  1. 1. Phytophthora ramorum Update Ben Jones Plant Health Operations Manager FC England
  2. 2. 2012 Survey Summary • 170 flying hours covering around 24,000 miles • 79,058 Ha of larch surveyed across England, Wales, Scotland, N Ireland & IOM (increase in around 10,000 Ha compared to 2011) • Equates 70% of all larch that has been analysed across the UK both on respective PFEs and in PW • In England this resulted in increased investigations of 597 sites (compared to 455 in 2011) which in turn lead to the issuing of 163 Statutory Notices (compared to 120 in 2011)
  3. 3. 2012 Survey Summary • Observation of disease dynamics continue to be different in different parts of the country – the more larch, the bigger the problem • Significant new findings in SW Scotland, significant increase in S Wales, limited new findings in the Forest of Dean and SE England • Weather conditions have been extremely conducive for Pr throughout 2012 – likely to see further infection • Further findings generally being made in association with known infected sites (both rhodo & larch), but rapid advance of symptoms in some locations were observed over the summer

  17. 17. Phytophthora ramorum symptom progression on infected larch stands in the UK • Cold spring delayed start of aerial surveillance by nearly 4 weeks • Flights started in England and Wales in the 10th May, 4 flights undertaken so far, 2 in Wales and 2 in England. • FC Scotland undertaking their own surveillance this year, flight started 22nd May • Flights undertaken to the Lake District and Wales last week, and along the South Coast and to E Anglia this week 2013 Surveillance

  25. 25. 2013 So Far………. • Observations in general haven’t been good…highlighting further the pattern of the more larch, the bigger the problem once infection becomes established • Significant but manageable findings in the SW, but the scale of infection in S Wales will lead to unprecedented logistical challenges with the potential for collateral damage to other species both in and out of the forest / woodland environment • Observations continue to highlight that early detection and prompt action is still the most effective way of managing the disease across hosts species including rhododendron
