About Phytophthora Austrocedri:
The impact of the pathogen is currently limited in the UK as a whole. However, it is potentially serious for the Upper Teesdale juniper. This is because these are rare plants and this site has the second largest population of the species in the UK. Common juniper is already known as important and vulnerable, because since about 1990 its extent and condition have declined considerably. Juniper is also a key food plant for a wide range of invertebrates and birds, which means it has a unique and specialised group of associated insects, fungi and lichens. The establishment of P. austrocedri in the UK could further contribute to its decline.
