## Summary

Natural England, a public authority in central government, initiated a tender process on 6th August 2025, focusing on "Surveillance of environmental exposure and assessment of effects from pesticides to bat species in England." This procurement falls under the research and development services category and involves assessing high impact pesticides on native bat species. The tender aimed to attract bids by 12th September 2025, with the project period starting on 26th September 2025 and concluding on 13th March 2026. The procurement utilized an open method, specifically "below threshold - open competition," and was located in the United Kingdom. A contract was awarded on 6th October 2025, with a total value of £25,000, including VAT, to ENVIRESEARCH LIMITED, which is based in Frodsham, UK. The main procurement stage was the award, which is now complete as of 16th October 2025.

This tender provides significant opportunities for businesses specialised in environmental research, particularly those focusing on ecological conservation and the effects of chemicals on wildlife. Companies with expertise in assessing the impact of pesticides, capable of providing novel national research of international standing, will find this contract aligned with their growth objectives. Small and medium enterprises (SMEs) would have been especially well-suited for this tender, given its focus on critical environmental research and the specific need for innovative methodologies in determining the toxicological thresholds of pesticide residues. The project's findings contribute to national and international literature and policy by informing DEFRA's indicator species assessments, presenting a robust platform for businesses aiming to establish themselves in global environmental research sectors.

## Notice

Quantification of the exposure and effects of high impact pesticides in native bat species is required to allow conservation of protected species and represents essential novel national research of international standing. Presence of pesticides in bat species, including from within the UK and England have been identified. However, the impacts of their toxicity have not been assessed. These facts are compounded by the fact that native bats are K-strategist species, are relatively long lived, have a high metabolic rate and therefore high nutritional intake requirements and undergo hibernation, all contributing to high risk from exposure to pesticides. Insectivorous bats consume agricultural pests in large numbers and so have a high exposure rate to pesticides whilst fulfilling a value ecological service and benefit to agriculture. All these factors make bat species suitable as indicators of pesticide exposure and effects. Pesticides will likely have an additive, synergistic or possibly antagonistic toxic effect upon exposed wildlife. It is essential to consider the toxic load of all relevant active substances together to determine risk to protected bat species. Direct effects from exposure to pesticides in bats can be accessed via analysis of residues in bat carcasses and subsequent risk assessment. It is proposed that up to 50 bats are analysed annually for high-risk pesticides. To elucidate effects of detected pesticides residues research will be required to allow determination of suitable toxicological thresholds for use to interrogate the exposure data. Only limited data exists in this area, comparison and adjustments will be required after considering all suitable international data available, including those from toxicological studies in other species such as mice. The pesticide residue results from bat specimens will be reported with associated developed novel effect assessment methodology analysis to present a likely risk to these protected species. As this work will be of both national and international importance there is also the opportunity to present the data and outcomes via a paper published in international science literature. This work is designed to feed directly into the effects of chemicals on D4/D5 indicator species conducted by DEFRA Pressures.
