14.14 Bydd angen datblygu rhagor o fanylion ar y prosiect hwn a'u trafod yn fanwl gyda Cadw, Cyngor Sir Ceredigion a CNT er mwyn cadarnhau hyd a lled unrhyw archwiliadau cychwynnol a fydd yn angenrheidiol cyn ffurfio ceisiadau am ganiatadau/cynllunio. Gellid wedyn ffurfio tasg gyfunol o gynnal archwiliadau cychwynnol ar gyfer cennau, ystlumod ac archaeoleg, gan ganolbwyntio ar yr effeithiau penodol. Gellid gyrchu arian ar gyfer gwaith o'r fath drwy cam datblygu Grant Treftadaeth CTL (os ystyrir bod y ffynhonnell hyn yn addas ac os bydd y cais yn llwyddiannus).
14.15 Mae safle Gwaith Mwyn Cwmystwyth yn darparu nifer o gyfleoedd ar gyfer gweithio ar y cyd gydag arbenigwyr ar fwyngloddiau, anturwyr mwyngloddiau/ogofwyr, arbenigwyr archeolegol, ecolegol a daearegol ynghyd â gweithio gyda'r gymuned leol i hyrwyddo'r darn pwysig hwn o dreftadaeth
ddiwylliannol a naturiol y rhanbarth. Rhaid hysbysu'r cenedlaethau a ddaw o bwysigrwydd y safle hwn, a chynnal diddordeb ynddo.
14.16 Rhaid hefyd ystyried cynaladwyedd hirdymor y safle o safbwynt creu rhyw fath o incwm i'w ddefnyddio ar gyfer cynnal a chadw, atgyweiriadau a chofnodi.
Ynghyd â'r posibiliadau a drafodir uchod, mae'r safle yn cynnig cyfleoedd ymchwil ar yr amgylchedd (archaeoleg, ecoleg, daeareg, llygredd) a gallai cynlluniau cofnodi yn y dyfodol ddod o ariannu ymchwil o'r fath.
14.17 Mae hiroes Ymddiriedolaeth Mwyngloddiau Cambria hefyd yn bwysig i ddyfodol hirdymor y safle. Gallai'r Ymddiriedolaeth recriwtio aelodau newydd, yn ddelfrydol gan gynnwys aelodau o'r gymuned leol ac yn arbennig y porwyr sydd â diddordeb materol yn y safle. Gallai'r Ymddiriedolaeth weithio gyda grwpiau a chymdeithasau lleol sydd eisoes yn bodoli er mwyn hyrwyddo'r safle ac hybu cyfranogiad mewn prosiectau ar y safle yn y dyfodol, naill-ai y rhai a amlinellir yn y ddogfen hon, neu astudiaethau a phrosiectau y dyfodol. Dangosodd y maint y gynulleidfa a ddaeth i'r Digwyddiad Cymunedol a drefnwyd yn ystod y prosiect hwn bod yna ddiddordeb lleol sylweddol yn nyfodol y safle. Efallai y dylid ystyried sefydlu grŵp neu gymdeithas leol sydd yn gysylltiedig â, neu yn rhan o Ymddiriedolaeth Mwyngloddiau Cambria.

APPENDIX 1: CAMBRIAN MINES TRUST –THE WAY AHEAD DOCUMENTThe Original Wish List In 2012 Roy Fellows, CMT Director, produced a document entitled ‘Cwmystwyth: A Way Ahead’ which included a wish list of aspirational future works for the site, listed in priority order. The document acknowledged that no works could be undertaken until all relevant permissions and consents regarding all of the various designations of the site were obtained and complied with.
This wish list has been reviewed and a new series of aspirations has been developed, laid out in the main body of the document (Section 9). This original
wish list is reproduced in the following table for reference:

Biological This is one of the most important areas of hill land in Wales for nature conservation. It is of outstanding interest for its range of breeding birds of upland and woodland. Much of the hill vegetation is also of special interest.
The area is built of rocks of Silurian and Ordovician age, and the landform is typical of the ‘slate uplands’ of south-central Wales, with plateau separated by steep-sided valleys. The moorland plateau is largely covered by blanket bog vegetation. Purple moor-grass Molinia caerulea is the dominant plant of these hills, occurring in valley mires, on hill slopes and on the plateau tops.
This dominance is possibly due to management effects of grazing and burning. On the better developed summit blanket bog there is less purple moorgrass and the vegetation may be dominated by hare’s-tail cottongrass Eriophorum vaginatum or deergrass Trichophorum cespitosum, and locally heather Calluna vulgaris can be well represented or dominant. Where the water table is high, as on some watershed mires or in shallow depressions on hill slopes, these communities can be rich in bog-moss species Sphagnum spp., and support a range of higher plants including cranberry Vaccinium oxycoccus, crossleaved heath Erica tetralix, common cottongrass Eriophorum angustifolium and bog asphodel Narthecium ossifragum. Bog-rosemary Andromeda polifolia, here near the southern end of its range, occurs in several locations. Three particularly interesting localities within the site are the watershed mires at the headwaters of the Rivers Elan and Claerwen, the well developed pool and hummock mire at Cors Lwyd and the eroded, but still actively growing, mire complex at Cors Gôch.
These areas support rare plant species.
The acid grasslands on the site tend to have a high representation of purple moor-grass, heath rush Juncus squarrosus or mat-grass Nardus stricta.
Some freely drained areas support bent/fescue Agrostis/Festuca grassland and others have dwarf-shrub heath dominated by heather or bilberry Vaccinium myrtillus. Hillside and streamside flushes are botanically diverse and some support uncommon species, including two localities for bog orchid Hammarbya paludosa.
Crags, scree slopes and stream gorges provide contrasting habitat types that support species that would otherwise be suppressed by grazing, and in areas of high humidity support a spectrum of mosses characteristic of a type confined to the Western Atlantic seaboard. Some of the sessile oak woodlands and mixed woodlands included within the site for ornithological reasons are also of interest for the occurrence of unusual lichens. Mountain lakes within the site support a number of rare species, including water lobelia Lobelia dortmanna, and watercourses, together with their riparian vegetation, are of botanical interest. An
additional feature of scientific interest is the occurrence of plant species tolerant of heavy metals, which grow on old mine workings.
Elenydd is one of the two most important areas in Wales for upland bird species, the other site being Berwyn. It forms the feeding range for a large part of the British population of red kite, which in winter is dependent on the supplies of sheep carrion to be found on the sheepwalks. The availability of carrion also helps support what is probably the greatest density of ravens in Europe, and also large numbers of buzzard. Other raptors feeding or breeding in the upland areas include peregrine, merlin, hen harrier and short-eared owl. Red grouse breed in heather areas, ring ouzel frequent craggy areas, and the hill slopes support populations of wheatear, whinchat and stonechat. Lakes, reservoirs, rivers and streams provide a habitat for goosander, teal, dipper and common sandpiper. The summit plateau mire communities support important wader populations, with possibly the highest Welsh breeding populations of dunlin and golden plover.
Valley mires have good populations of snipe, curlew and lapwing. The woodlands of Elenydd support an outstanding assemblage of breeding bird species. The broadleaved woodland has high populations of breeding summer migrants such as pied flycatcher, redstart and warblers, in addition to the resident species that include woodpeckers, tits, nuthatch and treecreeper. The coniferous woodland contributes additional species, in particular long-eared owl, sparrowhawk, siskin and crossbill. Raptors hunting the open hill breed in both semi-natural and plantation woodland.
Physical Mass Movement (Cwm Ddu): This locality was produced by a very large rotational slump in the Llandovery Series (Silurian). It is remarkable for its size (500 metres wide, 1 km long and 250 metres in vertical range), its spectacularly cliffed backface and a classic debris tongue stretching out from the slump amphitheatre (cwm) across the low-angle footslope and the narrow floodplain of the Ystwyth. This complete set of features is not as well displayed anywhere else in Great Britain.
