Phytophthora ramorum, or P. ramorum, has presented unprecedented challenges to the:

  • forestry sector
  • land-use sector including agriculture

The impact on larch has been particularly significant. But, it also affects other host species such as Rhododendron and Vaccinium.

You can access the latest:

  • information
  • guidance, and
  • action plan for stakeholders

in our Phytophthora ramorum: management strategy. The aim of the strategy is to manage the spread of the disease. This will minimise the social, environmental and economic impact on our landscapes.
