Head For Change

What a transformation!

A huge thank you to our fantastic volunteers from the Friends of Cardiff Reservoirs, who have been hard at work clearing back brambles that had taken hold along the boundary fence. 🪾🌿

Their efforts have helped free the young whips planted there, giving them the space and light they need to flourish. 🌱

Great work from everyone involved! 👏

Am drawsnewidiad!

Diolch o galon i’n gwirfoddolwyr gwych o Gyfeillion Cronfeydd Dŵr Caerdydd, sydd wedi bod yn gweithio’n galed yn clirio’r mieri a oedd wedi cydio ar hyd ffens y ffin. 🪾🌿

Mae eu hymdrechion wedi helpu i ryddhau’r coed ifanc sydd wedi eu plannu yno, gan roi’r lle a’r golau y maen nhw eu hangen i dyfu’n gryf. 🌱

Gwaith gwych gan bawb fu’n cymryd rhan! 👏

Mae'r artist lleol ac Ymarferydd Celfyddydau ac Iechyd, Grace Jandrell, yn gwahodd pobl i gymryd rhan mewn prosiect Celfyddydau ac Iechyd unigryw ac AM DDIM sy'n archwilio sut y gall natur, creadigrwydd a chymuned gefnogi llesiant. Bydd y prosiect yn ffurfio rhan o'i hastudiaethau MA.

Drwy deithiau cerdded tywysedig o amgylch y gronfa ddŵr a gweithgareddau creadigol gan gynnwys lluniadu, collage, plygu papur a phaentio, byddwch yn creu eich map personol eich hun o'r safle ac yn archwilio beth mae'r gronfa ddŵr yn ei olygu i chi. Nid oes angen unrhyw brofiad artistig, dim ond parodrwydd i gymryd rhan a rhoi cynnig arni!

📅 Dydd Mawrth 25 Awst
🕙 10yb-12yp

🦋 This stunning Painted Lady butterfly enjoying nectar from lesser knapweed is more than just a beautiful sight. It’s a reminder of how important our wildflowers are.

For butterflies, bees and other pollinators, every flower can provide much-needed nectar and pollen. By protecting and restoring native wildflower habitats around our reservoirs, we’re helping pollinators feed, shelter and thrive.

🦋 Mae’r llun prydferth yma o Löyn yr Ysgall yma’n mwynhau’r neithdar o bengaled Ffrainc yn fwy na dim ond gwledd i’r llygaid. Mae’n ein hatgoffa pa mor bwysig yw ein blodau gwyllt.

I bili palas, gwenyn a pheillwyr eraill, mae pob blodyn yn darparu neithdar a phaill y mae mawr angen amdano. Trwy ddiogelu ac adfer cynefinoedd blodau gwyllt brodorol o amgylch ein cronfeydd natur, rydym yn helpu peillwyr i fwydo, cysgodi a ffynnu.

📸 Ydych chi wedi gweld unrhyw loÿnnod byw wrth fynd am dro yn ddiweddar? Rhannwch eich lluniau yn y sylwadau!
