The red-n-orange stuff is highly invasive and non-native oriental bittersweet, Celastrus orbiculatus. It's evil but also bright and pretty. It grows on the other side of the mountain from me -- we don't have it on our property that I've ever seen -- so I stole some from the horse people's roadside edge and brought it home for pictures. Then I burned the entirety of it in my woodstove to dead-dead-dead because it strangles trees. You can read more about it here.
