Timed and GPS Counts
Different techniques are required to monitor the populations of some of our rarer butterflies. For example timed counts where a single species is counted over a given time with no fixed route (unlike the Transect). This can apply to adult butterflies, larvae or eggs.
Another method is to use a GPS to mark the position of each target. This can then be downloaded onto an OS map to show where the butterfly is breeding. This can be accompanied with habitat photographs and can become a very useful management tool.
