“…Admittedly, the majority of new generation of tree stands in the studied timber forest are artificially planted, spontaneous forest restoration is rarely used, but the abundant self-reproduction of Q. rubra and its ability to create numerous stump sprouts after cutting, which is common in its native range [42,86], and which has been observed in European forests [46,52] may make forest regeneration after Q. rubra felling significantly more difficult. The vegetative reproduction of Q. rubra by re-sprouting may ensure its establishment and long-term maintenance in the POF habitat and the increasing local reproductive pressure of this alien tree may lead to its higher invasiveness [87,88]. In a negative scenario the uncontrolled spread of Q. rubra limits or ultimately displaces native species in the POF ecosystem.…”

The negative impact of intentionally introduced Quercus rubra L. on a forest community

Some alien woody species used in commercial forestry become invasive and, as invaders, cause major problems in natural and semi-natural ecosystems. However, the deliberate introduction of aliens can bring unintended negative changes also within areas of their cultivation. This paper presents the effects of the intentional introduction of the North-American Quercus rubra in European mixed Scots pine-Pedunculate oak forests (POFs): Querco roboris-Pinetum (W. Mat. 1981) J. Mat. 1988. Phytosociological data from field research combined with GIS data analysis of the current distribution of Northern Red oak in the studied habitat were used to determine the composition and structure of forest communities in plots with and without Q. rubra participation. The results show that Q. rubra significantly reduces native species richness and abundance, both in old-growth and in secondary (post-agricultural) forests. Not one resident vascular plant benefits from the introduction of Northern Red oak and only a few are able to tolerate its co-occurrence. The natural restocking of all native woody species is also strongly limited by this alien tree. The introduction of Northern Red oak significantly limits the environmental functions of the POF ecosystem and weakens its economic and social aspects. However, its further cultivation is justified from an economic point of view, as the essential function of the studied forests is commercial timber production, and the introduction of this fast growing alien tree supports the provisioning ecosystem services. A clear description of the level of trade-off between the accepted negative and positive effects of the introduction of Q. rubra on forest ecosystem services requires further interdisciplinary studies.

“…Many intentionally imported alien species are of a high economic value (DiTomaso et al 2010, Richardson and Rejmánek 2011, Woziwoda et al 2014), but can have negative impacts on native populations, species and communities due to a wide range of mechanisms and processes that have been described in the literature in the last decade (e.g. Levine et al 2003, Gaertner et al 2009, Mitchell et al 2010, Pyšek and Richardson 2010, Vilà et al 2010, Dodet and Collet 2012, Pyšek et al 2012c, Scalera et al 2012. However, although these processes are becoming reasonably well understood, there is still much uncertainty about which particular species will have an impact in specific environmental settings and how the invaded habitats and ecosystems will be impacted (Leung et al 2012.…”

NeoBiota 28: 1-37. doi: 10.3897/neobiota.28.4824 AbstractAs legislation, research and management of invasive alien species (IAS) are not fully coordinated across countries or different stakeholder groups, one approach leading to more or less standardized activities is based on producing lists of prominent IAS that attain high level of concern and are a subject of priority monitoring and management. These so-called Black, Grey and Watch (alert) Lists represent a convenient starting point for setting priorities in prevention, early warning and management systems. It is important that these lists be based on transparent and robust criteria so as to accommodate interests and perception of impacts by groups of concerned authorities and stakeholders representing sectors as diverse as, e.g. forestry, horticulture, aquaculture, hunting, and nature conservation, and to justify possible trade NeoBiotaJan Pergl et al. / NeoBiota 28: 1-37 (2016) 2 restrictions. The principles for blacklisting need to be general enough to accommodate differences among taxonomic groups (plants, invertebrates, vertebrates) and invaded environments (e.g. aquatic, terrestrial, urban, suburban, seminatural), and must take into account invasion dynamics, the impact the IAS pose, and management strategies suitable for each particular invader.With these assumptions in mind, we synthesize available information to present Black, Grey and Watch Lists of alien species for the Czech Republic, with recommended categorized management measures for land managers, policy makers and other stakeholders. We took into account differences in the listed species' distribution, invasion status, known or estimated environmental impact, as well as possible management options, and apply these criteria to both plants and animals. Species with lower impact, but for which some level of management and regulation is desirable, are included on the Grey List. Some potentially dangerous species occurring in European countries with comparable climatic conditions, as well as those introduced in the past but without presently known wild populations in the Czech Republic, are listed on the Watch list. In total, there are 78 plant and 39 animal species on the Black List, 47 and 16 on the Grey List, and 25 and 27, respectively, on the Watch List. The multilayered approach to the classification of alien species, combining their impacts, population status and relevant management, can serve as a model for other countries that are in process of developing their Black Lists.

“…We identify a number of factors that are possible for the successful invasion by A. mearnsii at the Changshui airport, and group them into environmental factors, human disturbance and weed characteristics. Dodet and Collet (2012) highlighted that invasion may become effective only when environmental conditions allow the species to express their potential for invasion. In this case study, the land claimed as the airport were villages, farmland and planted forests (including planted black wattle forests) prior to the con-struction of the airport in 2007, which probably resulted in extensive A. mearnsii seed banks that were spread and concentrated in the grass-planting area and in the planning area.…”

“…They are often referred to as naturalized alien (exotic or non-native) plants that establish and maintain their population by self-reproduction and self-diffusion at considerable distances from the parent plants, and have become harmful species, to some extent, or have had a negative influence on humans (Lamarque et al 2011;Pyšek et al 2004;Richardson et al 2000). These species are characterized by easy establishment, fast growth and high propagule pressure (Dodet and Collet 2012).…”

Acacia mearnsii De Wilde is on the top 100 of the world's most invasive alien species and has successfully invaded many areas around the world. However, its distribution and expansion is seldom reported in China. This study for the first time conducted a survey on the new distribution of A. mearnsii at the Kunming Changshui Airport (Yunnan Province, China), through monitoring on population characteristics (number, density, height and ground diameter) and spatial distribution (spread distance). Our survey results show that A. mearnsii has spread rapidly across the airport. This study discusses three factors of environmental factors, human disturbance and weed characteristics behind this successful invasion. The species invasion has a strong potential to change the local vegetation structure, enhances the probability of bird strikes at the airport, and is vulnerable to invade new biogeographic regions if it is not controlled. Currently, eradication combined with mechanical control is considered to be the best option for control. Our study helps improve awareness about the potential risk of A. mearnsii invasion in other airports around China and the world.
