## TL;DR

This paper assesses the risk of importing Hamamelis mollis plants from the UK into the EU for potential plant health threats.

## Contribution

The study identifies two EU-regulated pests associated with Hamamelis mollis plants from the UK.

## Key findings

- Phytophthora ramorum non-EU isolates and Scirtothrips dorsalis are considered relevant pests for this commodity.
- No non-regulated pests were identified as requiring further evaluation.
- The assessment is based on available scientific and technical information from the UK.

## Abstract

The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘High risk plants, plant products and other objects’. This Scientific Opinion covers plant health risks posed by rooted plants in pots of Hamamelis mollis imported from the United Kingdom (UK). The assessment was performed considering the available scientific information, including the technical information provided by the UK. All pests associated with the commodities were evaluated against specific criteria. Two EU regulated pests (Phytophthora ramorum non‐EU isolates and Scirtothrips dorsalis), present in the UK and potentially associated with the commodity, were considered as relevant for this Opinion. No pests non‐regulated in the EU were identified to be selected for further evaluation.
