Field Notes
The day was Thursday, October fourth, 2018 when we went to Mackworth Island. It was mid-morning, around 10:00 when we started looking for the 6 invasive species. It was cool outside and grey and cloudy. The 6 upland invasive species we were looking for were Asian bittersweet, Japanese barberry, multiflora rose, Morrow's honeysuckle, glossy buckthorn, and giant knotweed. In our group of 6, we were assigned one species each. To find these species we were just looking around as we walked along the paths through the wood. We were able to find all of the invasive species while we walked. I noticed that some species we found l than others, for example, the Asian bittersweet and the giant knotweed. These invasive plants were everywhere. They seemed to have the biggest impact on the native species and in fact, there was ongoing control for the giant knotweed. Other plants such as the glossy buckthorn, Morrow's honeysuckle, and multiflora rose, we did not find as much, telling us that they did not have a big impact (yet) on the native species. These species could be removed soon and they wouldn’t have an impact in the future.

The leaves of glossy buckthorn are unique because they alternate but they can sometimes be opposite.

Buckthorn is tenacious and very difficult to control.
