Ash dieback has spread rapidly through the Welsh countryside and has now affected all of North Wales Wildlife Trust's nature reserves with ash trees present.

Invasive non-native species – also known simply as invasive species or INNS - have been introduced by humans, intentionally or unintentionally, beyond their natural range. Acknowledged as one of the top five drivers of biodiversity loss globally, their spread threatens the survival of our native species, and can cause damage to our environment, economy, our health and the way we live.

Mae’r DU wedi colli hyd at 90% o’i dolydd morwellt yn y ganrif ddiwethaf, sydd wedi cael canlyniadau negyddol i iechyd a gwydnwch ein systemau arfordirol. Yn 2019, ffurfiodd Prifysgol Abertawe, yr elusen Project Seagrass a WWF-UK gydweithrediad i ddechrau adfer rhywfaint o'r hyn yr ydym wedi'i golli. Ar yr un pryd, dros y chwe blynedd diwethaf mae Prifysgol Abertawe wedi bod yn arwain treialon ledled Cymru i ddatblygu dulliau priodol ar gyfer adfer morwellt. Yma yn Ngogledd Cymru, rydym wedi ymuno gyda’r partneriaid i gychwyn archwilio sut allwn ddod a’r prosiect cyffrous yma i Ogledd Cymru. Rydym wedi sicrhau cyllid gan Gronfa Dreftadaeth y Loteri Genedlaethol i gyflawni rhaglen waith adfer arfaethedig sy’n dderbyniol yn gymdeithasol ac yn ecolegol gadarn ac rydym ni eisiau i chi gymryd rhan. Wrth gymryd rhan fyddwch chi yn helpu ni i adfer morwellt yng Ngogledd Cymru.
