Every month, new species are introduced to our lands and waters, new studies are published, and new methods of control are tested—with impacts varying across the map. It would be nearly impossible to stay on top of every piece of invasive species news.
However, the staff and board of the North American Invasive Species Management Association review headlines each month. This helps us stay on top of trends and further our mission to support, promote, and empower invasive species prevention and management in North America. We then share invasive species news most relevant for people who manage terrestrial and aquatic invasive species across the the United States, Canada and occasionally the world.
So, what happened this month?
- Invasive plant managers and everyday citizens are pressing forward with prevention and detection as they navigate around new Covid restrictions.
- Phenology maps help forecast when invasive species will be at critical life stages for management in your region.
- Conversations ranged from the Borderlands’ conservation efforts in peril to the precarious position of National Parks in invasive species.
- This, and much more. Read on:
