AbstractMany municipalities in Central Europe deal with the problem of invasive species in their natural ecosystems. Invasive vegetation eradicates native species and causes dense stands that damage the natural environment. This work shows how important it is to have an informative tool for municipalities to be successful in their struggles with invasive species. A Driver – Pressure – State – Impact - Response (DPSIR) framework is a decision - making tool, and this one is particularly applied to the species Fallopia japonica. Fallopia japonica is an extremely invasive and aggressive weed, and it is very often found in riverbank vegetation. This specific framework can be used as a tool for municipal managers to highlight all the problems with Fallopia japonica and define all the responses that should be provided by the municipalities. The work points out the steps that show how important it is to have a strategy or a clear concept of how to begin with such a serious issue as the presence of Fallopia japonica in riverbank vegetation and its eradication. This framework provides simple steps that cannot be excluded when a municipality start actions against Fallopia japonica. All the indicators used in the model are based on the information known about Fallopia japonica that are presented in the literature.

Abstract. The seed bank response of five pioneer plants, including Cynodon dactylon, Setaria viridis, Amorpha fruticosa, Alternanthera Philoxeroides and Xanthium sibiricum, to flooding were tested through simulating the flooding experiments. The flooding treatments included 30d, 60d, 90d and the control. All of the treated seeds were germinated under an appropriate germinate condition. The results showed that seed germination rate and germination index of Amorpha fruticosa and Xanthium sibiricum increased with the increasing flooding time meanwhile that of Setaria viridis and Alternanthera Philoxeroides decreased, and Cynodon dactylon germination decreased firstly and then increased with the increasing flooding time. The results suggested that flooding influenced significantly seed germination, and implicated that Amorpha fruticosa, Cynodon dactylon and Amorpha fruticosa were appropriate species for the construction of artificial seed bank to restore riverbank vegetation in the Three Gorges reservoir area.

River management using the eco-hydraulic approach is aimed at preserving the ecological components in the river environment through hydraulic engineering. This study aims to identify the existing conditions on Kuin River border, analyze the relationship and influence of community activities on the banks of Kuin River on the water quality of Kuin River, and study the river development pattern with the concept of eco-hydraulic on Kuin River. Data were collected based on the results of field surveys and laboratory tests for water and soil. The results showed that the current condition of the riverbank of Kuin River has not fulfilled its function as a buffer space between the river and the mainland, due to the large number of community settlements rather than vegetation that functions to protect the river. Kuin River is polluted because several ecological indicators such as pH, Fe, BOD, and COD have exceeded the maximum allowable limits. This occurs due to social activities and development along the river, which have an impact on biotic and abiotic aspects of the river. The type of soil on the banks of the Kuin River is silt mixed with clay with moderate to high plasticity. Based on this condition, there is an assumption that the cliffs on the banks of Kuin River have the potential for landslides. Therefore, a pattern for developing cliff protection using riverbank vegetation components is recommended

Abstract. Syahbudin A, Meinata A, Arifriana R, Wiyono. 2020. The composition of undergrowth vegetation in the Gendol Riverbank, Sleman District, Yogyakarta, Indonesia. Biodiversitas 21: 1786-1792. Gendol river is one of the rivers affected by a pyroclastic blast from Mount Merapi eruption in 2010. This river flows through several villages, such as Glagaharjo, Kepuharjo, Wukirsari, and Argomulyo. On this riverbank, vegetation has grown naturally post-eruption of Mount Merapi and is continues to change. Some vegetation was also planted by the community. This study aims to find out the composition of the undergrowth vegetation on the Gendol riverbank in Cangkringan Sub-district. The data was obtained systematically by marking 10 sample plots of 5 m x 5 m and 2 m x 2 m size, on each side of the bank. A total of 68 species were recorded in this study which consisted of 29 trees species in seedlings and saplings stage, 34 species of herbs and shrubs, and 6 species of grasses. The dominant among the non-tree species are Chromolaena odorata (L.) R.M.King & H.Rob. with an IVI of 43.78%, Alternanthera brasiliana (L.) Kuntze with IVI of 16.6% and Asystasia gangetica (L.) T. Anderson with IVI of 15.78%. Saplings are dominated by Falcataria moluccana (Miq.) Barneby & J.W. Grimes with IVI of 32.81%, followed by Leucaena leucocephala (Lam.) De Wit (IVI-24.41%) and Melia azedarach (IVI-14.28%).

Riverbank Vegetation

The hypotheses that litter deposition on riverbanks would depend on riverbank features and that litter mass would affect riverbank vegetation were tested by sampling vegetation, litter, and soil along a seventh-order stretch of the unregulated Vindel River in northern Sweden. Sampling was carried out within a horizontal litter gradient at the top of the riverbank where most of the litter deposition occurs. The amount of leaf litter left on the riverbank after flooding was significantly correlated (P < 0.05) with soil organic matter. In contrast, wood litter mass and total litter mass were not correlated (P > 0.05) with riverbank features such as soil organic matter, riverbank slope, or stem density. Species richness, species diversity, and the proportions of stemmed and nonstemmed species showed quadratic relationships (P < 0.05) with leaf litter mass, whereas ground vegetation cover decreased monotonically (P < 0.05) with increasing leaf litter mass. Tall, stemmed species were most frequent at eroded sites with low amounts of leaf litter and at sites where leaf litter had accumulated. In contrast, the highest proportion of low-growing species was found at sites with intermediate leaf litter masses. Community characteristics such as species richness, species diversity, and the proportions of stemmed and nonstemmed species (but not ground vegetation cover) were less strongly correlated with wood litter mass and total litter mass. Linear equations explained about half of the variation in ground vegetation cover along gradients of wood and total litter masses. Density and richness of seeds increased with increasing litter mass. We discuss the litter effects in terms of productivity and disturbance and conclude that flooding in pristine rivers may exert a considerable influence on riverbank vegetation as a result of litter displacement.
