Field Notes
We are happy we think we found it. We saw trees, smelt air, heard cars. we are surprised because we think we found it or something close to it. We ran into some problems like we didn't know if it was the right thing because we saw a lot of red berries that looked like it.

I agree with manyeyes' comment above. It looks like you went out in the field last year, but if you do ever go back to your field site to take additional photos, it would be helpful to have a close-up of one of the stems (using a white piece of paper or your hand as a background is helpful) to show the thorns. Having a photo of your observation site that shows a whole Japanese barberry plant is also a good idea. Nice work identifying it in the winter time!

Hi Backyardigans,

Looks like Japanese barberry in your Field Notes, Evidence, and Sampling Method photos.

Your site photo is NOT Japanese barberry.

Look closely at the shape of the berries and placement along the stem to see the differences. The two leaves hanging on in your site photo also do not have the same characteristics or placement as barberry does.

If you make a photo correction (see the link above the comments "Make a Photo Correction"), I'll confirm your find!

Thanks for looking for Japanese barberry.
