Invasive and introduced species
Synanthropization in the Republic of Moldova is the extensive athropic activity challenged the invasion of anthropophyle (synanthropic) species in degraded agrarian and natural ecosystems and brakes the processes of natural development and restoration of natural bioceonosis. Prezenta plantelor invazive în ecosistemele naturale indica tendinta de sinantropizare a florei Republicii Moldova.
Synanthropic flora of 3 main groups: ruderal, segetal and adventitious. Their species diversity contains 463 species. Buruienile - plante cu caracter agresiv - alcatuiesc 114 specii.
Grupa speciilor de carantina (11 specii), afecteaza, mai cu seama, ecosistemele terestre naturale, de pajisti, degradate si agroecosistemele. Un pericol considerabil pentru ecosistemele forestiere reprezinta artarul american (Acer negundo).
Colectiile institutiilor din Republica Moldova cuprind cca 14 mii specii de plante.

Flora of the republic's forests are characterizes by a weight of introduced species (38,7%) from other floristic regions. Some of them have a special importance for country's (white poplar, white acacia and others) occupying vast treeing places.
