3 years ago in Invasion Biology By Md Naseer Shah

How can a country possess both source and recipient habitats in invasive biology?

While studying invasion pathways in my region, I've realized that nations like mine are often listed as both the origin and the destination for different invasive species. This seems conceptually important for policy. I'm trying to articulate this dual role clearly for a models and management paper I'm writing.

In my work with global invasion databases, this is a standard, not an exceptional, scenario. A country is a "source" when native species, often via trade goods, are transported elsewhere and become invasive. It's a "recipient" when non-native species arrive via imports or travel and establish in its ecosystems. For instance, the US is a source of the black locust tree in Europe and a recipient of the Asian carp. It reflects the multidirectional nature of global trade.
