Yn ôl arweinydd y prosiect, Ruth Stronge, mae hynny wedi creu lle ar gyfer tegeirianau prin a phlanhigion eraill, ac mae hynny, yn ei dro, wedi rhoi hwb i bryfed ac wedi denu adar i'r ardal.
Project leader Ruth Stronge says that this has made space for rare orchids and other plantlife, which in turn has boosted insect life and encouraged birds to the area.
