| Abstract | ||||
| This study deals with species diversity of ruderal habitats in Nile Delta region. Over 400 stands, representing 18 habitats, were sampled in the study area. Of the 248 species encountered, few were common throughout all habitats. Annuals were more represented along the terraces of highway roads, solid refuse areas and trampled fields, while perennials were more represented along the slopes and depressions of old roads in railway yards. The diaspores of more than half of the recorded species are microschlerochores (light diaspores), ballochores (diaspores with explosion mechanisms) and pogonochores (diaspores with long hairs). For almost-all habitats, species diversity was higher in spring than in the other seasons, particularly summer and autumn. Communities of abandoned salinized fields, terraces and depressions of highway and railway roads had the highest species diversity, while those of trampled fields, trampled railway yards, terraces, slopes and depressions of old roads had the lowest. | ||||
