Field Notes
The air was chilly and strong on October 4th, 2018, on Mackworth Island, Maine. We were split up into 8-12 groups with 5-6 kids in each, to look for invasive plants around Mackworth Island. My group set out to look for our plants at around roughly 9:30. We all had various plants that we were looking for, but personally, I was looking for the invasive plant, Multiflora rose. As we voyaged down the path, on this 65-degree day, you could see the forests were filled with lots of other lush invasive plants such as Japanese barberry, Japanese knotweed, and glossy buckthorn. We did not find Multiflora rose our entire trip. We did, however, find its look-alike, Beach Rose. Its coordinates were close to 43.6995, -70.2403. It looked very much like MUltiflora Rose and we even thought it was for some time. The beach rose has almost the exact same leaf and leaf arrangement as well as a thorny stem. The Beach rose plant was rather small and hard to find. It also did not look like it was harming any other plant around it yet.
Supporting Evidence

One reason I knew my plant was NOT multiflora rose, was because the leaves were slightly smaller than those of Multiflora Rose. Multiflora Roses leaves are about 4 cm while the Beach Rose leaves are about 7 cm.

Another reason I knew the plant I found was not Multiflora rose was because of its stem. It had way more thorns than Multiflora rose, and the branch was a deeper brown as opposed to Multiflora Roses green stem.

My last piece of evidence that I had proving that the plant that I found was Beach Rose and not Multiflora Rose, was because of my plant's wrinkly leaves. Beach Rose has this quality, and Multiflora rose does not.

Hi 2018egb,

Great careful observation. You did find rosa rugosa, or beach rose. I'm glad to hear that you were not able to find rosa multiflora. Do you have a plan to monitor or control the invasives that you did see?

Keep up the great work!
