Abstract
This Fellowship will help resolve ongoing conflicts between two national priorities: the need for new infrastructure, and the safeguarding of protected species and their habitats. Improving national infrastructure is one of the 5 key pillars of the UK's Industrial Strategy. Alongside major enhancements to the transport networks and energy security, the National Infrastructure Delivery Plan includes the large-scale supply of housing, with the ambition to build 300,000 new homes per year. Yet the sustainable management of natural resources, including biodiversity, is also fundamental to the UK's long-term economic and social well-being. Ensuring the ecological sustainability of projected growth in the built environment is, for this reason, a pressing challenge. NERC science can help to meet this challenge only if it is readily accessible, in suitable formats, and accompanied by two-way dialogue between users and researchers. This Fellowship will help practitioners and decision makers to understand and mitigate more effectively for the impacts of major infrastructure developments on protected wildlife and habitats. It will therefore allow the Statutory Nature Conservation Bodies (SNCBs), as well as other stakeholders, to achieve their stated objectives of more strategic environmental protection and more robust and transparent decision-making.
I will build on a highly successful track record of end-user engagement to summarise and communicate evidence on the ecological impacts of major infrastructure (e.g. Mathews et al. 2015; Fensome et al. 2016; Lintott et al. 2016). Working with partners including the Chartered Institute of Ecology and Environmental Management and the SNCBs, I will develop new Good Practice Guidelines. Evidence gaps will be co-identified and prioritised with stakeholders, and strategies will be developed to address them. Approaches will include the tailored analysis of existing data, the development of collaborative grant applications for new research, and the improvement of monitoring strategies used by industry. For example, one of my PhD students is about to go on secondment to Natural England's Reform Team, exploring how new modelling approaches can be used to minimise the impacts of built developments on greater horseshoe bats. This involves transposing research models built for this species to a new, larger, geographical area. In this Fellowship, I will assess and pilot the feasibility of extending the approach to other species. I will also explore how the modelling approach could be aligned with stakeholder's existing computing and modelling capabilities, enabling its future use 'in house' without continual dependency on academic partner input. Responding to users' needs, and aligning with Defra's strategic aim (https://www.gov.uk/government/publications/defragroup- areas-of-research-interest) to "make more effective use of observations, data and processes to better understand risk, uncertainties and complexities in decision making", I will also support the development of rigorous ecological monitoring and mitigation schemes. Whilst ecological field surveys at development sites frequently utilise techniques developed by research scientists, limited understanding of statistical principles and of alternative techniques (e.g. theoretical modelling, population genetics) means that many schemes are currently open to legal challenge for being either disproportionate in terms of cost and time, or for failing to provide the required evidence. Improved monitoring strategies will also help to fill the evidence gaps identified in this Fellowship.

Description | Need for new clear guidance on ecological impacts of alternative lighting strategies for planners and ecologists established. The value of a new tool for monitoring bat movement through the landscape has been explored (see publications) and I am currently working on making this facility available online Creation of new Ecobat tool to enable better interpretation of bat activity data including likely proximity to roosts New Ecobat tool using roost-count rather than acoustic data has been set up in response to a need identified by collaborators on new Bat Mitigation guidelines, and will be recommended for routine use by the guidelines. Badger Mitigation and Dormouse Conservation Handbooks have completed their final rounds of reviews by the statutory authorities, and will be published in 2022. I have also led the writing of an evidence review on the conservation status of mammals in Wales for the Welsh Government |

Title | Dataset for paper: Passing rail traffic reduces bat activity |
Description | Data and analysis code for paper entitled 'Passing rail traffic reduces bat activity', appearing in Scientific Reports (2021). The raw data consists of 38 nights of acoustic, ultrasonic and video recordings made between 15th July - 20th September 2019, at 12 rail-side sites in South-eastern England (see Supplementary Materials Table 1 on article web page for details). Each night's recordings are contained within a separate zip archive, named by site number, followed by site name, day of recording at that site, and date (e.g. 2. Hassocks - Day 1 - 15.07.19.zip). Zip files are best opened with 7zip (Windows) or The Unarchiver (MacOS). The folder structure within each night's raw data zip archive is: |-- Bat Detectors ....|-- Detector 1 - XXX ........|-- Acoustic ........|-- Ultrasonic ....|-- Detector 2 - XXX ........|-- Acoustic ........|-- Ultrasonic ....|-- Video Camera XXX represents the detector's individual ID. Acoustic folders contain calibrated acoustic recordings of passing trains (wav format), and if the acoustic data was used in sound pressure level (SPL) calculations, SPL data (Praat v6.1.09 pkf format, also converted to a text file with file extension .Collection for importing into R (see below). Ultrasonic folders contain ultrasonic audio files (wav format) as labelled using Wildlife Acoustics Kaleidoscope Pro v3.1.5, along with Kaleidoscope metadata (csv format), a log (txt format) of files processed, and the settings file (ini format) used by Kaleidoscope. Files identified as noise are stored in a 'NOISE' subfolder. While the individual audio files and Kaleidoscope generated csv files can be opened using standard software, both are best viewed/played using Kaleidoscope v3.1 or higher. Intermediate processed data which were imported into R (see below), can be found in the zip archive Intermediate Processed Data (R Imports).zip, which has the following folder structure: |-- Bat Detectors ....|-- Acoustic ....|-- Ultrasonic ........|-- Discarded ........|-- Selected |-- Train Dimensions |-- Video Data |-- Weather Data The Acoustic folder contains data calibrating times between acoustic and video datasets (csv and xlsx format). Within the Ultrasonic folder, Kaleidoscope metadata files (with additional columns noting feeding buzzes and start/end times, csv format) are separated into Selected and Discarded subfolders depending on whether data from a given detector was used in the analysis (see Methods). The Train Dimensions folder contains the information used to determine average carriage length, and so estimate train speed (xlsx format), the Video Data folder contains timings of train passes manually extracted from the video recordings (csv format), and the Weather Data folder contains Gatwick Airport weather station records (csv format). Detector distance to trains, and site locations /timings (csv format) are provided at the top level of the archive. All R code (R version 3.6.2) used in further data processing steps, and the final analyses, plus the generated data (as csv files) are provided in a single R Project within the zip archive Data Processing and Analysis.zip. The R project contains a renv database containing all software packages and versions used, allowing the analytical environment to be reproduced using the R command renv::restore(). All paths to external files (outside the project directory) within the R code have been truncated to '/path/to/' before the file name. Consequently, paths to external files should be respecified (e.g. by using a search function to locate the file within the archives) before running affected code. Abstract: Rail transport is expanding, with a global increase in infrastructure of up to one-third predicted by 2050. Greater reliance on rail is expected to benefit the environment at a planetary level, by mitigating transport-related carbon emissions. However, smaller-scale, more direct consequences for wildlife are unclear, as unlike roads, railway impacts on animal ecology are rarely studied. As a group, bats frequently interact with transport networks due to their broad distribution and landscape-scale movements. Additionally, their nocturnality, and use of echolocation mean bats are likely to be affected by light and noise emitted by trains. To investigate whether passing trains affect bat activity levels, we monitored the two most abundant UK species using ultrasonic detectors at 12 wooded rail-side sites in southern England. Activity fell by = 30-50% each time a train passed, for at least two minutes. Consequently, activity was reduced for no less than one-fifth of the time at sites with median rail traffic, and two-thirds or more of the time at the busiest site. Such activity changes imply repeated evasive action and/or exclusion from otherwise favourable environments, with potential for corresponding opportunity or energetic costs. Hence, disturbance by passing trains may disadvantage bats in most rail-side habitats. |
