature whose ongoingexistence is linked as much to contemporary values andeconomic activities as past historic processes.Diffinio amcanion cadwraeth6.2 Mae deall Clawdd Offa fel strwythur o arwyddocâd eango reidrwydd yn golygu delio â phenderfyniadau rheoli anodd.Er enghraifft, mae coed a all fod yn gysylltiedig â difrodgwreiddiau i ffabrig yr henebyn hefyd efallai yn goed parcdirag arwyddocâd hanesyddol ynddynt eu hunain. Mae’n bosibleu bod yn werthfawr i’r ffermwr fel cysgod i anifeiliaid. Efallaieu bod o bwysigrwydd biolegol neu ecolegol ehangach, ac yngwneud cyfraniad esthetig pwysig i’r dirwedd. Beth yw’rflaenoriaeth o safbwynt cadwraeth? Caiff y sefyllfa eiphwysleisio yn ffurfiol pan fo dynodiadau amddiffyniadstatudol yn gwrthdaro, megis darnau o’r clawdd yn SwyddGaerloyw lle mae’r gwrthglawdd yn rhedeg trwy Safle oDdiddordeb Gwyddonol Arbennig, ac yn ffurfio cynefin mochcoed sy’n cael eu gwarchod dan y gyfraith.6.3 Efallai nad yw adnabyddiaeth craidd y problemau erydiadffisegol y mae’r clawdd yn eu hwynebu mor syml ag y mae’nymddangos. Mae arolygon a baratowyd o bersbectifauarchaeolegol (Hoyle a Vallender 1997) a phersbectif rheolillwybrau (Cutts 1998) wedi cyflwyno barn wahanol iawn osafbwynt faint o niwed llwybr a wnaed i’r gwrthglawdd, a’rmewnbwn rheoli sydd ei angen o ganlyniad. Yn yr un modd,mae problem honedig niwed gan foch coed i’r clawdd yndestun anghytundeb amlwg o ran difrifoldeb ymddangosiadolgyda grwpiau diddordeb penodol.6.4 Mae angen cytundeb ar ran pawb ar ddulliau o drincadwraeth (megis, er enghraifft, adlinellu Llwybr Clawdd Offaoddi ar y gwrthglawdd) a’r paramedrau — o fewn cyfyngiadaunewid derbyniol — lle bernir bod ymyrraeth o’r fath yn briodolyn y lle cyntaf.Defining the conservation aims6.2 Understanding Offa’s Dyke as a structure of widesignificance necessarily involves grappling with difficultmanagement decisions. For example, trees which might beassociated with root damage to the fabric of the monument,are perhaps also 19th-century parkland plantings of historicalmerit in themselves, have value to the farmer as shelter forstock, may be of botanical or wider ecological importance, andmake a notable aesthetic contribution to the landscape. Whatis the conservation priority? This situation is formallyemphasised where conflicting designations of statutoryprotection apply such as sections of the dyke inGloucestershire where the earthwork runs through a Site ofSpecial Scientific Interest, is a Scheduled Ancient Monument,and forms a habitat for badgers which are legally protected.6.3 Even the core identification of the physical erosionproblems the dyke faces may not be so straightforward as itappears. Surveys prepared from contrasting archaeological(Hoyle and Vallender 1997) and path management perspectives(Cutts 1998) have come up with very different views of theextent of path damage to the earthwork and the suggestedmanagement input that is accordingly required. Similarly, thesupposed problem of badger damage to the dyke is subject toevident disparities of perceived seriousness by particularinterest groups.6.4 There is a need to agree collectively both conservationapproaches (such as, for example, the realignment of the Offa’sDyke Path off the earthwork) and the parameters — withinstated limits of acceptable change — where such interventionis judged to be appropriate in the first place.Lleoliad y clawdd6.5 Mae Clawdd Offa yn nodwedd unionlin gyda’r bwriadgwreiddiol o berthyn i’r dirwedd o amgylch, a chael ei gweld o’rdirwedd yma, mewn ffordd strwythuredig fwriadol. Mae’rcysylltiad ehangach hwnnw â chyd-destun gweledol eang acamgylcheddol y mae’r clawdd yn mynd trwyddo yn rhangreiddiol o’i hunaniaeth. Felly, os ydym am warchod cymeriad yThe setting of the dyke6.5 Offa’s Dyke is a linear feature originally designed torelate to and be seen from the landscape around it in adeliberately structured way. That wider association with thebroad visual and environmental context through which thedyke passes is very much a core part of its identity.Accordingly, if the character of the dyke is to be preserved,
