Since the event KWT have been supporting local residents others to create a Friends of Gellideg community group to continue the work they started last September.
Ers y digwyddiad hwnnw, mae Cadwch Gymru'n Daclus wedi bod yn cefnogi trigolion lleol eraill i greu grŵp cymunedol Cyfeillion Gellideg i barhau â'r gwaith y dechreuon arno nhw fis Medi diwethaf.
