Invasive species can spread through various pathways, including natural dispersal and human activities. Human-mediated pathways include international trade, tourism, and transportation, where species are accidentally transported across regions. Additionally, aquaculture, the pet trade, and horticulture often contribute to the introduction of non-native species. These pathways enable invasive species to establish themselves in new environments where they may not have natural predators or competitors, allowing them to thrive and spread rapidly.
