Eisteddai Loggerheads islaw clogwyni calch trawiadol Dyffryn Alun, lle mae\u2019r afon yn mynd drwy geunentydd coediog serth a glaswelltir agored a diarffordd. Mae dylanwad calchfaen i\u2019w weld ymhob rhan o\u2019r parc yn ogystal ag ym mhentrefan Cadole gerllaw. Mae\u2019r calchfeini wedi siapio edrychiad y tirlun yn ogystal \u00e2\u2019r planhigion sy\u2019n tyfu yma \u2013 ar y glaswelltir llawn blodau ar ben y bryn ac yn y coetiroedd gwlyb ger yr afon.<\/p>\n

\"Loggerheads<\/p>\n

Mae Parc Gwledig Loggerheads yn safle rhyngwladol bwysig ar gyfer cadwraeth, wedii ddynodin Ardal Cadwraeth Arbennig (ACA) ac yn Safle o Ddiddordeb Gwyddonol Arbennig (SoDdGA).<\/p>\n

Y coetir ynn cymysg, y coetir gwlyb a\u2019r glaswelltir carreg galch sy\u2019n ei wneud mor arbennig. Ond mae llawer o blanhigion ac anifeiliaid anghyffredin hefyd ac mae\u2019r afon ei hun yn gynefin pwysig.<\/p>\n

Mae\u2019r priddoedd ar y clogwyni yn denau, yn brin eu maethynnau ac yn alcal\u00efaidd oherwydd y garreg galch waelodol. Mae planhigion brau sy\u2019n arbenigol i\u2019r amodau hyn yn ffynnu, yn cynnwys rhosyn y graig, pig-yr-aran ruddgoch, bwrned, teim gwyllt, mefus gwyllt ac eurinllys, sy\u2019n creu toreth o liwiau ar ddechrau\u2019r haf.<\/p>\n

\"Bloody
Bloody Cranesbill<\/figcaption><\/figure>\n

Mae\u2019r planhigion hyn yn anhepgor i lawer o l\u00f6ynnod byw a gwyfynod. Mae\u2019r glaswelltiroedd yn cynnig cartref i lawer o l\u00f6ynnod byw cyffredin megis y gwyn blaen oren a\u2019r fantell dramor ond o bwys arbennig mae\u2019r gwibiwr brith \u2013 gl\u00f6yn byw prin y mae\u2019i lindys ond yn bwydo ar ddyrnaid o blanhigion o deulu\u2019r mefus.<\/p>\n

Cadwch lygad am y ddiadell o ddefaid Hebrid\u00ebaidd yn pori yn y llannerch goedwigol y tu \u00f4l i\u2019r clogwyni. Mae\u2019r br\u00eed caled hwn yn bwyta\u2019r prysgwydd gwydn, pigog ac yn ei atal rhag tresmasu ar y glaswelltir.<\/p>\n

Mae\u2019r coetiroedd ynn, sy\u2019n cael eu hadnabod fel Coedydd Dyffryn Alun, yn ymestyn ar hyd y dyffryn o Loggerheads i Rydymwyn dair milltir i\u2019r gogledd. Onnen ydy\u2019r goeden drech ond mae llawer o rai eraill yn cynnwys llwyfen lydanddail, collen a derwen. Yn y gwanwyn mae\u2019r coetir wedi\u2019i garpedu gan graf gwyllt egr, clychau\u2019r gog, blodau\u2019r gwynt gwyn a llygad Ebrill melyn.<\/p>\n

Y gwanwyn ydy\u2019r amser gorau hefyd i ddod i wylio adar ac fe all y rheini gyda chlust fain glywed y tingoch, y gwybedog mannog a\u2019r gwybedog brith. Mae telor y coed i\u2019w gael weithiau ond mae telor yr helyg, y siff-siaff a\u2019r telor penddu yn fwy cyffredin.<\/p>\n

Mae Afon Alun yn darparu cartref i lawer o rywogaethau diddorol megis pysgod penlletwad a dyfrgwn, sydd wedi dychwelyd i\u2019r afon yn y blynyddoedd diwethaf. Mae\u2019r pryfetach toreithiog yn denu llawer o adar hefyd.<\/p>\n

Bydd mynd am dro ar hyd yr afon yn llawn llif yn cael ei wobrwyo\u2019n aml gan gip ar fronwen y d\u0175r, aderyn brown bychan gyda bron wen sy\u2019n siglo i fyny ac i lawr ar graig neu\u2019n hedfan yn gyflym ar hyd yr afon. Mae\u2019r siglen lwyd, aderyn eiddil gyda bol melyn a chynffon hir sy\u2019n siglo\u2019n ddi-baid, yn gyffredin hefyd. Pan fo\u2019r afon yn diflannu, gellwch gael cipolwg weithiau ar las y dorlan yn hela am y pysgod sydd yn y golwg.<\/p>\n

Mae ymlusgiaid yn cynnwys y wiber, y neidr ddafad a\u2019r fadfall yn ffafrio\u2019r calchbalmentydd diarffordd a glaswelltiroedd tawelach, oddi wrth yr ardaloedd ymwelwyr prysurach.<\/p>\n

Denodd y calchfaen ddiwydiant i\u2019r ardal. Cafodd y gwythiennau mwynol bras yn y graig eu mwyngloddio\u2019n eang am blwm yn ystod y ddeunawfed a\u2019r bedwaredd ganrif ar bymtheg, a chodwyd pentref Cadole ar gyfer y mwynwyr.<\/p>\n

Gallwch ddysgu mwy am yr hanes ar dudalen treftadaeth ddiwydiannol Loggerheads<\/a>.<\/p>\n

Ers blynyddoedd lawer mae\u2019r calchfeini hardd wedi ysbrydoli artistiaid, fel yr artist tirwedd Prydeinig Richard Wilson, yn ogystal \u00e2 denu nifer fawr o ymwelwyr.<\/p>\n

Cynlluniwch ymweliad.<\/a><\/p>\n
