Marginal Gains

Episode 5 takes us on top of the South Downs at the Wiston Estate where I join awesome entomologist, Graeme Lyons, on some invertebrate surveys. We’re looking at the benefits of having wildflower strips along the arable fields, and how having a diversity of these conservation options on the farm are providing habitat for nature alongside food production.

We talk about how the complex structure in the conservation headlands, wild bird seed mixes, fallow fields and nectar & pollen mixes offers opportunities for all sorts of beetles, bugs, spiders, bees, butterflies and moths, and in turn how these go on to provide food for farmland birds rearing their young.

Join us as we celebrate the tiniest of wildlife that Graeme has spent his life studying and sharing his passion for. As we sweep-net through wildflower margins and suction sample around beetle banks, Graeme explains how the conservation options that have been put in place at Wiston – from flower-rich strips and tussocky edges to unploughed corners – are helping create vital habitats. Farmland covers huge swathes of our landscape so we need to consider how nature can thrive in these areas too.
