Aim: To compose a comprehensive research report of alien plants that characterizes the taxonomic work of the last 20 years in Beijing-Tianjin-Hebei.

Methods: A total of 46 families, composed of 141 genera and 210 species, that were previously reported as alien invasive plants were characterized on the basis of available literature reports, taxonomic studies, and field surveys in Beijing-Tianjin-Hebei. The primary considerations for the classification of invasive species were: (1) the number of specimens collected, (2) the time point of collection, (3) the amount of relevant literature reports, and (4) the level of national invasion determined through field investigation.

Results: Based on taxonomic classification of the available data, 57 and 153 species were broadly categorized as native and alien, respectively. Of those considered as alien plant species, 82 species were determined to be invasive in Beijing-Tianjin-Hebei.

Conclusions: Overall, the taxonomic work of the last 20 years in Beijing-Tianjin-Hebei has demonstrated an inaccurate representation of its resident alien invasive plant populations. This is particularly due to the lack of relevant research and basic knowledge. Therefore, it is necessary to launch a more comprehensive investigation on these plant populations to identify alien invasive plants more easily and to implement effective management strategies for Beijing-Tianjin-Hebei.
