Abstract
By the mean of a grid pattern using 20 x 20 km squares, 325 crop weed taxas from french region Nord-Pas-de-Calais have been mapped. The stud y first presents weed species that have disappeared from crop fields, or being so. The work proposes a distribution map classification accor ding to the frequencies within the squares, combined to geographical a ffinities. These appear especially linked with edaphical requirement s imilarities.
