The National Biodiversity Data Centre have developed an eCourse for the Garden Butterfly Monitoring Scheme. The Garden Butterfly Monitoring Scheme provides recorders with an opportunity to record butterflies in their gardens. Ireland has 32 resident and 3 common migrant butterfly species and while this is quite a manageable number to learn, the National Biodiversity Data Centre only cover the 20 most common butterfly species in the Garden Butterfly Monitoring Scheme. This makes this recording scheme very accessible to beginners.
