The impact of forest infrastructure reconstruction on expansion of potentially invasive plant species: First results from a study in Latvia

Today, when anthropogenic pressure on natural ecosystems promotes degradation of natural habitats and facilitates distribution of alien species, local disturbances such as forest management become more significant in relation to alien plant species expansion. The aim of this study was to investigate the impact of forest road and drainage network reconstruction on the vegetation composition focusing on the expansion of invasive alien plant species. The occurrence and coverage of vascular plant and bryophyte species were recorded within 160 sample plots along four forest roads and four drainage ditches. This paper summarises the first results of this study. The main results indicate that small-scale linear corridors like forest roads and drainage networks can promote the expansion of invasive alien plant species.

The Impact

The aggressiveness of invasive alien plant species has been amidst the changing climate, which has necessitated further research in this area. The impact of invasive alien plant species in the Panchase area of Nepal was assessed through the forest resource assessment and other methodologies such as, household survey, group discussion, direct field observation, participatory cluster mapping, quadrat sampling, laboratory analysis, and GIS mapping. A total of nine major invasive species, in which Ageratum houstonianum and Ageratina adenophora were found spread throughout the ecosystem. The invasion was fueled by anthropogenic disturbances such as leaving the agricultural lands, fallow and degradation of habitat. As a consequence, native species such as Artemisia indica and Urtica dioica were outcompeted mostly in the fringes of fallow lands, agricultural lands and in the disturbed sites. The intrusion was, however, less in the forest area, implying that community-managed dense canopy forests are less susceptible to invasion and routine management can offset the negative effects of invasion. Even though many negative consequences of the invasion were observed in the study sites, the possibility of the economically exploiting the biomass of invasive alien plant species for generating income locally was noticed.Banko Janakari, Vol. 27, No. 1, page: 31-42

And Control

Abstract 26 species of invasive alien plant species enter the arable land in Bulgaria as weeds. Some of these species are already causing economic damage and are included in the list of the 100 most economically important weeds. For others, it is only a matter of time before they are included in this list. Possessing a complex of qualities, they spread quickly and aggressively, occupying new areas and settling permanently in them. As artificial habitats in which there is no permanent vegetation, arable land is one of the easiest terrains to invade. The study examines the biological characteristics that determine the invasive nature of this group of plants, their origin, distribution routes, weed crops and control measures that can be taken. Particular attention shall be paid to the additional effects that these species may have on human health, on cultivated crops and on natural habitats located in the neighborhood.
