Comparison Plant communities Paris 1884-2021

The data presents the changes that occurred in Paris plant communities at a 136-year interval, thanks to the existence of an inventory published in 1884 in a book entitled “Essay on the flora of the Paris pavement limited to outer boulevards, or Catalog of plants that grow spontaneously in streets and on wharves” (Vallot 1884), by a well-known French botanist Joseph Vallot. In 2021, we followed on his footsteps, using the same inventory protocol at exactly the same places : 35 streets, 15 quays and 2 squares in Paris (France). We focused on the spontaneous flora and excluded cultivated/ornamental vegetation. The habitats sampled all belonged to the micro-structures that support vegetation i.e., cracks in asphalt, the base of alignment trees, the feet of walls, the spaces between paving stones… The data gives the list of the species, their ecological characteristics, and the name of the places where the inventories were performed.
