Weed pteridophytes for the Socialist Republic of Vietnam

Abstract
The study of the flora for the Socialist Republic of Vietnam (SRV) has received sufficient attention over the past decades. Pteridophytes were cited as an inherent spore component for the vascular flora. Active conversion of landscapes containing intact forests has created suitable habitats for alien species by changing the structure of phytocenosis. The government of Vietnam is actively developing a legislative framework on the issues for combating alien “agents” on its territory. In 2008, the Biodiversity Law appeared, which became the first national legislative document, then circulars were developed in 2011, 2013 and 2018. Thereby it’s circulars Vietnam officially began to combat and control the spread of invasive species on its territory. For the goal of our research, we chose pteridophytes, at the moment, 1133 species from 170 genera and 38 families have been identified in Vietnam (including Lycopodiopsida). Many species are quite widespread not only in natural habitats, but are also present in cities, on arable lands and in urban communities. We noted 82 species from 38 genera and 17 families, among which 20 are exotic species, and 62 are native species that can grow/occupy biotopes and cenoses that are not typical for them in nature. Most fern-like plants were observed in the synanthropic group and in disturbed habitats. The process of introduction in countries with tropical and subtropical climates is poorly controlled, and spore plants, due to the insignificant mass of spores, can spread over fairly large distances. However, data on “weedy” fern species in Vietnam are still insufficient or contain incomplete information on the geographical distribution and population size of specific species compared to studies of aquatic invasive plant species in developed countries [18]. Domestic standards need to be brought into line with international ones, and the provision of scientific and standardized work for biodiversity and ecosystem services must be strengthened.
