As Senior Reserves Manager for Mendip, I lead a team that looks after over twenty Somerset nature reserves, including Bubwith Acres, Cheddar Wood and Ubley Warren, supporting wildlife conservation in Somerset.
Why nature reserves need active management
Our native wildlife evolved over thousands of years in a mosaic of grassland, scrub, and woodland. Before modern farming, that landscape was shaped by large herbivores - animals like aurochs and woolly rhinoceros - grazing, trampling and breaking up vegetation. Later, traditional human practices such as coppicing and small-scale grazing continued many of those processes.
This all changed in the 20th century. Agricultural intensification and the loss of traditional practices led to the disappearance of 97% of the UK’s species-rich grassland and a decline in woodland quality and connectivity.
Our Somerset nature reserves on Mendip represent the last remaining fragments of nature-rich land which escaped this fate – typically because they were too steep, rocky, and generally difficult to work on to have been considered worth converting to intensive farmland. To maintain them, we carry out active management that mimics the historical processes that once shaped the landscape. By rotationally clearing scrub from species-rich grassland, for example, we act as proxies for the grazing animals and traditional communities that would previously have kept these areas open. Without this work, we would gradually lose these remaining fragments and the species they support.
This is very different from simply “re-wilding” a site. While allowing some habitats to scrub up can benefit wildlife, it is generally not possible to recover high-quality species-rich grassland once it has been agriculturally improved, nor to recreate ancient woodland except over very long timescales. It is far more effective to prevent degradation than to try to reverse it later. Grasslands in particular can change dramatically in just a few years if management stops.
For these reasons, the work we carry out each year is essential - not only to prevent further loss, but to increase the resilience of these habitats to pressures such as climate change, pollution, public access and fragmentation. Our efforts in wildlife conservation in Somerset help secure these habitats for future generations.
