This paper presents an invasive plant species that occur in the forests of Kalnik. It also presents the state of the distribution and their impact on forests of Kalnik. A total of 14 invasive species in the forests of Kalnik and these are – Acer negundo L., Ailanthus altissima (Mill.) Swingle, Ambrosia artemisiifolia L., Amorpha fruticosa L., Asclepias syriaca L., Conyza canadensis (L.) Cronquist, Echinocystis lobata (Michx.) Torr. et Gray, Erigeron annuus (L.) Pers., Impatiens glandulifera Royle, Juncus tenuis Willd.), Phytolacca americana L., Reynoutria japonica Houtt., Robinia pseudoacacia L., Solidago gigantea Aiton. Alochtonous vegetation is not only inevitable, but it also appears to be a constant future challenge in the globalizing world which communicates on all levels with every means possible. Its influence should not by any means be marginalized. Its importance and influence is not completely negative and there are possible benefits and dangers which should be controlled by the preventive measures and physical regulation. The most important species in Kalnik forest vegetation is definitely acacia. It is especially important for private forest lands where acacia tree has become very popular because of its characteristics as a fast growing tree species without any special requirements with relation to growth and it gives fast results concerning timber and firewood. Private lots are usually very small and fragmented. There is a growing need for timber, therefore the trees are grown extensively, from stumps and roots. Other woody species still do not pose a serious threat in economical or biological sense. The impact of herbaceous plants differs in various areas. The most problematic issues for the forestersare thick layers of unwanted specieswhich grow in young forest stands or in forests in the phase of restorationwhere these unwanted speciesinvasively compete with autochthonous species. In biological sense, invasive species pose a constant threat not only to domestic vegetation and biodiversity, but also to human health. We should also mention apiculture, a very important and well developed activity on Kalnik. Above mentioned species are very important and interesting for apiculture as a type of rich bee pasturage. Apiculture in this area depends on acacia pasturage and it is one of very important reasons for growing acacia tree. Other tree species are also valuable for bee pasturage, especially late in autumn when there is no other bee pasturage available and they are mostly species which blossom in autumn and represent a valuable source of pollen (Japanese Knotweed, Prickly cucumber and European goldenrod). Generally speaking, the biggest responsibility for possible consequences of invasive plant species to the vegetation of Kalnik lies on foresters who have to recognize and monitor the appearance of invasive species, especially in state forest lands where they grow and directly influence their composition and state.

AbstractThe purpose of this study was to determine the effect of whole-plant composting on the viability of seeds and other propagules of the invasive plant species waterhyacinth, waterlettuce, hydrilla, and giant reed while producing a valuable compost product. Invasive species were subjected to preliminary germination and growth tests and oven mortality tests to evaluate whether species distribution was via seeds, vegetative propagules, or both, as well as whether the composting process had the potential, through the high temperatures obtained, to kill seeds and other propagules. Germination and growth tests determined the means by which invasive species spread. Oven tests determined the temperatures at which unscarified and scarified seeds and propagules were rendered inviable. Achieving temperatures of at least 57.2 C was necessary within constructed compost piles to effectively kill the plants without the danger of redistribution. In the field, the study successfully developed a large-scale composting operation using invasive plant species as the primary feedstock. Analysis of field-scale composting showed final materials were within satisfactory to ideal levels for samples analyzed by the U.S. Compost Council's Seal of Testing Assurance Program and were, therefore, a valuable compost product.

Invasive Plant Species

Historically, and based on the latest conditions, Samboja Research Forest has a fairly high vulnerability to the presence of invasive species that can interfere with ecosystem stability and forest succession. However, data collection and risk assessment of invasive species have not been conducted in the forest area. The study was carried out to support the management of Samboja Research Forest, particularly in controlling invasive species. The study was conducted with exploration techniques in open areas, secondary forests, and primary forests. The density and frequency data of invasive plants were obtained using random plots in secondary and primary forest areas. The results showed the presence of 52 invasive plant species in the Samboja Research Forest area with dominance by shrubs and herbs. Based on plants distribution and density, four crucial invasive plant species in Samboja Research Forest were identified, namely: Acacia mangium, Spathodea campanulata, Miconia crenata, and Piper aduncum. The management of invasive species was carried out in two stages, short term, through manual weeding, and in the long term, with the prevention, eradication, and periodic risk assessment.Keywords: invasive alien species, Kalimantan, eradication, Spathodea campanulata

When researchers and managers are asked to rank the issues that prevent adequate control of invasive species, lack of public awareness is at the top of the list (Dehnen‐Schmutz et al. 2018). It is therefore imperative to raise the general public's awareness of the potential risks of introducing alien species into the wild. Green Pioneers, a citizen science project funded by the Flemish Government, (Fig. 1) aims to address this issue in Belgium, across age groups. The project aims to Create awareness on invasive species, highlighting how invasions can be avoided and how to mitigate their impact. Improve communication between citizens and scientists on conservation and invasive plant species. Augment the quality and quantity of data on invasive species. Create awareness on invasive species, highlighting how invasions can be avoided and how to mitigate their impact. Improve communication between citizens and scientists on conservation and invasive plant species. Augment the quality and quantity of data on invasive species. The project is developing three kinds of activity, specifically to attract a broad demographic: - 'Young Pioneers', by developing tools for teachers in science, technology, engineering and mathemathics for school children from 12-15 years old. - 'Online Pioneers', through our online citizen science platform DoeDat.be, by helping with the transcription of label information on herbarium specimens, - and 'Visiteers', by inviting companies and working age people to help us in the collection and to inform them about invasive species. Finally, we will be organizing a BioBlitz in spring 2020 at Meise Botanic Garden where we will celebrate plants and all our Green Pioneers, while also spreading the message of invasive plant awareness. During our 48 hour BioBlitz, scientists, volunteers and citizens are workig together to survey the biodiversity of our Botanic Garden. Ultimately, Green Pioneers aim to encourage recording of alien species by amateur botanists and create a generation of responsible gardeners who understand the consequences of releasing invasive alien plants into the wild.

Aims: This study aims to predict the future geographic distribution shift of invasive plant species Austroeupathorium inulifolium as the impact of global climate change. Study Design: The rising temperature and precipitation change lead to the geographic distribution shift of organisms. A. inulifolium belongs to invasive plant species that often causes a substantial economic loss and ecological degradation in the invaded areas. Modelling of species distribution using the climate-based model could be used to understand the geographic distribution shift of invasive species in the future scenario under global climate change. Place and Duration of Study: Center for Plant Conservation and Botanic Gardens – LIPI and 6 months. Methodology: The total 2228 of occurrence records were derived from the Global Biodiversity Information Facility (GBIF) database. The seven climatic variables were selected from 19 variables using a pairwise correlation test (vifcor) with a threshold >0.7. The ensemble model was used by combining Random Forest (RF) and Support Vector Machine (SVM). Results: Both two models are well-performed either using AUC or TSS evaluation methods. RF and SVM have AUC >0.95, and TSS >0.8. The predicted current distribution tends to have larger distribution areas compared to observed occurrence records. The predicted future distribution seems to be shifted in several parts of North America and Europe. Conclusion: The geographic distribution of invasive plant species A. inulifolium will be shifted to the Northern part of globe in 2090. Mean temperature of driest quarter and precipitation of warmest quarter are the two most important variables that determine the distribution pattern of the A. inulifolium. The predictive distribution pattern of invasive plant A. inulifolium would be important to provide information about the impact of climate change to the geographic distribution shift of this species.

The problem of invasive plant species is becoming more popular all over the world. The peculiarities of alien plant species is also growing in Latvia every year. Invasive species are the serious problem for natural ecosystem and species protection, in traditional landscape visual conservation as well it shows noticeable economical reducing in farming. Existing flora and its structure was as appearing in approximately 10 000-15 000 years after the last examining. It is still developing, quantitative and qualitative plant changes continue to grow in flora. That has an influence on natural narrowing, distribution and species changes. In Latvia, as well in such city as Daugavpils, such questions as alien plant growing were examined only in some fragments. An alien plant growing was analyzed. The following facts are found the biggest plant concentration is noticed in dry and sunny places well near the artificial plant areas.

AbstractInvasive plant species are a growing concern in global biodiversity management. In this study, we tried to determine whether invasive plants could spread from railway track into the surrounding areas and focused on the factors responsible for the invasive plant species composition, richness, and abundance. We sampled invasive species along transects located outside a railway route and recorded the invasive species richness and abundance at a distance of < 5 (control), 5–10, 10–15, and > 15 m away from the railway edge in three geographical regions in SE Poland. We revealed that the mechanism allowing alien species to invade was complex. Canonical correspondence analysis (CCA) explained 30.9% of variance. On a regional scale, the invasive flora composition in the surroundings of railway habitats was determined by abiotic environment diversity (mean annual air temperature, mean annual precipitation), but not habitat-related factors (soil type, soil properties). On a spatial scale, the traffic volume, the distance from the railway area, the distance from build-up areas, and the interaction of these factors affect the invasive species composition away from railway areas. The invasive species spread from railways to the surrounding vegetation, therefore, regular monitoring of railway areas should be a framework for assessing the risk of invasive species.
