Rhywogaethau anfrodorol ymledol (rhywogaethau ymledol) yw planhigion neu anifeiliaid sydd wedi cael eu cyflwyno gan fodau dynol i gorneli o’r byd lle na fyddent i’w gweld yn naturiol. Gallant effeithio ar yr amgylchedd, yr economi, ein hiechyd a’r ffordd rydym yn byw.

Gall rhywogaethau ymledol reoli ecosystemau cyfan, gan drechu a bygwth bioamrywiaeth Cymru. Maent yn un o’r ‘pum prif’ sbardun i ddirywiad ym myd natur ochr yn ochr â llygredd, newidiadau mewn defnydd o’r tir a’r môr, ecsbloetio rhywogaethau a newid hinsawdd.

Mae’r timau Ceidwaid ledled Tirwedd Genedlaethol Bryniau Clwyd a Dyffryn Dyfrdwy yn gweithio ochr yn ochr â thimau o Ymddiriedolaeth Natur Gogledd Cymru a Chyfoeth Naturiol Cymru i helpu i fynd i’r afael â lledaeniad rhywogaethau estron goresgynnol.

Mae’r prif rywogaethau y mae’r Ceidwaid yn mynd i’r afael â hwy ar hyn o bryd yn cynnwys:

Clymog Japan a Jac y Neidiwr – yn bennaf ar hyd y dyfrffyrdd
Creigafal (cotoneaster) – sy’n bygwth ein glaswelltir calchfaen

Gellwch chi helpu a chymryd rhan hefyd wrth wirfoddoli gyda thimau’r Ceidwaid – canfod mwy.
