“…The most effective methods for detection (e.g. traps or visual inspections) and the mix between passive and active surveillance (Hester and Cacho 2017) will depend on the biology of the organism. Similarly, it is important to understand the context of the invasion, going beyond whether pathways still operate to consider factors that might limit invasions (e.g.…”

Increased trade and travel have resulted in an increasing rate of introduction of biological organisms to new regions. Urban environments, such as cities, are hubs for human activities facilitating the introduction of alien species. Additionally, cities are susceptible to invading organisms as a result of the highly altered and transformed nature of these environments. Despite best efforts at prevention, new incursions of alien species will occur; therefore, prioritising incursion response efforts is essential. This study explores these ideas to identify priorities for strategic prevention planning in a South African city, Durban (eThekwini), by combining data from alien species watch lists, environmental criteria, and the pathways which facilitate the introduction of alien species in the city. Three species (with known adverse impacts elsewhere in the world) were identified as highly likely to be introduced and established in Durban (Alternantheraphiloxeroides,LithobatescatesbeianusandSolenopsisinvicta). These species are most likely to enter at either the Durban Harbour; pet and aquarium stores; or plant nurseries and garden centres – therefore active surveillance should target these sites as well as adjacent major river systems and infrastructure. We suggest that the integrated approach (species, pathways, and sites) demonstrated in this study will help prioritise resources to detect the most likely and damaging future incursions of alien species.

“…This result may be explained by the fact that we focus mainly on plantations with native pine species (with the exception of Pinus radiata). Moreover, they can also be explained because planted forests might benefit from early warning systems due to the various silvicultural operations and planning that often take place in these forests [15]. Weaker evidence was found with respect to invasion of birds or mammals, probably because they are more weakly linked to the characteristics of the studied habitat due to being species that move.…”

“…The numbers of newly established alien species are still increasing [9] with socio-economical, technological, and environmental changes leading to novel patterns of plant introductions and invasionopportunities [10,11]. As a result, prevention, monitoring, invasions and early detection of new alien species naturalisations are seen as priorities for management [12][13][14][15]. However, predicting the invasion potential of species is complex as it depends of context specific information linked to the transport mode of a species, the number of introduced species, the frequency of introduction, the time that has elapsed since a species was first introduced, and the actual biology and ecology of an introduced species (e.g., [2,12,[16][17][18][19]).…”

Abstract:Plantations with alien forest species could be a major way for invasive plant and animal species to become introduced and naturally established in a territory, but the sensitivity of plantations with native forest species to invasive plant and animal species is still unknown. This paper studies the probability of the presence and the richness of invasive species of three different taxa (plants, birds, and mammals) in pine forests of southwestern Europe. To do so, the relative contribution from natural and planted forests is analysed to explain the presence and the richness of invasive species in 3950 cells (10 km × 10 km) covering Spain after controlling for the possible effects of variables related to geography, climate, land use, landscape, and human pressure on the environment. Our results show that man's influence on the establishment of invasive species is notable. However, those forests that are the most intensely managed by man, such as pine plantations with native species, seem less susceptible to the establishment and propagation of invasive species. Reasons may be found in those planted pine forests being closely monitored, controlled, and managed by man. Therefore, it is argued that efforts related to the early warning systems of invasive species should be focused on natural pine forests.

“…Most of the existing literature has focused on active surveillance (e.g., planned visual or trapping surveys), but passive surveillance in the form of public reporting also serves as a key source for new detections (Hester and Cacho 2017). This has been incorporated into some optimal surveillance work by simply assuming that a population of an established pest will be detected after some time period on the landscape if not detected by a trap (Epanchin-Niell et al 2014).…”

This article examines the use of economic analysis to inform bioinvasion management, with particular focus on forest resources. Economics is key for understanding invasion processes, impacts, and decision-making. Biological invasions are driven by and affect economic activities at multiple scales and stages of an invasion. Bioeconomic modeling seeks to inform how resources can be optimally allocated across invasion management activities-including prevention, surveillance programs for early detection and management, and controlling invasion populations and spread-to minimize the long-term costs and damages. Economic analysis facilitates understanding of decisions by public and private decision-makers, gaps between these, and the design of policies to achieve socially desirable outcomes. Private decisionmakers may undercontrol invasions relative to socially optimal levels, because they generally account for their own costs and benefits of control but less often for broader ecosystem impacts or future spread across the landscape. Economic analysis considers approaches for increasing private invasion management and evaluates feedbacks between ecological and economic systems that can affect policy outcomes. Future research should continue evaluation and design of control strategies across the biosecurity continuum and across species to enhance cost-effectiveness, better incorporate uncertainty into policy design, increase focus on incentives and behavioral tools to influence private behaviors that affect invasion spread, and incorporate invasive species consideration within broader systems-focused science. In addition, challenges in valuing biodiversity and ecosystem service impacts and the costs and effectiveness of control measures are key data gaps. Greater collaboration between decision-makers and researchers will facilitate development and communication of usable economic research.
