“…This can be explained by the disturbance hypothesis-more frequent human interference causes the habitat to produce ecological niches suitable for the growth of alien plants and thus promotes invasion. On the other hand, people and vehicles are also carriers of invasive alien plant propagules and therefore act as promoters of invasion [60,61]. Moreover, we also found the average human flow was negatively correlated with the invasibility of all three habitats.…”

Invasive alien plants have invaded various habitats, posing a threat to biodiversity. Several hypotheses have been proposed to explain the mechanisms of invasion, but few studies have considered the characteristics of the invaded communities and the effects of human interference in the invasion. In this study, we compared the invasibility of three different habitats: abandoned land, eucalyptus plantations, and natural secondary forests. We explored the effects of species diversity, phylogenetic diversity, and disturbance factors on the invasibility of different habitats. The results showed that the invasibility of abandoned land was the highest and the invasibility of the natural secondary forest was the lowest. Phylogenetic indicators affected the invasibility of abandoned land and eucalyptus plantations, and disturbance factors affected the invasibility of all three habitats, while the characteristics of the invaded communities had a weak impact. Our research provided supporting evidence for Darwin’s naturalization hypothesis and his disturbance hypothesis but found no relationship between biotic resistance and invasibility. This study indicated that the differences among habitats should be considered when we prove Darwin’s naturalization hypothesis in nature reserves.

“…This caveat applies to other species with dispersal facilitation by human operators of mechanical vectors that are accidental, e.g. recreational boating or vehicle use including off-road vehicles (von der Lippe and Kowarik 2007; Daniels et al 2019).…”

“…The quantified risk is more broadly applicable to other AIS, particularly aquatic invasive plants with similar transmission processes such as Brazilian waterweed (Egeria densa) or Eurasian Watermilfoil (Myriophyllum spicatum) that are spreading north into a warming Arctic (Kent et al 2018). Our approach is also applicable in other recreation settings including hiking (Liedtke et al 2020), watercraft-related recreation (Leung and Mandrak 2007;Muirhead et al 2009;Kelly et al 2013), or vehicle-related transmission of invasive species (von der Lippe and Kowarik 2007; Daniels et al 2019).…”

Flight plan for the future: floatplane pilots and researchers team up to predict invasive species dispersal in Alaska

et al. 2022

Aircraft can transport aquatic invasive species (AIS) from urban sources to remote waterbodies, yet little is known about this long-distance pathway. In North America and especially Alaska, aircraft with landing gear for water called floatplanes are used for recreation access to remote, often road-less wilderness destinations. Human-mediated dispersal of AIS is particularly concerning for the conservation of pristine wildlands, yet resource managers are often challenged by limited monitoring and response capacity given the vast areas they manage. We collected pathway data through a survey with floatplane pilots and used a Bayesian hierarchical model to inform early detection in a data-limited situation. The study was motivated by Alaska’s first known AIS, Elodea spp. (Elodea) and its floatplane-related dispersal. For 682 identified floatplane destinations, a Bayesian hierarchical model predicts the chance of flights originating from AIS source locations in freshwater and estimates the expected number of flights from these sources. Model predictions show the potential for broad spread across remote regions currently not known to have Elodea and informed monitoring and early detection efforts. Our result underlines the small window of opportunity for Arctic conservation strategies targeting an AIS free Arctic. We recommend management that focuses on long-distance connectivity, keeping urban sources free of AIS. We discuss applicability of the approach for other data-limited situations supporting data-informed AIS management responses.

“…For managers of large protected areas, this outcome should guide resource prioritization to locations that are major divides between forest and non‐forest rather than predominantly forested locations that are only fragmented by thin linear features such as roads and powerlines. Linear features have been proposed and modeled as likely pathways for invasion (Taylor et al, 2012; von der Lippe & Kowarik, 2012), but recent studies have found poor correlations when assessing the impact beyond the immediate road corridor (Daniels et al, 2019). Our results support the latter studies as total patch edge and distance to non‐forest land uses did show significant correlations with invasion risk but with a strength 10 times less than the land use proportions.…”

As a leading cause of forest health degradation, non-native invasive plant species are a key focus for many forest management and conservation efforts.These efforts come at a high price for resource-limited agencies and organizations making cost-effectiveness an important objective of invasion response plans. In this paper, we present an approach to guide the prioritization of locations for invasion management using species distribution models that account for the non-equilibrium of invasive species distributions and use readily available land use data as the primary explanatory variables. This approach takes advantage of the relatively high spatial resolution, as well as the broad, continuous geographic coverage, of land use data to provide results at a landscape scale relevant to practitioners responsible for invasive species management. In our example from northern Virginia, we simultaneously modeled a suite of invasive plant species to identify common indicators of invasion. We found that the proportions of surrounding non-forested land use types (grasses, crops, and development) were the most common and strongest indicators of invasion risk. These outcomes can guide managers of large protected areas to focus on major divides between forest and non-forest land over linear disturbances. We also found useful species-specific traits that can inform specific management actions. Additionally, we demonstrate through a case study how organizations that manage multiple smaller properties can take advantage of the projected distribution maps when considering acquiring or administering properties.
