Distribution of invasive garlic mustard (Alliaria petiolata) along hiking trails of the Catskills

Abstract

In a time when humans are having a big impact on the environment, the arrival of non-native species creates major ecological problems. This study Investigates how Garlic Mustard, an invasive plant, spreads along hiking trails in the Catskill Mountains. The research examines the complex relationship between human activities, especially hiking, and the spread of Garlic Mustard. Surprisingly, the study shows a complicated link between the presence of hikers and the plant's spread. Garlic Mustard is very common near trailhead parking lots and along paths, but the connection between hiker activity and plant spread is not always clear. However, there are noticeable patterns suggesting a link between plant abundance, elevation gain, and distance along trails. Local factors like human-made clearings and infrastructure also affect Garlic Mustard distribution. This research highlights the need to understand the complex relationship between human actions and the spread of invasive species to create effective conservation and management strategies. It also suggests targeted actions, like education programs and manual removal methods, to stop the spread of Garlic Mustard along trail edges and into forest interiors.
