From sleepy slow worms and sunbathing adders to an abundance of newts – last week had them all!

**Scroll down for Welsh**  **Rholiwch i lawr i weld y testun Cymraeg**

Wow what a fantastic couple of days we had last week!  The Snowdonia Society teamed up with North Wales Wildlife Trust (NWWT) and the Amphibian and Reptile Conservation Trust (ARC – trust) to put on some training about surveying for amphibian and reptiles. 

Did you know that both amphibians and reptiles are incredibly under recorded groups in the UK?  Did you know you can change that?  If you see a frog, toad, newt, lizard or snake in your garden, on a walk, crossing the road – in fact any where! – make a note of what it was, where it was and if possible get a picture.  You can then input the details online here (which only takes a couple of minutes) and….voila!  Suddenly there are more records about the distribution of these species.  This is particularly useful data to have, especially when we’re facing climate change, as it allows us to monitor populations and distributions, and hopefully pick up changing patterns more quickly.

We had an excellent turn out to the training course and everyone really enjoyed the days – and have gone away eager to start surveying and recording these important species.  One of the highlights of the event had to be the excellent views of an adder, which was many peoples first sighting.  Some people were lucky enough to see a grass snake too, and fortunately the weather stayed dry enough to make surveying for amphibians, in a pond, by torchlight possible.

A big thank you goes out to ARC-trust for providing the training and to NWWT for looking after Gwaith Powdwr so well, making it an excellent location for training people in surveying techniques.  We’re hoping to arrange future surveying events so if you fancy getting involved, keep and eye on our website, or contact us to be added to our mailing list.

O ddallnadroedd cysglyd a gwiberod yn torheulo i ddigonedd o fadfallod y dŵr – gwelwyd pob un ohonynt yr wythnos diwethaf!

Cawsin ddau ddiwrnod anhygoel yr wythnos diwethaf!  Fe wnaeth Cymdeithas Eryri gydweithio ag Ymddiriedolaeth Bywyd Gwyllt Gogledd Cymru (NWWT) a’r Ymddiriedolaeth Gwarchod Amffibiaid ac Ymlusgiaid i gynnal hyfforddiant ynghylch gwneud arolygon o amffibiaid ac amlusgiaid.  

Wyddoch chi nad oes digon o waith cofnodi amffibiaid a reptiliaid o bell ffordd yn digwydd yn y DU?  A wyddoch chi y gallwch newid hynny?  Os gwelwch lyffant, brogfa, madfall y dŵr, madfall neu neidr yn eich gardd, yn ystod taith gerdded, wrth groesi'r ffordd - yn wir, yn unrhyw fan! – cadwch gofnod o’r math o anifail, ble’r oedd a thynnwch lun os gallwch.  Yna, gallwch nodi’r manylion ar-lein yma a….voila!  Yn sydyn, mae rhagor o gofnodion o ddosbarthiad y rhywogaethau hyn.   Mae'r data hyn yn ddefnyddiol iawn, yn enwedig â ninnau’n wynebu newid yn yr hinsawdd, oherwydd mae'n caniatáu inni fonitro poblogaethau a dosbarthiadau, a chanfod patrymau newidiol yn gyflymach, gobeithio.

Cawsom bresenoldeb rhagorol ar y cwrs ac fe wnaeth pawb fwynhau’r ddau ddiwrod yn fawr. Maent oll wedi mynd ati’n frwdfrydig i gychwyn arolygu a chofnodi’r rhywogaethau pwysig hyn.  Un o uchafbwyntiau’r digwyddiad heb os oedd y golygfeydd rhagorol o wiber, y tro cyntaf i lawer o bobl weld un.  Bu rhai pobl yn ddigon ffodus i weld neidr y glaswellt hefyd, ac yn ffodus, roedd y tywydd yn ddigon sych i alluogi inni wneud arolygon o amffibiaid, mewn pwll, dan olau torsh.

Diolch yn fawr i’r Ymddiriedolaeth Gwarchod Amffibiaid ac Ymlusgiaid am ddarparu’r hyfforddiant ac i NWWT am ofalu am warchofa Gwaith Powdwr mor dda, gan sicrhau ei fod yn leoliad gwych i ddarparu hyfforddiant mewn technegau gwneud arolygon.  Rydym yn gobeithio trefnu digwyddiadau arolygu yn y dyfodol, felly os oes arnoch awydd cyfranogi, cofiwch gadw llygaid ar ein gwefan, neu e-bostiwch i ychwanegu eich enw at ein rhestr bostio.

Thank you Gwirvol! Diolch Gwirvol!

Thank you Gwirvol!

The Snowdonia Society, were lucky enough to secure funding from Gwirvol from last April, to enable us to provide transport for young volunteers aged 14-25 to allow them to attend workdays.  Transport in a rural area such as Snowdonia can be a real barrier to volunteering and the money from Gwirvol has allowed over 40 young people to get involved in our workdays.  Young people from a variety of backgrounds have taken part in a number of tasks ranging from controlling invasive species such as Himalayan balsam and Rhododendron to footpath maintenance, scrub clearance and tree planting.  

Katie is a volunteer from Bangor University who has benefited from the transport provided for workdays.  Katie says “the workdays are held regularly and provide a valuable opportunity for students and community members alike to gain skills and knowledge in a practical sense that is not always available at a class room level.  I look forward to future events and believe that these skills gained will assist me in my future endeavours.”

Katie first volunteered with the society in October, where she attended a bioblitz at Ty Hyll, the Snowdonia Society’s property near Betws y Coed. A Bioblitz is where volunteers and experts come together to record as many species as possible, whilst giving volunteers the opportunity to learn new skills such as moth, fungi and plant identification. Transport was provided allowing Katie and other young volunteers to access the site easily.  Over the weekend, informal training in plant identification was given to young volunteers by a local expert as well as volunteers having the opportunity to foray for fungi, hunt for frogs and toads and identify moths with the help of experts.  On the day a very rare fungi was found, as well as a plant species which was new to the site.  Overall a successful weekend!

More recently, Katie attended a tree planting workday with the society, again at Ty Hyll.  Below is her account of the day:

'The day first appeared as one that may become unfavourable to those who chose to spend this Sunday morning getting their hands dirty in the name of conservation. But! Our nature seeking hearts remained full as we were graciously chauffeured to the most beautiful 'Ugly House' to meet our fellow brave supporters. The turn out was impressive and the right gear was chosen. We were briefed with our tree planting duties and encouraged for our passion and resilience against the elements as we geared up with shovels, guards, and an assortment of young saplings, itching to find a new home. We were led by the infamous Margaret; an inspiring veteran with 20 years of service. Placement is everything and she held the knowledge and intuition that allows our digging to be made worthwhile. Jenny was also on our side particularly as we faced onsets of hail, rain and finally sunshine. All members were of great importance and an integral part of our experience. The trees were planted, alongside a class of worthy winter tree identification and the feeling of accomplishment began to overwhelm us. Our ride was reliably waiting and I left feeling light and happy. These volunteer days are invaluable to both its participants and the earth'

The Snowdonia Society would like to take this opportunity to thank Gwirvol, on behalf of all our young volunteers, for the funding which has allowed us to make such a difference to young volunteers in this area.  Katie’s is just one of the positive stories which has come about because of the funding, young people have been able to access volunteering opportunities which would have been difficult/ impossible for them to without the provision of transport.  Thank you Gwirvol!

Diolch Gwirvol!

Bu Cymdeithas Eryri yn ddigon ffodus i gael arian gan Gwirvol fis Ebrill diwethaf i ganiatáu inni ddarparu cludiant i wirfoddolwyr ifanc 14-25 i alluogi iddynt fynychu ein diwrnodau gwaith.  Gall cludiant mewn ardal wledig megis Eryri fod yn rhwystr go iawn rhag gwirfoddoli, ac mae arian Gwirvol wedi caniatáu i dros 40 o bobl ifanc gyfranogi yn ein diwrnodau gwaith.  Mae pobl ifanc o gefndiroedd amrywiol wedi cymryd rhan mewn nifer o ddiwrnodau gwaith yn amrywio o reoli rhywogaethau ymwthiol megis Ffromlys Chwarennog a Rhododendron i gynnal a chadw llwybrau troed, clirio prysgwydd a phlannu coed.  

Mae Katie yn wirfoddolwraig o Brifysgol Bangor sydd wedi elwa ar y cludiant a drefnir ar gyfer diwrnodau gwaith.  Dywed Katie: “caiff y diwrnodau gwaith eu cynnal yn rheolaidd ac maent yn gyfle gwerthfawr i fyfyrwyr ac aelodau’r gymuned i feithrin sgiliau a gwybodaeth mewn ystyr ymarferol ac nid yw hynny bob amser ar gael yn yr ystafell ddosbarth.  Edrychaf ymlaen at ddigwyddiadau’r dyfodol, a chredaf y gwnaiff y sgiliau a gefais fy nghynorthwyo â fy ymdrechion yn y dyfodol.”

Fe wnaeth Katie gychwyn gwirfoddoli i’r Gymdeithas ym mis Hydref, pan fynychodd y Bioblitz yn Nhŷ Hyll, eiddo Cymdeithas Eryri ger Betws y Coed. Mae Bioblitz yn gynulliad o wirfoddolwyr ac arbenigwyr er mwyn cofnodi cymaint ag y bo modd o rywogaethau, gan roi cyfle i wirfoddolwyr ddysgu sgiliau newydd megis adnabod gwybed, ffyngau a phlanhigion. Darparwyd cludiant, a alluogodd i Katie a gwirfoddolwyr ifanc eraill deithio’n rhwydd i’r safle.  Dros y penwythnos, rhoddwyd hyfforddiant anffurfiol mewn adnabod planhigion i bobl ifanc gan arbenigwr lleol, a chafodd gwirfoddolwyr gyfle i chwilio am ffyngau, hela llyffantod a brogaod ac adnabod gwybed â chymorth arbenigwyr.  Canfuwyd ffwng prin iawn ar y diwrnod, yn ogystal â rhywogaethau planhigion oedd yn newydd i’r safle.  Penwythnos llwyddiannus ar y cyfan!

Yn fwy diweddar, daeth Katie i weithdy plannu coed a drefnwyd gan y Gymdeithas, unwaith eto yn Nhŷ Hyll.  Mae ei disgrifiad o’r diwrnod isod:

‘Yn y lle cyntaf, ymddangosai’r diwrnod fel un a allai ddod yn anffafriol i’r sawl sy’n dymuno treulio eu bore Sul yn baeddu eu dwylo wrth wneud gwaith cadwraeth. Ond! Codwyd ein calonnau ceisio natur wrth inni gael ein hebrwng yn garedig i’r ‘Tŷ Hyll’ prydferth iawn i gwrdd â’n cefnogwyr dewr. Roedd y presenoldeb yn drawiadol a dewiswyd yr offer priodol. Cawsom eglurhad o’n dyletswyddau plannu coed a chawsom ein hannog i fod yn frwdfrydig a gwydn yn erbyn yr elfennau wrth inni fynd i’r afael â rhawiau, amddiffynwyr ac amrywiaeth o lasbrennau ifanc oedd yn ysu i ganfod cartref newydd. Cawsom ein harwain gan Margaret, gwirfoddolwraig ysbrydoledig sydd â dros 20 mlynedd o wasanaeth. Mae gwybod lle i osod y planhigion yn hollbwysig ac roedd ganddi’r wybodaeth a’r sythwelediad a sicrhaodd fod ein cloddio yn werth chweil. Roedd Jenny hefyd o’n plaid wrth inni wynebu cenllysg, glaw, ac yn olaf, heulwen. Roedd yr holl aelodau yn bwysig iawn ac yn rhan anhepgor o’n profiad. Plannwyd yr holl goed, a chafwyd dosbarth adnabod coed yn y gaeaf, ac fe wnaeth teimlad o fod wedi llwyddo gychwyn ein gorlethu. Roedd ein cludiant yn ein haros a gadewais yn teimlo’n ysgafn a llawen. Mae’r diwrnodau gwirfoddoli yn amhrisiadwy i’r cyfranogwyr a’r ddaear’

Hoffai Cymdeithas Eryri elwa ar y cyfle i ddiolch i Gwirvol, ar ran ein gwirfoddolwyr ifanc, am yr arian sydd wedi caniatáu inni wneud cymaint o wahaniaeth i wirfoddolwyr ifanc yn yr ardal.  Mae hanes Katie yn un yn unig o’r straeon positif sydd wedi deillio o’r cyllid. Mae pobl ifanc wedi llwyddo i elwa ar gyfleoedd gwirfoddoli a fyddai wedi bod yn anodd neu’n amhosibl iddynt heb ddarparu cludiant.  Diolch Gwirvol!

Plas y Brenin's Climbing Wall

We could have been out Christmas shopping but instead we were treated to rock climbing for beginners, indoors on the wall at Plas y Brenin. Not so much a wall as a cavernous chamber with overhangs and arches. Brendan and his two colleagues kitted us out with climbing shoes, helmets and harnesses; the shoes were a bit tight but that’s all part of the design, for greater grip.

We began with basic bouldering, low down on the wall going crab-like across. Legs are stronger than arms so we were advised to maximise the use of legs as opposed to arms. Arms at full stretch are stronger than arms crunched up so we tried to keep them long. Theory is easy but handholds and toeholds didn’t always present themselves where they needed to be.


After free climbing a low section we roped up, climbed the high bits then belayed down. Bit of an act of faith, to let go of those handholds that had been squeezed so tight on the way up, and lie back at right angles to the wall. The wall with the overhangs proved a bit too challenging for me and I found myself spinning in space, safely held by the rope which we were assured was strong enough to hold a minibus.

A huge thank you to Plas y Brenin for supporting the Snowdonia Society as a business member and laying on this event.  What I hadn’t realised before was that this wonderful climbing wall is open to us locals; I think the charge is just £5.

Dorothea a Trigonos

For our winter social 26 of us were treated to a guided walk around Dorothea slate quarry, a fascinating insight from Dr Gwynfor Pierce Jones. Some members of the group remembered the good old days, when it was possible to abseil a hundred metres to the bottom of the pit before it filled up with water.

From the start, Gwynfor sought to be controversial for fear we might not remember him; no chance of that, but I won’t repeat things for fear of libel. For anyone wanting to know more about Dorothea, the recommended website is penmorfa.com There is of course Gwynfor’s book but make sure you buy the new edition which is becoming available just now.

Back at Trigonos we enjoyed a tasty home cooked lunch; a great venue, with superb views and good company.

In the footsteps of Augustus John – some miraculous promised land

2014 marks the centenary of the death of James Dickson Innes, who along with Augustus John and Derwent Lees produced some of the most dramatic and expressionistic landscape painting of the 20th century. Between 1910 - 1913 these three artists rented a cottage at Nant Ddu, near Llyn Tryweryn to paint landscapes around Arenig and the surrounding moorland, a landscape Augustus John described as 'some miraculous promised land'.

The walk and talk event that the Snowdonia Society has arranged on 22nd February will visit some of the places that inspired these artists. If the weather is clear and bright there will be a choice of two walks on offer, both of which will begin and end at Nant Ddu. The more challenging walk, which will only take place if the weather is reasonably clear, will follow a route up Arenig via Amnodd Bwll returning via Llyn Arenig and the old railway trackbed. This walk will take approximately 5 hours, involve some steep sections and require a high level of fitness.

The other walk will be much easier and be on fairly level terrain. It will also start at Nant Ddu and visit Llyn Tryweryn and Blaen Cwm Prysor before returning along the abandoned railway trackbed. This walk will take approximately 2½ hours. Both walks will provide opportunities to view copies of work produced by these artists and share views about the landscape that inspired them.

The walks are open to all with a suggested donation of £5 or, for members of the Society, a donation of £3. To make a booking please contact info@snowdonia-society.org.uk

The walk is being organised and led by Gareth Roberts. Trained as an art historian, geographer and planner, Gareth has worked with the Snowdonia National Park Authority and the Countryside Council for Wales. He is a Director of the Landscape Research Group Ltd. and supports the work of charitable organisations involved in the conservation and enhancement of cultural landscapes internationally.

Engaging with Ecosystems

**Scroll down for Welsh**  **Rholiwch i lawr i weld y testun Cymraeg**

What a fantastic evening we had last night at our “Engaging with Ecosystems talk”.   The main focus of the evening was the invasive species Rhododendron ponticum.

-  Did you know that there are over 1000 species of Rhododendron worldwide and Rhododendron ponticum is the only invasive one? 

- Did you know that it is a myth that the Victorians introduced Rhododendron ponticum to the UK?  It was in fact found here naturally before the last ice age but didn’t re-colonise.  It was then introduced by the Georgians around 1763!

- Did you know that it is extremely toxic and even honey produced from Rhododendron ponticum can be poisonous for humans, causing, among other things, heart problems?

The evening started with an introduction to Pensychnant Conservation Centre, where the event was held.  Julian Thomson, Pensychnant manager, outlined a brief history of the house and grounds and then told us about the way they have tackled Rhododendron there. 

Mary-Kate, project manager for the Snowdonia Society then introduced the concept of ecosystem services to the group.  Put simply, ecosystem services are the resources produced by the environment which humans use.  Examples would include clean air, pollination, flood control, Carbon sequestration and tourism.  Many of the Snowdonia Society workdays directly contribute towards maintaining or improving ecosystem services.  Footpath maintenance ensures that visitors to the area can safely enjoy Snowdonia while Himalayan balsam removal prevents native species from being out competed; both in terms of space and light and for pollinators.

Finally, Carwyn ap Myrddin of Snowdonia National Park Authority went into detail about large scale Rhododendron ponticum control in Snowdonia.  It’s a real problem as its thick branches block all light from reaching the ground, so it out-competes our native species.  It is also very toxic, making grazing as a control method difficult, and releasing toxins back into the soil, making re-colonisation by native species a challenge.  Each plant releases millions of seeds meaning that once established it is very difficult to get rid of!  It is estimated that it would cost £10 million to eradicate Rhododendron ponticum from Snowdonia.   Snowdonia National Park Authority, Natural Resources Wales (NRW) and the National Trust have teamed up to tackle Nant Gwynant, a key problem area for this plant – hopefully in the future tourists will be coming to see slopes full of native plants with not  a rhododendron in sight!

A big thank you goes out to Carwyn and Julian for sharing their expertise with us, and also to everyone who turned up to take part!

If you would like to get involved with some of the Snowdonia Society’s workdays, including Rhododendron ponticum control, check out our opportunities here.

Ymgysylltu ag Ecosystemau

Cawsom noson wych neithiwr yn ein sgwrs am "Ymgysylltu ag Ecosystemau".   Prif sylw’r noson oedd y rhywogaeth ymwthiol Rhododendron ponticum.

-  Wyddoch chi fod dros 1000 rhywogaeth Rhododendron ledled y byd a Rhododendron ponticum yw’r unig un yw’r unig un ymwthiol? 

- A wyddoch chi mai myth yw’r gred mai’r Fictoriaid a gyflwynodd Rhododendron ponticum yn y DU?  Mewn gwirionedd, roedd yma’n naturiol cyn oes yr ia diwethaf ond ni wnaeth ail-gytrefu.  Yna, fe’i cyflwynwyd gan y Sioriaid tua 1763!

- A wyddech chi ei fod yn hynod wenwynig a gall hyd yn oed mêl a gynhyrchir o Rhododendron ponticum fod yn wenwynig i bobl, gan achosi problemau’r galon ymysg pethau eraill?

Cychwynnodd y noson â chyflwyniad i Ganolfan Cadwraeth Pensychnant, ble cynhaliwyd y digwyddiad.  Fe wnaeth Julian Thomson, rheolwr Pensychnant, amlinellu hanes cryno’r tŷ a’r gerddi, ac yna fe wnaeth egluro inni sut maent wedi taclo Rhododendron yno. 

Yna, fe wnaeth Mary-Kate, rheolwr prosiect Cymdeithas Eryri, gyflwyno’r cysyniad o wasanaethau ecosystem i’r grŵp.  Yn syml, gwasanaethau ecosystem yw’r adnoddau a gynhyrchir gan yr amgylchedd a ddefnyddir gan bobl.  Mae enghreifftiau yn cynnwys awyr iach, peillio, rheoli llifogydd, dal a storio carbon, a thwristiaeth.  Mae llawer o ddiwrnodau gwaith Cymdeithas Eryri yn cyfrannu’n uniongyrchol at gynnal neu wella gwasanaethau ecosystem.  Mae cynnal llwybrau troed yn sicrhau fod ymwelwyr sy'n dod i'r ardal yn gallu mwynhau Eryri yn ddiogel ac mae clirio Ffromlys Chwarennog yn sicrhau nad yw rhywogaethau cynhenid yn gorfod cystadlu yn eu herbyn am le, goleuni a phryfed peillio.

Yn olaf, fe wnaeth Carwyn ap Myrddin o Awdurdod Parc Cenedlaethol Eryri roi cyflwyniad manwl am reoli Rhododendron ponticum ar raddfa helaeth yn Eryri.  Mae’n broblem sylweddol, oherwydd mae ei ganghennau trwchus yn atal unrhyw oleuni rhag cyrraedd y ddaear, felly bydd yn drech na'n rhywogaethau cynhenid.  Mae’n wenwynig iawn hefyd, sy’n golygu ei bod hi'n anodd defnyddio pori i'w reoli, a bydd yn rhyddhau tocsinau i'r pridd, sy'n golygu fod ail-gytrefu gan rywogaethau cynhenid  yn her.  Bydd pob planhigyn yn gollwng miliynau o hadau, sy'n golygu ei fod yn anodd iawn cael gwared arno wedi iddo sefydlu!  Amcangyfrifir y buasai difa Rhododendron ponticum  yn llwyr yn Eryri yn costio £10 miliwn.   Mae Awdurdod Parc Cenedlaethol Eryri, Cyfoeth Naturiol Cymru (CNC) a’r Ymddiriedolaeth Genedlaethol wedi dod ynghyd i’w daclo yn Nant Gwynant, un o’r mannau lle mae’r planhigyn hwn yn fwyaf problemus - gobeithio y gall twristiaid y dyfodol ddod i weld y llethrau yn llawn planhigion cynhenid, heb unrhyw rododendron i'w gweld!

Diolch yn fawr iawn i Carwyn a Julian am rannu eu harbenigedd â ni, a diolch hefyd i bawb a ddaeth draw i gyfranogi.
