Generally, objects made from organic material rarely preserved. These two wood traps are also unusual because they are the only finding of their kind in wider area. The traps are incredibly interesting due to their technology, which has remained the same since the Bronze Age up to modern times.
The traps are turned upside down. A light-weight animal probably didn't trigger the trap, while a human would simply release it should they get caught. They were a type of leg-hold trap mainly used for hunting large wild game, mainly red deer.
