Japanese Barberry-  There is a forest of them on the west bank of Cook Trail behind River Cabins 15&16... they're alien, non-native, invasive species...with those nasty little thorns hiding under each leaf.  I'd love to get rid of them, but I'd need an army of volunteers working all summer to do it with tractors and the like. That whole section of Cook Trail is an absolute disaster in terms of barberry. We're talking 'acres' of infestation.  Comments by Dale Luthringer, May 2004 - photos by Ed Frank
