Fel y nodwyd ar Medi 14eg, roedd yn destun syndod a llawenydd i Lywodraeth Cymru glywed fis Awst diwethaf fod pâr o weilch y pysgod wedi penderfynu nythu ar safle Fferm Gilestone.  Mae gweilch y pysgod, ynrhywogaeth Atodlen 1sy'n cael ei gwarchod o danDdeddf Bywyd Gwyllt a Chefn Gwlad 1981, a dyma’r tro cyntaf iddynt gael eu gweld mor bell i'r de yng Nghymru ers tua 200 mlynedd.
As stated on September 14th, the Welsh Government was surprised and delighted to learn in August last year that a pair of ospreys had decided to nest on the Gilestone Farm site. Ospreys are aSchedule 1 speciesprotected under theWildlife and Countryside Act 1981and it is first time they have observed this far south in Wales in around 200 years.
