Article 19A of the order states:
"Notification of the landing of certain plants for planting. A person who brings the following plants into England must notify an inspector in writing...no later than four days after the date of their arrival in England."
"They are plants of Castanea Mill., Fraxinus L., Pinus L., Platanus L., Prunus L., Quercus L. or Ulmus L., intended for planting, which have been grown or are suspected to have been grown in another member State; or plants of Castanea Mill., Fraxinus L., Pinus L., Platanus L., Prunus L., Quercus L. or Ulmus L., intended for planting, which have been grown or are suspected to have been grown in Switzerland and to which the requirements of article 6 do not apply.
"The matters are the intended date of their arrival or, if they have arrived in England, the date on which they first arrived in England; their intended destination, or if they have arrived at their intended destination in England, their current location, their genus and species; the identification number of the supplier of the plants; and the country from which they have been, or are to be, consigned."
An APHA spokesperson said: "Following a consultation in 2015, Prunus has been added to the UK statutory notification scheme, to take effect from 24 February. This means that we are better able to protect the UK against the risks from a number of harmful organisms whose main hosts include Prunus species. Many of these organisms are present elsewhere in the EU, but not in the UK. They include Xylella fastidiosa, Anoplophora chinensis and Xanthonomas arboricola pv. pruni, as well as unlisted pests such as Platynota stultana and Aromia bungii."
"The statutory notification scheme already in place applied to oak, plane, sweet chestnut, pine, elm and ash trees. The scheme was put in place to help the Plant Health and Seeds Inspectorate (PHSI) and their equivalents in the Devolved Administrations build intelligence about particular trades, particularly those where there is a risk of introducing harmful organisms, and to help target inspections of such trees. The information gathered is also valuable in the event of an outbreak, enabling the PHSI to more easily trace the movement of potentially infected stock."
