Non-native invasive species frequently appear in urban and non-urban ecosystems and may become a threat to biodiversity. Some of these newcomers are introduced accidentally, and others are introduced through a sequence of events caused by conscious human decisions. Involving the general public in biodiversity preservation activities could prevent the negative consequences of these actions. Accurate and reliable data collecting is the first step in invasive species management, and citizen science can be a useful tool to collect data and engage the public in science. We present a case study of biological recording of tree of heaven (Ailanthus altissima (Mill.) Swingle) using a participatory citizen model. The first goal in this case study was to develop a cheap, widely accessible, and effective inventory method, and to test it by mapping tree of heaven in Croatia. A total of 90.61 km of roads and trails was mapped; 20 single plants and 19 multi-plant clusters (mapped as polygons) were detected. The total infested area was 2610 m 2 . The second goal was to educate citizens and raise awareness of this invasive species. The developed tool and suggested approach aided in improving invasive risk management in accordance with citizen science principles and can be applied to other species or areas.

“…Ailanthus altissima is a dioecious early successional tree species originating from China that was brought to Europe around the 1740s as an ornamental tree (Kowarik and Säumel 2007). The spread of A. altissima has often been associated with natural disturbances (Xi 2008;Maringer et al 2012;Kasson et al 2013) or disturbance caused by forest management (Call and Nilsen 2003;Radtke et al 2013;Berg et al 2017;Rebbeck et al 2017). Radtke et al (2013) found frequent clear-cuts in coppice forests to favour the establishment and spread of A. altissima in northern Italy, while the time since the last timber harvest was the best predictor of A. altissima presence and density in state forests in Ohio, USA (Rebbeck et al 2017).…”

Moreover, natural disturbances such as fire (Maringer et al 2012), windthrow (Xi 2008) or insect defoliation (Kasson et al 2013) were found to lead to an increase in the abundance and/or the area colonised by A. altissima.…”

“…Swingle. Its spread in forest ecosystems has often been associated with disturbances induced by forest management (Call and Nilsen 2003;Radtke et al 2013;Berg et al 2017;Rebbeck et al 2017) or natural processes (Xi 2008;Maringer et al 2012;Kasson et al 2013). Despite the positive association of A. altissima with disturbance, the species also proved to be capable of establishing in forests lacking a large scale disturbance by virtue of its fast juvenile height growth (Knapp and Canham 2000;Knüsel et al 2016).…”

Future forest composition is uncertain in many areas due to climate change. The spread of non-native species adds to these uncertainties, particularly in forests recently colonised by novel tree species. To anticipate future forest composition, and thus the provision of ecosystem services, a thorough understanding of the factors influencing the establishment of non-native tree species is essential. We studied the presence and abundance of regeneration of Ailanthusaltissima (Mill.) Swingle in 89 plots on a regular grid in three sites in southern Switzerland to determine the main drivers of its establishment. All sites are located in abandoned, i.e. currently unmanaged stands of Castaneasativa Mill. Propagule pressure is caused by single mature A.altissima that colonised the area ca 40 years ago. We found high rock cover, low litter cover and high light availability to be the most important predictors for the presence of A.altissima regeneration, whereas its abundance was positively influenced by high light availability, low litter cover and high browsing on regeneration of competing species. However, the presence models performed much better than the abundance models. Interestingly, the most important factors favouring the establishment of A.altissima in recently undisturbed sites were found to be similar in a nearby site after a severe forest fire, which suggests a similar establishment strategy after a disturbance as in recently undisturbed forests. Based on our results we expect a further expansion of the species in lowland forests currently dominated by C.sativa, likely controlled primarily by light availability.

“…Ailanthus altissima predominantly colonizes rapidly after forest harvests or at other sites with high light, such as road cuts [18,[51][52][53]. In fact, across South Africa, most A. altissima trees colonized within the first five years of a disturbance [53].…”

Abstract:The goal of this study was to discover the nature and intensity of the interaction between an exotic invader Ailanthus altissima (Mill.) Swingle and its coexisting native Robinia pseudoacacia L. and consider management implications. The study occurred in the Mid-Appalachian region of the eastern United States. Ailanthus altissima can have a strong negative influence on community diversity and succession due to its allelopathic nature while R. pseudoacacia can have a positive effect on community diversity and succession because of its ability to fix nitrogen. How these trees interact and the influence of the interaction on succession will have important implications for forests in many regions of the world. An additive-replacement series common garden experiment was established to identify the type and extent of interactions between these trees over a three-year period. Both A. altissima and R. pseudoacacia grown in monoculture were inhibited by intraspecific competition. In the first year, A. altissima grown with R. pseudoacacia tended to be larger than A. altissima in monoculture, suggesting that R. pseudoacacia may facilitate the growth of A. altissima at the seedling stage. After the second year, R. pseudoacacia growth decreased as the proportion of coexisting A. altissima increased, indicating inhibition of R. pseudoacacia by A. altissima even though the R. pseudoacacia plants were much larger aboveground than the A. altissima plants. In early successional sites A. altissima should be removed, particularly in the presence of R. pseudoacacia in order to promote long-term community succession.
