After it was first discovered in Gwynedd in December 2021, the pathogen Phytophthora pluvialis has now been confirmed at a further two sites in Wales – in Crychan, Llandovery and south of the original site in Dyfi forest.
P. pluvialis is know to affect Douglas fir and several pine species, causing needle cast, shoot dieback and lesions on the stem, branches and roots.
To understand the extent of the spread, Natural Resources Wales are surveying the area and will introduce a demarcated area around the site of the original finding on 26 January to restrict the movement of materials capable of spreading the disease.
We urge members across the UK to report any possible sightings of the disease via the TreeAlert online portal.
