Utilization of the invasive plant Impatiens parviflora DC. by the snail Columella edentula Draparnaud in oak-hornbeam forests

This study investigated the extend to which the snail Columella edentula is more strongly associated with the small balsam Impatiens parviflora than with other plants in the herb layer of an oak-hornbeam forest, and to interpret the character of the interaction Impatiens parviflora - Columella edentula. Numbers of C. edentula and rates of colonization were compared on various plant species under natural and laboratory conditions. Seasonal variation in snail abundance on I. parviflora was observed on permanent plots. The leaf injuries caused by C. edentula were localized in respect of the morphological and anatomical structure of leaves. The results show that I. parviflora is one of the plant species of the herb layer that are most abundantly colonized by this snail in oak-hornbeam forest. Snail finds a plant particularly suitable as a place for resting. The most favoured attachment site is on the underside of the leaf, along the midrib, which provides the highest and relatively stable humidity, as well as protection from direct sunlight and predators. I. parviflora is also a food for the snails, but they do not eat these fragments of leaves where calcium carbonate is accumulated.

Impatiens parviflora is non-native invasive plant species occupying large areas all over the Europe and threatens native communities by altering their species composition and reducing native biodiversity. The factor responsible for its spreading could be explained by releasing biochemical to the environment. On the other hands, high demand on secondary metabolites as potential source of new ecofriendly biocides could be beneficial. The analysis of I. parviflora essential oil (EO) led us to identify more than 60 volatiles. The main compound was hexahydrofarnesyl acetone, other dominant components were phytol, carvacrol, germacra-4(15),5,10(14)-trien-1-α-ol, and pentacosane. The potential phytotoxic effect of I. parviflora EO collected in two vegetation periods (summer and autumn) was evaluated on seed germination and root elongation of three dicot species (Raphanus sativus, Lepidum sativum, and Lactuca sativa) and on one monocot species (Triticum aestivum). The seed germination of only one dicot species, L. sativa, was affected by both EOs. In contrast, seed germination of monocot species T. aestivum was influenced only by the highest doses of EOs isolated from I. parviflora in autumn. The root elongation of tested plant species was less influenced by I. parviflora EOs. L. sativum showed sensitivity to one dose of EOs hydrodistilled in summer, while the monocot species was influenced by both EOs samples in highest doses. Our findings revealed that I. parviflora contained phenolics that were phytotoxic to the germination of some plant species, mainly at higher EOs doses, while root elongation of tested plants was not suppressed by essential oils.

Between 1996–2002, successional dynamics on an abandoned pasture in Přední Ždírnice (lat. 50°32’N, long. 15°40’E) was examined. A 7-year study was performed on the abandoned mesotrophic pasture classified as Cynosurion Tüxen 1947 at the start of the study. Two permanent plots (100 m2) were established and sampled three times a year; changes in plant species composition (species cover) and plant species diversity (species number) were studied. Species assemblages of the Cynosurus pasture were described, E1 (herb layer) and E2 (shrub layer) covers were calculated and a secondary succession in the plant community was evaluated. Abandonment caused the decrease in the cover of the species sensitive to shading – e.g. Taraxacum sect. Ruderalia, Trifolium repens, Lathyrus pratensis, Plantago major, Stellaria graminea, Vicia cracca. Contrary to this, the cover of Calamagrostis epigejos, Rubus sp., Galium album, Galium verum, Knautia arvensis, Veronica chamaedrys increased, probably due to their ability to spread by clonal growth and as a result of the competitive relationships in the plant community. A big production of Calamagrostis epigejos litter may be the outcome of a significant decrease (by 9%) in E1 cover (P = 0.04). Although the grassland was invaded by ruderal and weedy species (Apera spica-venti, Myosotis arvensis, Veronica arvensis) and by shrubs Crataegus sp. and Rosa sp. (an increase by 16%), an increase in species number was not significant. Phytosociologically, the Cynosurion Tüxen 1947 community came closer to the Arrhenatherion Koch 1926 alliance.

AbstractDuring the field studies on the floodplain forests of the Małopolska Upland carried out in 2009-2013, the author tried to determine which species of alien and invasive plants could be a threat to the stability of these vegetation communities. Efforts were also made to answer the question, which floodplain forests are particularly vulnerable to the penetration of alien species and in which layers of the forest plant community are the best conditions for the development of the individual alien plant species. During the research, a total number of 344 reléves were made, of which 90 recorded the presence of alien species. The most common were: Impatiens parviflora, Acer negundo and Padus serotina. The highest percentage of reléves involving alien species was found in the riverside floodplain forests of Salicetum albo-fragilis and Populetum albae.

Impatiens Parviflora

Abstract In recent years, programmes aimed at improving environmental conditions in river valleys within urban spaces have been initiated in many of the European Community countries. An example is the project “Revitalization of Urban River Spaces – REURIS” which was implemented in 2009-2012. Its main aim was to revitalize a part of the valley of the River Ślepiotka in Katowice. One of the tasks of the project was a comprehensive treatment to combat invasive plant species occurring in this area, carried out by using a combination of chemical and mechanical methods. Chemical treatment involved the application of herbicide mixtures, and mechanical treatment included, among others, mowing and/or removal of the undesirable plants. The work focused primarily on reducing the spread of two species of the Impatiens genus: I. glandulifera and I. parviflora, and the species Padus serotina, Reynoutria japonica and Solidago canadensis. Currently, the maintenance works on this section of the river are performed by the Urban Greenery Department in Katowice, which continues the elimination of invasive plants, according to the objectives of the REURIS program. In 2012 the Department of Botany and Nature Protection at the Faculty of Biology and Environmental Protection started to monitor the implementation and the effects of the implemented actions for elimination and participated in the action of removal of selected invasive plant species: Impatiens parviflora and Reynoutria japonica within specific areas. These actions led to a reduction in the area occupied by invasive plants and a weakening of their growth rate and ability to reproduce.

The City

Invasive alien species (IAS) is a global problem that largely relates to human activities and human settlements. To prevent the further spread of IAS, we first need to know their pattern of distribution, to determine which constitutes the greatest threat, and understand which habitats and migration pathways they prefer. Our research aimed to identify the main vectors and distribution pattern of IAS of plants in the city environment. We checked the relations between species distribution and such environmental factors as urban soil type and habitat type. We applied data on IAS occurrence (collected in the period 1973–2015) in 515 permanent plots with dimensions of 0.5 × 0.5 km and analyzed by direct ordination methods. In total, we recorded 66 IAS. We found a 27% variance in the IAS distribution pattern, which can be explained by statistically significant soil and habitat types. The most important for species distribution were: river and alluvial soils, forests and related rusty soils, and places of intensive human activities, including areas of urbisols and industriosols. Our results provide details that can inform local efforts for the management and control of invasive species, and they provide evidence of the different associations between natural patterns and human land use.
