Converting a site into wildflower grassland can significantly increase its biodiversity. This note provides practical advice on how previously cultivated land can be made more species rich in this way.
There is advice on sources of wildflower seed, along with recommendations on the ideal seed mixtures for different situations. There is also guidance on establishing grassland – including seed-bed preparation and controlling undesirable species – and subsequent long-term management.
The common problems of creating wildflower grassland are discussed, such as the residual fertility of ex-arable soil. High nutrient levels favour the rapid growth of competitive species, leaving no room for the slower growing typical grassland species. Therefore, there is advice on how to reduce soil fertility and manage grassland on fertile soils.
