Field Study Permissions

The following information was supplied relating to field study approvals (i.e., approving body and any reference numbers):

The site assessment, which was carried out by AECOM ecologists, was approved by Liverpool City Council (project number: 60554511), via an acceptance of a scope and quote letter and an agreement of Terms and Conditions. AECOM is a multidisciplinary consultancy, the site assessment was primarily to determine any ecological constraints relating to restoration and re-development of the site. The described case study was integrated into this site assessment. Given the socioeconomic impacts of Japanese knotweed presence in the UK, the location and client will be kept confidential.

Data Deposition

The following information was supplied regarding data availability:

Two supplemental data files are provided in Excel format. 'Fennelletal_supplimentalinformation_1' provides the contractor and surveyor responses to the various survey questions. 'Fennelletal_supplimentalinformation_2' provided the raw data from the case suture assessment.

The raw data are provided in the Supplemental Files.
