Field Notes
Our quadrat was set up in Fort Williams Park in Cape Elizabeth. We were happy to be outside without the predicted thunderstorm. Clouds, people, and cars were visually observed. It felt very humid and hot with the sun beating down on our quadrat. We heard people, cars, and birds in our area. The slight scent of flowers was evident. Our biggest surprise was the number of species that co-existed with an invasive in our quadrat. We surmised this occurred due to the edge of our quadrat being so close to the walkway.

Supporting Evidence

I think we found Rosa rugosa at our study site because the stems are very, very thorny.

The leaves appear to be wrinkly.

The shape of the fruit is round. An extended branch outside of our quadrat has a bright pink flower.

Comments

You're correct in your identification; the rose is "Rugose Rose" or "Salt Spray Rose" or "Beach Rose", which are all common names for Rosa rugosa. The fact that a plant has three common names is an indication that it is important to a lot of people ... plants that aren't important to people usually get overlooked, and not named.

And two of the common names for this plant give a hint at why people think it's important: it's not only a beautiful plant (lovely flowers and fruits), but it also tolerates growing conditions like beaches, and places where the ocean's salt spray limits the plants that might survive.

Unfortunately, this plant is such a great survivor that it has become invasive! Thanks for mapping this plant, and for thinking about why plants grow where they do.

Great stem photo! Your photo demonstrates that beach rose is not a very inviting plant. You mention that natives are able to live in the same area an the invasive beach rose, did you notice any traits of the natives that might help them survive?
