Field Notes
On Thursday October 4, our crew travelled to Mackworth Island on our search of invasive species. It was partly cloudy and misty with a temperature of 65 degrees. That afternoon A and C blocks went up from the beach and walked around the island in search of invasive plant species. The species I was searching for was Asian Bittersweet, I knew when I saw the plant strangling the birch tree it was Bittersweet. The first place I found Asian Bittersweet was 43.7764 latitude and -70.1711 longitude. I could tell it was Asian Bittersweet because first its non hollow woody vine, second bright yellowish bunches of spherical orange berries, and last glossy leaves that are almost round. Some leaves have pointed tips while others do not. Each leaf is 5 to 13 cm long and its edges are finely toothed. On Mackworth Island Asian Bittersweet looked to have caused lots of harm and is damaging the ecosystem. I know this because these plants has climbed up trees, killing limbs, and finally killing the whole tree just in search of sunlight. I don’t know how to eradicate this invasive species but if it doesn’t leave this environment soon then it will keep destroying native species and that habitat.
Supporting Evidence
Photo of my evidence.
Non-hollow woody vine, this is very different from another invasive called giant knotweed. That stem is large, green, and very hollow.
Photo of my evidence.
Bunches of bright yellowish-orange berries that are spherical in shape. This is different from the berry of another invasive Multiflora Rose were the berries are red, egg-shaped, and brown tipped.

Glossy leaves that are almost round. Some leaves have pointed tips while others do not. Each leaf is 5 to 13 cm long and its edges are finely toothed. This is different from a similar leaf that comes another invasive called glossy buckthorn. These are 3-6 cm long that are glossy, oval leaves that are alternate configuration. Last wavy edges and hairy under the bottom.

Comments

I thought this was a really good and detailed post.

Your coordinates put you in Cumberland, closer to Cousins Island, and not on Mackworth Island. Please post updated coordinates here in the comments so we can get you in the right spot on the map. Be sure to include all the decimal places.
