Common biodiversity is a good indicator of a territory’s health. In March 2006, the French National History Museum launched, together with several organisations, the Garden Butterfly Observatory (l’Observatoire des papillons des jardins) for which it has called on all French people with a garden: with the help of a butterfly identification guide available on the Internet and count sheets, everyone can take part in this large scale observation of common biodiversity. Since 2007, the Garden Butterfly Observatory has mobilised 1 850 new volunteer observers. In total, there are there 5 889 gardens observed regularly and over 17 000 internet users informed each month through the « Papillons & Jardin » (« Butterflies & Garden ») newsletter.
