Atlas de la flore patrimoniale du Val d’Oise

For over ten years, the Conservatoire Botanique National du Bassin Parisien (CBNBP) and the County Council of Val d’Oise have worked together to develop knowledge about the flora of the region of Val d’Oise, northern France, and together have produced the first synthesis of this heritage, which is both rich and threatened. Nearly 215,000 bibliographic and field data points, spread over nearly four centuries, have been inspected to bring the species count of wild flora in the department to a total of 1,321 species, summing over all periods. Of these, 209 species have not been seen since 2000 and can be considered extinct, while another 150 are more or less threatened in the short term.

Although it was made with great scientific rigor, the book is not reserved exclusively for experienced botanists, but is also aimed at environmental stakeholders such as local authorities or the general public wishing to familiarize themselves with the recognition and preservation of this valuable floristic heritage.
