The new National Plant Monitoring Scheme (NPMS), launching in spring 2015, will for the first time enable scientists to take an annual stock take of the UK’s wild plants and their habitats, but to do this we need the public’s help. We are looking for volunteers to carry out surveys of wildflowers and their habitats that will provide robust evidence of which widespread plants are increasing or declining, as well as indicating the changing state of our most valued habitats such as grassland, fenland and even road verges. Plants are nature’s building blocks and this new monitoring scheme will sit alongside existing schemes for the UK’s birds and butterflies to help us understand more about how the countryside is changing.
