In the cold-temperate forests of North America invasive worms are threatening forest ecosystems, due to the changes they create in the soil, including decreases in C:N ratios and leaf litter, disruption of the seed bank, and changes in soil structure . Invasive species are any species that are non-native to a particular ecosystem and whose introduction and spread causes, or are likely to cause, socio-cultural, economic or environmental harm or harm to human health. Restoration can repair habitats degraded by invasive species and may be necessary if aquatic or terrestrial ecosystems are too damaged to heal on their own. They also need to know what level of investment is appropriate, and which techniques are most appropriate for each respective situation.

Regulators have instead developed risk-assessment protocols and banned or quarantined imports of some trees and woody plants known to harbor dangerous pests.
