Methods

Standardized butterfly surveys were completed in the course of annual eight-week research seasons, running between June-August. All butterflies seen in a 5 minute walk along the length of a plot (50m x 10m) were counted. Butterfly counts took place between 10am and 4pm, to avoid the cooler parts of the day. Butterfly counts did not take place if it was raining, however, butterfly abundance still depends on weather/time of the day. The team aimed to repeat the survey of each site two or three times (dependant on suitable weather conditions) each survey year to reduce the impact of weather conditions on the data. Nearly all plots were surveyed two or three times. Weather caused seven sites to be surveyed just once.
