Strong of a century of engagement with more than 50 000 members , 5000 active volunteers , 400 employees on the national territory and a network of local associations active in 83 departments , the LPO is today the first association of protection of nature in France.   

It works on a daily basis for the protection of species, the preservation of spaces and for education and awareness of the environment.

It is the official partner in France of the BirdLife International network (120 representatives and nearly 2.8 million members worldwide).

The LPO was created in 1912 to put an end to the massacre of Atlantic Puffin in Brittany, a marine bird that has since become its symbol. It was recognized by public utility in 1986. It is directed by Yves Verilhac and chaired by Allain Bougrain Dubourg.
