The Plant Health Alliance (owner of the freely-available Plant Health Management Standard and the Governing Body of the Plant Healthy Certification Scheme) released their 5-year plan to coincide with the Plant biosecurity strategy for Great Britain (2023 to 2028) launch.

Restrictions on the felling and movement of timber from demarcated areas in Scotland affected by the tree disease Phytophthora pluvialis will be lifted as of 24th January 2023.

This move follows research which showed that the risk of the disease spreading via timber material is low.

The new Great Britain-wide strategy sets out five-year vision for plant health and biosecurity. Actions include increased e-commerce monitoring and strengthening outbreak response capabilities

A small number of Ips cembrae bark beetles have been intercepted in the west of Scotland conifer bark beetle Pest Free Area. Ground surveys have not detected any breeding populations, but a temporary cessation of movement of larch to Northern Ireland and the Republic of Ireland has been put in place until further surveillance is completed.

Scottish Forestry’s "Phytophthora ramorum on larch Action Plan" has recently been reviewed. The current policy approach will continue, and the risk zones (Priority Action Zone and Risk Reduction Zone) established in June 2021 will remain in place, with no changes to the boundaries. The Action Plan will next be reviewed in July 2023.

The Tree Council has published a concise guide to ash dieback for homeowners or landowners in Scotland. The Guide for Tree Owners in Scotland provides helpful information for anyone responsible for managing ash trees and highlights specific policy and resources relevant to Scotland.

Two new Demarcated Areas for Phytophthora pluvialis came into force at midday on the 19th of July 2022. These are Area No. 2 in Highland and Area No. 3 in Argyll and Bute. Demarcated Area Notice No. 2 revokes and replaces Demarcated Area Notice No. 1 which was issued on 8 December 2021.

Pine Processionary Moth (Thaumetopoea pityocampa) on Pinus sylvestris and Pinus nigra trees imported from a French nursery were intercepted at a nursery in England. Statutory plant health notices have been issued to the affected nurseries and the destruction of all infested Pinus trees has been completed.

Fera have reported that testing of S. sisymbriifolium seed found Potato spindle tuber viroid (PSTVd) in several samples, which indicates that sticky nightshade is a natural host of PSTVd. They conclude that "Given the increased interest in the use of S. sisymbriifolium as a trap crop for PCN management in potato rotations, the role of this crop as a host of PSTVd and the risk of seed transmission and transmission via roots should be further investigated".

Scottish Forestry have confirmed a second finding of Phytophthora pluvialis in Scotland, a tree disease that is capable of affecting several tree species, including western hemlock, Douglas fir, tanoak and several pine species (particularly radiata pine).
The second location is at a woodland site near to Loch Awe in Argyll, and was picked up by ongoing surveillance.
