About the event

Clirio Jac-y-Neidiwr yn Clwt-y-Bont / Clearing Himalayan Balsam
Beth ydi Jac-y-Neidiwr (Himalayan Balsam)? Fe’i cyflwynwyd i’r DU ac Ewrop yn y 19eg ganrif fel planhigyn gardd addurnol. Ers hynny mae wedi dianc rhag cael ei drin ac wedi lledaenu’n ymosodol yn y gwyllt.

Rhai o’r problemau (er ei fod yn edrych mor ddel!)
-Mae’n cystadlu gyda a threchu planhigion brodorol, yn enwedig ar hyd glannau afonydd a choetiroedd llaith, trwy dyfu’n drwchus iawn a’u cysgodi allan.
-Mae’n marw’n ôl yn llwyr yn y gaeaf, gan adael pridd noeth, erydadwy – gan gyfrannu at erydiad glannau afonydd a cholli cynefinoedd.
-Mae gwenyn wrth eu bodd ag o (oherwydd bod cymaint o neithdar), ond gall hyn leihau peillio planhigion brodorol, gan dynnu peillwyr i ffwrdd o rywogaethau mwy pwysig yn ecolegol.
-Mae’r rhywogaeth ymledol yma yn bryder mawr ac yn cymeryd drosodd ardaleodd helaeth o’n tiroedd.

Dewch draw i glirio gyda gwirfoddolwyr cymunedol!

Byddan yn cyfarfod ger Afon Caledffrwd, Clwt-y-Bont am 10yb.

What is Himalayan Balsam? It was introduced to the UK and Europe in the 19th century as an ornamental garden plant. It has since escaped cultivation and spread aggressively in the wild.

Some of the problems (even though it looks so pretty!):
-It outcompetes native plants, especially along riverbanks and damp woodlands, by growing very densely and shading them out.
-It dies back completely in winter, leaving bare, erodible soil — contributing to riverbank erosion and habitat loss
-Bees love it (because it’s so nectar-rich), but this can reduce pollination of native plants, drawing pollinators away from more ecologically important species.
-This invasive species is a major concern and is taking over large areas of our lands.

Come and clear it with community volunteers!

We will meet near Afon Caledffrwd, Clwt-y-Bont at 10am.
