Rhywogaethau Anfrodorol Ymledol

Dianc o Erddi!

Cynnwys garddwyr mewn atal 'ymledwyr y dyfodol'

Rydym angen chi! - helpwch ni adnabod ac atal 'ymledwyr y dyfodol'

Rydym yn ymgysylltu gyda garddwyr i adnabod ac atal 'ymledwyr y dyfodol'. Mi fyddwn yn rhoi ffocws mewn chwe lleoliad (gweler map). Byddwn yn edrych ar blanhigion addurnol yn eich gardd i weld pa rhai sy'n lledaenu a hefyd i'w gweld oddi allan i erddi, megis ardaloedd gwarchodedig cyfagos.

Beth ydi rhywogaethau ymledol?

Yn fyd-eang ac yma yng Nghymru, mae planhigion addurnol sy’n ymledu o erddi yn un o’r prif ffynonellau o rywogaethau anfrodorol ymledol (h.y. rhywogaethau ymledol). Nid yw'r rhan fwyaf o'r planhigion addurnol rydyn ni’n dod ar eu traws yn ein gerddi yn achosi problemau fel rhywogaethau ymledol; fodd bynnag, mae'n bosibl y bydd gan nifer bach o rywogaethau'r potensial i ddianc o erddi ac ymledu i'n hamgylchedd naturiol ni, ac effeithio ar yr amgylchedd, yr economi, ein hiechyd a’r ffordd rydyn ni’n byw. Mae rhywogaethau ymledol wedi cael eu hadnabod yn fyd-eang fel un o'r prif pum bygythiad i natur, a gallant ddod yn fwy o broblem oherwydd yr argyfwng hinsawdd.

What are invasive species?

Globally and here in Wales, ornamental garden plants spreading from gardens are one of the main sources of invasive species which affect our native wildlife. The majority of ornamental plants we find in in our gardens are non-native but are not causing problems. However, a small number we label as invasive species because they have escaped from gardens can impact the environment, economy, our health and the way we live. Invasive species have been recognised globally as one of the top five threats to nature and could become an increasing problem because of the climate crisis.

Mae enghreifftiau o rywogaethau ymledol yn cynnwys clymog Japan (Reynoutria japonica), cennin trionglog (Allium triquetrum), crib-y-ceiliog (Crocosmia × crocosmiiflora) a clychau'r-gog Sbaenaidd (Hyacinthoides hispanica). Mae rhywogaethau sydd ddim yn ymledol ar hyn o bryd ond gyda photensial i fod yn ymledol yn cynnwys enghreifftiau fel 'chocolate vine' (Akebia quinata), bachgen llwm (Leycesteria formosa) ac blodyn-y-gwynt Japaneaidd (Anemone × hybrida).

Tomos’ particular interest is in identifying ornamental plants that might escape gardens and become invasive in the wild. He is passionate about engaging the public in environmental issues and in science communication. This has included a gold winning educational exhibit in the Discovery Zone at the Royal Horticultural Society's Chelsea Flower Show in 2019 with the University of Reading. A native of Anglesey, Tomos enjoys hunting for orchids in North Wales and beyond and is a keen gardener.
