About this contract

NE are looking to commission an evidence review on the risk from navigational dredging and disposal activities as a pathway of introduction for Non-Native Species (NNS). We have limited information on the mechanisms by which this activity could spread NNS, with a particular concern to invasive species. We are keen to understand the survival rates of species from dredging activity and through disposal, particularly for coastal /estuarine beneficial use and beneficial placement disposal sites as well as understand the subsequent (if any) risk to statutory protected sites and the wider seas. This information will help inform our advice to regulatory bodies as well as support development of a future guidance note to be developed by Statutory Nature Conservation Bodies on beneficial use of dredged material. Additional information: To apply for this opportunity you must submit your quotation meeting the requirements detailed in the Request for Quotation (RFQ) attached. Your response must be sent to Jan.Maclennan@naturalengland.org.uk by 17:00 on 22/09/2023. If you have any clarification questions linked to this opportunity please submit these via email to both Amanda.Yeomans@naturalengland.org.uk and Jan.Maclennan@naturalengland.org.uk (deadline for questions 14/09/2023).
