Susceptibility of native Scots pine (Pinus sylvestris) to Dothistroma septosporum following natural inoculation at Torrs Warren, Galloway 2013-2015

Data collected from a progeny-provenance trial to examine Dothistroma needle blight (DNB) infection in native Scottish populations of Scots pine.

Data include multiple infection assessments and height measurements and a single chlorophyll fluorescence measurement, record of branching and a defoliation assessment for each tree in the trial plus measurements of individual infected needles (length of lesions, number of lesions per needle, length of needle).

The trial was transplanted from CEH Edinburgh in April 2013 to Torrs Warren forest, Galloway, a site known to be infected with Dothistroma needle blight (DNB), caused by Dothistroma septosporum. The experiment ran until September 2015 with infection assessments (% estimated DNB severity per tree) performed roughly every 6 months from September 2013.

Provenance & quality

There are eight Scottish Scots pine populations (Ballochbuie, Blackwood of Rannoch, Beinn Eighe, Coille Coire Chuilc, Glen Affric, Glen Loy, Glen Tanar, Rothiemurcus) with four families per population each consisting of six individuals = total 192 trees. The trees were grown from seed collected at each site, and germinated in spring 2007 at CEH Edinburgh. They were transplanted in 2013 when they were six years old. The transplantation site at Torrs Warren was adjacent to stands of Corsican and lodgepole pine which were infected with Dothistroma needle blight.

The trees were transplanted in 6 litre pots and were staked to the ground at 0.5 m spacing. A guard row of Scots pine trees (also at 0.5 m spacing) was placed around the edge of the trial to minimise edge effects.

Weeding, to cut back brambles and bracken surrounding the trees, was performed annually in the summer.

The trial consists of six randomised blocks each containing one individual per family.

The data were collected as part of the PROTREE project (funded jointly by a grant from BBSRC, Defra, ESRC, the Forestry Commission, NERC and the Scottish Government, under the Tree Health and Plant Biosecurity Initiative) and Annika Perry's PhD studentship which was funded by NERC Centre for Ecology and Hydrology and Forest Research.
