Natives and their Invasive Look Alikes

Posted on Jun 9, 2014

While we were out birding this weekend for RTPI’s annual Bird Fest we found a number of memorable species, including several non-avian organisms. Blue flag iris (Iris versicolor) was one particular flower that was exciting to come across; however, its look alike, yellow flag iris (Iris pseudacorus), wasn’t so much.

Yellow flag iris is one of several invasive species RTPI will be reporting this summer to the NY iMapInvasives database as we work to learn more about what invasive species are here and how we can prevent their spread.
