Monitoring & Research

At any one time, we may have particular focus to the projects taking place, which you may be interested in contributing too. This year, we have a special interest in invertebrates. If you visit the Great Fen for personal interest, feel free to submit your own wildlife sightings of insects or other wildlife to Henry Stanier.

If you would like to get and idea of what to look out for, as well as checking for postings on social media, you can browse our sightings reports. 

Our ongoing investigation into the movements of our stonechats at the Great Fen continues. If you would like to find out more, read about our stonechat research and look out for updates on this topic and others in our monitoring & research blogs.

Since the 1800’s wildlife has been recorded at Holme Fen and Woodwalton Fen. What started out as wildlife recording has developed into more structured programme of survey and monitoring. To understand the benefits of the restoration work at the Great Fen we need to gather data before, during and after.

We gather information about the farmland, the land being restored and the existing nature reserves in this diverse Living Landscape, and on the movement of wildlife within it and, in and out of the Great Fen area. The information gathered on groups of species and their habitats then shapes the future management of the landscape.

The annual programme of monitoring and research on the Great Fen is coordinated by the Monitoring and Research Officer, Henry Stanier, This programme helps to determine the effectiveness of restoration and the development of habitats and colonisation of species. This involves working alongside project partners, academic institutions and other landscape scale restoration projects.

Such work is carried out by a team of dedicated volunteers, the Great Fen Monitors as well as Wildlife Trust staff, Natural England staff, contractors, local natural history societies, university students and visiting naturalists.

A wide range of wildlife is monitored as part of the programme including birds, mammals, invertebrates, amphibians and plants. The abiotic data is also recorded, such as temperature, rainfall, water levels, water quality and carbon emissions. This enables us to look at any correlation of species movement and population with changing environmental conditions and feeds into national schemes measuring climate change
