The big butterfly count 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.
Why count butterflies?
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.
That’s why counting butterflies can be described as taking the pulse of nature.
The count will also assist 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.
