1 Newyddion Gwylio Dolffiniaid 2010 Dolphin Watch News Bu n dipyn o flwyddyn ers y cylchlythyr diwethaf. Bu r gwirfoddolwyr allan ar bum safle r Haf diwethaf; bu ymgynghori mawr ynghylch rheoli cychod hamdden a bywyd gwyllt a lluniwyd cynllun; bu cwch patrôl yr Ardal Gadwraeth Arbennig yn brysur ar y môr; cafodd gwerth dau dymor o ddata ynglŷn â gwylio dolffiniaid ei ddadansoddi a lluniwyd adroddiad; ac ar ben hyn i gyd daeth mwy o bobl nag erioed o r blaen i r ganolfan wybodaeth, Man Cychod Bae Ceredigion! Mae prosiect Gwylio r Dolffiniaid wedi bod yn casglu data ers 15 mlynedd bellach o safleoedd yn ne Ceredigion. Y Cyngor sy n gyfrifol am y prosiect a r un yw r prif nod: (a) monitro dolffiniaid trwynbwl mewn nifer o safleoedd oddi ar yr arfordir; a (b) casglu data ynghylch traffig cychod i helpu rheoli cychod yn y Bae. Cafodd yr astudiaeth ei chynllunio i annog y bobl leol i gymryd rhan ac i godi ymwybyddiaeth ynglŷn â r problemau y mae cychod yn gallu eu hachosi. Well what a year it s been since our last newsletter. Volunteers were out at five sites last summer; a major consultation was held about managing recreational boating around wildlife and a plan produced; the SAC patrol boat was busy out on the water; two seasons of Dolphin Watch data were analysed and a report produced; and to cap it all, record numbers of visitors at our marine information centre, the Cardigan Bay Boat Place! The Dolphin Watch project has now completed 15 years of data gathering from sites in southern Ceredigion. The principal aims of this Council-run project remain the same: (a) to monitor the presence of bottlenose dolphins at a number of coastal sites; and (b) gather data on boat traffic to aid management of boating activity in the Bay. The study was designed in such a way to encourage local people to take part and to raise public awareness of the issue of boat disturbance.

2 2 Newyddion Gwylio Dolffiniaid 2010 Dolphin Watch News lyn 8/2 at Y r yn rhy rw i r ilidowcar bys ta! A yw hi n Haf o r diwedd!? Bu 557 o wyliadau ar y tir mewn tywydd cymysg ym Mwnt, Aber-porth, Ynys Lochtyn, Craig yr Aderyn Ceinewydd a Harbwr y Ceinewydd rhwng mis Mehefin a mis Medi y llynedd. Yn anffodus nid oedd data Harbwr y Ceinewydd ar gael pan wnaed y dadansoddiad (Ionawr 2010). Roedd cyfraddau gwylio r Dolffiniaid a maint y grwpiau ychydig yn is nag oeddynt y flwyddyn flaenorol. Gwelwyd y grwpiau mwyaf ar gyfartaledd ym Mwnt a oedd yn fwy o lawer na r grwpiau ger Craig yr Aderyn ger y Ceinewydd. Yn 2009, roedd maint grwpiau r dolffiniaid ym Mwnt a Harbwr y Ceinewydd lawer yn fwy nag oeddynt yn Aberporth. Roedd cyfartaleddau Mwnt a r Ceinewydd lawer yn uwch nag Aberporth a Chraig yr Aderyn ger y Ceinewydd. Cofnodwyd 739 o gyfarfyddiadau rhwng dolffiniaid trwynbwl a chychod yn ystod 2008 a 2009, ac roedd y gyfradd uchaf o ran cyfarfyddiadau bob awr i w cael yn Harbwr y Ceinewydd yn Fel y blynyddoedd blaenorol, gwelwyd bod gwahaniaethau amlwg yn lefelau traffig y cychod rhwng Harbwr y Ceinewydd a safleoedd eraill. Ym Mwnt unwaith yn rhagor y gwelwyd traffig y cychod ar ei isaf. Roedd rhywfaint o dystiolaeth bod lefelau traffig y cychod yn dychwelyd i r lefelau a oedd yn bodoli cyn y gostyngiad yn y traffig hwnnw a welwyd yn 2007, fel yn y Ceinewydd, ond prin oedd y dystiolaeth o gynnydd dros gyfnod lt of t 8/2 at Se to roug for corm ra ts to fis! Summer at last!? An impressive 557 land-based watches were undertaken in mixed weather conditions at Mwnt, Aberporth, Ynys Lochtyn, New Quay Birds Rock and New Quay Harbour between June & September last year. Unfortunately, 2008 New Quay Harbour data wasn t available at the time of analysis (January 2010). Dolphin sighting rates and group size were slightly down to the previous year. The average group size was largest at Mwnt, and was significantly larger than at New Quay Birds Rock. In 2009, dolphin group size at Mwnt and New Quay Harbour was also significantly larger than at Aberporth. Mwnt and New Quay Harbour average counts were significantly higher than both Aberporth and New Quay Birds Rock. A total of 739 bottlenose dolphin encounters with boats were recorded during 2008 and 2009, with the highest observed encounter rate per hour at New Quay Harbour in As in previous years, clear differences in levels of boat traffic were evident between New Quay Harbour and other sites. Mwnt again had the least boat traffic. There was some evidence of a return of boat traffic to levels before the reduction in traffic in 2007, such as at New Quay, but little evidence of

Pwrpas yr ymgynghori oedd gofyn barn pobl ynglŷn â ph un ai a oedd y mesurau rheoli cychod wedi gweithio n dda ac a oedd angen newid pethau o gwbl. Dychwelwyd 36 o holiaduron i gyd ac fe gynhaliwyd 11 o gyfarfodydd un i un gyda chyrff allweddol. Roedd ymwybyddiaeth uchel o Ardal Gadwraeth Arbennig Bae Ceredigion ymhlith y rhai a ymatebodd sef 100% ac roedd 71% o r ymatebwyr wedi nodi bod ganddynt fuddiannau o ran cychod hamdden. Sustainable boating in Cardigan Bay Response to consultation Last year the Coast & Countryside Section wrote to all boat clubs, diving groups and coastal town/community councils as part of a major consultation of skippers and recreational boat users of the Ceredigion coastline. The purpose of the consultation was to seek views on what boating management measures had worked well and what, if anything, needed changing. A total of 36 questionnaires were returned and 11 one-to-one meetings held with key organisations. Awareness of the Cardigan Bay Special Area of Conservation (SAC) amongst respondents was very high at 100% and the percentage of respondents listed as having a recreational boating interest was 71%.

Would you like to see a standard code that applies to the whole of Wales? 76 A oes angen cod neilltuol ar gyfer Ceredigion (i amlygu ardaloedd arbennig o sensitif, er enghraifft)? Does Ceredigion still need its own specific code (to highlight particularly sensitive areas, for example)? 66 A oes angen codau gwahanol ar gyfer cychod masnachol a chychod hamdden? Do commercial trip boats need a separate code to recreational boats? 27 A oes angen cod neilltuol ar gyfer unrhyw weithgareddau (caiacio, pysgota, cychod modur ac ati)? (Os oes, nodwch y gweithgareddau?) Do any activities (kayaking, angling, powerboating etc) require a specific code? (if yes, please specify which activities) 44

O ganlyniad i r data a gasglwyd dros y blynyddoedd, ac yn dilyn yr ymgynghori cyhoeddus y llynedd, lluniwyd cynllun cychod hamdden ar gyfer Ceredigion ac mae n cynnig sail ar gyfer rheoli at y dyfodol. Mae r cynllun yn amlinellu sut yr ydym am gynnal y dull gwirfoddol presennol o reoli a dal ati i roddi gwybodaeth i gapteiniaid a datblygu eu cyfranogiad. Bydd y Cyngor yn cynnal ei bolisi o dynnu cyfleusterau angori/lansio oddi ar gapteiniaid os na fyddant yn cydymffurfio â r Cod a datblygu cyfranogiad y clybiau cychod o ran rhoi gwybod inni os caiff y cod ei dorri. Caiff yr ardal cyflymder 8 not rhwng Pentir Ceinewydd ac Ynys Lochtyn ei hymestyn hyd ardal yr is-ddeddfau yn Llangrannog a bwriadwn gyflwyno canllaw cyflymder 8 not o fewn 200 metr i r glannau rhwng pentir Aber-porth ac Ynys Aberteifi. Y bwriad yw gwarchod y pentiroedd y gwyddom eu bod yn safleoedd pwysig lle mae dolffiniaid yn cael eu bwyd, ac mae r ardal sydd gyda r glannau n bwysig o ran adar y môr. Yr ydym bellach yn gwybod mwy o ran pa ardaloedd sydd bwysicaf i fywyd gwyllt, ac o r herwydd mae mwy o gyfleoedd i hybu gweithgareddau cychod mewn rhai ardaloedd, ar yr amod bod cyfleusterau lansio addas ar y A boating plan for Ceredigion The Dolphin Watch project underpins all the work that the Council is doing on managing recreational boating activity. As a direct result of the data gathered over the years, and following last year s public consultation, a recreation boating plan for Ceredigion has been produced which provides the basis for future management. The plan outlines how we are going to maintain the current voluntary management approach and continue to provide information to skippers and develop their involvement. The Council shall continue the policy of withdrawing mooring/launching facilities from skippers that habitually fail to comply with the Code and develop involvement of boat clubs in reporting breaches. The existing 8 knot speed zone between New Quay Head and Ynys Lochtyn will be extended to the bye-law area at Llangrannog and we plan to introduce 8 knot speed guidance within 200 metres from shore between Aberporth headland and Cardigan Island. This is designed to help protect those headlands that we know are important feeding areas for dolphins, and the inshore area that is so important for breeding seals and seabirds. Now that we know more about which areas are most important for wildlife, there are opportunities to promote boating activity in some areas, subject to suitable on-shore 300m 100m 100m 50m Cadwch allan Isafswm cyflymder a sŵn.

8 8 Newyddion Gwylio Dolffiniaid 2010 Dolphin Watch News Straeon Jean.... Mae Jean Bryant, sy n un o Wylwyr y Dolffiniaid yng Ngwylfa Craig yr Aderyn ers 1994, wedi cofnodi llawer o straeon am y gwahanol adar ac anifeiliaid y mae hi a i diweddar ŵr Alan wedi eu trin yn ysbyty Adar Ceinewydd dros y blynyddoedd. Dyma stori r morlo bach du a aeth yn sownd Daeth galwad gynnar cyn brecwast o r Ceinewydd i ddweud d bod yna rywbeth byw yn un o r pibelli mawr ger y ffatri bysgod. Aethom yno a chanfod bod morlo bach wedi mynd yn sownd yn y bibell! Gafaelodd Alan yn ei adenydd blaen a dechreuodd dd ei dynnu allan yn araf. Daeth allan megis corc ac roedd yn ddu loywddu drosto; morlo bach hardd a llygaid mawr ganddo. Dyma r ail forlo cwbl ddu i ni ei weld..dywedir di eu bod yn cael eu geni o bryd i w gilydd. Ar ôl iddo gael nofio a chael macrell wedi ei fwydo â llaw, daeth ato ei hun ac fe gafodd ei ryddhau n ddiweddarach. Jean s tales.... Jean Bryant, Dolphin Watcher at the Birds Rock Lookout since 1994, has recorded many stories of different birds and animals that she and her late husband Alan have treated at their New Quay Bird Hospital over the years. Here s her tale of the stuck black seal pup An early call before breakfast from New Quay to report rt something alive up one of the large pipes p being sorted out near the fish factory. Off we went to find a seal pup p had gone up the pipe p and got stuck! Alan took hold of its front flippers and began to pull slowly. He came out like a cork and was jet black all over; a lovely pup with huge eyes. This was the second all black seal pup p we had seen. It does happen occasionally we re told. After a swim and hand fed mackerel, he behaved normally and was released later. Diolch yn fawr 4 I r gwylwyr sy n rhoi o u hamser mor hael 4 I gydlynwyr y safleoedd lleol am sicrhau bod y gwaith yn mynd rhagddo n dda: Juliet Owen; Peter Pimblett; Penny Sharp a Sarah Perry. 4 I Ymddiriedolaeth Bywyd Gwyllt De a Gorllewin Cymru a Chanolfan Bywyd Gwyllt Morol Bae Ceredigion am eu diddordeb a u cyfranogiad 4 I Gyngor Cefn Gwlad Cymru am eu cymorth ariannol tuag at Wylio r Dolffiniaid 4 I Gronfa Stiwardiaeth Forol Stad y Goron am eu cymorth ariannol tuag at y Cynllun Rheoli Cychod Hamdden Ac yn olaf, 4 I r holl gapteiniaid sy n dilyn y cod ymddygiad ac yn cyfrannu at ddiogelu Bae Ceredigion.
