I submitted photos to the 'carniverous trees' category of an oak tree that grew together with a hemlock tree, such that it looked like the oak was actually biting the hemlock - even chewing on it. This was denied, because the category is written to include only trees that are devouring 'man-made' items - and I believe this would make a great post for your proposed category. Additionally, I photographed mature cedar trees at Salisbury Beach State Reservation, MA that were creatively pruned to grow sideways, downward or even in spirals - (apparently when you work for the state, in a park, you have time to kill?) and I haven't even tried to post those...
So, that would be 2 postings if you proceed. Consider me available to help write/moderate. Jim
