The Natural Sciences and Agricultural Society of Agenais is an association created in 1973 originally by agricultural technicians and advisors keen to deepen their knowledge of plants and crops in the region. Today, it comprises around one hundred members and carries out several activities: - educational outings in the Lot-et-Garonne department, led by an expert botanist, to introduce the general public to the flora and fauna of the region - the management and maintenance of a 2-hectare botanical garden located in the municipalities of Pont du Casse and Bon Encontre, which aims to bring together plants native to Agenais and to work toward their preservation and knowledge - participation in events to promote the conservation of biodiversity
