In addition, we will investigate the impact of jumping worms on soil structure and infiltration, and also study the leaf litter and soil temperature requirements of overwintering A. tokioensis and A. agrestis. It is very difficult to remove an invasive species once it is well established in an ecosystem, so the focus must be on preventing the spread of Asian earthworms. Like all earthworms, there are no research-based management options, so preventing their introduction and reducing their spread are the only two proven forms of management.
