  1. Cease grazing on grassland to allow early succession

    A before-and-after study in the 1920s in a grassland in England, UK (Henning 1987) reported that one year after sheep grazing was ceased, a large blue butterfly Maculina arion population was no longer recorded. Results were not tested for statistical significance. Before fencing was erected to stop sheep from grazing, there was a population of large blue butterflies, but later in the year after fencing was erected numbers of adults had declined and one year later no butterflies were recorded (no data provided). Fencing was erected around an area of grassland which contained a population of large blue butterflies to exclude sheep and other intruders. Surveys were conducted in the two flight seasons after fencing. Further survey details are not provided.
