Hello, there is a blue dune grass that google and Seek identifies in the leymus family....perhaps Leymus arenius that has been taking over our part of the dune. it is nearly impossible to get rid of and I don't see it in this area otherwise. I am very concerned it might become a new invasive species. I understand it benefits erosion issues and is made for dunes but I am not sure that is okay with the native grasses surrounding . Should I be concerned? If so, how should I deal with this? Are there companies or dune restoration people who can help? we are very close a state park

Thanks for your question.
Without seeing its inflorescence (flowering structure), it is not possible to positively identify this grass. After it produces the inflorescence, you can compare it with online images.
Blue dune grass (Leymus arenarius) is not currently on the Oregon Department of Agriculture Noxious Weeds list - https://www.oregon.gov/oda/programs/weeds/oregonnoxiousweeds/pages/aboutoregonweeds.aspx
You didn't specify which Oregon state park is in your vicinity. Recommend you contact that park directly to see if they might be able to assist you with identification. They may also be able to let you know if they have any concerns about this grass.
You could also try contacting the Oregon Department of State Lands to see if they have any concerns - Shawn Zumwalt<personal data hidden>
