The Big Butterfly Count
This is a nationwide survey aimed at helping us assess the health of our environment. It was launched in 2010 and has rapidly become the world's biggest survey of butterflies. The 2020 Big Butterfly Count saw the highest number of butterfly sightings ever submitted by the general public with 111,628 participants submitting a record-breaking 145,249 counts this year, an increase of 25% on 2019.
Butterflies react very quickly to change in their environment which makes them excellent biodiversity indicators. Butterfly declines are an early warning for other wildlife losses. The count also assists us in identifying trends in species that will help us plan how to protect butterflies from extinction, as well as understand the effect of climate change on wildlife.
The count takes only 15 minutes to do and you do not need to be an expert. If you are unsure about identifying butterflies, you can download a free identification chart.
Records from all types of places add to the picture. And even if you record nothing, that adds to our understanding of species distribution and trends, so “nil returns” are as useful to us as a long list would be.
Please remember to send in your sightings, this can be done via your phone or on the website:
