Some farmers grow only one type of crop in very large fields.
Why does replanting hedgerows and field margins around these fields increase biodiversity?
They increase the yield of the crop, so more food is available for animals
They provide a variety of habitats and food sources for many different species
They stop pests from reaching the crop, so fewer pesticides need to be used
They increase the number of individual crop plants growing in each field
