All malignant invasive plant species originated from America (including Brazil, Mex-
ico, South America, Tropical America, Central America, and North America). Five of the
seriously invasive plants originated from America and seven from Africa, Europe, and
Asia. Three of the local invasive plants originated from America and two from Africa and
Asia. Two of the generally invasive plants originated from America and eight from Africa,
Europe, and Asia. Three species requiring further investigations originated from America
and four from Africa, Europe, and Asia (Table 2).
3.2. Distribution of Invasive Plants
Regarding the malignant invasive species, Bidens pilosa covered most regions of
Guizhou Province (Figure 2a), whereas Ageratina adenophora was mainly found in the south-
western part (Figure 2b). Praxelis clematidea was mainly reported from the southern part
(Figure 2c) and Erigeron sumatrensis from the eastern part (Figure 2d). Chromolaena odorata
had its main distribution range in the southeastern part (Figure 2e). Alternanthera philoxeroides
was mainly found in the central and eastern parts (Figure 2f), whereas Ageratum conyzoides
was mostly located in the central and southern parts (Figure 2g) and Ipomoea purpurea (L.)
Roth in the southwest part (Figure 2h). Occasional species, such as Dysphania ambrosioides,
Ambrosia artemisiifolia, Solidago canadensis, Parthenium hysterophorus L., Amaranthus spinosus L.,
and Ipomoea cairica (L.) Sweet were found in different regions (Figure 2i).View entire presentation
