invasive species

Ecosystems are complex and fragile. When a non-native species is added to an established ecosystem, sometimes the ecosystem adjusts and sometimes havoc is wrought. When an introduced species upsets the balance of an ecosystem, we call those invasive species. Evidence has shown that marine debris can carry organisms across the ocean. As more species travel to previously inaccessible areas on rafts made of our trash, it becomes more likely that some of these species may start to disrupt the ecosystems they colonize.

We’re spending March talking all about marine debris and its types, sources, impacts, and solutions. Tune in throughout the month to learn more about this important topic and how we can all be part of the effort to make our lives and our ocean #DebrisFree.

Marine debris can have many negative effects on us and our environment. One potential impact of debris which is often overlooked is marine debris’ potential to assist in the spread of non-native, and potentially invasive, species. Non-native species, or animals that are not from a certain area or meant to be there, have the potential to become harmful and invasive. If that happens, these invasive animals can start using the local resources in an unsustainable way, or in a way that may negatively impact those animals that do belong.

The NOAA Marine Debris Program (MDP) is proud to announce the release of our new report detailing the potential of marine debris to act as a pathway for the introduction of invasive species.

There is mounting concern over the increase in debris in our ocean and the potential for that debris to assist in the spread of non-native species. While the pathways associated with global shipping draw the greatest amount of attention regarding marine invasives, the purpose of this paper is to consider the potential role that marine debris may play in introducing non-native species that may become invasive. This report reviews the scientific literature that exists on the subject and identifies areas where more research is needed.

A plastic bag may look flimsy, but in a fight against a sea turtle, it often wins. Unfortunately, the marine debris that we find floating in our oceans and waterways all too often impacts marine life.

There are many ways that marine debris can impact marine animals. For instance, the accidental ingestion of debris is a big problem! Animals may unintentionally eat debris along with their meal, or intentionally ingest trash due to its resemblance to real food.
