Field Notes
Date- 9/20/12 My group and I found it very easy to locate our invasive species. However we did not expect it to grow with in rocks and near a road. Nor did we expect it to grow in very close proximity to our native species (in the quadrat). We were having lots of fun recording our data but we did run into some problems along the way. One of which is we found it very difficult to get a high quality picture of the berries on the Japanese Barberry, which in the pictures would be hard to identify. We used our seeing sense to pick up on the oval shaped leaves and the bright vibrant red berries. We were inclined to use our sense of touch for the thrones but it is possible. Lastly we noticed that there was a road right outside of where we placed our quadrat. Our mission is to find out if there are non-native species in Falmouth that are affecting the biodiversity of our eco system. We think yes because we found an invasive species living in falmouth (Japanese Barberry), and it is effecting the biodiversity because it was found in the same area as our native species therefore invading its ecosystem.

Supporting Evidence
Photo of my evidence.
My group and I are positive that we found the Japanese Barberry, this is because one of the characteristics of the Japanese Barberry is that it has smooth oval shaped leaves growing off its stem. The plant we found also had smooth oval shaped leaves. We know we did not mistake this for the American Barberry because one the characteristics of that include pointy, serrated leaves, the opposite of what we found.

My group and I are positive that we found the Japanese Barberry, this is because one of the characteristics of the Japanese Barberry is that it has small red berries growing off of the stem in groups of one. The plant we found had those characteristics too. We know we did not mistake this for the American Barberry because one the characteristics of that include having berries growing in clumps of multiple berries, unlike the plant we found.

My group and I are positive that we found the Japanese Barberry, this is because one of the characteristics of the Japanese Barberry is that it has long thin thorns growing in one per joint of the plant. We found a plant that matched those guidelines. We know we did not mistake finding the Japanese Barberry to the American Barberry because the American grows in clusters of three per joint unlike the plant we found.

i forgot to add that the barberries look like burning-bush berries they both look the same but yeah what you have is Japanese Barberry i see alot of these in America/Indiana and in the woods. well my search continues

i haven't found out what i have yet. you have good looking pictures and a good picture of the berry. thanks for showing

American Barberry leaves can be
serrated or smooth on the edges is what i read
about and one can have green stems
and branches and with green or red
berries thats all i know about our
American Barberry plants

im sorry for any bad spelling of mine

Excellent evidence, Cold Fish 2. Your awesome photos (and sketch!) made this a quick one to confirm. Thanks for getting right to the parts that matter most in telling Japanese barberry apart from similar species.

Your Mission sounds really exciting. Tracking species like Japanese barberry over time and seeing how they impact native species is really important. Glad you're on it!

How do you think that young white pine tree in your quadrat will do over time with it's barberry neighbor?
