Rwy’n siŵr bod y rhan fwyaf o’r ffermwyr gymerodd ran yn Tir Gofal wedi gweld gwahaniaeth positif yn yr amgylchedd a byd natur ar eu ffermydd, ond o edrych ar effeithiau’r cynllun yn ei gyfanrwydd, gwelir na chafodd fawr o effaith ar gynyddu niferoedd rhywogaethau â blaenoriaeth, sef un o’i brif amcanion o’r cychwyn.  Adlewyrchir y methiant hwnnw gwaetha’r modd yn yr argyfwng cenedlaethol sy’n parhau i wynebu bioamrywiaeth ac a ddarluniwyd mor glir yn yr adroddiad ar Sefyllfa Byd Natur.  Ar nodyn mwy gobeithiol, fe esgorodd y cynlluniau ar rai canlyniadau amgylcheddol ychwanegol mwy buddiol, gan gynnwys lleihau effeithiau’r newid yn yr hinsawdd, er nad oeddynt ymhlith amcanion gwreiddiol.  Bydd y buddiannau hynny’n parhau trwy fesurau tebyg ac ychwanegol yn Glastir ond mae’n bwysig ein bod yn anelu lawer yn uwch os ydym am sicrhau dyfodol mwy cynaliadwy.
While I am sure many farmers who participated in Tir Gofal will have personally recorded a positive difference in the wildlife and environment on their farms, in overall terms the scheme has been shown to have had limited impact at improving the populations of priority species, a key objective at the outset. This failure has been borne out unfortunately in the on-going national crisis facing biodiversity so clearly communicated through the State of Nature report. On a more positive note, the schemes have shown some beneficial additional environmental outcomes including for climate change mitigation, despite not being specifically designed for this purpose. These benefits will be continued through funding of similar and additional measures within Glastir but it is important we raise our ambitions much higher if we are to ensure a more sustainable future.
