Invasive Alien Species (IAS) Guide 

In 2012, through the federal government's Invasive Alien Species Partnership Program (IASPP), and in partnership with dozens of organizations and individuals in the Maritimes, MTRI developed a guidebook for Invasive Alien Species in Nova Scotia. These guidebooks are available online (see thumbnails below), or printed forms can be lent from your local library, university, college, or municipal office.  

Remember: Spread the word, not the species! 


Back Cover text: 

Invasive Alien Species are a group of species that have been introduced to Nova Scotia by humans and threaten us and the environment. In the last several hundred years, many human-assisted pathways have permitted these introductions, which threaten our province's incredible biodiversity and jeopardize the health and integrity of natural ecosystems. This has, in turn, placed added pressure on our oceans, forests, and watersheds. We all depend on these vital natural resources for our own wellbeing and prosperity; it's in our best interest to take note and to take action. This guidebook outlines some of the impacts and threats presented by these species, and stewardship actions that we can all take to help provide healthy and vibrant ecosystems for future generations.
