The requirement of the provider is to provide a rapid literature review. The purpose of the review is to bring together existing knowledge on how physical modifications, pollution, sediment, altered hydrological regimes, management (eg. aquatic plant management, fisheries management) invasive non-native species and climate change impact species abundances and extinction risk. The project should consider species associated with lakes and ponds, rivers, coastal and estuarine habitats. Through providing a review of existing qualitative and quantitative data, this work will contribute to developing our general understanding of the current evidence base around how pressures on aquatic habitats will affect our ability to deliver the environment act targets for species. The review should also identify gaps. ## CPV classification Research and development consultancy services Source Contracts Finder (UK) [View official notice](https://www.contractsfinder.service.gov.uk/notice/a1c191dc-cd58-4017-81ff-9b636a63aec6) Never miss a tender like this again Get AI summaries, deadline alerts and a bid pipeline for tenders matched to your business.
