“…An understanding of the positive and negative effects of the introduction of alien species on native ecosystems is fundamental to sustainable management and to proper nature conservation policy [25][26][27][28]. It is also an essential part of assessing of the influence of the alien species on ecosystem services [29,30], especially in forests which are altered, disrupted or degraded by commercially-important but invasive plants introduced deliberately [21,[31][32][33].…”

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.

“…Black wattle yields serious negative impacts on biodiversity, water resources, and the cohesion and stability of riparian ecosystems throughout rural South Africa, while also increasing erosion (Wit et al, 2001). The extensive veld fires that raged outside Cape Town in 2000 have also been blamed at least in part on the presence of invasive species (Neely, 2010), which pull moisture from the ground and thereby encourage wildfires.…”

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.
