FURTHER findings of a new tree disease have been confirmed in the south west of England. 

Forestry Commission chiefs have said demarcated areas in Cornwall and Devon will be extended following discovery of the pathogen Phytophthora pluvialis.

Additional restrictions requiring pre-notification of felling of susceptible material will also be introduced from December 10 in the counties and in Cumbria.

The disease, which was first discovered in Europe in September, has so far been confirmed in more than 10 sites across the UK, including in the north west of Scotland. 

A notice from the Forestry Commission reads: "The Notices prohibit the movement of any wood, isolated bark and trees (including live trees, felled or fallen trees, fruit, seeds, leaves or foliage) of the genus Tsuga, Pseudotsuga, Pinus and Notholithocarpus, that has originated within the demarcated area.

"Provision is made within the Notices to enable plant health inspectors to authorise movements and processing of material from the demarcated area where this can be achieved without risking the spread of Phytophthora pluvialis.
