The big butterfly count is a nationwide survey aimed at helping assess the health of our environment.
The survey is being launched during 2010 to mark the International Year of Biodiversity. 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 identify trends in species that will help plan how to protect butterflies from extinction as well as understand the effect of climate change on wildlife.
