Invasive Garlic mustard spreads across 37 US states and six Canadian provinces

The invasive plant, garlic mustard, has spread to 37 US states and six Canadian provinces, posing a threat to native ecosystems and biodiversity.

Scientists warn that the plant, which outcompetes native species for resources, is difficult to control once established.

While not directly impacting seafarers, the environmental implications may indirectly affect marine ecosystems connected to these regions.
