Phytophthora pluvialis can affect a variety of tree species, including western hemlock, Douglas fir and several pine species \- the first Welsh finding was confirmed in Gwynedd last month.


A second finding has now been confirmed at a site in Crychan, Llandovery while a third finding has been confirmed to the south of the original site in Dyfi forest.  

Natural Resources Wales is undertaking surveys in these areas to understand the extent of the spread.


It is reported to cause needle cast \- where needles turn brown and fall off – as well as shoot dieback and lesions on the stem, branches and roots.


Phytophthora pluvialis had already been discovered in parts of England and Scotland before it was confirmed to be in Wales.


As the disease has never been detected in Europe before, research is ongoing to understand if other potentially susceptible species could become impacted. 


This will help inform which control measures are appropriate and the potential impact this pathogen could have on the landscape and the forestry sector.


To protect the country against this pathogen and to limit the potential spread of this disease, the Welsh Government will introduce a demarcated area around the site of the original finding to restrict the movement of materials capable of spreading the disease. 


A notice will come into force on 26 January.


A symptom guide has been prepared that provided more information on Phytophthora pluvialis.


People are urged to report sightings via the TreeAlert online portal.

Gall Phytophthora pluvialis effeithio ar amrywiaeth o rywogaethau coed, gan gynnwys hemlog y gorllewin, ffynidwydd Douglas a sawl rhywogaeth o binwydd – a chadarnhawyd yr achos cyntaf yng Nghymru yng Ngwynedd fis diwethaf.


Mae ail achos bellach wedi cael ei gadarnhau ar safle yng Nghrychan, Llanymddyfri, ac mae trydydd achos wedi cael ei gadarnhau i'r de o'r safle gwreiddiol yng Nghoedwig Dyfi.


Mae Cyfoeth Naturiol Cymru yn cynnal arolygon yn yr ardaloedd hyn i ddeall pa mor bell mae’r clefyd wedi lledaenu.


Mae’r clefyd yn arwain at fwrw nodwyddau – lle mae nodwyddau'n troi'n frown ac yn syrthio i’r llawr – yn ogystal ag at egin yn marw ac at friwiau ar y boncyff, y canghennau a’r gwreiddiau.


Roedd Phytophthora pluvialis eisoes wedi cael ei ganfod mewn rhannau o Loegr a'r Alban cyn i’r achosion yng Nghymru gael eu cadarnhau.


Gan nad yw'r clefyd erioed wedi cael ei ganfod yn Ewrop o'r blaen, mae ymchwil yn parhau i ddeall a fyddai’n bosibl i’r clefyd effeithio ar rywogaethau eraill.


Bydd hyn yn helpu i nodi pa fesurau rheoli sy'n briodol a'r effaith bosibl y gallai'r pathogen hwn ei chael ar y dirwedd a'r sector coedwigaeth.


Er mwyn diogelu'r wlad rhag y pathogen hwn a’i atal rhag lledaenu, bydd Llywodraeth Cymru yn pennu ardal o amgylch y safle lle y cafodd y clefyd ei ganfod gyntaf, i gyfyngu ar symud deunyddiau sy'n gallu lledaenu'r clefyd. 


Daw hysbysiad i rym ar 26 Ionawr.


Mae canllaw symptomau wedi cael ei baratoi sy’n rhoi rhagor o wybodaeth am Phytophthora pluvialis.


Anogir pobl i roi gwybod os ydyn nhw’n gweld achos o’r clefyd drwy borth ar\-lein TreeAlert.
