English: I too welcome this debate today and the 'State of Nature 2016 Wales' report, in which I think many organisations have played a very valuable part in helping to produce and highlight. Of course, there are causes for concern, which Members have already mentioned, and a need for the Welsh Government and other public bodies to act to address those concerns. As with other Members here, I am a champion, through the Wildlife Trust, for a particular species - in my case, the water vole. The decline in the water vole population in Britain is quite dramatic. In fact, it's the most serious decline of any wild mammal in Britain in the last century. Between 1960 and 2004, it's estimated that that fall was around 95 per cent. So, obviously, there are very serious concerns in terms of the water vole population in Wales, and beyond Wales in terms of Britain as a whole. So, the organisations concerned with biodiversity and the water vole population highlight habitat loss, as you would expect, and fragmentation of habitats as factors involved in that decline; predation by mink, of course, which has been a big factor; water abstraction and pollution of the waterways; and management of reens and ditches, and the role of intensive agriculture in that. So, there's probably a reasonable degree of consensus in terms of the prime causes of that fall in water vole population and also, I think, quite a degree of agreement in terms of what needs to be done - some of the things that most need to be done to address that decline - so, reintroduction programmes for water voles, control of the mink population, restoration of habitat and reversal, and certainly a halting of the decline in the habitat that supports them; that's waterways and riverbanks and more extended areas of natural habitat not fragmented by development. So, when we look at all of those issues, Llywydd, I think it's clear that the environment Act and the well-being of future generations Act, as mentioned by others, are absolutely vital to the general picture and to water voles as well. We need to make sure that they are implemented as effectively as possible. For me, I guess, locally, my experience of the water vole population is mainly around the Gwent levels. We have got an amazing network of reens and waterways there. They have been carefully managed over the centuries. Nonetheless, they are under threat, of course. One of the main threats is the proposed M4 relief road across the Gwent levels. So, I think it will be a major test of the legislation that I have referred to as to whether the biodiversity issues, including the water vole population, are adequately and sufficiently factored into decision making on that particular proposal. Certainly, I am working very closely with the wildlife trusts and a range of other organisations to try and get the key message across - that it's no good to anyone in terms of ensuring good biodiversity in Wales if we are talking the talk, as it were. When it comes to key decisions, we have to walk the walk.
Welsh: Rwyf fi hefyd yn croesawu'r ddadl hon heddiw ac adroddiad 'Sefyllfa Byd Natur Cymru 2016', ac rwy'n meddwl bod llawer o sefydliadau wedi chwarae rhan werthfawr iawn yn helpu i'w gynhyrchu a thynnu sylw ato. Wrth gwrs, mae yna bethau sy'n peri pryder wedi cael sylw eisoes gan yr Aelodau, ac mae angen i Lywodraeth Cymru a chyrff cyhoeddus eraill weithredu i fynd i'r afael â'r pryderon hynny. Fel Aelodau eraill yma, rwy'n hyrwyddwr rhywogaeth benodol, drwy'r Ymddiriedolaeth Bywyd Gwyllt - llygoden y dŵr yn fy achos i. Mae'r dirywiad ym mhoblogaeth llygod y dŵr ym Mhrydain yn eithaf dramatig. Yn wir, dyna'r dirywiad mwyaf difrifol o holl famaliaid gwyllt Prydain yn ystod y ganrif ddiwethaf. Rhwng 1960 a 2004, amcangyfrifir bod y gostyngiad oddeutu 95 y cant. Felly, yn amlwg, mae yna bryderon difrifol iawn ynglŷn â phoblogaeth llygod y dŵr yng Nghymru, a thu hwnt i Gymru ym Mhrydain yn gyffredinol. Felly, mae'r sefydliadau sy'n ymwneud â bioamrywiaeth a phoblogaeth llygod y dŵr yn tynnu sylw at y cynefin a gollwyd, fel y byddech yn ei ddisgwyl, a darnio cynefinoedd fel ffactorau sy'n cyfrannu at y dirywiad hwnnw; eu hysglyfaethu gan y minc, wrth gwrs, sydd wedi bod yn ffactor mawr; tynnu dŵr a llygru'r dyfrffyrdd; a rheoli ffosydd draenio a ffosydd, a rôl amaethyddiaeth ddwys yn hynny. Felly, mae'n fwy na thebyg fod cryn dipyn o gonsensws ynglŷn â phrif achosion y gostyngiad hwnnw ym mhoblogaeth llygod y dŵr a hefyd, rwy'n credu, cryn dipyn o gytundeb o ran yr hyn sydd angen ei wneud - rhai o'r pethau sydd fwyaf o angen eu gwneud i fynd i'r afael â'r gostyngiad - felly, rhaglenni ailgyflwyno llygod y dŵr, rheoli poblogaeth minc, adfer cynefin a'i newid yn ôl, ac yn sicr, atal y dirywiad yn y cynefin sy'n eu cynnal, sef dyfrffyrdd a glannau afonydd ac ardaloedd mwy estynedig o gynefin naturiol nad yw wedi'i ddarnio gan ddatblygiad. Felly, pan edrychwn ar bob un o'r materion hynny, Lywydd, rwy'n credu ei bod yn amlwg fod Deddf yr amgylchedd a Deddf llesiant cenedlaethau'r dyfodol, fel y crybwyllwyd gan eraill, yn gwbl hanfodol i'r darlun cyffredinol ac i lygod y dŵr yn ogystal. Mae angen i ni wneud yn siwr eu bod yn cael eu gweithredu mor effeithiol â phosibl. I mi, rwy'n dyfalu, yn lleol, mae fy mhrofiad o boblogaeth llygod y dŵr yn bennaf o amgylch gwastadeddau Gwent. Mae gennym rwydwaith anhygoel o ffosydd a dyfrffyrdd yno. Maent wedi cael eu rheoli'n ofalus dros y canrifoedd. Serch hynny, maent dan fygythiad, wrth gwrs. Un o'r prif fygythiadau yw ffordd liniaru arfaethedig yr M4 ar draws gwastadeddau Gwent. Felly, rwy'n meddwl y bydd yn brawf mawr i'r ddeddfwriaeth y cyfeiriais ati o ran a yw materion bioamrywiaeth, gan gynnwys poblogaeth llygod y dŵr, yn cael eu hystyried yn ddigonol wrth benderfynu ar y cynnig hwnnw. Yn sicr, rwy'n gweithio'n agos iawn gyda'r ymddiriedolaethau bywyd gwyllt ac amrywiaeth o sefydliadau eraill i geisio cyfleu'r neges allweddol - nad yw sicrhau bioamrywiaeth dda yng Nghymru yn gwneud unrhyw les i neb os mai siarad gwag a wnawn. Gyda phenderfyniadau allweddol, mae'n rhaid i ni fod cystal â'n gair.
