Opinion of the Scientific Panel on Plant Health on the pest risk analysis made by EPPO on Hydrocotyle ranunculoides L. f. (floating pennywort)
Following a request from the European Commission, the EFSA Scientific Panel on Plant Heath was asked to deliver a scientific opinion on two pest risk analyses made by the European and Mediterranean Plant Protection Organization (EPPO) on invasive alien plants (American skunk cabbage and floating pennywort). The Panel was in particular asked a) whether these organisms can be considered as harmful for the endangered area of the European Community and thus potentially eligible for addition to the list of harmful organisms in the plant health Directive 2000/29/EC, and b) whether the identified management options are appropriate through an evaluation of their efficacy, feasibility and impact.
This document presents the opinion of the Panel on Plant Health on the pest risk analysis made by EPPO on Hydrocotyle ranunculoides L. f
H. ranunculoides is a stoloniferous, perennial, aquatic plant, known as floating pennywort. It is native to North America, where it is considered endangered in some areas, but has been introduced and subsequently naturalised in water bodies within a number of European countries, including Belgium, Denmark, France, Germany, Italy, the Netherlands, Portugal, Spain, and United Kingdom (UK). It is reported as invasive in Belgium, the Netherlands and the UK, forming dense mats of vegetation in still and slow-flowing water courses. An important pathway of entry and spread is the intentional introduction of H. ranunculoides through the trade in aquatic plants.
