## Description
As part of the ReSCUE project, Natural England is seeking the services of a contractor to develop a R Shiny app wrapper for a set of tools and associated information developed during the project. This app will be deployed online and provide a user-friendly interface to ensure the outputs from the project are readily accessible and the impacts are maximised. This work fits under ReSCUE Work Package 3, which aims to develop a Seabird Flight Height Toolkit, providing functionality agreed with industry stakeholders and experts in an Expert Panel Workshop that was held in November 2025. The toolkit will be one of ReSCUE's flagship, public-facing outputs. We envisage offshore wind (OWF) developers, consultants, Statutory Nature Conservation Bodies (SNCB) colleagues, Environmental Non-Governmental Organisations (eNGOs), and academics using the toolkit as the default industry reference point for accessing seabird flight height distributions and data in the UK.
