BeeWalkers walk the same fixed route (a transect) at least once a month between March and
October (inclusive). This covers the full flight period of the bumblebees, including emergence from overwintering and workers tailing off. BeeWalkers record the abundance of each bumblebee
species seen in a 4m x 4m x 2m ‘recording box’ in order to standardise between habitats and observers.
After three years and six in operation as a public recording scheme, the BeeWalk dataset now stands at 65,287 validated records of 24 bumblebee species.
