“…For example, tourist development was identified as the main determinant of non-native plant abundance and richness in study of 37 Mediterranean Islands [ 73 ]. Similarly, 152 of the 156 non-native plants recorded in Kosciusko National Park in Australia were associated with tourist infrastructure including ski resorts and hotel gardens [ 18 ], and the seeding of ski runs in the conversion of alpine habitats to ski resorts is also a source of non-native species spread to neighbouring areas [ 74 , 75 ]. A review of the links between tourist infrastructure and the abundance/richness of non-native species would add valuable further insight into the link between tourism and non-native species.…”

Managing the pathways by which non-native species are introduced and spread is considered the most effective way of preventing species invasions. Tourism and outdoor recreation involve the frequent congregation of people, vehicles and vessels from geographically diverse areas. They are therefore perceived to be major pathways for the movement of non-native species, and ones that will become increasingly important with the continued growth of these sectors. However, a global assessment of the relationship between tourism activities and the introduction of non-native species–particularly in freshwater and marine environments–is lacking. We conducted a systematic review and meta-analysis to determine the impact of tourism and outdoor recreation on non-native species in terrestrial, marine and freshwater environments. Our results provide quantitative evidence that the abundance and richness of non-native species are significantly higher in sites where tourist activities take place than in control sites. The pattern was consistent across terrestrial, freshwater and marine environments; across a variety of vectors (e.g. horses, hikers, yachts); and across a range of taxonomic groups. These results highlight the need for widespread biosecurity interventions to prevent the inadvertent introduction of invasive non-native species (INNS) as the tourism and outdoor recreation sectors grow.

“…Erosion‐control seeding with non‐native grasses is common practice on active graded ski slopes (Titus & Landau ; Burt & Rice ), but evidence of erosion‐control seeding was observed infrequently at abandoned ski areas, within only two of the ski areas (Iron Mountain and Powder Bowl). Within these areas, a total of six graded runs and five cleared runs had introduced cover attributable to seeding, primarily the long‐lived grass species Elytrigia intermedia .…”

Initial disturbance intensity affects recovery rates and successional divergence on abandoned ski slopes

Summary The importance of site history (including initial disturbance intensity and propagule arrival) in determining successional trajectories is a key theoretical and applied line of research in ecology. Abandoned ski slopes provide an opportunity to study successional processes following differing initial disturbance intensities. Some ski slopes are graded with heavy equipment when constructed (‘graded’, severe initial disturbance), while others are simply cleared of tall woody vegetation (‘cleared’, lesser initial disturbance). In a blocked chronosequence study of graded and cleared ski slopes abandoned 10–43 years previously, we found that graded ski slopes did not show predictable recovery trajectories over many decades. In contrast, cleared ski runs showed significant convergence with adjacent reference forest communities. Convergence in community composition on cleared ski runs was driven by trees, though understorey species were more numerous and dominant during succession. Understorey communities did not predictably change in species or life‐form composition over time, regardless of ski run type. Graded ski runs exhibited little or no edaphic recovery over time, showing neither reductions in bare ground and visible soil erosion, nor increases in soil depth. Cleared ski runs, in contrast, showed evidence of recovery in all of these variables except soil depth, which remained uniformly high. Synthesis and applications. The creation of new ski slopes by tree clearing is preferable to the grading of new slopes with heavy machinery, because grading reduces ecosystem function and decreases the predictability of soil and vegetation recovery decades after abandonment. Existing graded ski slopes (both operational and abandoned) may benefit from restoration of soils and vegetation.
