[Q]: The mycologist wanted to move to a rural area, to further his research, and found these two villages situated 10 miles from each other. The interesting fact about these villages was that while both villages had a forest nearby, one presented more signs of water saturation than the other, so that the rate of decay in wood was greater in Peak Forest. More fungi were present in Peak Forest. The Valley Forest was dryer, although the rain amounts were similar, partially because of a drainage system composed of ditches, that were dug by the locals.
