English: To answer the question directly, I think first of all, if we're going to take any steps towards declaring that there is a biodiversity or nature emergency, we have to understand where we are at the moment. We have to realise that a lot of the data that we are using to create that statement is based on studies that are, by now, 20 or 30 years old. If you look at the 'State of Nature' report, one of the statements in that report is that, 'one of the habitats we know least about is the uplands,' because there's not enough core data to show the true state of the habitats that we have today. As Councillor Vaughan said, we've seen revolutionary change in the stocking of the uplands over a period of 30 years, since we decoupled productivity and farm payments, with the change to area payments. Particularly for upland farmers - and this is something that's been missed completely in the report by Chris Clark, 'Less is more', which Arfon Williams referred to - if you look at the genuinely upland areas of our farms, they have almost no stock, and there are very large areas like that for a significant portion of the year. That has created additional density in some of the fields and some of the lowland areas, but we have to properly tackle data at a farm level, and at a local level, in order to understand where we are now. I don't think that we're anywhere close to that, and I think that that's at the heart of some of the problems with Rewilding Britain and Summit to Sea's perceptions: the level of understanding of the data doesn't exist at present, and we have to be much more careful in the way that we gather data, and how we then use it.
Welsh: I ateb y cwestiwn yn uniongyrchol, dwi'n credu yn gyntaf oll, os ŷn ni'n mynd i gymryd unrhyw gam tuag at ddatgan bod yna argyfwng bioamrywiaeth neu natur, mae'n rhaid i ni ddeall lle ŷn ni ar hyn o bryd. Mae'n rhaid i ni sylweddoli bod lot o'r data rŷn ni'n defnyddio ar gyfer creu'r datganiad yna yn seiliedig ar astudiaethau sydd, erbyn hyn, yn rhyw 20 i 30 mlwydd oed. Os ŷch chi'n edrych ar yr adroddiad 'Cyflwr Natur', un o'r datganiadau yn yr adroddiad yna yw ' one of the habitats we know least about is the uplands,' oherwydd does yna ddim digon o ddata craidd yn dangos gwir gyflwr y cynefinoedd sydd gennym ni heddiw. Ac fel dywedodd y Cynghorydd Vaughan, rŷn ni wedi gweld newid chwyldroadol yn stocio'r ucheldir dros 30 mlynedd, mewn gwirionedd, ers i ni ddatgyplysu cynhyrchiant a thaliadau ffermydd, ac iddyn nhw newid i daliadau sy'n seiliedig ar ardal. Yn enwedig i ffermwyr yr ucheldir - ac mae hyn yn rhywbeth sy'n cael ei golli yn gyfan gwbl yn adroddiad Chris Clark, 'Less is more', y gwnaeth Arfon Williams gyfeirio ato - os ŷch chi'n edrych ar diroedd wir ucheldirol ein ffermydd ni, maen nhw bron a bod yn gwbl ddi-stoc, ac mae ardaloedd mawr iawn felly am gyfnod hir iawn o'r flwyddyn. Mae hynny wedi creu dwysedd ychwanegol yn rhai o'r caeau ac ar beth o'r tir lawr, ond mae'n rhaid i chi'n wirioneddol fynd i'r afael â'r data ar lefel fferm, ac ar lefel leol, er mwyn deall lle ŷn ni nawr. Dwi ddim yn credu ein bod ni'n unman yn agos at hynny, a dwi'n credu bod hynny wrth wraidd rhai o'r problemau efo canfyddiadau Rewilding Britain a Summit to Sea: dyw'r lefel o ddeallusrwydd yna yn y data ddim yn bodoli ar hyn o bryd, ac mae angen i ni fod yn llawer mwy craff yn y modd rŷn ni'n casglu data, a sut rŷn ni wedyn yn ei ddefnyddio fe.
