Greenbrier
Posted by Anita (West Nottingham, United States) on 26 January 2008 in Plant & Nature.
Note the thorn on the left. This vine forms impenetrable thickets in nearaby woods and preserves. The berries provide food for animals.
Greenbrier is a native plant which has become invasive, like deer, and has run rampant due to the lack of natural enemies to keep it in check. Periodic hot fires used to control it naturally. Now, fires are promptly put out due to the proximity of homes. Controlled burns are used, but have limited impact. Greenbier continues to flourish, crowding out native grasses.

I welcome your honest critique, especially if they will improve my photography.
If I have made a mistake in a flower identification, please let me know!
A few words about the EXIF data, beginning in April when I began using Nikon D300 and the Sigma 105mm macro: My new camera and macro lens record the relative or effective f stop, not the one seen on the lens. For an explanation of this, go to the next to the last question at this site.

Wonderful close up - the colors in the berries are great and the depth of field perfect.

Your image has excellent light and DOF. So nice to see something other than the usual red berry shot ( of which I do have some) I like the blue here. I found your caption of interest on this being invasive to the native plants. While it provides a beautiful image I see it can have it's negative effects. Nicely done.

Thanks for this. Your narrative and your photo surprised me, for from the photo I thought of how lovely is this plant, but I see it's a more complicated situation. Anyway, it's a lovely image with a nice use of DOF.
