Despite a large increase in hiking recreation in the Coastal Mountains of British Columbia, how human trampling affects alpine plant communities that are already impacted by warming is unknown. To quantify this, we established a trampling study in Summer 2022 in the Nch’kay region (Garibaldi Provincial Park, British Columbia) as part of the International Tundra Experiment (ITEX). We established 14 paired disturbed (trail-side) and undisturbed (off-trail) transects along three major hiking trails in the Nch’kay region. At each transect, we measured maximum plant height and diameter (growth proxies), and recorded the number of buds, flowers, and fruits (reproduction proxies) for mountain heather, blueberry, and sedges. We took standardized photographs of each transect to compute plant percent cover and buried tea bags at selected transects to measure litter decomposition rates. We found that trail-side ericaceous plants were smaller than those located off-trail, suggesting lower growth rates, lower survival rates, or both. However, we found the opposite was true for sedges, with trail-side sedges being larger than those located off trail. Both of these effects were exacerbated at increasing elevation, indicating that plant communities are more sensitive to the effects of disturbance at higher elevations. We found no significant difference in reproductive outputs of species growing in disturbed or undisturbed transects. Understanding which plant types are more susceptible to the effects of human trampling than others will help inform land managers on where to establish recreational sites and trails to minimize the effects of human trampling.
