“…Examples include the invasion of non-native conifers such as many Pinus species, alien shrubs like Rosa rubiginosa and herbs (Fuentes-Lillo & Pauchard, 2019). Modelling the distribution of invasive species that are not at equilibrium is challenging, and recent studies have used cooccurring native community members to improve predictions (Briscoe Runquist et al, 2021).…”

“…In the Andes, modelling non‐native plants, including those that are considered invasive species should be a priority given that many of them are spreading in the region, putting biodiversity and ecosystem services at high risk (Alexander et al, 2016; Pauchard et al, 2009). Examples include the invasion of non‐native conifers such as many Pinus species, alien shrubs like Rosa rubiginosa and herbs (Fuentes‐Lillo & Pauchard, 2019).

Aim: Climate change is expected to impact mountain biodiversity by shifting species ranges and the biomes they shape. The extent and regional variation in these impacts are still poorly understood, particularly in the highly biodiverse Andes. Regional syntheses of climate change impacts on vegetation are pivotal to identify and guide research priorities. Here we review current data, knowledge and uncertainties in past, present and future climate change impacts on vegetation in the Andes.

“…Roadside environments are characterized by high rates of disturbance and reduced competition, often favoring non-native plants with more acquisitive strategies over native plants Non-native plants in the Arid Andes with more conservative strategies (Spellerberg, 1998;Tecco et al, 2010;Haider et al, 2018). Nonnatives recorded in our study area were mainly ruderal plants with broad tolerance to recurrent disturbance, also growing in other Andean regions and known as common global invaders (Fuentes-Lillo & Pauchard, 2019). Species were characterized by acquisitive strategies, mainly annuals or short-lived perennials herbs, with high relative growth rate, high seed reproduction and high Specific Leaf Area and low Leaf Dry Matter Content (Mazzolari et al, 2018).…”

“…Plant invasions in mountains are an increasing threat to biodiversity conservation as climate changes and anthropogenic disturbance increases (Pauchard et al, 2009;McDougall et al, 2011;Seipel et al, 2012;Petitpierre et al, 2016). There have been recent efforts to assess distribution and abundance of non-native plants in mountain areas around the world including in Europe (Alexander et al, 2009), Asia (McDougall et al, 2011), North America (Parks et al, 2005, Australia (McDougall et al, 2005), New Zealand (Jesson et al, 2000), and the Andes in South America (Pauchard & Alaback, 2004;Cavieres et al, 2005Cavieres et al, , 2007Badano et al, 2007;Jiménez et al, 2008; Non-native plants in the Arid Andes Fuentes-Lillo & Pauchard, 2019). Most of these studies highlighted that disturbance and environmental filtering due to increasing abiotic stress with elevation both play a critical role controlling non-native plant diversity in mountains (Alexander et al, 2011;Alexander et al, 2016).…”

While the role of environmental filters, usually described by elevation as proxy, and anthropogenic disturbance as drivers of non-native plant diversity and abundance in mountains have been extensively studied, the impact of herbivores are less explored. Livestock grazing can facilitate the introduction of non-native species by seed dispersal and reduce biotic resistance due to consumption and trampling of native plants, even in the highest protected areas in the Andes. We here explored the effects of elevation, livestock and distance to the road on non-native and native plant distributions. Our results confirm the largely negative relationship of non-native plant richness and cover with elevation, with a peak in richness and cover at low to intermediate elevations. Similarly, we show a strong decline in non-native richness with increasing distance to the road, especially at low elevations, accompanied by a strong negative effect of roads on native species richness. Most importantly, however, we show that the presence of non-native herbivores greatly increases the cover of non-native species away from the roadside, identifying herbivore disturbance as a potential catalyst of non-native plant invasion into natural vegetation of high-Andean protected areas. Our results confirm the often-shown role of disturbance as driver of plant invasions in mountains, yet highlight the interactive effects of disturbance by roads and herbivory: roads funnel non-native species towards higher elevations, while non-native herbivores can promote non-native plant success away from the roadside and into the natural vegetation. Hence, regulating soil and non-native herbivory disturbance is important for minimizing plant invasions at high elevation in the Arid Andes.

“…Although the presence of non-native species has become increasingly common in mountain regions, so far, the levels of invasions have shown to be relatively low (Pauchard et al 2009;McDougall et al 2011;Marini et al 2013;Fuentes-Lillo and Pauchard 2019). As in other ecosystems, the invasion process in mountain ecosystems is defined by the interaction between abiotic conditions, biotic interactions, and propagule pressure (Catford et al 2009).…”

Anthropogenic factors overrule local abiotic variables in determining non-native plant invasions in mountains

The factors that determine patterns of non-native species richness and abundance are context dependent in both time and space. Global change has significantly boosted plant invasions in mountains, therefore, understanding which factors determine the invasion and at what scale they operate are fundamental for decision-making in the conservation of mountain ecosystems. Although much evidence has been gathered on the patterns of non-native species in mountain ecosystems, little is known about what specific abiotic, biotic, or anthropogenic factors are driven such patterns. Here, we assessed the importance of anthropogenic, biotic, and abiotic factors at two spatial scales as drivers of plant invasions along three roads in south-central Chile.We sampled non-native plant richness and abundance, and each of these explanatory factors, in-situ in 60 transects in disturbed areas and adjacent undisturbed vegetation. Low elevation areas were the most invaded, with patterns of richness and abundance driven mainly by anthropogenic factors, explaining between 20 and 50% of the variance for the three roads. Only for the abundance of non-native species along the road in the Malalcahuello National Reserve, biotic factors were more important (45% of the variance). At the regional scale, the abundance of non-native species was again explained best by anthropogenic factors (24% of the variance), yet non-native richness was driven most strongly by abiotic factors such as soil nitrogen content and pH (15% of the variance). Our results confirm the conclusions from experimental studies that anthropogenic factors override abiotic factors and are important drivers of non-native species at local and regional scales and that non-native plant invasion in mountains is currently not strongly limited by climate.
