Live data flows through dashboards and a dedicated mobile app, giving our teams instant insights into visitor patterns, facility usage, and potential operational needs.
Built on Microsoft Azure, the system integrates multiple data streams - from footfall counts to weather data - creating a comprehensive understanding of how visitors interact with the estate. This allows us to proactively manage visitor flow, optimise staffing levels, and maintain facility standards, all while preserving the authentic heritage experience that makes Blenheim unique.
The Smart VMS exemplifies our commitment to innovation in heritage management, demonstrating how modern technology can enhance both operational efficiency and visitor satisfaction while respecting the historic character of our estate. It's not just about collecting data - it's about using insights intelligently to protect and share Blenheim Palace for future generations.
This project, developed in partnership with Oxford Brookes University through a Knowledge Transfer Partnership, showcases how historic estates can embrace digital transformation while staying true to their core mission of heritage preservation.
Through the Smart Visitor Management System, we have established a powerful new capability at Blenheim Palace that enables data-driven decision making across our operations. While this marks a significant milestone in our digital transformation, it represents just the beginning of our journey as we continue to enhance and expand the system's capabilities to better serve our visitors, staff, and the historic estate.
"This KTP is an excellent example of what can be achieved when you bring together a forward-thinking organisation, in this case Blenheim, and the deep expertise and academic rigour from Oxford Brookes University. The Smart Visitor Management System the team have jointly developed is already helping Blenheim work more efficiently while enhancing the experience of visitors to the Palace."
Weaveley Solar
Biodiversity Monitoring at Weaveley Solar Farm
At Weaveley Solar Farm, we're demonstrating how renewable energy and nature conservation can work in harmony. This innovative project goes beyond traditional solar energy production to create a blueprint for sustainable land management and biodiversity enhancement.
After more than a century of intensive farming, we're giving the land an opportunity to regenerate through careful environmental stewardship. Our comprehensive biodiversity monitoring programme uses cutting-edge technology, including IoT sensors and bioacoustics, to measure and document the site's ecological recovery. This scientific approach helps us understand and share how solar farms can positively impact local ecosystems.
Our vision extends beyond energy generation. We're creating a model that shows how solar developments can contribute to both renewable energy goals and ecological restoration. The project demonstrates that with thoughtful planning and management, solar farms can enhance biodiversity, improve soil health, and support local ecosystems while producing clean energy.
The 30-year project aims to set new standards for responsible solar energy development, providing valuable insights for future renewable energy projects. By carefully documenting and sharing our findings, we're helping to shape the future of sustainable energy infrastructure that benefits both the environment and clean energy production.
Through the Weaveley project, we're proving that the choice between renewable energy and environmental preservation isn't an either/or decision - it's an opportunity to achieve both goals simultaneously, creating a legacy of sustainable development for future generations.
Collaborating with Oxford Brookes University we have revolutionised how we process and understand bioacoustic data. Initially focusing on bird and bat recordings, the team has developed efficient methods to analyse these complex soundscapes. Building on this success, we've created techniques to study the hidden acoustic world of soil life.
Soil ecoacoustics is an emerging field that explores the soundscape of the soil environment and its relationship to ecological processes. It focuses on understanding the acoustic signals generated by soil organisms, plants, and physical processes within the soil, and how these sounds can be used as indicators of soil health and ecosystem dynamics.
The team has created software that filters out non-biological sounds from soil recordings, revealing the subtle sounds of underground biological activity. This approach provides new insights into soil health and biodiversity that were previously difficult to obtain.
Currently, the team is expanding their capabilities by developing machine-learning models to identify and quantify grasshopper and cricket species through their acoustic signatures. This ongoing work represents another step forward in our ability to monitor and understand biodiversity across the estate, from the air to deep within the soil.
"Blenheim's Innovation Team have taken an impressively forward-thinking approach to biodiversity monitoring. The measurement of biodiversity is challenging and often controversial and the methods chosen should be appropriate for the habitat under study. Unravelling the effects of habitat change on biodiversity from those effects driven by seasonal variations often results in conclusions with a larger degree of uncertainty than is desired.In a pioneering step away from traditional and intensive survey methods the Innovation Team have set out to develop a biodiversity monitoring plan for Weaveley using a mix of both conventional surveys of indicator species alongside long-term abundance-over-time methods.
Blenheim have committed to the traditional long term survey of ground beetles as site indicator species. Such indicator species have a local and restricted range and are wholly or partially dependent on the site and it’s habitat for most or all of their lifecycle. It is often the case that studies are far too short term to derive any really meaningful conclusions, but data spanning the 25-year lifetime of the Weaveley project would be extremely valuable.
What's particularly exciting is their pioneering work with automated recording methods so that there is a more continuous set of ecological and physical data which although will not give in-depth point samples of species composition, should reflect changes caused directly or indirectly by site management or seasonality.
Such automated biodiversity methods give an estimate of abundance-over-time and some estimate of species diversity and have been developed by the Innovation Team by combining traditional ecological understanding with our growing world of accurate digital sensors and remote technology. For example the use of bioacoustics to monitor soil and plant ‘health’ , the activity patterns and species composition of grasshoppers and crickets, birds and hopefully bats. Simple time-lapse cameras provide human and machine-readable images recording changes in solitary bee occupation and allied parasites using bee hotels, or the variety of macro and some micro moths attracted to light.
The Innovation Team have sought to avoid collecting sparse and difficult to analyse data, but are seeking to revolutionise how we monitor and collect data to understand ecosystem ‘health’ within a large-scale solar project. This challenging programme stands out for its pioneering approach and, supported by Blenheim’s long term committent, should result in a step forward in automated biodiversity monitoring methods with the ultimate aim to promote biodiversity by driving change in management practices.”
Dr. Curt Lamberth
Our monitoring approach combines IoT sensors, camera systems, and bioacoustic monitoring to track species abundance and behaviour over time. Weather stations and soil sensors help us understand environmental conditions and isolate the effects of the solar installation from natural seasonal variations. We've deliberately chosen methods that focus on measuring long-term abundance rather than simple species diversity, enabling us to detect meaningful changes against background variation.
The programme includes:
- Environmental monitoring through weather stations and soil sensors
- Wildlife observation via smart bird and bat boxes
- Bioacoustic monitoring using Audio Moths for species identification
- Time-lapse photography for studying insect behaviour
- Bi-annual multispectral surveys of vegetation health
This innovative monitoring strategy demonstrates how renewable energy projects can contribute to both clean energy production and biodiversity enhancement, setting new standards for sustainable development.
Building on our established monitoring programme at Weaveley Solar Farm, we're expanding our impact through educational outreach and data-sharing initiatives. A key focus will be engaging with local schools to enhance STEM learning opportunities, where students can access our open data and learn to build their own environmental sensors using our developed code and methodologies.
We will be producing our first annual report, documenting the ecological changes we've observed and insights gained from our innovative monitoring approaches. This first report will share our findings on species abundance, soil health, and the relationship between our solar infrastructure and biodiversity.
