Gweledigaeth o Dirwedd Mynydd Waun Fawr

Views across upland area in Montgomeryshire

Byddai'r datblygiad arfaethedig yn effeithio ar yr ucheldir hwn yn ardal Mynydd Waun Fawr yn Sir Drefaldwyn Llun: © Lottie Glover

Mae YNM wedi derbyn arian er mwyn cynhyrchu gweledigaeth dirwedd ar gyfer ardal Mynydd Waun Fawr, a ddangosir ar y map isod. Mae'n ymddangos bod yr ardal hon yn fan sy'n gyfoethog o ran bioamrywiaeth, ond mae hefyd yn ganolbwynt i gasgliad o brosiectau cynhyrchu egni arfaethedig, felly mae angen gweledigaeth strategol, gan gynnwys cynllun cyflawni ymarferol yn seiliedig ar y safle, a hynny ar fyrder. Er mwyn creu'r weledigaeth dirwedd hon, byddwn yn ymgymryd ag arolygon ac yn gweithio gyda pherchnogion tir, rheolwyr tir a phartïon eraill allai fod â diddordeb, er mwyn ceisio adnabod opsiynau a chyfleoedd priodol ar gyfer gwaith adfer ecolegol a gwella cysylltedd.

Yr hyn rydym eisoes yn ei wybod

Mae'r rhan anghysbell hon o sir Drefaldwyn yn parhau i fod ag ardaloedd helaeth o gynefinoedd sy'n cynnal ystod amrywiol o fywyd gwyllt. Ystyrir bod nifer o'r cynefinoedd sy'n hysbys o ardal y prosiect dan ddigon o fygythiad i warantu iddynt gael eu hamddiffyn gan y gyfraith. Mae Adran 7 o Ddeddf yr Amgylchedd (Cymru) 2016 yn adnabod y canlynol fel cynefinoedd ucheldir a rhostir yng Nghymru y dylid eu blaenoriaethu er mwyn cynnal ac ehangu bioamrywiaeth:

Rhostir yr Ucheldir
Gorgors
Sgydau dŵr ucheldirol, ffeniau a chorsydd
Cynefinoedd creigiau mewndirol a mariandiroedd

Nid yn unig yw'r cynefinoedd hyn yn werthfawr oherwydd y bywyd gwyllt maent yn eu cynnal, ond maent hefyd yn cyflawni myrdd o wasanaethau ecosystem, yn fwyaf nodedig storio carbon yn yr eangderau o fawndir. Mae'r ardal hon hefyd yn ddalgylch lle ceir nifer o afonydd oddi mewn iddi, sy'n golygu bod gweithgaredd yr ymgymerir â hi o fewn yr ardal yn cael effaith lawer ehangach.

Yr hyn y byddwn yn ei wneud

Mae'r prosiect yn rhedeg hyd at fis Mawrth 2025. Byddwn yn:

Cynnal arolwg o ardal y prosiect er mwyn adnabod mannau allweddol o ran bioamrywiaeth (cynefinoedd a rhywogaethau).
Bydd yr arolygon hyn hefyd yn cael eu defnyddio i adnabod ardaloedd sy'n addas ar gyfer adferiad ecolegol, ac ardaloedd lle gall yr adferiad hwn sicrhau cysylltedd ecolegol unwaith eto.
Byddwn yn gweithio gyda pherchnogion tir a rheolwyr tir i adnabod opsiynau a chyfleoedd y gellid eu cefnogi.
Byddwn yn defnyddio'r cyfan o'r uchod er mwyn adnabod gweledigaeth dirwedd, gan roi cynllun cyflawni ymarferol yn seiliedig ar safle ar gyfer yr ardal brosiect gyfan.

A landscape view showing a blue lake with irregular banks and another in the distance behind. Around the lakes is green-yellow-orange vegetation (grassland, scrub and bog). There is a blue sky with some white clouds.

A wide landscape view. There is green grassland in foreground with yellow flowers. In the middle distance is a wetland with a few small scattered willow trees. Beyond the view stretches towards a long level hill. The sky is grey clouds.

A small area of blanket bog (wetland), which is largely green vegetation, dotted with white cottongrass and hummocks of heathers. In the distance are a couple of small hills and some trees. The sky is grey clouds.

Looking over an area of blanket bog with dense patches of white cottongrass. The bottom two thirds of the image shows this largely green wetland, then there is a band of trees and a few wind turbines. The sky is scattered clouds with patches of blue sky.

A largely green view with light grey clouds. There are patches of brown and green gorse, long green rushes and short green grass, in the foreground. In the background is a mixture of wetland, trees and grassland. There is a small hill on the right which is a mixture of bracken and trees.

A wetland (bog) dominates this image. Areas of light green Sphagnum are interspersed by grasses, heathers and white cottongrass. In the distance on the right hand side is a bracken covered slope, and there are some distant hills and mountains beyond.

A wide landscape view. In the foreground, taking up two thirds of the image, is a tussocky wetland of green and brown grasses, with a few scattered small trees. In the distance is a green grassed hill with some trees and in the far distance is a long mountain range.

Three people in waterproofs carrying rucksacks looking out at a wide landscape view of fields and hedges and a mountain beyond.

An upland lake reflecting a sky of scattered clouds. The lake is surrounded by grassland and wetland habitats in hues of green and yellow-brown. In the foreground, is an area of gorse scrub covered in yellow flowers.

A wide landscape view of an expansive upland area of grassland, blanket bog, lakes and small patches of scrub. There are a couple of sheep in the mid foreground. The sky is largely blue with some white clouds.

Ariennir y prosiect yma gan y Rhaglen Rhwydweithiau Natur. Mae'n cael ei ddarparu gan y Gronfa Treftadaeth, ar ran Llywodraeth Cymru.

Sut allwch chi helpu?

Mae ymgysylltu gyda'r gymuned leol yn allweddol i lwyddiant y prosiect hwn.
