From the Cairngorms to the South Downs, from Exmoor to Rannoch Moor, the NPMS is providing robust botanical data from across the UK to monitor change in 30 habitats at small-scales.  Well over a thousand volunteers have chosen one or more 1km2s to monitor long term. Up to 5 plots are chosen for each square and surveyed twice a year. There are 3 different survey levels allowing for a range of skills and confidence.
