Field Notes
It's Monday morning about 10:15 And it's a beautiful day, around 45 degrees and partly cloudy but mostly sunny and really cold. We heard, saw, and smelled all sorts of different things. We heard cars and trucks, the chatter of other class mates, and the Riesling of the leaves. We saw different wild life, such as trees, berries, flowers, and other students. It smelled fresh and crisp, and like garbage in the morning breeze. We were very close to a road and a stream. It was a hard to identify what species our plant was because it had berries that looked the same as the Alder Buckthorn, but the leaves where a little different that was one challenge that our group had

Supporting Evidence
Photo of my evidence.
We think we found the common buckthorn because it has leaves about 8 cm long with gagged edges, and oval shaped. Also it has pairs of veins that point downward and connect at the bottom, because of these thing we think we found it.

Another piece of evidence we have is that we found a stem about 5.4 cm. And light brown with little specks. The twigs are grayish with sharp thorns at the tip.

The last piece of evidence that proves that we found the common buckthorn is the berries. The berries are a dark blue and purple color. And in the spring they flower to greenish-yellow colored flowers.

Comments

We think it may spread so fast cause birds and animals eat the berries and the berries run through the body and poop it out and is planted on the ground to make a new tree and spread again.

That is exactly right! And their poop "manure" also provides a little shot of fertilizer to help the seed that was inside the berry to grow.

Thanks for the reply!

You found Common buckthorn (Rhamnus cathartica). Not to worry. I give recognizing the leaves are different.

Smooth or glossy buckthorn has shiny leaves and does not have toothed leaves.

How do you think it spreads around so fast?

This a great web site for ID details. http://www.dnr.state.mn.us/invasives/terrestrialplants/woody/buckthorn/i...

Nice Job!
