Butterfly Recording

Butterflies Butterfly Recording Butterfly List

Overview

Butterfly recording by transect is carried out between April and September annually. Each week, subject to weather conditions, the same route is walked, and all butterflies seen within an imaginary five-metre box along that route are recorded. At the close of the season the records are sent off to be added to those from around the country. By this means the rise and fall of species and numbers is monitored.

In addition, from time to time other areas on the reserve not included in the regular transect are visited, and butterfly species and numbers noted.

Records of butterfly numbers have been kept since 2000, and the following charts show the Maximum Annual Count for each species recorded on the Reserve to 2013, and also the Maximum Monthly Counts for the last four years.

Fluctuations in numbers of individual species on the Reserve, with variations from season to season.
